Painting your walls a fresh new color can help breathe life into your home. But apart from its aesthetic appeal, you also want your paint job to last. While some wear and tear is inevitable, choosing a washable interior paint can help keep your walls looking clean and as good as new for a longer time.

As a rule of thumb, high-gloss paints are the easiest to clean, but semi-gloss, satin, and eggshell paints are also washable. Usually, flat paints aren’t washable, but a few water-based variants can be wiped clean. On the other hand, matte finishes cannot be cleaned or washed so easily. 

When selecting paint finishes for your home, you must decide which rooms are more suited to a particular paint. Here, you will find out what interior finishes are washable and which rooms are best for them.

Are all interior paints washable?

There is a basic rule when it comes to choosing paint sheens- the more shiny the paint, the more durable it will be. High-gloss paints have the most brilliance, whereas matte paints have the least. Therefore, the former is more durable, and washability is a major factor contributing to its strength.

Here is a rundown of how each paint type fares in terms of washability.

High-gloss paints

High-gloss paints dry to a hard finish and have light-reflecting properties. It is the most durable and easiest to clean out of all paint sheens. The only downside of the paint is that it highlights imperfections on the wall. However, if you prep the surface correctly, you should get quality results.

Semi-gloss paints

Semi-gloss paints are highly durable and are formulated to reflect light like high-gloss paints. However, its sheen is lesser than its predecessor. Semi-gloss paints are washable and easily cleaned thanks to their hard, shiny surface. Homeowners prefer this paint because it instantly adds luster to any object.

The only problem with the finish is that it also brings out any imperfections of the walls it’s applied to.

Satin paints

Satin finish has a subtle sheen that is often described as velvety. If you don’t prefer a lot of shine on the walls, a satin finish is perfect for your home. The paint is easy to clean and also stands up exceptionally well to scrubbing. However, its glossiness brings out imperfections like cracks or poorly patched areas.

If you plan to use satin paints, prep your walls thoroughly for a perfect finish.

Eggshell paints

The eggshell finish lies right between satin and flat paints, and it has a very subtle sheen that resembles a chicken’s egg hence, the name. These paints are durable but not as sturdy as their shinier counterparts. However, it is washable to an extent, and you can wipe off stains more quickly from an eggshell finish than from flat walls.

The upside to using this paint is that it effectively hides imperfections to give a flawless finish. It’s shinier than flat but not as glossy as satin, so an eggshell is a good option if you’re undecided on the two.

Matte or flat paints

If your walls have a story of wear and tear to tell, matte paints are your best friend. The finish can absorb light; therefore, it hides any flaws underneath. Flat paints also have the most pigment, which is why they deliver excellent coverage. The only downside to this paint is that it’s not easy to clean. So, if you get grime on your walls, chances are you will take the paint off as you attempt to wipe it.

Best washable paint for interior walls- Which finish is better for which room?

Every paint finish has different properties; therefore, one type may suit specific surfaces more than others. For example, you would want washable paint for kitchen walls, but the bedroom can get away with a less durable finish.

Let’s find out which paint type is best for individual rooms in your home.

High-gloss finish

High-gloss paints are the most durable paint for walls and the easiest to clean, making them perfect for high-traffic areas in the house. While you can use them on interior walls, the excessive shine might not be everyone’s cup of tea. But you can always use high-gloss paints in playrooms or the kitchen. In fact, this paint works best on kitchen cabinets, doors, and trims. Just make sure not to skip on prep work before applying high-gloss paint.

Semi-gloss finish

Semi-gloss paint can withstand moisture, drips, and grease stains. Since it provides a hard finish, it is a wall paint that can be wiped clean. Semi-gloss is a good candidate for high-traffic areas in the house. You can apply it on trims, chair rails, and woodwork, and it’s also ideal for rooms like the kitchen and bathroom.

Satin finish

The satin finish is washable, making it ideal for hardworking rooms such as the kitchen and bathroom. You can also apply this durable paint to family rooms, foyers, kids’ bedrooms, and hallways.

As a rule, paints with a sheen are perfect for low-lit areas or rooms that don’t get a lot of sunlight. It helps your home look bright and lively.

Eggshell finish

Eggshell paint is unsuitable for high-traffic areas like the playroom, kitchen, etc. Since it offers low to medium durability, you can use it in hallways, living rooms, and bedrooms. Eggshell paint can camouflage minor imperfections, so if you prepare the surface well, you can expect it to last a long time.

Matte or flat finish

Matte paints offer medium to low durability and should be used in low-traffic areas. Since you cannot easily wash away dirt and grime, it’s not a good candidate for bathrooms, kitchens, living rooms, or other areas more prone to stains.

However, you apply a flat finish in adult bedrooms and other spaces that are not used throughout the day. Compared to other finishes, matte paints are less durable and require high maintenance.

How to clean different types of paints on walls

Regardless of the sheen you select, a freshly-painted wall always looks immaculate. However, the same cannot be said two to three years down the lane. Your walls start showing signs of wear and tear in the form of scuff marks, spots, etc. That’s when you start wondering,’ Can I clean my walls without washing off the paint?’

Fortunately, the answer is yes! Here is a quick guide that tells you how to clean different paint finishes.

Water-based painted walls

Water-based paints are the easiest to clean. All you need is some warm water and a non-abrasive all-purpose cleaner.

1. Mix the cleaner with warm water in a bucket.
2. Fill another bucket with clean water.
3. Now, dip a sponge in the cleaner solution and gently wash the walls using the mixture.
4. Next, take another sponge and immerse it in clean water.
5. Gently wipe away the cleaner from the walls with the clean sponge.
6. Dry your walls with a towel.

This is the best way to wash water-based painted walls. However, some stains are tougher to clean. Try rubbing a paste of baking soda and water with a sponge. The stain should come right off.

Oil-based wall paints

Oil-based paints are not as easy to clean as water-based paints, but it’s not impossible. You will need liquid detergent, white vinegar, and warm water to clean the walls.

1. Mix 1 teaspoon of liquid detergent, a quarter teaspoon of vinegar, and warm water together in a bucket.
2. Dip a sponge in the cleaning mixture and gently scrub the walls.
3. Once the stain is gone, clean the area with a clean wet sponge.
4. Finally, dry the walls with a towel.

Flat wall paints

Flat finishes are the least durable and the toughest to clean. It’s better not to use any harsh chemicals, or you might strip the paint with it. Instead, wash any dirty spots with just water. You can also use a mixture of white vinegar and water but always test it on a small area to ensure it doesn’t damage the paint.

Best washable paint for interior walls

Keeping your interior paint looking fresh and clean can be challenging, but your job gets more manageable if you know what kinds of paints are washable. As a rule of thumb, premium paints are more lasting and provide truer color. In addition, they are more scrub-resistant than cheaper paints and can be washed easily.

FAQs

What does washable interior paint mean?

Many interior paints are described as washable, and what it really means is that you can wash away marks, grime, and other impurities from the wall with water.

What is the difference between wipeable and washable paint?

You can clean washable paint with soap and water, but wipeable paint can be cleaned gently using a damp cloth. Washable finishes are more durable than wipeable paint.

Is it worth buying washable paint?

Theoretically, washable paints are more durable than non-washable paints. So, if you’re buying paints that you can clean easily, you’re investing in a finish that will be lasting and easy to maintain.

How do you know if the walls are washable?

If you want to test whether your walls are washable or not, mix some dishwashing liquid with water and apply some on the corner of the wall with a clean cloth. If you see color transferring onto the cloth, your wall paint isn’t washable.

Conclusion

Buying washable paints for your interior walls is a great idea because they are easier to maintain and remain vibrant and fresh for a longer time. If you have young children at home, then you should definitely go for washable interior paints but if you prefer a matte finish over shiny ones, be prepared for more maintenance and frequent touch-ups.

I painted the outside of the house, and it faded in a couple of months. I also observed there were some places where the paint was chipped. The paint I used was fresh and nowhere close to expiry. However, upon researching and found out that I used the wrong type of paint outside. Different kinds of paints vary in properties. That is when I discovered that labeling the paint cans as interior and exterior paint is not a business strategy but an actual paint classification.

Different kinds of paints are synthesized to cater to different needs. Interior paints are adapted to stain resistance and ease of regular cleaning. Interior paints are different from exterior paints mainly due to their chemical makeup. On the other hand, exterior paints are designed to withstand weather changes. 

Can I use interior and exterior paints interchangeably? Will it save me cost or become a spilled glass of wine on a white dress? Let’s take a deep look at how the two types of paint vary as I answer all questions you may have in mind.

Compositional difference between Interior and Exterior Paints

The four main paint components are binders, pigments, additives, and bases. Variations in these lead to the differences in properties of Interior and Exterior paints.

Binders or Resins

Resins are commonly known as binders. They are the substances that hold the paint pigments with the base and make the paint adhere to the wall. 

Exterior paints are manufactured using soft resins, which can expand or contract based on weather conditions. The flexibility in exterior paints is essential to prevent cracking during the winter season. 

However, the resins used in making interior paints are inflexible and rigid. Since interior paints are not exposed to such drastic temperature changes throughout the day, the resins used here do not possess flexibility.

Exterior paints use acrylic binders, whereas silicon or epoxy binders are found in interior paints.

Additives

Modern paints incorporate various additives in the paint formula to enhance the outlook and improve the efficiency of paint. Additives can be any additional element added to the paint that is not part of the general paint formula and the dye or pigment. 

Interior paints contain leveling agents, antimicrobials, glitters, and conditioners as additives. 

Some examples of additives found in exterior paints are UV blockers and thickening agents to improve the functionality of the paint.

Pigments

Pigments are substances that give the paint its color. 

The nature of pigments in interior paints is purely organic. Due to the smaller size of organic pigments, we notice a much smoother blend in interior paints. Moreover, they are taken from plants and animal extract, thus safe to be used inside.

Exterior paints incorporate pigments derived from earthly minerals. Due to their larger size, these inorganic pigments provide a highly durable finish to the exterior walls.

Bases

The base is the solvent used to dissolve the resins, additives, and pigments. It is the key component that gives the paint its texture and allows mixing all the components to create a blend that can be applied to the walls.

There are two main kinds of bases; water base and oil base. 

Most interior paints are water-based, which allows easy cleaning and stain resistance inside the house. They also dry out more quickly than oil bases.

Exterior paints are oil-based. Oil-based paints provide water and temperature resistance; however, they take much longer to dry.

Learn more details about the composition of interior paint in our blogs.

Differences in Paint Properties

Due to the differences in composition of the paints, you can notice a difference in their properties as well. These can be measured as differences in weatherproofing abilities, durability, VOC levels etc.

Durability

On the exterior of your house, you experience stress, such as twigs falling off the trees, footballs hitting the walls, often kids running into it with their skateboards, and years of climatic distress. This demands higher durability, which is precisely how exterior paints are manufactured.

Even though interior paints can withstand a specific amount of stress, they are not as tough and durable as exterior paints.

Adhesion

Adhesion is the ability of the paint to stick to the wall surface. Interior paints require adequate priming before painting as they display excellent adherence to the primer.

You can learn about this in detail by reading our blog on the primer requirement before painting your interior. 

However, exterior paints adhere strongly to walls without primer as well. Most exterior paints will also adhere to brick or wooden surfaces; however, there will be differences in finishing when you’re not using a primer. Read more on this topic and learn whether you need a primer for your exterior walls.

Outgassing

Exterior paints have various additives to keep the paint weatherproof, temperature, moisture, and UV resistant. While exterior paints dry out, they release toxins that one must not inhale. Usually, the wind carries them away, which is not an issue while painting the exteriors.

Since interior paints have lesser additives added to the formula, they do not outgas harmful fumes.

Cleaning

Interior paints are stain resistant to keep up with the aesthetics of a clean house. Nonetheless, there can still be tough stains on the walls, perhaps your kid’s doodles. This may require heavy scrubbing, peeling off that area’s interior paint.

Exterior paints are more rigid and can resist scuffing and scrubbing better without affecting the paint.

VOC levels

Exterior paints have high VOCs compared to interior paints. These are harmful to health, and despite being highly durable, VOC emission is the main reason exterior paints cannot be used indoors.

Fade Resistance

An average house experiences sunlight for almost 12 hours a day. The rays shine bright, hitting your house at least 6 hours daily. That is a lot of saturated energy coming in contact with your house. Exterior paints incorporate additives that can withstand such strong beams of light and contain intense pigments that don’t fade away under the sun.

Temperature Resistance

The interior temperature of the house hardly fluctuates. Thus temperature resistance is not a characteristic we find in interior paints. 

Exterior paints encounter harsh temperatures, fluctuating throughout the day; thus, additional additives are added to exterior paints that make the paint temperature resistant and prevent cracking. The temperature-resistant additives are absent in interior paints, making interior paints unfit to be used on the exterior.

Moisture resistance

Exterior paints contain moisture-resistant additives to protect your house against severely fluctuating humidity, rainfall, hail, and melting snow.

Interior paints hardly undergo washing once or twice a year; therefore, moisture resistance component is absent in interior paints.

Mildew Prevention

Since the interior undergoes cleaning and disinfection regularly, molds and mildew do not build up on interior paints. Additional mildew protection is not required in the formula. Moreover, mildew preventive chemicals fume out for years and thus are unsafe to be used in interior paints. 

On the other hand, mildew is a severe risk on the exterior, and thus exterior paints contain mildew-prevention additives.

UV prevention

The sun carries heat, light, and harmful radiation, known as  UV radiation. UV radiations can bleach out pigments in your paint, causing it to fade and appear dull. Since the outer walls are exposed to the sun directly, exterior paints require UV protection. 

Interior paints do not require UV protection additives as sunlight doesn’t hit the inside walls directly.

Weatherproofing

Every time you purchase an exterior paint bucket, you’ll see a sticker that says weatherproof. Because it is the exterior that faces rain, snow, hail, dust storm, falling leaves, and harsh sunlight, they contain weatherproofing. The exterior secures the interior; thus, it does not require weatherproofing. This is why interior paints are not weatherproof.

Color Scheme

Exterior colors are in contrast to the surroundings. The most common exterior colors are gray, white, blue, autumn red, dull yellow, etc. thus, most exterior paints revolve around these shades. Interior color schemes differ as people choose colors like olive green, pastel pink, lavender, and teal, so you will find interior paints revolving around these shades. 

You can also learn more about interior paint colors and how they affect temperature. 

Cost

The cost of interior and exterior paints is quite similar; however, the difference still exists. Interior paints are more on the affordable side, whereas exterior paints tend to be a bit expensive due to the additional additives added to them. 

If you want to know the amount of interior paint you need for your house, you can go through this detailed blog. 

Similarities Between Interior And Exterior Paints

Interior paints and exterior paints are both used to paint your house. They are both made up of four essential components; resin, also known as binders, additives, color pigments, and a water- or oil-based base. 

Both these paints are available in various finishes such as matte, gloss, semi-gloss, mild shine, satin, etc., with a vast range of colors to choose from. Whether you’re painting indoors or outdoors, you need paint maintenance every 5 – 7 years.

Are interior and exterior paints interchangeable?

Since the basic makeup of interior and exterior paint is quite similar, the two most obvious questions arise. Can I use interior paint outside? Or can exterior paint be used inside? After all, they are just paints.

No, interior and exterior paints are not interchangeable. Interior paints must strictly be used inside the house, whereas exterior paints should be used on the outer walls. Not only will their efficiency as a paint be affected when used alternatively, but they can also cause serious health hazards. 

For example, interior paints outside will decrease the paint’s lifespan, as interior paints aren’t weather, temperature, or UV resistant. They will fade away faster when exposed to the sun, calling for a yearly touch-up.

Similarly, when exterior paints are used inside the house, they outgas harmful fumes that irritate the eyes, throat, and nose. Headaches, nausea, and fatigue have also been reported after exposure to the volatile compounds in exterior paints.

To avoid surpassing your yearly home maintenance budget, ensure a healthy environment, and guarantee the longevity of paint, interior and exterior paints must not be interchanged.

Frequently Asked Questions 

Is exterior paint thicker than interior paint?

Exterior paint is thicker than interior paint as exterior paints contain rigid binders and additives, increasing the paint’s density. Since exterior paint is supposed to withstand harsh conditions, it requires a thicker coat supported by the thick formula of exterior paints.

Should exterior and interior colors match?

There is no defined rule on whether exterior and interior colors should match. Your exterior color is chosen in contrast to the surroundings, whereas your interior color is chosen following the furniture. However, having similar tones will allow a smoother transition from the house’s exterior to the interior setting.

Can you DIY exterior paint?

Of course, you can! DIY painting is trending all over the world. People are taking up the responsibility to paint their own house with their families, which also leads to quality family time. However, painting requires time, patience, and expert advice to enhance your skill set and achieve a professional finish.

Can I mix interior and exterior paint?

If both the interior and exterior paints are water-based or oil-based, they can be mixed. However, water doesn’t dissolve in oil. If the bases used in the paints are different, they should not be mixed.

Moreover, exterior paints have higher VOCs than interior paints. If paints are chemically compatible for mixing, you must be careful of the ratio while mixing both the paints. 

Summing it up

Exterior and interior paints are not merely labeled on a paint can but are actual representations of the product. Interior paints differ significantly from exterior paints based on their chemical nature and usage. Exterior paints are designed to bear the harsh UV radiation and combat wear and tear due to weather changes. On the other hand, interior paint is meant to give a smooth and aesthetic finish and resist stains. They must not be used interchangeably for optimal finish, durability, and longevity.

Have you ever wondered, despite having a broad spectrum, there are limited colors on a paint sheet? Ever since I was a kid, I wanted to paint my room black, and my mom never let me. However, the grown-up me now understands the reason behind it.

Paint color contributes to the amount of energy absorbed or reflected through the walls. Yes! Interior paint color affects the temperature as darker colors absorb more heat, making rooms warmer, while lighter colors generate a cooling effect inside your rooms.

Choosing the right interior paint color can help you regulate temperature. This means establishing an energy-efficient system through the choice of colors can help you cut down on bills. Either you can use my years of experience and save some bucks on bills or continue to spend extra on energy; the choice is yours!

How does color affect temperature?

Interior temperature and the color of your walls are related. It may seem strange to people how color can help regulate temperature as well as help you save on energy costs.

Cool colors, generally the lighter shade colors, reflect the sun’s radiation, producing a cooling effect. On the other hand, warm colors, generally the darker colors, absorb 70 to 90 percent of the sun’s radiation, inducing a heated effect.

Moreover, visualizing certain colors, like the warm shades of red, yellow, and brown, can subconsciously remind us of all the hot objects like the sun and fire. This instills a warm feel, making the insides of our rooms much cozier. 

Similarly, shades of teal and blue, which fall under the cool colors category, remind us of cool things such as the morning sky, water, or tree shades, inducing a cooling effect that we can feel physically.

Can the interior paint color help you save energy?

People in hotter regions tend to use more air conditioning in their houses. Using lighter colors on the walls can reflect up to 35% of the sunlight. Reflection of sunlight means less energy is absorbed, reducing the air conditioning used inside the house. The lesser your air conditioner will be operational, the lesser will be your electricity usage.

The same goes for heating systems. For example, painting your house a darker color absorbs the sun’s energy as heat. This automatically raises the internal temperature, calling to shut off the heating systems installed.

Using appropriate colors based on your environment is a great and highly effective way to reduce energy expenditure.

Colors that make your room cooler

If you’re wondering what color makes a room feel cooler, I’ve got a little exercise for you. First, close your eyes and take a deep breath. Then, think of all the things that give you a cooling sensation. 

Most people come up with objects like the blue morning sky, water, and mint. Any light shade that appears in your imagination and gives you a cooling sensation is the color you should be going with. 

White is undoubtedly the best color for heat reflection as it reflects 98.1% heat off the surface. If you can maintain the ordinary class of white interior, keeping it clean at all times, there certainly can’t be a better option. 

However, due to a difficult maintenance routine, you can explore mint green, pastel pink, ivory, pastel green, colonial blue, pale blue, or light gray, which tops the best paint to reflect heat.

Colors that make your room warmer

Now you know that dark colors can absorb heat energy during the day, making the interior feel warmer. A warm and cozy interior is the top choice for people living in high altitudes with harsh winters. Using natural energy to heat your house is smart and energy-efficient. 

Darker colors such as mustard yellow, rich red, tangerine, gold, amber sienna, and shades of brown can absorb maximum solar energy to warm up your space. Even though black is the best absorber of heat, a black interior is unpleasant to many people’s eyes. 

Always ensure that your chosen color matches the furniture style and color. You can always add yellow lighting to make the interior appear much warmer.

Frequently Asked Questions

Should the entire house be painted the same color?

No, you should never paint the house the same color. Instead, you can use shades of the same color to connect the walls. Using the same color throughout the house makes the area look smaller, and your house may appear congested. Using different colors also adds to the aesthetic appeal of your house. 

Also, adding texture to some of your walls creates a fantastic outlook and attracts the eye. 

Are white walls in Style 2022?

White walls are the most classic color scheme inside a house. However, they still seem to trend amongst the most popular interior colors, but the new year has also brought in some textured designed walls. 

Even though the evergreen fashion of a white interior seems one of the chicest looks you can give your house, not all houses can pull off this color since it requires heavy maintenance, therefore, textured walls are trending-in.

Why shouldn’t you paint your house a dark color?

Dark-colored paints absorb more energy from the sun than lighter tones. So even though it helps regulate warmth inside the house and acts as a natural heater in winter, they absorb more UV light and heat from the sun’s radiation, causing the color to fade away quicker than usual.

Is it better to paint a house light or dark color? 

If you’re living in a warm region, light colors should be your choice to paint the house. These colors help induce a cooling effect by reflecting 35% more heat from the sun.

Dark colors, however,  are ideal for your home in cooler areas as they absorb maximum heat to warm up your house. However, dark colors fade more quickly because of the sun’s UV radiation. Thus it would be best if you select the right shade and keep them maintained.

Wrapping it up

Instead of investing money in insulation, air conditioning, and heaters, you can choose an appropriate interior paint to regulate temperature. 

Lighter paints reflect heat and lower the temperature, while dark colors absorb heat and raise the interior temperature significantly. So if you’re living in a region with a high temperature, it’s great to paint your interior light colors. 

In contrast, dark tones would be ideal for your interior if the temperature around you often drops too low.

If you’re thinking of repainting your house with a suitable color based on your region’s climatic conditions, find out about the temperature and humidity levels to paint your interiors and the best time to paint your interior here! Happy painting.

Everyone loves the look and feel of freshly painted walls but have you ever wondered what’s inside your paint? It’s important to understand what interior paint is really made of since you have to live with it every day inside your home. So, let’s find out.

Interior paint comprises four basic ingredients: pigments, binders, carriers, and additives. The pigments give the paint its hiding ability and color, while binders turn liquid paint into solid when applied to the wall. Carrier acts as the solvent, and additives help boost the paint’s performance.

Each element used in interior paints has a purpose to serve that we will explore in this article. I will also discuss different types of interior paints you can buy from the market and what makes them unique.

What are the ingredients of paint?

All paints have four essential ingredients:

• Pigments
• Binders
• Carrier (solvent)
• Additives

Here is a detailed look at what each ingredient entails.

Pigments

Pigments are finely ground insoluble particles that may be natural or synthetic. They are used in paints to add color, impart bulk, or have physical or chemical properties to the wet or dry film. Pigments comprise two basic variations:

1. Prime pigments

• Organic
• Inorganic

Prime pigments affect both wet and dry hide in paint. The whiteness in paint is achieved through the pigment Titanium dioxide, while colorants create the paint’s actual color.

Colorants can be either organic or inorganic. Organic pigments tend to form clumps or pigment particles, while inorganic pigments spread out evenly in the resin. The former is more or less transparent when we look at opacity, but the latter delivers high opacity results.

Organic variants provide brighter colors, such as phthalo blue and hansa yellow, but they aren’t very durable, which is why they’re used in interior paints. Inorganic colorants are mostly duller and earthy, like red oxide, umber, and yellow ochre. They are more resilient than their counterparts and are used in exterior paint.

2. Extender pigments

• Functional
• Special effects

Extender pigments add extra weight or bulk to the paint and contribute only to the paint’s dry hide.

Functional pigments add specific properties to the coating, like the corrosion inhibitor, while special effect pigments are responsible for creating optical effects like hammer and metallic finish.

Clay, talc, silica, diatomaceous silica, zinc oxide, and calcium carbonate are all examples of extender pigments.

Binders

The binders used in paints directly relate to its performance, washability, fade resistance, scrub resistance, and gloss retention. Binders are polymers (resins) that bring the pigments together to create the perfect dry coat of paint on a wall.

Alkyd (oil) based binders dry to a hard finish that offers superior adhesion and leveling. The downside is that it will turn yellow in light colors and oxidize on surfaces. Moreover, it contains VOCs that are harmful to human health.

Thanks to modern technology, a newer alternative is alkyd-emulsion paint which gives an oil-like performance but can water and soap solution can clean it up easily. Unfortunately, this, too, can turn yellow and chalk over time.

The following are common binders that are found in paint:

• Acrylic resins
• Alkyd resins
• Latex (PVA)
• Phenolic resins
• Urethane resins
• Epoxy resins
• Chlorinated rubber

Carrier (solvent)

The carrier is the solvent that allows the paint to be applied from the can to the surfaces. Pigments and binders are considered solids, while the carrier is a liquid. When they are all mixed together, they create the paint you see on the walls.

Carriers can be:

• Oil-based or alkyd paints that comprise paint thinner or other types of solvent.
• Water-based or latex that consists primarily of water.

If a paint contains more solids than liquid, it is considered higher in quality. So, if 35-40% of the paint remains on the wall after the solvent has evaporated, the paint will perform better. But that doesn’t mean every paint with high solids content is good. It’s the make-up of the solid elements that make a paint formula better than the others.

Additives

Additives add specific properties to the paint and improve its overall performance. The most commonly used are:

• Defoamers- to break bubbles formed during manufacturing and when applied onto a surface.
• Thickening agents- to provide additional thickness and viscosity for improved flow and leveling. It also helps reduce the splatter effect when the paint is applied with a roller.
• Biocides- to prevent bacteria from growing and to eliminate mildew growth.
• Co-solvents- to increase the liquid content in the paint. This helps the binders form a solid film when applied at low temperatures.
• Surfactants- to prevent the paint from separating. They also keep the pigments evenly distributed in the liquid resulting in better color accuracy and hiding power.

Characteristics of interior paint

1. Interior paints are used for decorative and aesthetic purposes. Since it’s used inside the home, its properties include washability, easy maintenance, and dampness prevention.
2. Interior paint is formulated to withstand abrasion, but it’s not as hard as exterior paint.
3. The paint is washable, so you can quickly wipe away roller and brush marks, as well as dirt and grime.
4. Interior paints don’t have fade-resisting properties as they don’t have to face the sun. It also doesn’t require sunlight to cure.
5. They contain a low amount of VOCs, reducing health risks and maintaining the air quality inside the home.

6 Types of interior paints and finishes

Many homeowners focus on picking the right color palettes for their homes but often don’t know the difference between various finishes. How the paint color looks on your wall greatly depends on the finish you select.

Some paints reflect light, creating a sheen on the walls, while others absorb light and make the walls look flat. A glossy surface usually highlights cracks and imperfections, whereas matte finishes camouflage flaws. The type of paint plays an integral role in its durability, coverage, and lighting within the space.

1. Matte Finish

Flat or matte paints deliver a diffused and mute color with a minimum to a soft sheen. They usually have a higher ratio of solids: liquid which helps them give deeper coverage. Also known as the concealer of paints, they work well to hide any imperfections on the walls, like nail holes, scratches, etc.

This variant is perfect for painting interior spaces like the bedroom. Since the paint is high-coverage, you don’t need multiple coats. The only downside is that matte walls can be harder to clean compared to glossy surfaces.

If you want to buy flat paint for your home, you can try the Rust-Oleum Painter’s Touch Latex Paint. I love this one because it is available in 28 exciting colors.

2. Textured Finish

If you like to add some character to their walls, textured paints are the right choice for you. These paints make your walls appear rustic and distinct, which is hard to achieve with other paints.

With textured paint, you can add depth and shadows to the walls. Since it doesn’t deliver a flat finish, it effectively masks uneven walls and other imperfections.

3. Satin Finish

Satin is right between matte and shiny; therefore, an all-rounder of wall paint finishes. These satin paints reflect more light than eggshell finishes, but they are not at all glossy. You can compare it to the shine of a pearl- soft and muted.

Satin finish feels soft and velvety to the touch and is ideal for living spaces that don’t receive a lot of sunlight. The only problem is that satin paint brings out application imperfections, unlike matte and textured finishes.

4. Eggshell Finish

As the name suggests, this paint gives a low sheen when applied to walls, just like an eggshell. It’s not entirely lusterless like matte paints and has a pleasing texture and feel. Eggshell paint hides wall imperfections like holes, bumps, etc., and offers a highly durable finish.

The finish is easier to clean than satin, making it ideal for high-traffic living spaces like the dining room, kitchen, living room, and hallways.

5. Semi-Gloss Finish

The semi-gloss is an ideal solution if you like gloss but don’t want ‘high-shine’ walls. Semi-gloss paints are shiny and reflective but not as shiny as high-gloss paints. They are durable, mildew-resistant, and easy to clean, making them perfect for playrooms, dining rooms, etc.

The only drawback is that it highlights the flaws in your walls, like satin finishes. The Montage Signature Interior/ Exterior Eco-Friendly Paint is a good option if you want a low-sheen finish. It comes in two finishes: low-sheen and semi-gloss.

6. High-gloss finish

The high-gloss finish is popular among designers and homeowners because it reflects light to give the highest sheen. Apart from being reflective, this delivers a hard finish that is highly durable. High-gloss surfaces are easy to clean, making them perfect for cabinetry, kitchen work, doors, and other objects prone to dirt and moisture.

The drawback of a high-gloss finish is that it makes any imperfections on the walls more apparent and requires several coats for full coverage.

How to choose the right paint finish for your home’s interior

Before you head out to buy paint for your DIY home paint project, you should decide the finish you want in your space. Consider these factors to help you find the perfect paint for your home.

Traffic

The first crucial thing to consider is the usual traffic in your living space. If an area is busy all the time, like playrooms and kitchens, you must get a durable paint finish and easy to clean. Semi-gloss, high-gloss, or satin finishes are perfect for such areas.

Spaces that remain relatively calmer can get away with flat and eggshell paints.

Sheen

When it comes to paint’s sheen, everyone has a different preference. But regardless of what you like, low-light or dark areas can benefit from higher-gloss finishes. If you want to make a room appear brighter and more open, go for a glossy finish. But if your living space receives plenty of daylight, you can go for any finish you like.

Walls condition

Paint helps bring life into your home, but the wrong finish can ruin a freshly-painted look. Suppose your walls have imperfections; in that case, you should choose a paint that hides them instead of highlighting them.

The more reflective a finish, the more surface imperfections will show. So, if your walls have nail holes or bumps, go with matte or satin finishes, as they help make walls appear smooth.
