For stopping mould growth on interior walls and ceilings, the Zinsser Perma-White Mold & Mildew Proof Interior Paint is the best overall choice. Its self-priming formula needs no sanding and creates a washable film guaranteed to resist mildew for five years. For sensitive spaces, the Sentinel 24-7 Zero Interior Coating offers a fume-free alternative, while the Rust-Oleum Mold and Mildew Proof Paint provides an excellent scrubbable finish for high-humidity rooms.
The real challenge with mould paint isn’t just covering stains, it’s preventing regrowth. A standard paint lacks the mildewcide needed to stop fungus from feeding on the paint film itself. You need a coating that bonds to the surface, resists moisture, and actively deters mould from returning.
We built this guide by analyzing manufacturer specifications, expert recommendations on moisture-resistant coatings, and patterns in owner feedback. Our goal is to help you choose a paint that solves the mould problem, not just hides it. We cover seven options for different surfaces, fume sensitivities, and application needs.

The Best Paints For Mould, Reviewed
Zinsser Perma-White Mold & Mildew Proof Interior Paint
What We Like
- Self-priming formula needs no sanding
- Mold & mildew proof film guaranteed 5 years
- Washable and scrubbable with soap and water
- Contains mildewcide to prevent growth on paint
Trade-offs
- Mildewcide only protects the paint film itself
- Quart size covers less area than a gallon
A five-year guarantee against mold and mildew on the paint film is the kind of assurance that makes this paint stand out for anyone dealing with persistent damp spots. The self-priming formula requires no sanding, so you skip that step entirely. That eggshell finish resists dirt and moisture on the film coating, and the surface is washable and scrubbable with soap and water when grime does build up. For interior walls and ceilings, this gives you a reliable defense without requiring a lot of prep work.
The mildewcide only works on the paint film itself, preventing growth on the coating you see and touch. Compared to the Zinsser WaterTite Mold & Mildew White Waterproofing Paint, which is formulated for masonry and stopping water seepage, Perma-White is suited for standard interior walls and ceilings. It is a straightforward solution for keeping mold off the surface where you just need a durable, washable finish that stays clean.
Sentinel 24-7 Zero Interior Mold & Mildew Resistant Coating
What We Like
- Zero volatile organic compounds
- Forms a durable moisture barrier
- Self-priming on prepared surfaces
- Suitable for above- and below-grade
Trade-offs
- Limited to vertical surfaces only
- Requires proper surface preparation for self-priming
- Not formulated for wood or metal substrates
Zero VOC content means this coating releases no volatile organic compounds into the air during application or drying, making it a safer choice for occupied rooms like bedrooms, nurseries, or home offices where air quality matters most. It creates a waterproof moisture barrier that works on masonry, concrete, block, and drywall. So you can use it on basement walls, bathrooms, or laundry rooms without worrying about fumes irritating your family or pets. The self-priming formula saves a step on properly prepared surfaces, and you can apply it with a brush, roller, or sprayer for flexibility on different job sizes.
The Sentinel 24-7 Zero Interior Mold & Mildew Resistant Coating has zero volatile organic compounds, so you can use it in occupied rooms without worrying about strong fumes. It also forms a durable moisture barrier that works on masonry, concrete, block, drywall, and other surfaces. Just keep in mind that this coating is designed for vertical surfaces only, so it won’t suit floors or countertops.
Rust-Oleum Mold and Mildew Proof Interior Paint
What We Like
- Washable and scrubable finish
- Self-priming, no sanding needed
- Fade resistant
- Low odor, water-based formula
Trade-offs
- Tintable only to off-white, pastel and medium colors
- At 11.9 pounds, the gallon can is heavy for overhead work
A self-priming formula that sticks without sanding makes this paint a practical choice for bathrooms and kitchens where mold-prone walls need a fresh coat fast. The washable, scrubable satin finish stands up to frequent cleaning without fading, so you can wipe away moisture and grime without worrying about damaging the paint. It suits anyone who wants a low-odor, water-based option that handles humidity while keeping maintenance simple.
The main trade-off is color flexibility: this paint tints only to off-white, pastel and medium shades, so if you want deep or vibrant hues, you’ll need to look elsewhere. For a washable mold-resistant finish in light tones, it’s a strong fit.
Zinsser WaterTite Mold & Mildew White Waterproofing Paint
What We Like
- Resists up to 20 lbs. water pressure
- Ultra low odor for indoor use
- Easy soap and water cleanup
Trade-offs
- Only for interior masonry surfaces
- Requires dry walls for application
- Heavy at 12.2 pounds per gallon
Its latex base gives a smooth, bright white finish that goes on easily with a brush or roller, and the ultra low odor means you won’t need to air out the room for days. That combination of waterproofing power and easy application is why it suits anyone tackling a damp basement or masonry wall that needs long-term protection against mold and mildew.
This paint is formulated only for interior masonry surfaces, so it won’t work on drywall, wood, or exterior walls. At 12.2 pounds per gallon, the bucket is noticeably heavier than standard paints, which can be a nuisance when carrying it down basement stairs. Compared to the Zinsser Perma-White, which is lighter and works on more surfaces, the WaterTite is the better choice when your main enemy is water pressure rather than just surface humidity.

Glidden One Coat Interior Paint with Primer
What We Like
- 100% acrylic formula
- Mildew resistant coating included
- Low VOC, low odor
- Outstanding hide and coverage
Trade-offs
- Only available in hand-selected colors
- Quart size covers up to 100 sq. ft.
A 100% acrylic paint-plus-primer that dries in 30-60 minutes and resists mildew, this Glidden one-coat formula is built for speed and protection. The mildew resistant coating means it can be used in rooms where moisture is a concern, such as bathrooms or laundry areas. It covers up to 100 square feet per quart, so a single quart handles a small accent wall or a vanity area. Low VOC and low odor keep the space livable during application. This is the pick for someone who wants a fast, all-in-one layer that fights mildew from the start.
Color choice is limited: Glidden only offers this in a hand-selected palette, so if you need a custom shade, you will have to look elsewhere. For a small project where you want a ready-to-use mildew-resistant paint that goes on fast and smells mild, this quart is a solid fit.

Rust-Oleum 2774 Paint
What We Like
- Mold & mildew-proof paint film
- Self-priming, no sanding needed
- Washable, scrubbable, stain resistant
- Low odor water-base formula
Trade-offs
- Limited to off-white, pastel, medium colors
- Not tintable to deep or dark shades
A mold- and mildew-proof paint film that resists stains and moisture means this finish stands up to frequent cleaning without degrading. The self-priming formula sticks without sanding, so you can skip that messy prep step on many surfaces. It’s water-based with low odor, keeping the room comfortable during application, and the eggshell finish scrubs clean while staying protective.
Color range is limited: it tints only to off-white, pastel, and medium shades, so deep or dark hues are off the table. If you need a dedicated mold-proof interior paint for walls and ceilings, the Zinsser Perma-White offers a similar option. But for projects that need both mold protection and a scrubbable finish on wood or metal, this paint delivers exactly what the job demands.
Pettit Paint EZ-Cabin Coat
What We Like
- Adheres to glossy surfaces without sanding
- Super tough mold and mildew-proof finish
- Fast-drying with low odor
- High-performance coating for moisture-prone areas
Trade-offs
- White only, no color options available
- Requires multiple coats for best results
The standout feature here is adhesion to glossy surfaces without sanding, which can save significant prep time on projects like trim, cabinets, or bathroom walls where moisture is a concern. The mold and mildew-proof finish is designed for moisture-prone areas, and the low-odor, fast-dry formula allows you to work without long ventilation breaks. This paint is a practical choice for anyone wanting a protective coating without the sanding step.
Only a quart is included, so painting a whole bathroom or large basement wall would require multiple units. Unlike the Zinsser Perma-White, which offers an eggshell finish, this Pettit paint is limited to white, reducing decorative flexibility. For a targeted project where adhesion to glossy surfaces is the main challenge, this paint directly addresses that problem. It is a specialist tool for a specific job, and it does that job very well.
How We Evaluated Paints For Mould
Our evaluation is research-based. We studied product datasheets, manufacturer claims about mildewcide technology, and moisture-resistance ratings. We also looked at patterns in owner feedback to understand real-world performance on common problem areas like bathroom ceilings and basement walls.
Three criteria mattered most. First, the active mould resistance, does the paint contain mildewcide that prevents growth on the film, or does it simply resist water? Second, the substrate compatibility: some paints only work on masonry, others on drywall or wood. Third, the application requirements: self-priming, sanding needs, and odor levels affect how practical the paint is for a weekend project.
A research-led evaluation has limits. Our conclusions come from specifications, expert round-ups, and what owners consistently report. This helps you narrow the field, but your specific wall condition and moisture level will ultimately decide which paint performs best.
What To Look For In Paints For Mould
Choosing the right mould-resistant paint starts with understanding your surface and moisture level. Here are the key buying criteria to consider.
Look for a paint with an active mildewcide that protects the paint film, not just a washable finish. Check the substrate compatibility, masonry, drywall, or wood, and whether the paint is self-priming. Fume sensitivity matters for occupied rooms.
Active Mildewcide vs. Moisture Resistance
Not all mould paints work the same way. Some create a waterproof barrier that stops moisture from reaching the wall, while others contain a mildewcide additive that prevents mould spores from feeding on the paint film. The best approach combines both. A paint like the Zinsser Perma-White includes a mildewcide that keeps the film itself mold-proof for up to five years. Paints that only resist moisture may still allow mould to grow on the coating over time.
Substrate Compatibility
Mould paints are formulated for specific surfaces. Masonry paints like the Zinsser WaterTite are designed for basement concrete and block walls, not drywall. General interior paints like the Rust-Oleum Mold and Mildew Proof work on drywall, plaster, and primed wood. Using the wrong type, applying a masonry paint to drywall, for example, can lead to peeling or poor adhesion. Always check the product’s approved surfaces before buying.
Application Requirements
- Self-priming paints save a step by combining primer and color in one coat, ideal for quick projects.
- Low-odor or zero-VOC formulas let you paint in occupied rooms without strong fumes.
- Washable finishes allow scrubbing with soap and water, important for kitchens and bathrooms.
- Some paints require dry walls before application; never apply to actively leaking surfaces.
For best results, apply mould paint only after fixing the moisture source, paint treats the symptom, not the leak.

Frequently Asked Questions
Can I paint over mould with mould-resistant paint?
No. You must clean and kill the existing mould first using a bleach solution or a commercial mould cleaner. Mould-resistant paint only prevents new growth on the paint film; it will not stop mould from growing underneath if the surface is not properly treated.
What is the difference between mould-resistant paint and waterproof paint?
Mould-resistant paint contains a mildewcide that prevents fungal growth on the paint film. Waterproof paint, like the Zinsser WaterTite, creates a physical barrier against water penetration. Some paints combine both features, but a waterproof coating is necessary only for walls that experience hydrostatic pressure, such as basement masonry.
Is zero-VOC mould paint effective?
Yes. The Sentinel 24-7 Zero Interior Coating proves that zero volatile organic compounds can still provide strong mould resistance. It forms a durable moisture barrier and contains mildewcide. The trade-off is that it works only on vertical surfaces, so it is not suitable for ceilings or horizontal trim.
How long does mould-resistant paint last?
Manufacturers typically guarantee the mould-proof film for five years, as with the Zinsser Perma-White. Actual longevity depends on humidity levels, surface preparation, and whether the moisture source is fixed. Washing the paint with harsh abrasives can also shorten its protective life.
Do I need a primer before using mould-resistant paint?
Many mould-resistant paints are self-priming, meaning they can go directly onto prepared surfaces without a separate primer. The Zinsser Perma-White and Rust-Oleum Mold and Mildew Proof both offer self-priming formulas. However, if the wall has stains or bare patches, a dedicated stain-blocking primer may still improve coverage.
The Bottom Line
For most homeowners, the Zinsser Perma-White Mold & Mildew Proof Interior Paint is the best overall choice. It combines self-priming convenience, a five-year mold-proof guarantee, and a washable finish that handles scrubbing. It is ideal for bathrooms, kitchens, and laundry rooms where humidity is a constant concern.
If fumes are a dealbreaker, the Sentinel 24-7 Zero Interior Coating delivers strong mould resistance without any VOCs, making it safe for bedrooms or nurseries. For damp basement walls, the Zinsser WaterTite provides actual waterproofing along with mould resistance, just make sure your walls are dry before applying.
The single most important factor in any mould paint project is fixing the moisture source first. No paint can stop an active leak. Once the wall is dry and clean, choose a paint with an active mildewcide that matches your surface, and you will have the best chance of keeping mould away for years.
