Cons: Only comes in eggshell sheen for the interior version, quart size is small for larger rooms, must wait 7 days before scrubbing.

4. Zinsser Mold Killing Primer (Best Primer for Active Mold)
| ASIN | B00K7FEQPI |
| Price | $17.08 per quart ($0.53/fl oz) |

| EPA Reg No. | 87469-1-69587 |
| Coverage | 160 sq ft per quart |
| Dry Time | 1 hour to recoat |
This is the product to use when you have existing mold and you want to kill it before painting. The Zinsser Mold Killing Primer is an EPA registered water based fungicidal protective coating. It kills existing mold, mildew, and odor causing bacteria on the surface you paint over. It also contains an EPA registered antimicrobial to prevent future growth on the paint film.
The key difference between this primer and the PermaWhite paint is that this primer kills mold that is already present, while PermaWhite only prevents new mold on the paint film. For best results, professionals recommend using the Mold Killing Primer as a base coat, then finishing with PermaWhite paint on top. This gives you both kill power and long term prevention.
What users say: With over 4,300 ratings and 3,000+ sold per month, this is the most popular mold specific coating on the market. Users report it kills mold effectively and prevents return for months to a year. Some customers received cans where the primer had separated or expired, so check the condition when it arrives. The low odor formula makes it suitable for interior use without strong fumes.
Pros: EPA registered to kill existing mold, works as a primer under any top coat, low odor, fast drying in 1 hour, can paint directly over mold without extensive pre-cleaning.
Cons: Must fix underlying moisture issues for the mold killing to last, some reports of separated or expired product, coverage is about half that of standard primers at 160 sq ft per quart.
Who it is for: Anyone dealing with active mold spots on walls, ceilings, or trim who wants to kill the mold before applying a finish paint. Use it as the first coat before Zinsser PermaWhite for maximum protection.

The WaterTite-LX is different from standard paints. It is a waterproofing coating designed for masonry surfaces like concrete block, poured concrete, and stucco.

Buying Guide: The Specs That Actually Matter for Mold
Look for EPA Registered Mildewcides
The most important specification is whether the paint contains an EPA registered fungicide or mildewcide. This is not a marketing claim. It means the active ingredient has been tested and registered with the Environmental Protection Agency for mold and mildew control. The Zinsser Mold Killing Primer carries EPA Reg. No. 87469-1-69587. The PermaWhite paint contains an EPA registered mildewcide. Always check the label for EPA registration rather than trusting vague claims.
Self-Priming vs. Separate Primer
Self-priming paints like Zinsser PermaWhite save you an entire coat of labor. They bond directly to the surface and provide mold protection in one step. However, if you already have visible mold, you need a dedicated mold killing primer like the Zinsser Mold Killing Primer first. A standard multi-purpose primer will not kill existing mold spores.
Sheen Matters for Mold
Semi-gloss and satin finishes resist moisture better than flat or matte finishes because they have a smoother, less porous surface. Mold needs moisture and organic material to grow. A slicker sheen gives mold less surface area to cling to. For bathrooms, use at least an eggshell or satin finish. For shower walls and trim, semi-gloss is better.
Coverage and Number of Coats
Most mold resistant paints cover 300 to 400 square feet per gallon. The Zinsser WaterTite-LX is an exception at only 100 sq ft per gallon because it is a thick waterproofing coating. Two coats are recommended for every product on this list. One coat rarely provides enough film thickness to guarantee reliable mold prevention.
The 24 Hour Shower Rule
Most mold resistant paints require a waiting period before exposing the paint to direct shower steam. Zinsser PermaWhite recommends waiting 24 hours before using the shower and not scrubbing the painted surface for 7 days. The paint film needs time to fully cure before it can resist moisture effectively. Skipping this waiting period can ruin the mold protection.
Common Mistakes Buyers Make
Mistake 1: Painting Over Active Mold
Paint does not kill mold. Mold resistant paint prevents new mold from growing on the paint film. If you paint over active mold, the mold continues to grow behind the paint and eventually breaks through. You must clean and treat the mold first using a mold killing primer or a separate mold remediation product before applying mold resistant paint. The Zinsser Mold Killing Primer is specifically designed for this step.
Mistake 2: Ignoring the Moisture Source
No paint can stop mold if the room has a persistent moisture problem. A bathroom fan that vents nowhere, a leaky pipe behind the wall, or a basement with groundwater seepage will defeat any mold resistant paint eventually. Fix the moisture problem first, then paint. The WaterTite-LX can help with minor masonry seepage, but it is not a substitute for proper drainage and ventilation.
Mistake 3: Choosing Flat or Matte Paint
Flat paint absorbs moisture because it has a porous surface. In a bathroom or basement, this creates a perfect environment for mold growth. Always choose at least eggshell or satin finish for walls in high humidity rooms. Semi-gloss is best for trim and shower surrounds.
Mistake 4: Buying on Price Alone
Cheap paint from the big box store may claim to be mold resistant, but the film quality determines how long the protection lasts. Products like Benjamin Moore Aura Bath & Spa and Sherwin-Williams Duration Home use higher quality resins that create a tougher, less porous paint film. The upfront cost is higher, but the protection lasts years longer than a budget paint with a mild fungicide additive.
Mistake 5: Skipping the Primer Step
Even with self-priming paints, a dedicated mold killing primer adds a layer of protection that standard paint cannot match. The Zinsser Mold Killing Primer is EPA registered to kill mold. The PermaWhite paint is EPA registered to prevent mold. Using both products together gives you the complete system: kill what is there, then prevent what comes next.
Frequently Asked Questions
Does mold resistant paint actually work?
Yes, when used correctly. Mold resistant paint contains EPA registered mildewcides that prevent mold and mildew from growing on the paint film. It does not kill existing mold or fix moisture problems. You must clean the surface, fix the moisture source, and apply the paint according to the manufacturer instructions for it to work. Thousands of verified customer reviews confirm that products like Zinsser PermaWhite prevent mold return for months to years when applied properly.
Can I paint over mold with mold resistant paint?
You should not paint over active mold. The Zinsser Mold Killing Primer is EPA registered specifically to be applied over existing mold to kill it. After that primer, you can apply a mold resistant top coat. Standard mold resistant paints only prevent new growth on the paint film, they do not kill mold underneath. Painting over active mold without killing it first will eventually result in the mold breaking through the paint.
How long does mold resistant paint last?
The mold protection on the paint film lasts as long as the paint film remains intact and the active mildewcide is present. Zinsser PermaWhite guarantees its mold and mildew proof film for 5 years. Zinsser WaterTite-LX guarantees 10 years of mold protection. In practice, the paint should protect for several years as long as the underlying moisture problem is controlled. If moisture returns, the protection will be overwhelmed.
What is the best finish for mold resistant paint in a bathroom?
Satin or semi-gloss finishes work best in bathrooms. These finishes create a smoother, less porous surface that resists moisture absorption. They are also easier to clean with soap and water. Flat or matte finishes are not recommended for bathrooms because they absorb moisture and provide more surface area for mold to grow on. If you want a low sheen look, eggshell is the minimum sheen level that still provides reasonable moisture resistance.
Is mold resistant paint worth the extra cost?
Yes, for high humidity rooms. Standard interior paint costs $20 to $40 per gallon. Mold resistant paint costs $15 to $110 per gallon depending on the product. The price difference is small compared to the cost of cleaning mold damage, repainting, and potentially replacing drywall. The Zinsser PermaWhite at $15.75 per quart is actually cheaper than many standard paints when you factor in that it is self-priming and does not require a separate primer coat. For bathrooms, basements, and laundry rooms, mold resistant paint is a smart investment.
