Water-based primers dry faster and have low odor. They are easier to clean up and more eco-friendly.

Application Tips For Best Results
Applying Zinsser Mold Killing Primer correctly ensures the best stain blocking and mold-killing results. Proper technique improves adhesion and coverage. Follow these simple tips for a smooth, effective application.
Surface Preparation
Clean the surface thoroughly before applying the primer. Remove loose paint, dirt, and mold with a brush or detergent. Let the area dry completely. Repair any cracks or holes for a smooth finish. A clean, dry surface helps the primer stick better and work effectively.
Primer Application Techniques
Use a brush, roller, or sprayer to apply the primer evenly. Start with thin coats to avoid drips and runs. Work in small sections, spreading the primer smoothly. Overlap strokes slightly to cover all areas. Allow each coat to dry fully before applying the next.
Number Of Coats Needed
Apply at least one full coat for light stains. For heavy stains or mold spots, two coats may be necessary. Check coverage after the first coat dries. Add another coat if stains still show through. Proper layering blocks stains and kills mold effectively.
Painting Over Zinsser Mold Killing Primer

Many wonder if adding a topcoat is essential and how to select the right paint to ensure lasting protection and appearance.

Is Painting Necessary?
Zinsser Mold Killing Primer creates a solid, protective layer on surfaces. It can stand alone without a topcoat in some cases. The primer has a clean, white finish that resists mold growth. For high-traffic or moist areas, painting over it adds extra durability. Painting also improves color and texture. Skipping paint may leave the surface less protected from wear.
Choosing Compatible Topcoats
Select a paint that bonds well with the primer. Latex and acrylic paints work best with Zinsser Mold Killing Primer. They provide good coverage and flexibility. Avoid oil-based paints unless the primer instructions allow them. Using compatible topcoats prevents peeling and ensures strong adhesion. Pick paints designed for bathrooms or kitchens for added moisture resistance.
Drying And Curing Times
Allow the primer to dry fully before painting. Drying usually takes about one hour, but curing may need up to 24 hours. Curing strengthens the primer’s stain blocking and mold killing properties.
