Zinsser WaterTite Mold & Mildew-Proof Waterproofing Paint is a low odor, oil-based water-proofing paint designed to waterproof interior and exterior concrete, stucco, cement, cinder block and other masonry surfaces. It is ideal for interior basement walls and for sealing concrete basement slabs prior to installing flooring. It is not recommended for foot traffic. It is also ideal for exterior foundations and retaining walls, above and below grade.
WaterTite Mold & Mildew-Proof Waterproofing Paint is designed to be used as a two coat system. The first coat primes and seals the surface. The second (topcoat) completes the sealing process to ensure protection against water intrusion and mildew growth on the paint film. It is not recommended for potable water tanks, cisterns, bird baths or swimming pools, or as a primer or finish on floors subject to foot traffic.
NOTE: It is not allowed to send this item through air mode. Surface mode is enabled for the same. Thus, shipping will be done through surface.
Features of Watertite Mold Mildew-Proof Waterproofing Paint

- Prevents water seepage through cement, masonry and concrete block walls and basement floor slabs.
- Prevents the growth of mold & mildew growth on the paint film lonely
- Can be applied to wet or dry surfaces
- Smooth, non-yellowing, non-grit eggshell finish
- Interior and exterior application, above and below grade
- Suitable for alkaline surfaces up to 12.5 pH
How to Apply Watertite Mold Mildew-Proo Waterproofing Paint
Surfaces must be clean, dry, sound and free of dirt, greases, soap, and other contaminants. New masonry must cure for at least 30 days before applying WaterTite Mold & Mildew-Proof Waterproofing Paint. Salting or efflorescence (a white powdery deposit often found on walls) must be removed with WaterTite Etch and Cleaner or a similar product. Follow manufacturer’s directions and safety precautions. Rinse the surface thoroughly with fresh water.
Previously Painted Surface : It can be used over previously painted, non-glossy surfaces; however its waterproofing ability is then dependent upon the integrity of the previous coating. For best results, remove as much of the old coating as possible by manually scraping the surface, followed by thorough wire rushing. A belt sander with a 50 grit sanding belt is also effective. Exterior surfaces should be power washed or abrasive blasted to remove all loose and scaling paint and cement.
Use in a well ventilated area. Extinguish all pilot lights and other sources of flames or ignition. Remove electrical equipment from the area.
Mix thoroughly to ensure any settled pigment is re-dispersed. DO NOT THIN. Stir occasionally during use. Apply only when air, material, and surface temperatures are between 50-90ºF (10- 32ºC) and the relative humidity is or less than 85%. Liberally apply the first coat using a thick polyester bristle brush, or by rolling a small section (3x3 foot) and then using a brush to work the coating into the pores of the masonry. Apply as much paint as necessary to produce a continuous, pinhole free film. Use a 1” nap roller cover for unpainted, porous surfaces or a ¾” nap roller cover for smooth or previously painted surfaces. The second coat can be brushed or rolled.
