Performance & Benefits

Exceptional Waterproofing Power
Zinsser WaterTite is guaranteed to keep water out, stopping water pressure up to 34 psi — roughly equivalent to moderate hydrostatic pressure — which dramatically improves resistance to damp and seepage on walls and floors.

Applies to Wet or Dry Surfaces
Unlike many waterproofing paints, WaterTite can be applied to dry, damp or slightly wet masonry, enabling immediate remediation of water issues without waiting for complete surface drying.

Prevents Recurring Efflorescence
The formulation helps prevent recurring efflorescence (white salt deposits on concrete and brickwork), maintaining a clean finish over time.

Mould & Mildew Resistance
Containing a biocide, the dried film is resistant to mould and mildew growth on the paint surface, enhancing long-term performance especially in humid environments.

Interior & Exterior Use
Suitable for both above- and below-grade applications, WaterTite is ideal for basements, retaining walls, foundations and other areas prone to damp or leaks.

Recommended Applications

Use WaterTite to waterproof and protect:

• Basement and cellar walls

• Concrete and cement floors (non-traffic areas)

• Brick and blockwork walls

• Rendered and masonry surfaces

• Retaining walls and exterior foundations

Surface Preparation & Application

1. Prepare: Ensure surfaces are free of loose material, dirt, grease and soap residues.

2. Remove Efflorescence: Treat white powdery deposits with appropriate cleaners and rinse well.

3. Stir Well: Mix thoroughly before and during application.

4. Apply: Use a brush or roller to apply liberally, working the product into masonry pores.

5. Dry & Recoat: Allow ~4 hours between coats; two coats are recommended for full waterproofing.

6. Cure: Full waterproof protection develops over ~7–14 days.
