Thompsons Water Seal 5L Exterior Brick Concrete Stone Protector

Thompsons Water Seal 5L Exterior Brick Concrete Stone Protector Description

Defend your home’s exterior with the definitive 2026 standard in hydrophobic technology. Thompson's Water Seal is a professional-grade, deep-penetrating liquid engineered to provide invisible, long-lasting protection against water damage. Unlike standard surface sealants that can flake or peel, this unique formulation travels deep into dry, porous substrates to create a permanent moisture barrier.

This advanced protector forms a sophisticated breathable membrane, allowing internal moisture vapour to evaporate naturally while strictly preventing external water penetration. Designed for extreme durability, the formula is UV-stable and will not degrade under intense sunlight or heavy, persistent rainfall. It remains effective for years, ensuring your masonry stays structurally sound and aesthetically clean without changing its natural appearance.

How to Use

• Preparation: Ensure the exterior surface is thoroughly cleaned of all dirt, moss, and loose debris. The substrate must be completely dry before application to allow for maximum penetration.

• Application: Apply Thompson's Water Seal evenly using a high-quality brush or a low-pressure sprayer. Ensure all mortar joints and porous areas are fully saturated.

• Coverage: Work in manageable sections to ensure a consistent, uniform application across the entire wall or floor area.

• Drying: Allow the product to dry completely and cure before the surface is exposed to rain or moisture.

• Second Coat: For highly porous or aged materials, a second coat may be applied while the first is still slightly tacky to ensure a clinical-grade seal.

Cautions

• Exterior Use Only: This product is strictly formulated for outdoor masonry; do not use on interior surfaces or wood.

• Weather Conditions: Apply only when no rain is forecast for at least 24 hours and temperatures are above 10 degrees Celsius.

• Safety: Avoid contact with eyes and skin. If splashes occur, wash immediately with warm, soapy water.

• Storage: Keep the container upright and securely sealed in a cool, dry, frost-free location. Keep strictly out of reach of children and pets.
