This advanced Sika Water Sealer masonry water repellent protects saves masonry surfaces from water damage by penetrating deeply into surfaces like brick, stone, and concrete.

Who This Product Is For

This water repellent is suitable for contractors, builders, and property maintenance professionals working with masonry surfaces. It is also appropriate for serious DIY users undertaking substantial exterior protection projects on homes or outbuildings.

The product suits jobs involving the protection of brickwork, render, concrete floors, and stone features from water ingress and weather-related deterioration.

Key Features

• Modern Silicone Resin Formula: Provides water resistance without the use of harmful solvents.
• Deep Penetration: Offers protection by reaching below the surface level.
• UV Resistance: Unaffected by sunlight, maintaining performance over time.
• Application Methods: Can be applied using a brush, roller, or garden spray for convenience.
• Damp Surface Compatibility: Works on both dry and damp surfaces.

Practical Applications

This water repellent protects a variety of surfaces, including:

• Masonry and brickwork to prevent moisture absorption.
• Render and pebble dash for durability against weather.
• Concrete floors in workshops and garages.
• Outdoor stone and decorative features exposed to rain and humidity.

How This Fits Into a Typical Job

This product is applied during the final protection stage of masonry work, after surfaces have been cleaned and prepared. It forms a protective barrier that prevents water ingress, typically following surface repairs or new construction, and before any decorative finishes that might be affected by moisture.

The treatment is part of a maintenance system where surfaces are cleaned, the repellent is applied, allowed to penetrate and dry, and then inspected for coverage before the area is returned to service.
