Biokil Crown Water Repellent is a clear, solvent-based treatment designed to protect masonry surfaces from penetrating damp. Formulated with polyoxo aluminium stearate in white spirit, it penetrates deeply into substrates, providing long-lasting protection while allowing the surface to breathe.

Key Features & Benefits

Long-Lasting: Provides up to 10 years of protection with proper application.
Versatile Application: Suitable for use on concrete, roughcasts, renders, sandstone, synthetic stone, bricks, and aerated concrete.
Prevents Biological Growth: Reduces the growth of moss, algae, and lichen by keeping surfaces dry.
Maintains Appearance: Does not alter the color or reflectance of the treated surface.

Product Details

Base: Polyoxo aluminium stearate in white spirit.
Coverage: Approximately 2–5 m² per litre per coat, depending on substrate porosity.

Application Instructions

Surface Preparation: Ensure surfaces are clean, dry, and free from contaminants. Remove any loose material, dirt, or biological growth.
