WATER REPELLENTS: CP-250 W

Product Data Sheet    Material Safety Data Sheet    Architectural Specification

PRODUCT DESCRIPTION

CP-250 W is an economical, multi-purpose, water-based water repellent. CP-250 W reacts with the silica in concrete and masonry in the presence of ultraviolet light and atmospheric moisture. This reaction forms strong permanent bonds beneath the surface and creates a hydrophobic zone that prevents water molecules from penetrating, while allowing free migration of water vapors. The chemical bonds formed in this process allow CP-250 W to become an integral part of the substrate and provide long-term water repellent protection.

• Solids content by weight: 5%         

USAGE

 CP-250 W can be applied to new or restored surfaces including high porosity concrete - split faced block, brick, adobe, limestone, granite, sandstone, terra cotta, stuccos & mortar. Excellent block sealer. CP-250 W can be used on most vertical exterior, above-grade  masonry surfaces. Environmentally friendly and safe for plants and animals.

BENEFITS

• Protects against water damage, staining and corrosion
• One component - no jobsite dilution or two-part mixture necessary
• Resists water penetration, even at hairline cracks
• Outstanding performance on porous substrates e.g. split-faced block
• No surface discoloration 
• Non-glossy
• Water-borne, VOC compliant
• Excellent beading effect
