WATER REPELLENTS: CP-500 W Siloxane / Silane Penetrating Water Repellent

Product Data Sheet    Material Safety Data Sheet    Architectural Specification    LEED Guide

CP-500 W SILOXANE WATER REPELLENT, SILANE WATER REPELLENT:
CP-500 W is a water based, VOC compliant, penetrating water repellent which contains a proprietary modified silane / siloxane. It penetrates most masonry, concrete pores and capillaries up to 1/4 inch or more depending on surface porosity and moisture content at the time of application.

CP-500 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-500 W to become an integral part of the substrate and provide long-term water repellent protection.

USAGE:
CP-500 W can be applied to new or restored surfaces, high porosity concrete - split faced block, brick, adobe, limestone, granite, sandstone, terra cotta, stuccos & mortar. Excellent block sealer. CP-500 W can be used on most vertical or horizontal exterior, above-grade  masonry surfaces. Environmentally friendly and safe for plants and animals.
