Water Repellent for Split Face Block
The Advantages of a Film-Forming Coating and Silane/Siloxane Water Repellent
MasonrySaver® Water Repellent for Split Face Block is a waterborne block sealer that causes water to shed, and significantly reduces water penetration into a wall system. It is specifically designed for lightweight, split face and fluted block.
This product is a silane/siloxane blend with acrylic elastomers that penetrate small pores and reduces the size of larger ones. This combination gives MasonrySaver® Water Repellent for Split Face Block the advantages of both a film forming coating and a hydrophobic silane/siloxane water repellent.
UV Stable
This UV stable product allows for penetration of up to 3/4 of an inch or more depending on porosity of the concrete masonry unit. This creates a deep, long-lasting waterproof zone within the surface while producing only a minimal glossy look.
Recommended Uses
This product is recommended for use on all porous, vertical, above grade concrete masonry units including:
- Smooth Block
- Split-faced Block
- Burnished Block
- Fluted Block
- Ribbed Block
- Concrete
- Brick
Natural substrate color and surface textures are only minimally affected, adding only a slight sheen and darkening. It can be used on denser clay brick where some gloss and sheen are desirable.
MasonrySaver® Water Repellent for Split Face Block can be painted over with most quality oil base paints that are recommended for exterior masonry surfaces. Coverage rates will range from 40-125 square feet per gallon depending on surface porosity. Product dries to the touch in 30 minutes to 2 hours depending on temperature and humidity. Testing is recommended before treating any surface to ensure desired results.
