Product Datasheets

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 penetrates 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 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-based 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 two hours depending on temperature and humidity. To ensure desired results, test a small area before treating any surface .
