Protects concrete from the effects of water, deicing salts
and other waterborne chemicals. Keeps concrete and other
substrates, including stucco, sandstone, terra-cotta, hand
molded bricks and some natural stones, clean by reducing the
amount of dirt and other pollutants that may be absorbed.
Prevents moisture absorption in brick masonry, especially
single wythe wall construction. Protects concrete masonry
units (medium- to normal-weight split-face, fluted or ground
faced blocks) from the ingress of wind-driven rain.
