Use and Care Manual
PRODUCT DESCRIPTION
Rainguard BLOK-LOK with Graffiti Control is a water-based, silan-
e/siloxane graffiti & water repellent that combines high-quality
penetrating chemical solids with an acrylic surface treatment com-
ponent, to create a clear, deep-penetrating, and non-film-forming
chemically-reactive masonry water repellent that contains no sili-
cone oils, paraffin wax, or urethanes.
MICRO-LOK creates a micro-molecular chemical and mechanical
bond between the water-repellent chemicals and the
substrate. BLOK-LOK penetrates deep into porous masonry
surfaces to pro-vide long-lasting and virtually indestructible
water-repellent pro-tection that is not affected by weather or
sunlight. The acrylic surface component make graffiti easy to
remove with Rainguard’s VandlClean Graffiti Cleaner.
BLOK-LOK provides superior grade, heavy-duty graffiti and water-
repellent performance on a wide variety of vertical surfaces. This
material is Ready To Use - Do Not Dilute.
