Blok-Guard & Graffiti Control WB 15

Blok-Guard & Graffiti Control WB 15 is a premium, water-based silicone emulsion designed to shield porous masonry surfaces from the elements—and from vandals. Ideal for concrete block, brick, unglazed terra cotta, porous tile, concrete, and select natural stone, this clear-drying formula delivers powerful weatherproofing and graffiti resistance without changing the surface’s natural look.

Perfect for both indoor and outdoor use, Blok-Guard® & Graffiti Control WB 15 keeps masonry clean, dry, and protected—making graffiti easy to remove and helping your surfaces look newer, longer.
