Is a clear-drying, water-based silicone emulsion for weatherproofing concrete block and
other porous masonry materials. Blok-Guard® & Graffiti Control II also protects masonry
surfaces from graffiti attacks without altering the natural appearance. Blok-Guard® &
Graffiti Control II protects exterior walls exposed to normal weathering. Graffiti removal
from treated surfaces is fast and easy using Defacer Eraser® Graffiti Wipe. Blok-Guard®
& Graffiti Control II is easy to apply with low-pressure spray, brush or roller.
Sacrificial Coating SC-1
Is a clear, water-based sacrificial coating for control of graffiti on most building surfaces.
SC-1 acts as a graffiti barrier, preventing spray paints, crayons and ink from penetrating
and staining the underlying surface.Graffiti is removed from protected surfaces by
high-pressure hot water, Defacer Eraser® Graffiti Wipe or Sure Klean® Fast Acting
Stripper.

The coating must then be reapplied to restore the graffiti barrier. SC-1 allows
cost-effective control of chronic graffiti without chemical strippers or abrasives that can
damage building surfaces or the surrounding environment. It allows protection of limited
areas and spot reapplication without a noticeable change in overall color or appearance.
SC-1 complies with all known regulations limiting Volatile Organic Compound (VOC)
content. The coating is formulated as a water-thin liquid for spray application to porous
and textured surfaces.
