DOWSIL™ Allguard Silicone Elastomeric Coating

Allguard Silicone Elastomeric Coating is a one-component, pigmented, water-based silicone elastomer designed to waterproof above-grade exterior masonry substrates, such as concrete block, fluted block, brick, stucco, synthetic stucco, poured concrete, precast concrete, Exterior Insulation Finish Systems (EIFS) and previously coated masonry substrates.

The coating is designed to maintain its water protection properties when exposed to sunlight, rain, snow or temperature extremes.

Once pigmented, it is a ready-to-use material that can be applied between 5°C and 38°C to a clean, dry surface.

AllGuard will attain full adhesion and physical properties in 7 to 14 days.
