Dap 7079818096 Gray Concrete Waterproof Filler Sealant

Product Description

The DAP 7079818096 is a gray concrete waterproof filler sealant formulated for crack repair on concrete, mortar, and masonry surfaces. Silicone additives enhance adhesion and give the cured sealant a flexible, watertight bond that resists water intrusion over time. The gray colorway blends with standard concrete finishes, making repairs less visible on horizontal and vertical surfaces. Contractors, masons, and experienced DIYers use this product to seal cracks before they allow moisture penetration that leads to further surface deterioration. The flexible cure accommodates minor substrate movement without breaking the seal.

This sealant is suited for residential and light commercial concrete repair applications including foundation walls, driveways, sidewalks, patios, retaining walls, and masonry block surfaces. It is applied directly into cracks and joints where a durable, water-resistant fill is needed. The product ships as a single unit and is intended for use in conditions where a seamless, long-lasting repair is the primary goal.

Installation Notes

Surface preparation is critical before application — clean the crack of loose debris, dust, and standing water. This product is typically applied by masons, general contractors, or experienced tradespeople using a standard caulk gun. Follow all applicable building codes and manufacturer cure-time guidance before exposing the repair to water or traffic loads. California residents should review the Proposition 65 warning included with this product prior to use.
