Dap Inc 18897 Kwik Seal Ultra Kitchen Bath Sealant 10.1 Oz

Product Description

The DAP INC 18897 is a high-performance siliconized kitchen and bath sealant designed for interior residential applications. It delivers a 100% waterproof, crack-proof seal that resists mold and mildew for the life of the sealant. The formulation repels water, stains, and dirt, keeping the bead looking clean over time. At 10.1 oz in white, this cartridge is sized for standard caulking guns. The sealant is safe for use on granite and marble surfaces, making it appropriate for both kitchen countertop and bathroom tile work. Low odor allows use in enclosed spaces without extended ventilation downtime.

This sealant is intended for interior kitchen and bathroom applications where a durable, watertight seal is required at joints, seams, and transitions. Typical uses include sealing around sinks, tubs, countertops, backsplashes, and tile work. Because it can be exposed to water in as little as 4 hours after application, the area can be returned to service quickly compared to longer-cure alternatives. Plumbers, tile setters, and general contractors commonly use this product during fixture installs and bathroom remodels.
