Dap Inc 18916 Kwik Seal Ultra Kitchen Bath Sealant 5.5 Oz

Product Description

The DAP INC 18916 is a siliconized acrylic sealant formulated for high-performance kitchen and bath applications. Sold in a 5.5 oz tube in a biscuit color, it delivers a waterproof, crack-proof seal that resists mold and mildew for the life of the sealant. The formula repels water, stains, and dirt, keeping the bead looking clean over time. One of its standout working characteristics is early water exposure: the cured sealant can contact water in as little as 4 hours after application without washing out, allowing faster return to service. Low-odor formulation makes it practical for occupied interior spaces. Plumbers, tile installers, and general contractors use this product to seal joints and transitions in kitchens and bathrooms.

This sealant is designed for interior residential use in kitchens, bathrooms, and wet areas. It is safe for use on natural stone surfaces including granite and marble, making it suitable for countertop and backsplash installations where aggressive silicone chemistry could damage polished stone. The biscuit color coordinates with off-white fixtures, grout lines, and caulk joints common in residential bath and kitchen finishes. It is sold in cases of 12 units, making it a practical stocking item for contractors running multiple jobs.
