Dap Inc 8640 Kitchen Bath Silicone Sealant 9.8 Oz White

Product Description

The DAP INC 8640 is a 100% silicone sealant formulated for kitchen and bath applications where a durable, watertight seal is required. It delivers high flexibility and strong adhesion to non-porous surfaces including ceramic tile and plumbing fixtures. The white formula resists mildew growth, making it well suited for wet environments where long-term sealant integrity matters. This 9.8 oz cartridge is sized for standard caulk guns and is typically installed by plumbers, tile setters, and general contractors during fixture installation, tile work, or resealing service calls.

This sealant is intended for use in residential and light commercial kitchen and bath environments. Typical applications include sealing around sinks, tubs, shower surrounds, backsplashes, and toilet bases where surfaces are non-porous. Its mildew-resistant formulation is especially useful in high-humidity areas such as bathrooms and utility rooms. The 9.8 oz tube fits standard caulk guns and is sold in cases of 12 units.

Installation Notes

Surface preparation is critical — clean and dry all surfaces thoroughly before applying sealant, removing any old caulk, soap residue, or moisture. This product is typically applied by a plumber or tile installer using a standard caulk gun. Allow full cure time before exposing the joint to water. Follow local building codes and manufacturer application guidance for joint sizing and tooling.
