Dap Inc 750 Silicone Rubber Sealant 2.8 Oz White

Product Description

The DAP INC 750 is a 100% silicone rubber sealant formulated for kitchen and bath applications. It delivers a waterproof, flexible seal that resists moisture, mildew, and temperature swings common in wet interior environments. At 2.8 oz per tube, it is sized for targeted sealing work around sinks, tubs, shower surrounds, and similar fixtures. The sealant is white in color and is non-paintable, so it is intended for use where the finished white appearance is acceptable. It is rated for both interior and exterior use, making it suitable for a range of residential and light commercial sealing tasks performed by plumbers, tile contractors, and general tradespeople.

This sealant is appropriate for sealing gaps and joints in kitchens and bathrooms where long-term moisture resistance is required. Typical applications include perimeter sealing around lavatories, kitchen sinks, countertop edges, and tub surrounds. Its flexibility allows it to accommodate minor substrate movement without cracking or losing adhesion. The interior and exterior rating makes it usable in covered outdoor settings such as around exterior hose bibs or utility penetrations where a white silicone finish is acceptable.
