Flex Paste 32 oz tub

Flex Seal Pfswhtr32 is a silicon caulk supplied in a 32 ounce white tub. It is designed for sealing and bonding tasks where a thick, paste-like consistency is preferred over liquid sealants. The product suits DIY users and maintenance crews needing a waterproof barrier for indoor or outdoor repairs. It adheres to a variety of common building materials without the mess of runny alternatives.

Capacity and application limits

The 32 ounce container provides enough volume for multiple small jobs or a single medium-sized project such as sealing window frames or plumbing fixtures. It handles gaps and vertical surfaces where slump resistance matters. Very large commercial projects will require additional tubs. The paste is not intended for structural bonding or high-temperature environments beyond standard caulk ratings.
