Cabot 140.0001000.007 Silicone Waterproofing Sealer 1 Gal

Product Description

The CABOT 140.0001000.007 is a silicone-formula protective sealer coating designed for indoor waterproofing applications. It applies to surfaces as a flat-finish, white coating and cures to a tack-free state in as little as 1 minute, with a full dry time of 24 hours. Coverage runs 100 to 250 square feet per gallon depending on surface porosity and application method. The VOC content is rated at 100 grams per liter, and the product ships in a 1-gallon can weighing 8.86 pounds. This type of sealer is typically applied by painting or coating contractors, waterproofing specialists, or skilled tradespeople performing moisture-control work on interior surfaces.

This product is formulated for indoor use and is suited to waterproofing applications on masonry, concrete, and similar porous substrates where surface sealing is required. It delivers a flat white finish, making it appropriate for surfaces where a low-sheen appearance is preferred. The 1-gallon container size is practical for smaller patch jobs, focused coverage areas, or jobsite testing before large-scale application. Coverage varies based on substrate texture and application technique, with a range of 100 to 250 square feet per gallon.
