M-D Building Products Prova Seal 9.5 Oz. Siliconized Sealant, White

PROVA-SEAL is a single-component, premium hybrid silicone sealant that can be used to waterproof pipe and valve protrusions in PROVA shower systems and is for use with PROVA BOARD PLUS. Once cured, PROVA-SEAL provides a watertight, flexible seal. The cured product will not crack, crumble, or shrink, and it adheres to most common construction materials: wood, metal, vinyl siding, masonry, concrete, brick, tile, plastic, drywall/plaster, glass, and painted surfaces. Once applied, PROVA-SEAL can be painted in 30 minutes and exposed to water in one hour.
