Vapor-Lock is a high-performance adhesive, moisture control, and sound reduction membrane all in one. Its superior properties provide a tough, flexible, and tenacious bond to various surfaces, unaffected by moisture, water, or alkalinity. Vapor-Lock exhibits exceptional green grab or high tack immediately after troweling, making installation easier and more secure.
This adhesive contains 1% recycled rubber material, has 0 VOCs (as calculated per SCAQMD Rule 1168), and does NOT contain any water. Vapor-Lock also features Bostik's BLOCKADE® antimicrobial protection, which inhibits the growth of bacteria, mold, and mildew on the surface of the cured adhesive.
