Weldlok® OnGuard is a revolutionary moisture barrier backing that is integrated into our Weldlok® standard broadloom backing system. This advanced moisture barrier passes both the British Spill test along with 10,000 impact testing. This backing system utilizes a specialized water resistant sheath to prevent any moisture from getting beneath the carpet backing. When installed using Mohawk Group’s Nubroadlok® Premium Multi-Purpose Adhesive and LifeLoc® Seam Sealer, Weldlok® OnGuard forms a fortified barrier to safeguard from spills.
