Specification Detail MPN 54103 Brand MFM Building Products Width 3 inches Length 75 feet Color Black Adhesion Type Self-adhering Technical Features Self-adhering membrane construction: Eliminates the need for additional adhesives or mechanical fasteners during installation, reducing labor steps on the job site. Waterproof barrier design: Creates a continuous protective layer that prevents water infiltration at deck surfaces and post contact points, directly addressing moisture-related structural degradation. ACQ-compatible formulation: Engineered to perform in contact with ACQ (Alkaline Copper Quaternary) pressure-treated lumber, maintaining adhesion and integrity where standard tapes may fail. Rot and corrosion protection: Acts as a physical separator between treated lumber and hardware or adjacent materials, reducing premature deterioration caused by moisture and chemical interaction. 3" x 75' roll format: Provides a manageable, job-site-ready roll length suited for wrapping posts, beam ends, ledger boards, and deck framing members without excessive waste. Black colorway: Blends discreetly beneath decking surfaces and against treated lumber, remaining visually unobtrusive in finished assemblies. Applications Wrapping deck posts at ground contact and footing interfaces to prevent moisture wicking Protecting ledger board connections where decks attach to structure Sealing beam and joist ends exposed to weather or hardware contact Creating a protective barrier between ACQ-treated lumber and metal connectors or fasteners Waterproofing structural framing members in above-ground deck construction
