Protect your decking sub‑structure with Holztechnic butyl adhesive DECKUV. This self‑adhesive butyl tape forms a waterproof barrier on the top of joists and bearers, preventing standing water, capillary moisture and rain run‑off from degrading timber and fasteners. The flexible membrane conforms to uneven surfaces and self‑seals around fixings to reduce squeaks and corrosion. Built for outdoors, DECKUV is UV‑stable, weatherproof and tear‑resistant, delivering long‑term protection across seasons. The aggressive adhesive bonds strongly to timber, concrete and metal for fast, reliable application.
