Auralex Tubetak Pro Liquid Adhesive, 10.2 oz

Tubetak Pro is the adhesive for treatment that is never coming down. It is urethane-based, loads into a standard caulking gun, and forms a permanent bond strong enough for overhead work, which is where spray adhesives lose their grip. One 10.2 oz tube covers up to 32 sq ft of foam or diffusors depending on thickness, and unlike aerosol cans it ships by air.

The other reason to reach for it is chemistry. Liquid adhesives from other makers have a history of oxidizing, effectively eating, acoustic foam; Auralex guarantees Tubetak Pro will not attack theirs. The cured bond is waterproof, heat-resistant, and impact-resistant, so it holds in garages, vehicles, and rooms that swing in temperature. Pair it with impaling clips on ProPanel walls when you want both mechanical and adhesive holding power.
