Bostik Ultraset 2in1 Timber Flooring Adhesive
Description

Bostik Ultraset 2in1 is a one-part, solvent-free timber flooring adhesive featuring AXIOS® Tri-Linking Polymer Technology with an integrated moisture vapour barrier. Designed for the installation of solid timber, engineered timber, parquet and bamboo flooring, it provides a high-strength, flexible bond while helping protect timber flooring from residual substrate moisture, eliminating the need for a separate moisture barrier in many applications.
