Wood Flooring Adhesive and Moisture Vapor Retarder
TDS SDS
Where to Buy
Product overview

BST is easy-to-trowel urethane hardwood floor adhesive and moisture control membrane. It cures to form a tough, flexible, and tenacious bond with various surfaces. The elastomeric properties of BST enable it to move with the wood as it expands and contracts throughout the floor's lifespan. With exceptional green grab, BST simplifies installation by minimizing flooring slippage. This adhesive is low in VOCs (as per SCAQMD Rule 1168) and is completely water-free.
