ADHESIVES

Bostik’s BEST is a urethane adhesive and moisture control membrane designed for superior performance. This high-tack formula ensures a strong, flexible bond to various surfaces, making it ideal for demanding installations. With exceptional green grab right after troweling, Bostik's BEST simplifies the installation process, providing a secure and reliable bond.

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.

EFA+ is an easy-to-trowel urethane adhesive and moisture-control membrane. It offers a flexible and tenacious bond to various surfaces. The elastomeric properties of EFA+ allow it to move with the wood as it expands and contracts throughout the floor's lifespan. With a long open time, EFA+ simplifies and speeds up the installation process. This adhesive is low in VOCs and completely water-free.

GreenForce is a high-performance adhesive, sound reduction membrane, and moisture vapor control membrane all in one. Utilizing Bostik’s innovative AXIOS® Tri-Linking Polymer Technology, this formulation ensures superior long-term durability and moisture vapor protection typical of high-end urethane adhesives. Additionally, it is easier to spread on and clean off prefinished flooring both before and after curing.

This adhesive has zero VOCs (as calculated per SCAQMD Rule 1168) and does NOT contain any water. GreenForce also features Bostik’s BLOCKADE® antimicrobial protection, which inhibits the growth of bacteria, mold, and mildew on the surface of the cured membrane, effectively resisting stains caused by mold.

MVP4 Moisture Vapor Protection is a one-part, trowel-applied, moisture-cure urethane membrane designed for use beneath glue-down installations of engineered, solid, and bamboo hardwood flooring. MVP4 is exceptionally easy to trowel and minimizes moisture vapor transmission from the subfloor. It creates a noise reduction barrier over the substrate and establishes an anti-fracture membrane that can bridge cracks up to 1/8" in the substrate before or after installation. MVP4 can be applied prior to any Bostik hardwood adhesive to achieve a warranty for unlimited moisture vapor protection.

This membrane is low in VOCs (as per SCAQMD Rule 1168) and completely water-free. MVP4 features Bostik’s BLOCKADE® antimicrobial protection, inhibiting the growth of bacteria, mold, or mildew on the cured membrane surface. The cured membrane also resists stains caused by mold.

Ultra-Set SingleStep2 is a high-performance adhesive, moisture control, and sound reduction membrane all in one. Utilizing Bostik’s innovative AXIOS® Tri-Linking™ Polymer Technology, this formulation ensures superior long-term durability, moisture control, and sound abatement properties typical of high-end urethane adhesives. Additionally, it is easier to spread and clean off prefinished flooring both before and after curing.

This adhesive contains 1% recycled rubber material, has zero VOCs (as calculated per SCAQMD Rule 1168), and does NOT contain any water. Ultra-Set SingleStep2 also features Bostik’s BLOCKADE® antimicrobial protection, which inhibits the growth of bacteria, mold, and mildew on the surface of the cured membrane, effectively resisting stains caused by mold.
