Bostik’s BEST is a high-performance wood floor adhesive and moisture control membrane

Bostik's BEST has low VOC’s (measured per EPA Method 24) and does not contain any water. Bostik's BEST contains Bostik's BLOCKADE® antimicrobial protection, which inhibits the growth of bacteria, mold, or mildew on the surface of the dried urethane adhesive.

Get moisture protection and a wood floor adhesive

Bostik’s BEST urethane glue has very low moisture vapor permeability and is not adversely affected by moisture vapor. As a result, it will reduce moisture vapor transmission through concrete. When applied as directed as a moisture vapor membrane, it will prevent damages caused by subfloor moisture beneath dimensionally stable, engineered wood flooring only.

With Bostik’s BEST urethane adhesive, costly and time consuming concrete moisture testing is no longer required for engineered hardwood flooring when the slab is properly prepared, dry to the touch, and fully cured. For solid hardwood or bamboo on substrates >3 lbs. or 75% RH, use Bostik’s MVP4™ prior to the application of Bostik’s BEST wood floor adhesive for unlimited moisture vapor protection, or use Bostik Ultra-Set® SingleStep2™ or GreenForce®.

A urethane adhesive that moves with your subfloor for superior anti-fracture performance

The elastomeric characteristics of Bostik's BEST urethane glue establish an anti-fracture membrane that can bridge cracks up to 1/8" (3mm) which can occur in the substrate prior to or after installation. This superior elasticity allows the urethane adhesive to move with the wood as it expands and contracts with changes in humidity and temperature over the life of the floor.

Bostik’s BEST is the most versatile wood floor adhesive on the market

Bostik’s BEST urethane adhesive can be used to adhere all engineered, solid (adhesive only), bamboo (adhesive only), cork, and parquet hardwood flooring (adhesive only). Bostik’s BEST urethane adhesive may be used over all properly prepared substrates common to hardwood flooring installations including concrete, plywood, OSB, well bonded vinyl/VCT and ceramic tile, cement backer board, gypsum underlayments (dry, above-grade), cement patch/underlayments, radiant-heat flooring, and properly prepared terrazzo. This adhesive can also be used to install plywood as described below, as well as ceramic tile, marble,  and stone inlays for light commercial or residential use.

Where to Use Substrates Flooring Types
Residential Concrete Solid hardwood
Offices and light commercial Plywood Engineered hardwood
Heavy commercial OSB Bamboo
Offices Well-bonded vinyl Cork
Hospital Terrazzo Parquet
  Ceramic tile Plywood
  Cement backer board Ceramic tile, marble, and stone inlays (in residential or light commercial only)
