Bostik's Best is a one-part, trowel-applied, tacking moisture-cure, urethane adhesive; this advanced scientifically formulated adhesive does NOT contain water. Once cured, Bostik's Best is waterproof and isnot adversely affected by exposure to moisture or water; its superior properties provide a tough, flexible, tenacious bond to a variety of surfaces. Bostik's Best elastomeric characteristics allow the adhesive to move with the wood as it expands and contracts over the life of the floor.

Directions for use:
Read and understand data sheet completely before beginning installation. Follow industry standards, as well as hardwood and bamboo flooring manufacturer’s recommendations for acclimation, design, layout and application of wood flooring material. If jobsite conditions are outside of flooring manufacturer's recommendations, take necessary corrective actions. Whether the moisture content of substrate exceeds or is within the flooring manufacturer's recommendations, to address current or possible future subfloor moisture and cracks (up to 1/8"), apply Bostik's BEST for moisture vapor control as directed.

Surface preparation:
• Surfaces must be clean, dry and flat, free of voids, projections, loose materials, oil, grease, sealers and all other surface contaminants. Bostik's BEST may be used for concrete slabs as an adhesive and vapor retarder with elevated moisture levels up to 12 lbs. per 1,000 square feet per 24 hours (using an anhydrous calcium chloride test kit according to ASTM F-1869 test method), and up to 82% RH (tested in accordance with ASTM F-2170).
• For substrates that have an MVER of greater than 12 lbs or an RH greater than 82% or for substrates where a vapor barrier is not used or is not functioning below slab, use Bostik Ultra-Set® SingleStep™or Bostik MVP4/Bostik Adhesive System.
• Completely remove any adhesive residue or surface contamination by diamond grinding, shot blasting or scarifying. When diamond grinding, shot blasting or scarifying, the resulting surface texture must be similar to light broom finished concrete. Maximum acceptable floor variation is 3/16" in 10 feet. Areas requiring patching or leveling must be done using a Portland cement-based material (e.g., Bostik UltraFinish™, Fast Patch 102™ or SL-150™ Self-Leveling Underlayment).

Note: Concrete substrates should NOT be smooth and reflective; it should have a profile or broom-type surface texture for the adhesive/membrane to properly penetrate and bond.
