Best Practices for Bostik TKO Wood Flooring Urethane Adhesive

*See Terms of Use Below
1. Surface Preparation
  
  Surfaces must be clean, dry and smooth
  
  free of voids, projections, loose materials, oil, grease, sealers and all other surface contaminants. If there are any moisture related concerns, or if solid wood is being installed, completely remove cutback adhesive residue by sandblasting, shotblasting or scarifying. When sandblasting, shotblasting or scarifying, surface texture must be similar to light broom finished concrete. Maximum acceptable floor variation is 3/16” in 10 feet. Surface areas requiring patching or leveling must be done using a Portland cement based material (i.e. Bostik Fast Patch 102™, SL-150™, or SL-155 Fast Set).
2. Application
  
  Read and understand data sheet completely before beginning installation. Follow industry standards and wood flooring manufacturer’s recommendations for design, layout and application of wood flooring material.
3. Curing
  
  As you work, immediately clean any adhesive from prefinished flooring with Bostik’s Ultimate Adhesive Remover™ or mineral spirits (be careful not to harm finish) and then dry buff with a non-abrasive paper towel. Immediately clean all tools and equipment with Bostik’s Ultimate Adhesive Remover™, or mineral spirits before material cures. TROWEL CLEAN-UP TIP: Before use, cover areas of the trowel that are not used to spread the adhesive with duct tape. After use, simply tear off tape before material cures, and clean remainder of trowel with adhesive remover.
