Epic Flooring Adhesives Limitations

  • Periodically check coverage of the adhesive during the installation. 100% coverage of the substrate is required for protection from subfloor moisture. Both solid and bamboo wood flooring require a 95-100% adhesive transfer between the substrate and flooring. Engineered flooring requires a minimum 80% adhesive transfer between the substrate and the flooring.
  • Installation of unstable floorings such as bamboo or solid flooring is not recommended for below-grade applications.
  • On or below grade construction must have a functioning vapor barrier (6 mil poly or better) beneath the slab.
  • Do not install dimensionally unstable wood such as solid or bamboo over existing sheet vinyl or VCT.
  • Do not install flooring over perimeter bonded sheet vinyl.
  • Slab temperature should be between 50°F-95°F during installation.
  • Turn radiant heating or floor warming off during and for 72 hours after installation.
  • Do not use on wet, dusty, contaminated, reflective or friable substrates. Do not use on sub-floors treated with sealers or curing compounds. Do not use on concrete slabs subject to hydrostatic pressure.
  • Completely remove adhesive residue, sealers and contaminates by diamond grinding, shot blasting or scarifying.
  • Use over gypsum concrete should be limited to substrates in that are in solid condition. Do not glue down flooring over gypsum concrete that is powdery and cracked.
  • Gypsum concrete should have a minimum mix design of 2000 psi for engineered flooring and 2500 psi for solid or bamboo wood flooring.
  • Do not use to install foam backed parquet.
  • Refer to the flooring manufacturer’s recommendations and NWFA guidelines for acclimation and required expansion space as these requirements vary substantially.

IMPORTANT: Epic E-600 is designed and intended to reduce moisture vapor emissions originating from concrete subfloors. There are numerous potential sources of moisture that may damage wood flooring. Epic E-600 does not affect moisture from sides, ends or top of the flooring or humid conditions within a structure.
