  • under flexible coverings
  • under wood floor, layer thickness at least 1/8" (use elastic adhesives only)

  • OSB board, plywood (well screwed down and/or bonded) prior to install flexible coverings.


Priming

  • porous substrates such as
    • concrete, cement substrates
    • primer with SCHÖNOX VD (1:3) or KH FIX
  • non porous, smooth, sound substrates such as
    • ceramic tiles
    • old water-resistant adhesive residues, removed as far as possible
