Applications

SCHÖNOX AP RAPID PLUS is suitable for filling smoothing and leveling of substrates:

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


Substrates

SCHÖNOX AP RAPID PLUS is suitable on:

  • gypsum substrates
  • concrete, cement substrates
  • old substrates such as ceramic tiles, terrazzo, and sheet vinyl
  • old, water-resistant adhesive residues
  • 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
    • OSB board, plywood (well screwed down and/or bonded)
    • prime with SCHÖNOX SHP
  • gypsum substrates (sanded and vacuumed)
    • prime with SCHÖNOX KH FIX

  • we recommend to extend Schönox AP RAPID PLUS with dry, clean aggregate (aggregate is added last) at a layer of thickness above 2": Type and amount of aggregate used will affect product performance. As qualities of locally available aggregates vary, we recommend to perform tests prior to use on a larger scale.
