Application steps

SUBSTRATE PREPARATION

SURFACE PREPARATION
Surface must be clean, sound and properly cured. Remove all loose materials mechanically, preferably with a wire brush. Iron and steel surfaces should be free of rust.

APPLICATION

For Wall (Without Membrane):

  • For porous substrate, apply first coat diluted with 10% water as primer layer. Allow enough drying time (>3 hours).
  • Apply SikaCoat® in two coats by brush and roller

For Detailing Area (With Membrane):

  • For porous substrate, apply first coat diluted with 10% water as primer layer. Allow enough drying time (>3 hours).
  • Apply a first coat (0.8 - 1 kg/m2) of SikaCoat® by brush or roller.
  • Embed the SikaCoat® membrane into the first coat while it is still wet. Ensure that the membrane is thoroughly embedded and smooth out all air pockets and creases. Overlaps of adjacent membrane must be a minimum of 50 mm.
  • Immediately apply a second coat (0.8 - 1 kg/m2) of SikaCoat® while the first coat is still wet, to fully saturate the membrane from both sides.
  • When dry, apply a final top coat (~0.4 kg/m2) to complete the application. Protect from rain until dry.

CLEANING OF TOOLS

Remove uncured surface SikaCoat® with water. Cured material can only be removed mechanically.
