Application steps

MIXING

  • Pour 5 – 6 litres (maximum) of clean fresh water into a suitable mixing container and slowly add all of the powder while mixing continuously with a Sika mixing paddle attached to a slow speed (500 r.p.m) electric drill.
  • Thoroughly mix until a smooth, lump free consistency is achieved - minimum mixing time of 3 minutes is recommended.
  • The consistency can be adjusted by using less water if desired.

APPLICATION

  • Apply Sika MonoTop® Fairing Coat (NZ) to the prepared and dampened surface according to general plastering methods using a spatula, trowel or similar.
  • Sika MonoTop® Fairing Coat (NZ) can also be applied using air driven spray equipment.
  • Maximum thickness in a single layer = 3mm.
  • If the Sika MonoTop® Fairing Coat (NZ) is to be over coated, as soon as the mortar layer has initially hardened, a fine gripping surface, comparable to sand paper, should be achieved by evenly rubbing down with a dry sponge or similar.

CLEANING OF TOOLS

Clean all tools and equipment with water immediately after use. Hands and skin should be cleaned with warm soapy water. Hardened Sika MonoTop® Fairing Coat (NZ) can only be removed mechanically.
