Application steps

SUBSTRATE QUALITY

Mortar and concrete must be older than 28 days.
Adequate substrate strength (concrete, masonry, natural stone) must always be confirmed.

MIXING

Getting the Cartridge Ready:

  • Unscrew and remove the cap.
  • Pull out the plug.
  • Screw on the static mixer.
  • Place the cartridge into the gun and start application.


IMPORTANT NOTE:  When the work is interrupted, the static mixer can remain on the cartridge after the gun pressure has been relieved. If the resin has hardened in the nozzle when work is resumed, a new nozzle must be attached.

CLEANING OF TOOLS

Clean all tools and application equipment with Sika® Thinner C immediately after use. Hardened / cured material can only be mechanically removed.
