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 / curded material can only be mechanically removed.
