Application steps

MIXING

  • Mix contents of the bag with clean water as recomended using a drill and spiral action mixer.
  • Always add powder to water.
  • Mix for approx. 3 minutes until a smooth, lump free flowable mortar results.
  • Do not overmix or create excessive air bubbles within the product.
  • Do not mix more product than can be used within 20 minutes.

APPLICATION

  • Pour SikaCeram®-621 FlowFix Jointing Compound into the joints immediately after mixing.
  • Using a squeegee, work SikaCeram®-621 FlowFix Jointing Compound across the tiled area ensuring all joints are filled.
  • Add more product to joints as required.
  • Ensure product has hardened sufficiently before cleaning. This usually takes between 30-60 minutes depending on site conditions. 

CLEANING OF TOOLS

  • Remove product residue from the tiled surface using a sponge float with clean fresh water.
  • Any tough areas should be scrubbed with a stiff brush then washed away once the mortar has begun to cure.
  • Do not brush over joints.
  • Once the mortar has sufficiently set, the tiled area can be polished using a dry soft cloth to remove any final mortar residues.
  • Ensure there is no residue of product left on the tiled surface.
