Application steps

MIXING

  • Mix contents of the bag (20 kg) with 3.0- 3.4 litres of clean water 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
