Application guide

Application guide (5 easy steps)

  1. Substrate PreparationConcrete/mortar must be older than 28 days, sound, clean, dry or matt damp (no standing water), and free of laitance, oil, grease, coatings and loose particles. Steel must be de-rusted to Sa 2.5. Anchor pockets must be free of water.
  2. ConditioningCondition the material at +20 C to +30 C for at least 48 hours before use. Product must be applied at +20 C to +30 C.
  3. MixingMix components A and B for 30-60 seconds with a low-speed drill (300-450 rpm) until uniform. Transfer to a mixing vessel and slowly add component C to the correct ratio (A:B:C = 5:1:30 by weight), mixing about 3 minutes. Never mix A and B without C. Mix only complete units.
  4. Forming & PlacingSeal and release-treat forms and maintain a liquid head over 100 mm. Pour the grout from one or two sides only to avoid air entrapment, keeping the grout rising to 3 mm above the underside of the base plate. Place in lifts of maximum 150 mm.
  5. CleaningSweep excess grout into containers before it hardens. Remove uncured material with Sika Colma Cleaner; cured material can only be removed mechanically.
