Sikadur®-41 CF Slow

Epoxy Resin Patching Mortar

Sikadur®-41 CF Slow is a thixotropic, 3-component patching and repair mortar, based on a combination of epoxy resins and special fillers, designed for use at higher temperatures between +25 °C and +45 °C.

Sikadur®-41 CF Slow has the following advantages:
  • Easy to mix and apply
  • Very good adhesion to most construction materials
  • High strength mortar
  • Thixotropic: non-sag in vertical and overhead applications
  • Hardens without shrinkage
  • Different coloured components (for mixing control)
  • No primer needed
  • High initial and ultimate mechanical strength
  • Good abrasion resistance
  • Good chemical resistance

Application steps

SUBSTRATE PREPARATION

All surfaces must be clean, free from oil, grease, rust, scale, frost, standing water and all loosely adhering particles.
Cement laitance must be removed. Concrete must be 3 - 6 weeks old depending on climate, sand / water blasting, grinding, scrabbling are recommended.

MIXING

  • Mix components (A + B) together for at least 2 minutes with a low speed electric drill (max. 500 R.P.M.).
  • until a smooth consistency and streakfree colour are achieved.
  • Then add component (C) and continue until mixing is homogeneous.
  • Avoid entrapping air.

CLEANING OF EQUIPMENT

Clean all tools and equipment immediately after use with Sika® Colma-Cleaner.
