  • Variance in cement can produce a shift in expected results.

  

Mixing

  • Mixing should be in accordance with the PTI Guidelines as stated in section 5.6.1 (Second edition).
  • The following order should be followed for adding the ingredients: Water, Approx. 50 % cement, SikaGrout® Aid Plus, and remaining cement.
