Application steps

MIXING

  • Mix SikaLatex® with the correct amount of water to produce a gauging solution.
  • Pour part of the gauging solution into a suitable mixing container.
  • While mixing slowly, add the mortar mix to the gauging solution and mix thoroughly until a smooth, uniform and lump-free mix is achieved.
  • Within the mixing time add additional gauging solution to adjust to the desired consistency.
