Product Highlights
  • Reduces capillary water absorption of treated surfaces;
  • impregnation with an emulsion prevents reduction of heat insulation properties of the material, long resistant to effect of different factors, including alternate freezing-thawing, as well as resistant to ultraviolet and infrared rays, alternate wetting and drying;
  • penetrates deeply into the pores without clogging them, maintaining vapor permeability of the material processed;
  • does not change the appearance of material treated;
  • non-toxic.

Application Methods

At volumetric treatment

  • Unisil SE 50-94M is added into mixing water to gypsum. To achieve sufficiently reduced water absorption, use about (0,2 – 0,8) % of the emulsion from the amount of dry gypsum, or (0,1 – 0,2) % from the cement.
  • The efficiency of emulsion Unisil SE 50-94M depends on the qualitative and quantitative composition of material, so no precise advice on dosage can be given. Always provide preliminary test to determine the optimal amount of emulsion Unisil SE 50-94M.

At surface treatment Unisil SE 50-94M is diluted with water immediately before use.

  • Standard dilution: for 1 L of Unisil SE 50-94M add 9 L of water. Diluted solutions can be applied by dipping, spraying or brush. Apply working solution on a dry, clean surface until absorbed, preventing drops. Consumption depends on the porosity of the surface of the processed material.
  • Always test selected concentration of liquid on a small material sample to be sure in its suitability.
