Sikafloor®-21 PurCem®

Sikafloor®-21 PurCem® LP is a three part, water dispersed medium to high strength coloured polyurethane modified, cement and aggregate screed with self-smoothing properties. It has an aesthetic, easy to clean, smooth textured aggregate surface providing medium slip resistance and is typically installed at 2 to 4 mm thick.

  • Excellent chemical resistance. Resists a wide range of organic and inorganic acids, alkalis, amines, salts and solvents. Please refer to the Chemical Resistance Chart or consult your local Technical Dept.
  • Similar coefficient of thermal expansion to concrete, allowing movement with the substrate through normal thermal cycling. It will perform and retain its physical characteristics through a wide temperature range from -5C up to +65C
  • Bond strength in excess of the tensile strength of concrete.
    Concrete will fail first
  • Non taint, odourless
  • VOC free
  • High mechanical resistance. Behaves plastically subject to impact. Will deform but will not crack or debond.
  • High abrasion resistance resulting from its silica aggregate structure
  • It is possible to apply n to 7 to 10 day old concrete after adequate preparation and with a tensile bond strength in axcess of 1.5 Mpa
  • Jointless. Extra expansion joints are not necessary; simply maintain and extend existing expansion joints up through the Sikafloor® -PurCem® flooring system
  • Easily maintained
