Sikafloor®-21 PurCem LP

MEDIUM TO HEAVY DUTY, SELF-SMOOTHING, POLYURETHANE HYBRID FLOORING SCREED

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, smooth textured aggregate surface providing medium slip resistance and is typically installed at 3 to 6 mm thickness.

  • Good 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 Department
 
  • 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 -5 °C up to +65 °C
  • Bond strength in excess of the tensile strength of concrete. Concrete will fail first
  • Non tainting / 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
  • Can be applied to substrates with high moisture content (7 days old or mature damp concrete)
  • Jointless. Extra expansion joints are not necessary; simply maintain and extend existing expansion joints up through the Sikafloor® -PurCem flooring system
  • Easily maintained
