Sikafloor®-19 NA PurCem® FS


Sikafloor®-19 NA PurCem® FS solid color, three-component, water dispersed polyurethane-based/cement and aggregate screed, designed to provide excellent resistance to abrasion, impact, chemical attack and other physical aggression. Sikafloor®-19 NA PurCem® FS has a textured aggregate surface providing moderate slip resistance. Sikafloor®-19 NA PurCem® FS Broadcast has a broadcast aggregate texture for increased slip resistance. Both systems are typically installed at 1/4 to 3/8 in (6 to 9 mm) thickness.

  • Can be applied on green concrete (typically 7 -10 days) after preparation (see surface prep section) and where substrate has tensile bond strength in excess of 218 psi (1.5 MPa).
  • Can be applied to concrete substrates where <100% relative humidity is measured as per ASTM F2170.
  • Resists a very wide range of organic and inorganic acids, alkalis, amines, salts and solvents. Consult Sika Technical Service for full details. Refer to the Sikafloor PurCem Chemical Resistance Chart.
  • 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 -37°F (-37°C) up to 248°F (120°C).
  • Steam cleanable at 1/4 - 3/8 in (6 - 9 mm) thickness.
  • Bond strength in excess of the tensile strength of concrete, concrete will fail first.
  • Non-tainting, odorless.
  • Behaves plastically under impact / deforms but will not crack or debond.
  • High abrasion qualities result from its aggregate structure.
  • Extra  Expansion  joints  are  not  necessary; maintain  and  extend  existing expansion joints up through the Sikafloor PurCem Flooring System.
  • Minimal maintenance costs, superior life cycle cost advantage versus tile.
  • Achieves highest performance ratings according to ASTM G21 resistance to fungi and ASTM D3273 resistance to mold growth.
  • Meets the requirements of USDA for use in food plants.
