Sikafloor®-24 NA PurCem®

Advanced Generation Self Leveling Thin Layer Polyurethane/Cement Slurry for     General Industrial and Commercial Use

Sikafloor®-24 NA PurCem® is a state of the art, phthalate-free, water dispersed polyurethane based/cement and aggregate screed, applicable at thicknesses ranging from 80 to 160 mils (2 to 4 mm). It is designed to be installed as a self leveling floor topping that provides an easy-to-clean, smooth surface with slip resistance and is typically used for general, industrial applications. Sikafloor®-24 NA PurCem® represents superior polyurethane/cement technology, combining easier application, resistance to blistering and improved performance.

  • 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 over partially cured concrete substrates, full 28 days cure time is not necessary.
  • Easy installation requiring less labor to install than traditional Sikafloor® PurCem® trowel and heavy duty slurry grade materials
  • Can be applied to concrete substrates where <100% relative humidity is measured as per ASTM F2170.
  • Wide range of application temperatures from 45°F (7°C) minimum to 100°F(38°C ) maximum.
  • 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.
  • Good abrasion resistance, providing cost effective and durable floor topping.
  • Similar coefficients of thermal expansion to concrete allowing movement with the substrate through normal thermal cycling.
  • Performs and retains its physical characteristics through a wide, wet or dry temperature range from 23°F (-5°C) at 2.0 mm and 14°F (-10°C ) at 4.0 mm up to 248°F (120°C).
  • Superior formulation eliminates formation of blisters, such as those arising out of application during elevated temperatures or early and multiple layer applications.
  • Non-tainting, odorless and phthalate-free, avoiding associated toxicity to health and environmental hazards.
  • Bond strength in excess of the tensile strength of concrete, concrete will fail first.
  • Compatible with a wide range of Sikafloor epoxy or polyurethane resin sealers, enabling UV- stable sealers to be applied where required.
  • Consult Sika Technical department for full details.
  • Minimal maintenance costs, superior life cycle cost advantage versus tile.
  • Maintain and extend existing expansion joints up through the Sikafloor PurCem Flooring System.
  • Behaves plastically under impact / deforms but will not crack or debond.
  • 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.
