Sikafloor®-19 NA PurCem® FS


Sikafloor®-19 NA PurCem® FS is a trowel grade, solid color, three-component, water dispersed polyurethane based cement and aggregate mortar, designed to provide excellent resistance to abrasion, impact, chemical attack and other physical aggression. Sikafloor®-19 NA PurCem® FS can be textured aggregate surface providing moderate slip resistance. Sikafloor®-19 NA PurCem® FS Broadcast can be broadcasted with aggregate texture for increased slip resistance. Both systems are typically installed at 1/4" to 3/8'' (250 to 375 mils) thickness.

  • Can be applied on green concrete, typically 7-10 days. Full 28 days cure time is not necessary.
  • Can be applied over partially cured concrete substrates (> 4% mass (pbw –part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter surface moisture).
  • Can be applied to concrete substrates where <100 % relative humidity is measured as per ASTM F2170.
  • Substrate has tensile bond strength in excess of 218 psi (1.5 MPa). Substrate has tensile bond strength in excess of 218 psi (1.5 MPa).
  • 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 -19 NA Purcem FS 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 -40 °F (-40 °C) up to 248 °F (120 °C).
  • Steam cleanable at  1/4" to 3/8' (250 to 375 mils) thickness.
  • 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.
  • Meets the requirements of USDA for use in food plants.
