Sikafloor®-29 NA PurCem®


Sikafloor®-29 NA PurCem® is a vertical grade, three-component, solid color, water dispersed polyurethane based/cement and aggregate mortar used for detailing, vertical work and coving. It has a finely textured smooth aggregate appearance that provides excellent resistance to abrasion, impact, chemical attack and other physical aggression. System is typically installed to any height from at 1/8'' to 1/4'' (125 to 250 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 -29 NA 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 -40 °F (-40 °C) up to 248 °F (120 °C).
  • Steam cleanable at 1/8'' to 1/4'' (125 to 250 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.
