Self-leveling cementitious polyurethane application

PUR-CLUM Self-leveling cementitious polyurethane

PUR-CLUM is a self-levelling, medium to heavy duty, three-components; water dispersed polyurethane-based cement and aggregate screed. It is designed to provide excellent resistance to abrasion, impact, and chemical attack. PUR-CLUM can be broadcast with quartz aggregate to increase surface texture and slip resistance. The system is typically installed at 3/16 to 1/4 in (4.5 to 6 mm) thickness


  • Can be applied onto 7 to 10 day old concrete after adequate preparation and where substrate has tensile bond strength in excess of 1.5 MPa (218 psi).
  • Resists a very wide range of organic and inorganic acids, alkalis, amines, salts and solvents.
  • 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).
  • Bond strength in excess of the tensile strength of concrete, concrete will fail first.
  • Behaves plastically under impact; deforms but will not crack or debond.
  • High abrasion qualities result from its pure silica aggregate structure.
  • Highly resistant to fungi and mold growth.


  • PUR-CLUM floors are primarily used to protect concrete substrates. Typically used in food processing plants, wet & dry process areas, freezers & coolers, dairies, breweries, wineries, distilleries, laboratories, chemical process plants, pulp and paper plants, garages, warehouses and storage areas.


IMPORTANT NOTE: PROPERTIES @ 73°F (23 °C) and 50% R.H. Times are approximate and will be affected by changing ambient conditions, especially changes in temperature and relative humidity. The indicated mileage is calculated for flat surfaces. A porous or imperfect surface will require more material in order to cover the same mileage.
