* Polyurea reaches its full maturity after a few weeks, varying according to the type of product and the different environmental conditions.
** If the time is exceeded, the use of a surface activator is necessary to apply another coat.


  • Increased resistance to chemicals, oils, solvents and wastewater
  • High tear resistance
  • High adhesion on a wide variety of surfaces
  • A non-stick surface that helps slip
  • High hardness and high tensile strength
  • Waterproof

*The values indicated on this technical data sheet are based on tests produced under laboratory conditions. Equipment configurations as well as application conditions can produce deviations in the values of the final system. The user is responsible for the resulting performance and for ensuring that the product is what is needed for the application he intends to do with it. For best results, these settings should be used.

Surface preparation

Make sure you have a ready application surface free of dirt, dust, oil, grease or any other contaminant before you begin. A CSP-4 through CSP-5 surface profile is required for application to concrete to achieve the best possible adhesion, producing a profile equivalent to 60 grit sandpaper or coarser. In addition, make sure that the surface is dry and that the air temperature exceeds that of the dew point. If the product is applied to a concrete surface, a cure time of approximately 28 days is recommended for optimum adhesion. In some cases, the use of a primer may be necessary. Please see the MultiFLEX Application Guide for details on application, surface preparation and recommended thickness.
