Best use – Mechanical resistance


  • Truck bodies, trailers, dump trucks
  • High traffic and mining floors
  • Interiors of trucks, concrete mixers, salt or sand spreaders
  • Grain silos, sandblasting cabins
  • Rail, maritime and petrochemical transport
  • Ice rink alleys, sports surfaces and agricultural surfaces
  • Surfaces requiring abrasion and impact resistance



MultiFLEX 302 is a 100% pure high modulus polyurea with high mechanical strength. It is used as an abrasion resistant coating and wherever abrasion resistance and impact resistance are required. This high performance coating can be used in many application areas and on most substrates such as concrete, wood and steel.

*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.
