Fast Setting, Pure Polyurea Elastomeric Waterproofing Coating

  • Seamless and monolithic, including field joints
  • Excellent chemical resistance, thermal stability and UV resistance
  • Excellent impact, abrasion and puncture resistance
  • Elastic, bridge cracks on concrete surface
  • Fast turnaround time whereby coated surface can be put into service within hours
  • Aesthetically pleasing with smooth surface and can come in variations of colours

POLYSEAL POLYUREA-P is a fast setting, pure aromatic polyurea elastomeric waterproof coating. It is a two-components, 100% solid spray-applied, rapid curing pure Polyurea system. It is designed as a waterproofing coating as well as protective coating. The seamless coating provides an elastic yet tear-resistant surface for applications subjected to extreme wear and tear, strong impact and chemical exposure. Part A is the isocyanate component and Part B is the Polyurea’s amine blend.
