Polyurea Coating


Polyurea is an elastomer substance derived from step-growth polymerization, which involves combining a synthetic resin and isocyanate reactive materials. Thus, the reaction of an isocyanate part with a resin blend component part through the step growth process of polymerization produces polyurea.


  • High Flexibility

  • High Elongation

  • Waterproof

  • Fast Cure

  • Sound Dampening

  • High Impact Resistance

  • High COF

  • Used for containment

  • Reduces sound pollution

  • No cracking or warping

  • High traction

  • Protects against rust and rot

  • High cohesive properties

Compared to epoxy coating, polyurea is greatly superior in moisture resistance, UV resistance (for aliphatic coatings), abrasion resistance, chemical resistance, temperature resistance and durability. It also has a quicker cure time. Compared to polyurethane, polyurea has superior durability, chemical resistance and moisture resistance.

Approved by recognized authorities such as BARC, NPCIL.

Surface Preparation

  • New surfaces must be allowed to cure completely. It is recommended to allow 28 days as the curing time for new surfaces. Surface should be free from any loose paint, dust or grease. Growths of fungus, algae or moss should be removed by wire brushing and water. In case of areas having excessive dampness using Stanrose Damp Block to limit further dampness. When the underlying surface exhibits chalkiness, in spite of thorough surface cleaning, use Stanrocrackseal. In case of dents and holes use Stanrose Wall Putty or white cement and fine sand in the ratio 1:3.



  • Mix the constituents as per the supplied pack. The ratio of Resin to Hardner is 1:0.32 by weight. Stir the mixture properly by Electric Mixer. Apply the mixture with the help of brush or spray.
