Overview

Polyurea coatings are advanced waterproofing and protective coating systems used for roof waterproofing, tank lining, concrete protection, and infrastructure rehabilitation across the UAE. Their seamless application, rapid curing, and durable performance make them suitable for commercial, industrial, infrastructure, defense, offshore, and onshore projects.

Problems this system solves

  • Recurring leaks at joints & details

    Seamless polyurea bridges cracks and movement joints with >800% elongation.

  • Long downtime for repairs

    Cures in seconds; assets back in service within hours instead of days.

  • UV, heat & chemical exposure

    Aliphatic/hybrid systems resist UV, abrasion and aggressive chemicals.

  • Tank & containment failures

    Monolithic lining for potable water, irrigation, and secondary containment.

Types of polyurea coatings

What is polyurea?

Polyurea is a two-component coating made by reacting an isocyanate with a resin blend through high-pressure heated spray equipment. It reacts within seconds to form a seamless, flexible, waterproof and impact-resistant membrane that protects concrete, steel, fibreglass and industrial substrates in demanding environments.

Pure polyurea

Contains no polyurethane additives — the highest-performing system for waterproofing and protective coatings.

  • Extremely fast cure
  • High elongation and crack bridging
  • Superior waterproofing performance
  • High chemical and abrasion resistance
  • Used on roofs, water and irrigation tanks, podiums, industrial facilities and blast mitigation

Hybrid polyurea

Combines polyurea and polyurethane chemistry to balance flexibility, adhesion and cost.

  • Improved workability and good flexibility
  • Economical, durable waterproofing
  • Used for general waterproofing, industrial coatings and maintenance systems

Aromatic polyurea

Used for internal or non-UV-exposed applications where strength and cost-efficiency matter most. Under direct sunlight the surface gradually shifts from grey to a yellow/amber tone — this is purely cosmetic and does not affect waterproofing, elongation or mechanical performance.

  • High mechanical performance
  • Excellent waterproofing
  • Cost-effective protection
  • UV exposure causes yellowing only — performance unchanged
  • Used on underground structures, tank linings and internal waterproofing

Aliphatic polyurea

Engineered for UV stability and colour retention on exposed surfaces.

  • UV resistance and colour stability
  • Weather durability
  • Decorative-finish compatibility
  • Used on exposed roofs, architectural coatings and decorative protection systems

Systems & specifications

Available systems

Pure Polyurea

100% polyurea, fastest cure, highest performance for waterproofing & lining.

  • Tensile > 16 MPa
  • Elongation > 400%
  • Cure: gel ~5s, tack-free ~30s

Hybrid Polyurea

Cost-effective blend for less aggressive exposure.

  • Slower cure window
  • Good elongation
  • Lower material cost

Aromatic Polyurea

Best mechanical properties; color shifts under UV.

  • Use under topcoat
  • Roofs, tanks, below-grade

Aliphatic Polyurea

UV-stable color and gloss retention for exposed surfaces.

  • UV stable
  • Decorative finishes
  • Topcoat over aromatic base

Key advantages

  • Seamless membrane

    No laps, no seams — monolithic across complex geometries.

  • Rapid return to service

    Walkable in minutes; full service within hours.

  • High elongation >800%

    Bridges cracks and accommodates structural movement.

  • UV & chemical resistance

    Aliphatic topcoats withstand UAE climate and chemicals.

  • Strong adhesion

    Bonds to concrete, steel and prepared substrates.

  • Certified equipment

    Sprayed with GRACO Reactor plural-component plants.

Field demonstration — Spray-applied polyurea membrane, UAE
See it in action

A monolithic membrane, sprayed in seconds.

Two-component pure polyurea is plural-component sprayed at high pressure and temperature, curing on contact to form a seamless, elastomeric waterproof membrane. No joints, no overlaps, no cold-pour failures — just a fully bonded skin that flexes with the substrate.

Frequently asked

Polyurea Coatings — answered.

Common questions from UAE consultants, clients and contractors. Need something specific? Speak with our technical team.

Polyurea is a 100% solids, plural-component elastomer that cures in seconds via amine + isocyanate reaction. Versus polyurethane it offers faster cure, higher elongation, and superior chemical/UV resistance (in aliphatic grades).
