Polyurea Spray Coating
Ultra-fast curing pure polyurea spray coatings. Sets in 15 seconds to form an indestructible, chemical-resistant waterproof liner for industrial slabs, secondary containment, and heavy traffic decks.
High-Performance Pure Polyurea Spray Applied Technology
Pure polyurea spray elastomer technology represents the pinnacle of protective coating and waterproofing engineering. Developed for environments requiring extreme chemical resistance, immense impact strength, and rapid turnaround times, polyurea outclasses traditional coatings across almost every mechanical metric.
IZOMATE deploys state-of-the-art plural-component hydraulic spray reactors operated by certified technicians. Our polyurea solutions protect industrial chemical processing plants, sewage treatment facilities, desalination plants, bridge decks, and high-traffic parking structures across the UAE.
Key Engineering Characteristics
- Ultra-Fast Gel Time: Reacts and solidifies in 5 to 15 seconds, allowing immediate vertical and overhead application without runs or sagging.
- Extreme Abrasion & Impact Resistance: Tensile strength exceeding 18 MPa and Shore D hardness 50+, easily resisting heavy tracked vehicles and abrasive aggregate slurry.
- Chemical & Hydrocarbon Barrier: Completely impervious to dilute acids, alkalis, crude oils, fuels, and industrial solvents.
- Zero VOCs & 100% Solids: Safe for application in semi-enclosed industrial spaces without flammable solvent fumes.
The Chemistry of Ultra-Fast Plural Component Spray Polyurea
Pure polyurea is synthesized through the direct chemical reaction between an aromatic or aliphatic isocyanate quasi-prepolymer and an amine-terminated polyether resin blend. Unlike polyurethane which relies on moisture curing (a slower reaction that can form carbon dioxide bubbles in humid air), the polyurea reaction is instantaneous, autocatalytic, and completely independent of ambient moisture and temperature.
When heated to 65°C–75°C and impingement-mixed at 2,000+ psi inside a specialized high-pressure spray gun, the material gels within 5 to 15 seconds and achieves full mechanical integrity within minutes. This enables rapid application on vertical walls, overhead ceilings, and intricate pipe manifolds without any dripping, sagging, or running.
Extreme Mechanical & Chemical Performance
IZOMATE spray polyurea systems deliver extraordinary engineering metrics that outclass generic coating options:
- Tensile Strength Exceeding 18 MPa: Resists severe hydraulic forces, structural deflection, and seismic joint movement.
- Elongation Greater than 400%: Bridges dynamic structural cracks up to 3.0mm wide even under freezing or elevated temperature cycles.
- Puncture & Tear Resistance: Shore D hardness of 50+ withstands heavy construction vehicle tracking, forklift traffic, and coarse aggregate backfill without puncture boards.
- Broad Chemical Tolerance: Impervious to continuous immersion in raw sewage, hydrogen sulfide gas, dilute acids, caustic alkalis, crude oils, and fuels.
Primary Industrial Applications Across the UAE
- Wastewater & Sewage Treatment Infrastructure: Lining concrete digestion tanks, clarifiers, and manholes against biogenic sulfuric acid corrosion.
- Desalination & Chemical Storage: Secondary containment bunds, brine channels, and industrial cooling tower basins.
- Heavy Traffic Vehicular Decks: Car park loading bays, bridge decks, and helipads requiring immediate return to service within hours of spraying.
- Underground Foundation Tanking: High-speed spray application over retaining walls in high groundwater zones.
Equipment Calibration & Plural-Component Quality Control
The application of pure polyurea requires specialized high-pressure impingement-mix equipment operating under tight technical tolerances. The isocyanate component (A-side) and polyetheramine resin (B-side) must be precisely heated to between 65°C and 75°C to achieve balanced fluid viscosities, and pumped under dynamic fluid pressures of 2,000 to 2,500 psi through heated transfer lines. Any pressure imbalance exceeding 200 psi triggers automatic machine shutdown to prevent unreacted material off-ratios.
On every IZOMATE jobsite, qualified technicians perform round-robin test shots onto plastic release sheets at the start of each shift. Gel times (10–15 seconds), tack-free times, and Shore D durometer hardness are verified and recorded in the site Quality Assurance log prior to spraying structural concrete substrates.
High-Risk Infrastructure Containment in Abu Dhabi & Dubai
In chemical manufacturing plants, municipal sewage lift stations, and coastal desalination plants, polyurea functions as the primary line of defense against biogenic sulfuric acid corrosion. Where microbial action produces sulfuric acid concentrations that dissolve standard concrete within 3 to 5 years, pure polyurea liners provide complete chemical immunity, extending infrastructure lifespans by decades.

Frequently Asked Questions
Answers to common questions regarding specifications, installation timeline, and preparation.
How quickly can a polyurea-coated surface be put back into service?
Pure polyurea cures almost instantly: it is tack-free within 15 to 30 seconds of spraying, accepts foot traffic within 10 minutes, and can be returned to full heavy-duty industrial or vehicular service in less than 2 hours.
What is the difference between pure polyurea and hybrid polyurea?
Pure polyurea is formed by the reaction of an isocyanate component and an amine-terminated resin blend, resulting in zero moisture sensitivity during application, superior tensile strength (18+ MPa), and exceptional chemical resistance. Hybrid formulations blend polyurethane polyols, reducing raw material cost but lowering chemical tolerance.
Can polyurea be applied in high humidity in the UAE?
Yes. Pure polyurea is virtually insensitive to atmospheric moisture and temperature variations during spraying, unlike polyurethane which can foam or blister if humidity is high during application.
What equipment is required to spray polyurea?
Polyurea application requires specialized high-pressure plural-component spray machines (such as Graco Reactor units) equipped with heated hoses and impingement-mix spray guns operating at temperatures of 65–75°C and pressures of 2,000–2,500 psi.
Can polyurea be sprayed on vertical walls and overhead concrete surfaces?
Yes. Because polyurea gels in 5 to 15 seconds, it can be applied in single passes up to 3.0mm thick on vertical retaining walls and overhead bridge soffits with zero sagging, running, or dripping.
What maintenance is required for polyurea-coated industrial floors and tanks?
Polyurea is virtually maintenance-free. Its non-porous, chemical-resistant surface can be cleaned using high-pressure steam washers, chemical detergents, or mechanical sweepers without damaging the coating.
