Everything You Need to Know

Overview

Polyurea waterproof coating is a liquid-applied elastomeric coating based on polyurea (PUA) chemistry that reacts and cures in place to form a seamless, fully bonded waterproofing membrane with no laps, no joints and no weak points. It combines extremely fast curing, high elasticity and outstanding chemical and abrasion resistance, and is widely used for roofs, pools, water tanks, tunnels, bridge decks and industrial facilities.

Two types:

Single-component polyurea — Moisture-curing polyurea applied by brush, roller or trowel; cures within hours with no special spray equipment. The practical choice for retrofit projects, repairs, small and medium areas, and detail work where spray equipment is not available.

Two-component polyurea (spray) — High-pressure spray-applied polyurea with A and B components mixed at the gun, curing (gelling) in seconds and reaching full cure within 24 hours. Delivers maximum mechanical strength, elasticity and throughput for large-area projects with tight schedules.

✅ Cures in seconds (two-component spray) — surfaces return to service the same day
✅ Seamless membrane — no laps, no joints, no weak points
✅ Excellent adhesion to concrete, mortar and metal substrates
✅ High elasticity — elongation ≥ 300%, bridges structural cracks and thermal movement
✅ Strong mechanical performance — tensile strength ≥ 10 MPa
✅ Outstanding chemical, abrasion and impact resistance
✅ CE & ISO certified — meet standard
✅ OEM/ODM available — custom label, specification, color and packaging

FAQ

Q: What is a polyurea waterproof coating?
A: Polyurea waterproof coating is a liquid-applied elastomeric coating that cures in place to form a seamless, fully bonded waterproofing membrane. It is used for roofs, pools, water tanks, tunnels and industrial facilities, offering extremely fast curing, high elasticity and outstanding chemical resistance.

Q: What is the difference between single-component and two-component polyurea?
A: Single-component polyurea is moisture-curing and applied by brush, roller or trowel — the practical choice for retrofit, repairs and smaller areas without spray equipment. Two-component polyurea is high-pressure spray-applied, cures in seconds and delivers maximum mechanical strength and throughput for large-area projects with tight schedules.

Q: How fast does two-component polyurea cure?
A: The A and B components react at the spray gun and the material gels within seconds, reaching full cure within 24 hours — surfaces can typically return to service the same day.

Q: How is the coating applied?
A: Two-component polyurea is applied with high-pressure spray equipment. Single-component polyurea is applied by brush, roller or trowel. The substrate is cleaned and prepared before application.

Q: What are the key physical properties?
A: Tensile strength ≥ 15 MPa, elongation at break ≥ 300%, low-temperature flexibility down to -40°C and impermeability at 0.4 MPa × 2h (two-component spray type).

Q: Is polyurea suitable for pools and water-contact structures?
A: Yes. The seamless membrane with no laps or joints, combined with excellent chemical resistance, makes polyurea a preferred system for swimming pools, water parks, water tanks and reservoirs.

Q: What is the minimum order quantity?
A: MOQ is 1290 KG.

Q: Can you do OEM / private label?
A: Yes — custom thickness, width, surface and brand labeling.

Q: What is the lead time?
A: 15–25 days after order confirmation.

Q: Do you provide samples?
A: Yes, samples available before bulk order.

Q: What certifications do you have?
A: CE, ISO 9001/14001/45001, CEC Green Label.
