LP-Coat PUA 2000
2K Fast-Curing Pure Polyurea Elastomeric Protective Coating
Gel Time: 5 - 15 Seconds |
100% Solids / Zero VOC |
Standards: ISO 12944 / ASTM D412|
LP-Coat PUA 2000 is a premium, two-component 100% pure polyurea elastomeric coating designed for heavy-duty waterproofing, chemical secondary containment, and high-impact infrastructure protection. Engineered for high-pressure spray application, it sets within seconds to form a seamless, ultra-durable, and monolithic barrier with exceptional tear resistance and chemical immunity.
Key Performance Features
Ultra-Fast Curing & Rapid Return-to-Service
Gels in seconds and achieves walk-on capability within minutes, dramatically reducing project downtime for critical infrastructure.
100% Solids & Zero VOC Solvent-Free
Contains no solvents or VOCs, allowing high-build application in a single pass without shrinkage, bubbling, or pinhole defects.
Heavy Impact & Tear Resistance
Superior tensile strength (≥ 18 MPa) and high abrasion resistance protect substrates under severe mechanical stress and vehicular traffic.
Chemical & Corrosion Immunity
Provides exceptional resistance to acids, alkalis, salt spray, fuels, and industrial wastewater in harsh processing environments.

Application & Surface Prep Guide
Substrate Preparation & Abrasive Blasting
Concrete must be abrasive blasted/shot-blasted to remove laitance and achieve a CSP 3–5 profile. Steel surfaces must be blasted to Sa 2.5 standard.
Priming & Surface Sealing
Apply LeakProof Epoxy/PU Polyurea Primer to seal concrete moisture and pores, preventing pinholes. Scatter quartz sand if mechanical keying is required.
Plural-Component Spray Equipment Setup
Requires heated, high-pressure plural-component spray equipment (mixing ratio 1:1 by volume). Maintain pressure at 2,000 - 2,500 psi and pre-heat temperatures at 60℃ - 70℃.
Spray Application & Quality Control
Spray LP-Coat PUA 2000 continuously to the required thickness (typically 1.5 - 3.0 mm) in cross-hatch passes. Inspect pinholes using a high-voltage spark detector.
