High-performance elastomer coating for harsh environments requiring long-term protection. Moisture-cures to form a polymer elastomer. Offers excellent waterproofing, corrosion resistance, and wear resistance.

KEY ADVANTAGES OF POLYUREA WATERPROOF COATING

Extremely Fast Curing and High Efficiency

Polyurea coatings cure within seconds after application, allowing rapid return to service and minimizing project downtime. This fast-curing property enables multiple coats to be applied in a single day and makes the coating ideal for projects with tight schedules. Foot traffic and even vehicular access can often be permitted within hours of application.

CORROSION AND ABRASION RESISTANCE OF POLYUREA WATERPROOF COATING

Superior Corrosion Resistance

Polyurea waterproof coating demonstrates exceptional chemical stability, providing robust protection against a wide range of corrosive substances, including acids, alkalis, salts, and various industrial effluents. This inherent resistance makes it an ideal lining solution for demanding environments such as chemical plant floors, secondary containment areas, and wastewater treatment tanks. By forming an impermeable barrier, it effectively prevents substrate degradation and structural damage caused by chemical exposure, ensuring long-term durability in harsh industrial settings.

KEY INSTALLATION CONSIDERATIONS FOR POLYUREA WATERPROOF COATING

Polyurea application demands specialized spray equipment operated by trained professionals. Proper substrate preparation is critical—surfaces must be clean, dry, and typically abrasive-blasted to achieve the required anchor profile. Environmental conditions like temperature and humidity significantly affect curing and must be closely monitored. Precise control of mixed material ratios is essential for consistent performance. Due to the extremely fast cure time, application is a continuous process requiring careful planning. Safety precautions, including proper ventilation and full protective gear, are mandatory during spraying.
