Description
Fast-Curing Polyurea Waterproofing System for High-Demand Applications
Neoproof® Polyurea R is a cold-applied, two-component elastomeric polyurea waterproofing coating developed for long-term protection of exposed roofs and other demanding construction surfaces. It is formulated to deliver exceptional mechanical strength, rapid curing performance, and superior waterproofing reliability under harsh environmental conditions.
The system cures to form a seamless, blister-free membrane that is completely resistant to moisture penetration, with zero water absorption and excellent resistance to UV radiation and mechanical stress.
At Everkast, this system is recommended for projects where speed of return to service, durability, and high-performance waterproofing are critical — particularly in Nigerian environments characterized by heavy rainfall, high solar exposure, and thermal movement.
One of its key advantages is its fast resistance to early rain, achieving initial resistance within approximately one hour after application, making it ideal for time-sensitive or fast-track projects.
Neoproof® Polyurea R is classified in the highest performance category (W3) under EAD 030350-00-0402, with an expected service life of up to 25 years under severe climate conditions and across all roof slope categories.
The coating maintains its elasticity across a wide temperature range and exhibits excellent crack-bridging performance, ensuring long-term protection even on substrates subject to movement or structural stress.
