ReadMulti-Layer Waterproofing Systems
A fibre reinforced, elastomeric polyurethane waterproof system in 7 integrated layers, with elongation above 500% and 3000+ hours of weathering to ASTM G-154.
High Performance Fibre reinforced Polyurethane Advanced Technology Elastomeric waterproof system. Complies with ASTM G-154.
Figures are controlled laboratory results. Actual site performance varies with substrate, temperature, humidity, application method and workmanship — please confirm the current product datasheet before specification.
RAINCARE PUA 7 Layer System is a 7 layer polyurethane waterproofing system that is fibre reinforced and elastomeric. It is built up on site in 7 integrated layers: a PU primer, 3 base coats with mesh reinforcement, an intermediate protective coat and a UV-resistant topcoat in 2 passes. It is meant for critical infrastructure waterproofing where long service is expected.
Seven reinforced PU layers for facilities that must stay dry.
UV-resistant topcoat suits surfaces left open to the weather.
Applied as a full 7 layer system over the PU primer.
Three mesh reinforced base coats form the body of the system.
Stated service life of 15+ years suits long-term projects.
For critical facility roof leakage, the figures are elongation above 500%, 3000+ hours of weathering under ASTM G-154 and a stated service life of 15+ years. This advanced PU waterproofing goes down as a PU primer, 3 base coats with mesh reinforcement, an intermediate protective coat and a UV-resistant topcoat in 2 passes. Allow 14 days for the full system to cure.
Armstrong Chemicals supplies RAINCARE PUA 7 Layer System to sites across Telangana, Andhra Pradesh, Karnataka, Kerala and Tamil Nadu, including Hyderabad, Vijayawada, Bengaluru, Kochi and Chennai.
Elongation above 500% lets the cured membrane stretch with the structure, so movement is less likely to split it.
It is rated for 3000+ hours of weathering under ASTM G-154, and the topcoat is UV-resistant.
Three base coats carry mesh reinforcement, which gives the 7 layer build its fibre reinforced body.
