Product Usage
Mix liquid A with powder B as supplied, brush/roll/spray 1.5-2.0mm thick in 2-3 coats for roofs, basements, or pools.
Prep clean surface, mix to smooth paste, apply first coat wet-on-wet, cure touch-dry 4h at 25°C, full 7 days.
Contractors stick with it for strong wet bonds and flex that lasts through weather shifts.
