Zero VOC, tin-free pigmented waterproofing system made with UV-resistant polyurethane-silicone technology
WaterProofSystemsWP.02
Specification item
Non-yellowing, monochromatic, highly elastic waterproof coating for floors or balconies with excellent performance (UV resistance, water stagnation, frequent foot traffic, low temperature resistance, chemical resistance to solvents). The Purain system allows damp or wet substrates to be waterproofed in extreme temperatures (0°C-45°C). Purain also has a faster rain resistance than traditional old-generation moisture-curing polyurethane waterproofing products.
Technical specifications
Application
The application cycle in 3 steps. The drawing shows each layer as it goes down.
Step 1 / 3
Primer and perimeter sealing
Apply an even coat of PURAIN PRIMER to the substrate (floors and vertical surfaces) using a wide brush or long-nap roller. Once dry, seal the perimeters and roof drains with PROJOINT (single-component polyurethane sealant).
Step 2 / 3
Glass-fibre fabric reinforcement
Coat the perimeters and roof drains with TFV 225 (225 g/m² fiberglass fabric), embedding them with PURAIN PRIMER. Then, fully saturate the pre-cut fabric over the entire surface with PURAIN PRIMER using a resin roller (6-8 mm nap), pressing it with a dry roller to eliminate any bubbles or creases.
Step 3 / 3
Two coats of coloured waterproofing
Once the primer has dried (at least 6 hours at >20°C), apply two even coats of PURAIN COLOR, allowing 6 hours between coats. Use a resin roller (6-8 mm nap) with a consumption rate of 0.300 kg/m² per coat.
