Waterproofing Coatings — Liquid Systems for Concrete
Cold-applied liquid waterproofing: polyurethane, JS polymer-cement, acrylic elastomeric and crystalline coatings. Cold brushing, roller or airless spraying — no open flame on site, ideal for occupied buildings and complex details.
Coating Systems
Polyurethane (1K / 2K)
High-elongation seamless film for basements, bathrooms and flat roofs; solvent-free and waterborne options.
JS Polymer-Cement
Cement-based two-component coating — the cost-effective standard for kitchens, bathrooms and basements; paints over damp substrates.
Acrylic Elastomeric
UV-stable exposed-grade coating with reflective options for roofs and external walls.
Crystalline Waterproofing
Cementitious capillary-crystalline slurry and admixture for positive/negative-side treatment of concrete. Datasheet on request.
Non-Cured Rubberised Asphalt
Self-healing liquid membrane for underground works and detail flashing. Datasheet on request.
Application Guide
| Application Area | Recommended System | Typical Application |
|---|---|---|
| Basements & foundations | PU 2K / crystalline / non-cured asphalt | Cold brush or spray; trowel for details |
| Bathrooms & kitchens | JS polymer-cement | 2–3 coats brush applied, tileable |
| Exposed flat roofs | Acrylic elastomeric / PU | Roller or airless spray, reflective topcoat |
| Water tanks & pools | Cementitious / food-grade options | Brush applied, potable-water approvals on request |
