Product Description
An elastomeric resin and polymer-based, one-component, super-elastic, ready-to-use, UV-resistant waterproofing material.
Application Areas
- On precast surfaces and exterior facades
- Water tanks, swimming and ornamental pools
- On sloped terrace roofs
- Wet areas such as bathrooms, WCs and balconies
- On the exterior facades of silos and buildings
- Used as an elastic waterproofing material on reinforced concrete, galvanised sheet, polyurethane foam, zinc, PVC eaves and concealed gutter surfaces.
Advantages
- Owing to its high flexibility at low temperatures, it offers high long-term resistance to cracking.
- Resistant to hail impact (important for terraces).
- Provides very good adhesion even on difficult surfaces.
- Provides very good protection against carbonation.
- Resistant to the passage of ponding water. UV-resistant.
- Applied directly by brush or roller.
- Can be painted over and covered with ceramic tiles.
Application
Before FLEX AST is applied, new hot asphalt surfaces must have cured for at least 14 days and new concrete surfaces for at least 28 days. Mortar residues on the cured surface are removed by light sandblasting or brushing, after which the selected primer is applied. Loose particles such as old paint, dirt and dust on old concrete and cement plaster surfaces are removed by sandblasting, scraping and brushing. Oil and grease residues are cleaned with water and detergent; if neutralisation is required, the surface is wiped with a 3-4% hydrochloric acid or acetic acid solution and washed with pressurised water. Before FLEX AST is applied, care must be taken that the substrate is completely dry. The court surface is wetted with water and left to dry. During drying, water collects in low-lying areas.
