KÖSTER 21 20kg
Koster 21
This fast-curing coating is highly flexible; the seamless membrane is resistant to occasional foot traffic, UV rays, salt and frost.
Koster 21 seals against synthetic oils and aliphatic hydrocarbons with high boiling points. Not suitable for aromatic hydrocarbons such as benzene, xylene, toluene, etc.
Uses of Koster 21
Koster 21 is used on the positive side for waterproofing:
- Basements
- Concrete slabs
- Tanks
- Flat roofs
- Terraces or balconies
Applying Koster 21
Koster 21 is applied in two coats, with drying time between coats depending on site conditions. On vertical surfaces, allow at least 3 hours before applying the next coat. On horizontal areas, allow 24 hours before light foot traffic. Areas prone to cracking or at wall/floor junctions should be reinforced by embedding Koster Flex Fabric into the first fresh layer. When used on roofs and balconies, the entire surface must be reinforced. Fresh coatings are water-soluble and must be protected from rain until fully dry.
