Consumption: Approx. 4 – 6 kg/m²

Watertight mineral waterproofing with subsequently crystallizing agents. Suitable for positive side and negative side waterproofing. A waterproofing made of KÖSTER NB 1 Grey possesses excellent pressure and abrasion resistance, as well as chemical and sulphate resistance. Approved by the building authorities and tested in accordance with the potable water guidelines. For area waterproofing in new construction and restoration, e.g. waterproofing of basements and tanks.

Consumption: 2 – 4 kg/m²

A multi purpose waterproofing product with excellent adhesion to dry and moist substrates. KÖSTER 21 is a 2 component, solvent-free, liquid applied, elastic and crack bridging material. It is liquid applied and therefore seamless, which greatly eases application to complicated architectural details. Due to its UV stability it is suitable for indoor and outdoor use. The white color reflects sunlight and reduces building surface temperatures. The fast curing coating is highly flexible, resistant to occasional foot traffic, aging, hydrolysis, UV-rays, frost, and salt.

KÖSTER 21 seals against synthetic oils and aliphatic hydrocarbons with high boiling points (up to 2 bar). KÖSTER 21 is not resistant against substances with high aromatic hydrocarbon contents such as benzene, xylene, toluene, etc. In case of questions contact our technical support team. KÖSTER 21 does not contain volatile organic compounds (VOC content = 0), is free of polyurethanes, isocyanates, and bitumen.

 
Consumption: Approx. 2.2 – 2.6 kg / m²
