 | Fast setting, deep crystallizing mineral surface coating which is resistant against pressurized water. It is suitable for the fast positive or negative side waterproofing of masonry and concrete, e.g. in basements or water tanks. |
 | Ready-mixed liquid for KÖSTER NB sealing slurries. The latex based dispersion KÖSTER NB 1 Flex has a plastifying effect, improves the adhesion to the substrate and prevents the premature drying out of the fresh slurry. |
 | Watertight (> 130 m water head) 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.
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.

 | For abrasion resistant waterproofing of concrete and masronry structures which are in danger of cracking. KÖSTER NB Elastic Grey is a 2-component system, bridges cracks up to 2 mm and is resistant to pressurized water. It is suitable for the waterproofing of balconies, terraces and crack bridging waterproofing of concrete elements, also under tiles. Radonproof. |
 | For abrasion resistant waterproofing of visible concrete and masronry structures which are in danger of cracking. KÖSTER NB Elastic White is a white, 2-component system, bridges cracks up to 2 mm and is resistant to pressurized water. It is suitable for the waterproofing of balconies, terraces and the crack bridging waterproofing of concrete elements, also under tiles. Radonproof. |
 | 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. |
 | KÖSTER Elastic Roof is an elastic, crack bridging, and solventfree waterproofing material for dry and slightly damp substrates. It is free of VOCs (Volatile Organic Compounds), free of Polyurethanes, and free of Isocyanates. The fast drying foil-like coating is highly flexible, watertight and water vapor permeable. The foil is resistant against ageing, hydrolysis, UV-rays, frost and de-icing salts. The white color reflects heat. Since KÖSTER Elastic Roof sticks to itself, the application is easy and seamless. |
 | Very thin fluid, deeply penetrating silicifying concentrate for waterproofing against rising damp (wicking moisture) in masonry. It reacts to water insoluble and water-repelling compounds which also have a solidifying effect on the building material. Together with KÖSTER Restoration Plasters it is suitable for the restoration of masonry. |
 | Silicifying concentrate in ready to use cartridges for waterproofing against rising damp (wicking moisture) in masonry. For pressureless injection into masonry. Together with KÖSTER Restoration Plasters it is suitable for the restoration of masonry. |
 | Sulphate-resistant, solidifying mortar with silicifying properties for the filling of voids and cracks during the installation of a horizontal barrier. Due to the low viscosity the mortar penetrates into the finest voids and cracks. Capable of flowing. In particular for use before the installation of horizontal barriers by pressurized injection. |
 | Can be applied in strongly moisture penetrated construction members for waterproofing against rising damp (wicking moisture) without previous drying. The material is applied by pressurized injection. Together with KÖSTER Restoration Plasters it is suitable for the restoration of masonry.
KÖSTER Mautrol® 2C is a two-component, solvent-free, low viscous injection fluid on the basis of siliconates and esters and has a solidifying effect on mansonry. |
 | 2-component, solvent-free, water dilutable acrylic based injection liquid against rising damp (wicking moisture). Suitable for application even in very damp construction members without drying them beforehand. |
 | Very low viscosity synthetic resin for waterproofing against rising damp (wicking moisture) even in case of high moisture and salt contents in the masonry. Due to its very low density and its surface tension which is considerably lower than that of water, KÖSTER Crisin 76 displaces water from the capillaries. After full cure, KÖSTER Crisin 76 remains elastic and does not rot. Density: 0.76 g/cm³, viscosity 1.2 mPa · s. KÖSTER Crisin 76 is resistant to all aggressive media which are usually encountered in masonry such as acids, alkalis and salts, during application as well as after full cure. Tested according to WTA guidelines. Together with KÖSTER Restoration Plasters it is suitable for the restoration of masonry.
