One-component, waterproofing coating for horizontal and vertical protection of surfaces from moisture. It is used for waterproofing potentially damp rooms: kitchen, bathrooms, shower cabins, swimming pools, basements, terraces, etc. It is intended for indoor and outdoor use and is not intended for surface finishing, nor for systems that are in permanent contact with water.


The substrate on which BK-HidroStop Base is applied must be firm, dust-free, dry and free of grease, mold and loose parts. Before applying the waterproofing, it is recommended to coat the BK-Ultra Prime substrate. In the case of old and unevenly absorbing substrates, as well as in the case of porous highly absorbent substrates, it is necessary to apply BK-Ultra Prime, min. 4h before applying the waterproofing. In the case of surfaces that peel, wear and / or dust, it is necessary to remove all loose bonds and then impregnate the substrate with BK-Penetrat. It is necessary to wash the concrete surfaces well with hot water in order to remove the present impurities and then, after complete drying, coat them with BK-Beton Kontakt.

The coating is prepared by adding about 5.5 l of water to a 20 kg bag, mixing until complete homogenization. Leave the mass to stand for about 5 minutes and mix again. Use the prepared mass within 2 h. The coating is applied with a brush in two coats, crosswise, until the surface is completely covered. The thickness of one layer is approximately 1 mm, and the other layer is applied after the previous one has hardened. The waterproofing coating should be protected from rapid drying. After 12 hours from the application of the last layer, the surface is ready for laying ceramics (for gluing use adhesives SiproFix BK-110 ). See the product data sheet for detailed instructions.
