Micro-reinforced mineral-based powder product for thin-layered leveling of exterior walls. Used for manual application up to a maximum thickness of 5 mm.


The substrate to which BK-GletEx S is applied, must be solid, clean and dry, without loosely bonded parts, grease stains, etc. In case of application to high-quality mineral surfaces as well as to well-absorbed dispersion paints, the substrate must be previously coated with BK-Podloga in order to achieve better adhesion of the skim coat. In case of highly absorbent surfaces, impregnation with BK-Nivelator can be performed. In case of peeled off, worn and/or dusty surfaces, all loosely bonded layers must be removed and then impregnated with BK-Penetrat. The preparation of the compound is done by adding the powder in about 40% of water (2 l of water for 5 kg of product, 10 l of water for 25 kg of product) to achieve a homogeneous mixture, without lumps. Allow the mixture to rest for 10 minutes and stir once more before application. The compound is usually applied in two layers, by hand, with a metal trowel, with a total thickness of up to 5 mm. The second layer is applied after complete drying of the first one, and after each layer the possible folds should be processed with sandpaper, with grain size 80-180 depending on the technique and purpose. See product datasheet for more detailed instructions.
