Universal microfiber structural primer designed to provide uniformity, neutralization, hardening and waterproofing of the substrate before applying all types of facade paints and decorative renders, except silicate paints/renders. It is suitable for filling fine cracks and further reinforcing the substrate. It is most commonly used in combination with BK-MicroFas Acryl and BK-MicroFas Silicon.


The substrate to which BK-MicroGrund Universal is applied must be solid, clean, dry, and free of oil. BK-MicroGrund Universal primer should be mixed and diluted with 10-15% of water (0.8-1.2l of water for 8kg of product, 2.5-3.75l of water for 25 kg of product) before use. Apply the diluted primer to the wall with a long-air roller in two coats, with crossed movements. Drying time between applications should be min. 4h. It is necessary to work evenly with the “full roller” so that the coated surface is crossed by the roller several times in different directions to avoid grouping the filler in one place. The time required for drying until applying the finishing coat is 24 hours. See the product datasheet for more detailed instructions.
