Universal 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 advisable to tint the BK-Grund Universal primer in the same shade as the finish.
PREPARATION AND APPLICATION
The substrate to which BK-Grund Universal is applied must be solid, clean, dry and free of oil. BK-Grund Universal primer should be mixed and diluted with 15-20 % of water (3.75-5 l of water for 35 kg of product) before use. Apply the diluted primer to the wall with a long-hair roller or brush, in one coat. If necessary, in case of old, highly absorbent surfaces, it is possible to apply the primer twice in 2-3 hours. The time required for drying until applying the finishing coat is 12 hours. See product datasheet for more detailed instructions.
From +5°C to +30°C. Do not work under direct sunlight, rain or strong wind.
Approximately 0. 2-0. 25 kg/m² depending on absorbency and roughness of the surface.
