Mineral thin-layer decorative render on lime-cement substrate, intended for protection and decoration of exterior facade surfaces.
RENDER STRUCTURE AND GRAIN SIZE
BK-Briv Special – scratched structure, reib, rille (grain size 1. 5 and 2 mm); BK-Briv Special – full structure, full, kratz (grain size 1, 1. 5 and 2 mm).
PREPARATION AND APPLICATION
The surface to which render is applied must be solid, clean and dry, with no loose parts, free of oil stains and similar. Before applying the render, the substrate must be coated with BK-Grund Universal. In the case of highly absorbent substrates, coating with BK-Nivelator is recommended, while in the case of weak and scaling substrates the surface must be coated with BK-Penetratbefore applying the render. Preparation is performed by adding the powder to about 24-26% of water (6-6.5 l of water for 25 kg of product) while stirring vigorously until complete homogenization; leave the mass to rest for 10 min, then stir once more. The render is applied with a steel trowel with thickness of the largest grain. Depending on the desired structure, the render is then processed with a plastic trowel, namely: Full (full-kratz) structure – structured in a circular pattern immediately after application, Reib (scratched-rille) structure – after application scratch by circular motions until the desired structure is achieved. See product datasheet for more detailed instructions.
From +5°C to +30°C. Do not work under direct sunlight, rain or strong wind.
Approx. 2. 5-3. 5 kg/m², depending on the desired structure and grain size of the substrate.
