USE

Precious mineral thin-layer render on lime-cement basis, intended for all leveled substrates of lime-cement and cement mortars, for indoor use.

RENDER STRUCTURE AND GRAIN SIZE

Scratched structure, reib, rille ; full structure, full, kratz

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. Depending on the absorbency and the quality of the substrate, priming with BK-Grund Universal should be carried out if necessary. 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. Primer drying time before applying render should be at least12 h. Preparation is performed by adding about 24-26% of water (6-6.5 l of water for 25 kg of prodcut) while stirring vigorously until complete homogenization; leave the compound 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.
