Surface preparation:Substrate preparation should be carried out in accordance with SP 71.13330.2017.
- Clean the substrate from dust and dirt. Remove unstable layers of old paint and whitewash from previously painted surfaces.
- Hard and firmly adhering glossy surfaces should be sanded to a matte state, and sanding dust must be removed.
- Level out irregularities, depressions, cracks, and chips with Bergauf UNI PASTA water-dispersion putty, then sand.
- Surfaces previously covered with chalk or lime paints must be thoroughly cleaned until completely removed. Intensively absorbing surfaces should be pre-primed with Bergauf Techno Primer deep penetration primer to increase coating reliability and reduce paint consumption.
The surface to be painted must be dry and clean; the substrate temperature for the work must be at least +10°C, the room temperature during paint application must be between +10°C and +35°C, and the relative air humidity must be below 80%.
It is recommended to use paint from the same production batch to avoid differences in the shade of the finish coat.
Stir the paint thoroughly. Stirring should be done with a wide, flat slat or a construction mixer at low speeds, carefully, avoiding the formation of air bubbles, for 1–3 minutes. It is not recommended to mix the material by shaking the closed can. After transportation and/or active stirring, if air bubbles appear, the paint needs to settle until they disappear.
Apply the paint to the prepared dry clean surface with a brush, roller, or spray gun. For rough surfaces such as textured plasters, brick, concrete blocks, and relief ceilings, it is recommended to use rollers with a pile length of 12−25 mm. For
rough surfaces such as putties, plasters, and concrete — with a pile length of 8–12 mm. For smooth surfaces such as gypsum board, MDF, chipboard, and architectural decor elements (architraves, moldings, ceiling cornices) — with a pile length of up to 6 mm. The paint is ready for use; for
application by brush or roller, it can be diluted with water by no more than 5% if necessary. For airless spraying, dilution with water by 5–10% is allowed, nozzle size 0.013–0.015″, pressure 180–190 bar. The spray angle is chosen based on the area and geometric features of the surface being painted.
To obtain a rich color and improve the appearance of the surface, it is necessary to apply two coats of paint.
Avoid exposure to direct sunlight and high humidity conditions during work.
After completing the work, wash hands and tools thoroughly with warm water.
Work should be performed using personal protective equipment for hands, eyes, and respiratory tract. Use in well-ventilated areas.
