Surface preparation:Surface preparation should be carried out in accordance with SP 71.13330.2017.
- Clean the base of dust and dirt. From previously painted surfaces, remove loose layers of old paint and whitewash.
- Sand hard and firmly adhering glossy surfaces to a matte finish, and remove sanding dust.
- 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. Intensely absorbent surfaces should be pre-primed with Bergauf Techno Primer deep-penetrating primer to increase the reliability of the coating and reduce paint consumption.
Work procedure: The surface to be painted must be dry and clean, the base temperature for work must be from +5°C, the room temperature during paint application must be from +5°C to +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 layer.
Stir the paint thoroughly. It must be stirred with a wide, flat stick or a construction mixer at low speed, carefully, avoiding the formation of air bubbles, for 1–3 minutes. Do not
recommend stirring 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 a prepared, dry, clean surface with a brush, roller, or spray gun. For rough surfaces, such as textured plaster, brick, concrete blocks, embossed ceilings, it is recommended to use rollers with a pile length of 12-25 mm. For
rough surfaces, such as putty, plaster, concrete, paintable wallpaper, fiberglass, and non-woven wallpaper — with a pile length of 8–12 mm. For smooth surfaces, such as drywall, MDF, chipboard, and architectural decor elements (architraves, moldings, ceiling cornices) — with a pile length of up to 6 mm. The paint is ready to 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 permitted, using a 0.013–0.015″ nozzle at a pressure of 180–190 bar. The spray angle should be 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, two coats of paint must be applied.
When carrying out work, avoid exposure to direct sunlight and conditions of high humidity.
After finishing work, wash hands and tools thoroughly with warm water.
Safety precautionsWork should be carried out using personal protective equipment for hands, eyes, and respiratory tract. Use in well-ventilated areas.
