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. Prime highly absorbent surfaces beforehand to increase coating reliability and reduce paint consumption.
- It is recommended to use Bergauf Techno Primer, as well as putties.
- 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%.
- The paint should not be mixed with organic solvents.
- It is recommended to use paint from the same production batch to avoid color variations in the finish layer.
Stir the paint thoroughly. It is necessary to stir with a wide, flat stick or a construction mixer at low speed, 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 mixing, 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, and embossed ceilings, it is recommended to use rollers with a pile length of 12–25 mm. For textured surfaces such as putty, plaster, concrete, glass fiber, and painter's fleece, use a pile length of 8–12 mm. For smooth surfaces such as drywall, MDF, chipboard, and architectural decor elements (architraves, moldings, ceiling cornices), use a pile length of up to 6 mm.
The paint is ready for use; for application with a 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 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 saturated color and improve the appearance of the surface, two coats of paint must be applied. During work, avoid exposure to direct sunlight and high humidity conditions. After finishing work, wash hands and tools thoroughly with warm water.
