Surface preparation:Prepare the substrate in accordance with SP 71.13330.2017.
- Clean the substrate of dust and dirt. Remove loose layers of old paint and limewash from previously painted surfaces.
- Sand solid, firmly adhering glossy surfaces until matte, then remove sanding dust.
- Level out unevenness, pits, cracks, and chips with water-dispersive putty Bergauf UNI PASTA, then sand.
- Surfaces previously coated with chalk or lime paints must be thoroughly cleaned until completely removed. Highly absorbent surfaces should be pre-primed to improve coating reliability and reduce paint consumption.
- It is recommended to use Techno Primer primer as well as putties.
Work procedure:- The surface to be painted must be dry and clean. The substrate temperature for carrying out the work is from +5°C. The room temperature during paint application is from +5°C to +35°C. Relative air humidity is below 80%.
- The paint should not be mixed with organic solvents.
- It is recommended to use paint from a single production batch to prevent differences in the shade of the finishing coat.
Stir the paint thoroughly. Mixing should be done with a wide, flat strip or with a construction mixer at low speeds, carefully, without allowing air bubbles to form, for 1–3 minutes. It is not recommended to mix the material by shaking a closed can. After transportation and/or active stirring, if air bubbles appear, the paint needs to stand until they disappear.
Apply the paint to the prepared, dry, clean surface with a brush, roller, or paint sprayer. For rough surfaces such as textured plasters, brick, concrete blocks, and embossed ceilings, it is recommended to use rollers with a pile length of 12–25 mm. For rough surfaces such as putties, plaster, concrete, glass fabric (fiberglass scrim), paint nonwoven fabric—use a pile length of 8–12 mm. For smooth surfaces such as drywall, MDF, chipboard, and elements of architectural decoration (trim boards, moldings, ceiling cornices)—use a pile length of up to 6 mm. The paint is ready to use; if necessary, it may be diluted with water by no more than 5% for application with a brush or roller.
For airless spraying, dilution with water of 5–10% is permitted; nozzle 0.013–0.015″; pressure 180–190 bar. The spray angle is selected based on the area and the geometrical features of the surface being coated. To obtain a rich color and improve the appearance of the surface, apply two coats of paint. During work, avoid exposure to direct sunlight and conditions of increased humidity.
After finishing, wash hands and tools thoroughly with warm water.
