Surface preparation:Prepare the substrate in accordance with SP 71.13 330.2017.
- Clean the substrate of dust and dirt. Remove any weak layers of old paint and limewash from previously painted surfaces.
- Sand solid, firmly adhering glossy surfaces to a matte finish; remove sanding dust.
- Level out unevenness, pits, cracks, and chips with the water-dispersive putty Bergauf UNI PASTA, then sand.
- Surfaces previously coated with chalk or lime paints must be thoroughly cleaned until completely removed. Intensely absorbent surfaces should be pre-primed in advance to improve the reliability of the coating and reduce paint consumption.
- Bergauf Techno Primer primer is recommended, as well as putties.
- The surface to be painted must be dry and clean; the base temperature for carrying out work is from +5°C, the room temperature during paint application is from +5°C to +35°C, and the 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. Stir with a wide, flat slat or a construction mixer at low speeds, carefully, not allowing the formation of air bubbles, for 1−3 minutes. It is not recommended to stir the material by shaking a closed can. After transportation and/or intensive stirring, if air bubbles occur, the paint needs to stand until they disappear. Apply the paint to the prepared, dry, clean surface using a brush, roller or paint sprayer. For rough surfaces such as textured plaster, brick, concrete blocks, embossed ceilings, it is recommended to use rollers with a 12−25 mm pile length. For rough surfaces such as putties, plaster, concrete, fiberglass fabric — with an 8−12 mm pile length. For smooth surfaces such as plasterboard, MDF, chipboard, architectural décor elements (trim pieces, moldings, ceiling cornices) — with a pile length of up to 6 mm.
The paint is ready to use; for application with a brush or roller, if necessary you may dilute it with water by no more than 5%. 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 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. When carrying out the work, avoid exposure to direct sunlight and conditions of high humidity. After finishing, wash hands and tools thoroughly with warm water.
