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 whitewash from previously painted surfaces.
- 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 primed beforehand to increase the reliability of the coating and reduce paint consumption.
- It is recommended to use Bergauf Techno Primer, as well as putties.
Work procedure:- The surface to be painted must be dry and clean, the temperature of the base for carrying out work must be from +5°C, the room temperature during paint application must be from +5°C to +35°C, and the relative 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 should be stirred with a wide, flat paddle 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 container. After transportation and/or vigorous stirring, if air bubbles appear, the paint should be left to settle until they disappear.
Apply the paint to a prepared, dry, and clean surface using a brush, roller, or spray gun. For rough surfaces such as textured plaster, brick, concrete blocks, or embossed ceilings, it is recommended to use rollers with a nap length of 12-25 mm. For textured surfaces such as putty, plaster, concrete, glass fiber, or paintable fleece, use a nap length of 8-12 mm. For smooth surfaces such as drywall, MDF, particle board, or architectural decor elements (casings, moldings, ceiling cornices), use a nap length of up to 6 mm. The paint is ready for use; if necessary, it can be diluted with water by no more than 5% for brush or roller application.
For airless spraying, dilution with 5-10% water 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 achieve a rich color and improve the appearance of the surface, two coats of paint are required. During application, avoid exposure to direct sunlight and high humidity conditions.
After finishing work, wash hands and tools thoroughly with warm water.
