Surface preparation:Prepare the substrate in accordance with SP 71.13330.2017.
- Clean the substrate from dust and dirt. Remove loose layers of old paint and whitewash from previously painted surfaces.
- Hard and firmly adhering glossy surfaces should be sanded to a matte state, and sanding dust must be removed.
- Surfaces previously covered with chalk or lime paints must be thoroughly cleaned until completely removed.
- Intensively absorbing surfaces should be pre-primed with Bergauf Techno Primer deep penetration primer to increase the reliability of the coating and reduce the consumption of the primer-paint.
Work procedure: The surface to be painted must be dry and clean, the substrate temperature for performing work from +5°C, the room temperature during paint application from +5°C to +35°C, and relative air humidity below 80%.
It is recommended to use primer-paint from the same production batch to avoid differences in shade.
Mix the primer-paint thoroughly. It is necessary to mix with a wide and flat slat or a construction mixer at low speeds, 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 primer-paint needs to settle until they disappear.
Apply the primer-paint to the prepared dry, clean surface using a brush, roller, or paint sprayer.
For rough surfaces such as textured plasters, brick, concrete blocks, and relief ceilings, it is recommended to use rollers with a pile length of 12−25 mm. For coarse surfaces such as putties, plasters, concrete, fiberglass, and painting non-woven wallpaper — with a pile length
of 8−12 mm. For smooth surfaces such as gypsum board, MDF, chipboard, architectural decor elements (architraves, moldings, ceiling cornices) — with a pile length of up to 6 mm.
The primer-paint is ready for use. For airless spraying, dilution with water by 5−10% is allowed.
When carrying out work, avoid exposure to direct sunlight and high humidity conditions.
Upon completion of work, wash hands and tools thoroughly with warm water.
Safety precautionsWork should be performed using personal protective equipment for hands, eyes, and respiratory tract. Use in well-ventilated areas.
