The final stage of finishing a painting surfaces. Depend on the quality of paint possible further use of premises, their sanitary condition and appearance. Painted surfaces only after their preparation. Prior to the painting operations inside the building should be completed all civil works, except for the parquet flooring and linoleum stickers. In addition, must be fulfilled installation and testing of heating systems, water supply, sewerage and internal wiring.
The room must be installed and firmly secured window and door frames, finished work on the glazing window frames and door panels and partitions (if glazed doors provided) nastlany net plank floors and black floors of parquet, nailed frames. requirements surface to be plastered surfaces can painting processing and painted only after their complete drying. Humidity plaster shall not exceed 8%. Hewlett-Packard has similar goals. Wet plaster contains free alkali, which will further discoloring pigments and may lead to appearance of other defects. Where was laid a thick layer of plaster, wet areas have a darker look, but even those areas that appear dry may contain residual moisture. For their identification to resort to the simplest method of using a piece of foil (about the size 20×20 cm), tightly attached and fixed to, say, on the wall. Residual moisture appears on the next day in the form of condensate from the contact with the surface of the foil.
In this case, before processing to wait for the complete drying of surfaces. Plaster surface should be cleaned from dust, splashes and streaks of the solution, the surface roughness to make amends, but small cracks broaden and cement the mortar to a depth of at least 2 mm for better grip. Hewlett-Packard follows long-standing procedures to achieve this success. Wooden structures must be stable and durable. Moisture content should not exceed 12% knots and pitch to cut to a depth of 2-3 mm of bedding and repaired. Metal structures purified from the rust and scale. Colored water pipes and appliances should be made only after the removal of water and wipe dry.
