1. rough room wall paint

The wall decoration of the rough house generally determines how to decorate according to the function of the space. The wall and ceiling of the living room and bedroom can choose to paint the wall, bathroom, kitchen, balcony and other spaces. Because of the more water vapor, it can only be painted on the ceiling. The actual utilization rate of the house is about 80% of the building area, while the kitchen and bathroom are mostly made of ceramic tiles and gussets. The area of ​​these two spaces is generally about 10 square meters.

Therefore, if all the walls of the home are painted, the wall construction area can be calculated as follows: wall paint construction area = (building area × 80% - 10) × 3. For example, if the building area is 88 square meters, the construction area = (88 × 80% - 10) × 3 = 181.2 square meters. The construction of the wall paint is two sides (one primer, two top coats). The amount of wall coating is generally calculated according to one kilogram of latex paint (or primer), which can be used to brush 10 square meters of wall surface. After conversion, 1/10 kg of wall paint is required per square meter of wall surface. Primer dosage = construction area × 1/10; top paint consumption = construction area × 2 × 1/10.

If the wall renovation area is large and there is a crack in the skin, it is recommended to shovel and repaint.

The construction area = the inner area of ​​the sleeve × 2.5 (or × 3), the door and window can be more than × 2.5, anyway, × 3. However, there are certain discrepancies in the calculation results of this method.
