Friends who have renovated the house know that wall acceptance is one of the most important aspects of home improvement acceptance. When checking, you must check it carefully. Otherwise, you will find the problem after you check in, which will bring a lot of trouble to your daily life. . Whether the effect of wall painting is fine, not falling off, and not mildew depends on the quality of the coating and the technical level of construction, especially the detailed treatment technology of the wall base. Therefore, the acceptance of the wall paint starts from the grassroots level, and should be checked and accepted once it has not been painted.
Acceptance of the base layer of the wall: The treatment of the base layer is the key link to ensure the quality of the construction. It is the most basic condition to ensure that the wall is completely dry, because the mortar paste of the cement as the bonding material is strongly alkaline before being hardened. Brush latex paint must be anti-alkali. When the cement mortar is hardened, the alkaline value is greatly reduced, and the latex paint can be applied at this time. Drying time varies depending on climatic conditions and should generally be placed for more than 10 days. The wall surface must be flat. At least the putty should be scraped twice. If it still fails to meet the standard, it should be scraped to meet the standard requirements.
Acceptance of wall paint film: The type and color of the paint used for latex paint are consistent. It is not allowed to have quality defects such as through the ground, leaking brush, falling powder, skin alkali, peeling and biting. When spraying with a spray gun, the spray point is evenly distributed, and no skin phenomenon is allowed. No drop is allowed. The hand touches the paint film smoothly, does not drop the powder, keeps the doors and windows, lamps, furniture, etc. clean, no paint marks.
Acceptance criteria:
1. Should stand at 1.5 meters from the wall, no blisters, bite, flow, color, and bottom.
2, should be evenly painted, the mucous membrane is firm, not leaking, through the bottom, peeling, and rust.
Paint surface quality inspection inspection method inspection standard
The large face is observed at a distance of 1.5 meters from the wall, without blisters, biting, falling, chromatic aberration, and through the bottom. It is not allowed to have a bottom surface, and the surface of the wrinkle should be bright and uniform, smooth and unobstructed.
The color of the brush is smooth; the high-grade color is consistent, the brush-free mixed color paint should be applied after the actual drying, and the deviation can be measured with a steel ruler with an accuracy of 1 mm, and the color separation line is at a length of 5 meters. Internal inspection. The bottom surface of the flow has no large surface wrinkles, the small surface has no obvious; flat and smooth and uniform; no large surface separation, the deviation of the small surface is not more than 2 mm: the color is consistent, the brush pattern is smooth; no leakage brush is allowed. Peeling and rusting.
The water emulsion coating inspection shall be carried out by visual inspection and hand feeling under natural light after the paint is dried. The wall and top surface must be flat, no powder, no wrinkles, no brush leakage, no obvious color difference, efflorescence, color return and brushing on the large surface, no obvious blisters, falling, creping and splashing.
