Wall acceptance is one of the most important items for home improvement acceptance. Care must be taken when accepting it. Otherwise, people will find problems after they live, which can be very troublesome. The following is a detailed description of the acceptance points for wall painting.

Whether the effect of wall painting is fine, not falling off, and not mildew depends on the quality of the coating and the construction technology, especially the treatment technology of the wall base. Therefore, the acceptance of the wall paint surface starts from the base layer, and should be accepted once it has not been painted, and then accepted again after painting.

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.

The surface should be bright and uniform, smooth and unobstructed

The color of the brush is smooth; the advanced color is consistent, no brush

The mixed color paint should be applied to the visual inspection or hand feeling after it is dried. The allowable deviation is measured with a steel ruler with an accuracy of 1 mm, and the color separation line is checked within a length of 5 meters. Through the bottom \ flow falling \ no large face wrinkled skin, small face no obvious; flat \ smooth and uniform; no large face color separation wrap, small face allowable deviation is not more than 2 mm: the color is consistent, the brush pattern is smooth; not allowed Leakage, peeling, and rust.

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.
