The wall as the bulk of home improvement, its quality directly affects the entire home's "value". So it's necessary to do a good job.
Paint acceptance1, the wall surface perception; check the wall there is no color, cracking, there are some peeling, through the bottom, or say some of the quality of rust such problems, there are these issues on the perception of the need to arrange for rectification.
2, the verticality and flatness of the wall; first use the yin and yang square to detect the squareness of all yin and yang angles, according to national requirements, the deviation of yin and yang angle can not exceed 3 mm. Second, use 2 meters on the ruler and feeler to check the flatness and level of the wall surface, the national standard requirement is that the deviation can not exceed 3 mm.
3, smallpox wall inspection; ceiling inspection, pay attention to whether there is cracking cracks, if the cracking, post-renovation must be scraped along the seam 5 cm to shovel the bottom out of all, shovel off the bandage or cloth after some reinforcement Measures.
4, empty phenomenon inspection; check the wall, use a reverberation drum hammer knock, listen to the sound to see if there is empty drum. If there is an empty drum, there may be a risk that the overall surface will fall off or crack.
Wallpaper acceptance1. Appearance check; pay attention to whether the entire wallpaper is contaminated or moldy. The problems that are easily caused by wallpaper include: peeling, floating, foreign matter, deformation, cracks, etc., which can be repaired according to actual conditions.
2, parquet acceptance; wallpaper and wallpaper in the intersection of the interface position, the parquet must be aligned. Within three meters, you cannot see a clear mosaic.
3, paving processing inspection; wallpaper transfer position can not be placed near the corner, as well as in the intersection with other cloth products must be very neat, wallpaper can not be exposed or to cover the socket, glue can not contaminate other parts.
4, hollow inspection; wallpaper paste firmly, the same color surface, no air bubbles, hollowing, cracks, Alice, wrinkles and stains, no squinting glue marks.
Brick surface acceptance1, the appearance of the inspection; the surface of the wall tiles missing corners off the case of porcelain. There are stains on the surface of the tiles and need to be cleaned. This situation may be due to the quality of the tiles on the one hand, and construction problems on the other hand. Attention should be paid to the protection of finished products during the renovation. The seam angle of the tile is not a 45-degree angle, which is biased and affects the perceived quality.
2, whether the seam is neat; the middle of the tile has a difference in height, the cause of the two aspects, one aspect may be the surface roughness caused by the quality of the process when laying; the other is the quality of the brick, for example The bricks are upturned. The rectification must be replaced. The seams of the tiles appear jagged. This should be noted during construction. Use professional tools or go to the factory for processing to avoid such jaggies and affect our perception.
3, the wall surface roughness; with 2M on the ruler placed in a horizontal position, and then use the feeler plug in the tilted up place, from the feeler to the reading, in general, does not exceed the acceptance standard 2 mm range, normal.
4. Empty drum inspection; tap the wall with a banging drum to judge if there is empty drum. The percussive sound of the empty drum tile is crisp, and the sound of the empty tile is dull. The reason is that when the shop is covered, the water absorption of the tiles is not enough, or the proportion of the cement mortar is not reasonable, which results in the emptying of the wall tiles and the adhesion force is not enough.
