In the process of closing and inspecting the new house, the wall belongs to the key inspection part of the house inspection, and there are many items that need to be inspected. The quality of the wall has a great impact on the later decoration, if there is a problem with the wall, then it will cause a lot of trouble in the process of future decoration, which will not only affect the quality of the decoration, but also affect the aesthetics of the decoration, so be cautious in the acceptance process. What are the acceptance standards for the new house wall?
What are the acceptance criteria for the wall of the new house?
1. All exterior finishes, including the exterior finishes of balconies and rain covers, should be completed according to the design documents.
2. Public parts, public facilities, various pipelines (feeding, drainage, rainwater, heating, heat), electrical equipment (distribution boxes, cabinets, panels, sockets, switches, lamps), etc., should be completed according to the design documents, and various test items should be completed according to the regulations.
3. All kinds of pipelines should be accepted for water flow, pressure test, ball test and heating thermal commissioning.
4. Carry out water storage and water drenching tests for roofing projects.
5. If the prefabricated floor slab or cast-in-place slab roof is used in each room within the door, it should be leveled without plastering and putty, so as to achieve dense slab joints, no cracks, smooth and smooth rubbing, smooth surface, basic uniform color and luster, and straight line angles;
6. The floor of the room with waterproof requirements should be planned in strict accordance with the building requirements of the waterproof layer and the protective layer, and two water storage tests should be carried out during the acceptance to achieve no leakage.
7. The slope of floor drain and flooding meets the design requirements, so that there is no flooding, and the joint is tight and smooth, and there is no leakage.
What are the methods for accepting the wall of the new house
1. Detect the hollow drum on the wall and check whether there is a hollow drum on the wall, and there may be a hollow drum on the plastering wall and tile surface. Therefore, it is necessary to carefully observe and check the hollowing phenomenon of the wall, so as to avoid the occurrence of wall ash and tile falling off in future life. We can use a special steel needle hammer (10g) to pad a few layers of paper and then tap the wall. If the sound of hitting the wall is not real, then mark it and fill it with putty at a later stage.
2. Detection of water leakage on exterior walls. There are more rainy weather in summer, during this time, it is easy to find traces of wall peeling and water seepage, such as indoor wall or roof seepage, the key area is the partition wall of the bathroom, and after a long time, the water will slowly leak into the living room, bedroom and other walls, which is also one of the important reasons why many owners find that the bedroom wall is partially moldy and peeling after moving in for a period of time. To check the walls for water leaks, it is best to go before the house is handed over and the day after heavy rain. In particular, check whether there are water stains on the wall, especially in some gables, the top surface of the kitchen and bathroom, the exterior wall and other places, if there are water stains, it means that there is leakage.
3. Wall crack detection Wall cracks are relatively easy to detect, and when detecting wall cracks, we can detect cantilever structure walls such as house exterior walls, load-bearing walls, floor slabs, and balconies. Generally, it is important to check whether there are stress cracks between the load-bearing wall and the floor slab, and whether there is serious color difference in the color of the wall. The visual inspection of the wall generally must check whether the color of the wall is uniform and flat, and whether there are cracks.
4. Inspection skills for the quality of wall latex paint and the smoothness of the wall. When the surrounding light is low, illuminate with a high-power bulb (200 watts), as soon as the lamp is on, whether the wall and ceiling are flat or not will be immediately seen through the shadow of the light, if it is uneven, it is necessary to repaint putty, and if it is partially painted (repaired), it will be different from the original color of the wall. When checking the flatness of the wall, we need to use a two-meter ruler to lean the ruler against the wall to see how big the error between the wall and the ruler is. Under normal circumstances, the error does not exceed 3mm, which is in line with the national norms. If the flatness of the wall is very wrong, it will lead to the skew of the wall in the later stage, whether it is paving wall tiles or wallpaper, the effect will be very poor, and even affect the normal placement of furniture.
5. At present, the national standard requirements for wall flatness and verticality are measured by a 2-meter ruler, and the error should be within plus or minus 3mm, and the deviation value of the ordinary plastering wall is 4mm, and the deviation of the brick surface is 2mm. If the error is large, it will have a great impact on the aesthetics of the later decoration.
6. Wall putty waterproof inspectionWhen we check the waterproofness of wall putty, you can bring a bottle of water, splash the water on the wall, and touch it with your hands.
7. Poor quality of wall brushing and curing, peeling and peeling: the degree of brushing and curing is poor, and it can be erased by hand!
8. Check the verticality and horizontality, and use the vertical detection ruler to detect the verticality and horizontality of the wall. When detecting, the left side of the detection ruler is close to the measured surface, observe the pointer, the scale is the deviation value, the verticality deviation value of the plastering façade is generally 5mm, the allowable deviation of the brick surface is 2mm, the horizontal deviation value of the plastering wall is 4mm, and the deviation of the brick surface is 2mm. Note that the horizontal tube must be calibrated before measuring the level.
Wall acceptance is an important part of the inspection process of the new house, which not only determines the quality of the latex paint and putty project in the later stage, but also prevents the wall from cracking and falling off after the new house is moved in. There are many details to pay attention to in the process of closing the house, and you can inspect the house through a professional home inspector or a renovation company.
