The supervisor must keep an eye on these 20 places.
0 1. Avoid using low-specification wires on high-power appliances.
Wire specifications The current wires are all single copper wires, with different specifications and much price difference. Sometimes decoration companies use low-standard wires to save costs. Home improvement sockets should be at least 4 square meters, switches should be 2.5 square meters, and kitchen power supply should be 6 square meters, otherwise the home will easily trip later.

02. The load-bearing wall cannot be slotted.
In hydropower construction, it is necessary to slot the wall and ground, and it is not recommended to slot the load-bearing wall. For the convenience of wiring, some workers randomly slot the insulation layer on the wall, which is easy to cause surface cracking. Generally, the groove is vertical, so it is recommended not to open horizontally, because it is equivalent to cutting off half of the wall, which makes the wall lose its original bearing capacity and brings certain security risks. If workers open a horizontal trough, they must stop it.
03. Is the wall material authentic?
The steps of powder brushing are: shoveling, basic treatment, plastering, hanging nylon net, putty, primer and topcoat. Because many decoration companies will use fake wall materials for construction, it is necessary to see if they are genuine before going to the wall to ensure the safety.
04, sewer protection work
Some owners just moved in and found that the sewer pipe in their home was blocked. This may be because they did not do a good job of protection during construction, resulting in cement, sand and other building materials entering the sewer.
Therefore, during the construction, we must see whether the workers have blocked the sewer pipe in advance.
05, don't shovel white
The top walls of many new houses have been painted by developers, but suggestions must be removed. In order to reduce costs, some decoration companies often do not directly eradicate the original white wall and repaint latex paint. After a long time, the shell will inevitably fall off before construction.
06. Cut corners on the ceiling keel system
For example, the specifications of suspenders generally require the use of screws that are not small 8mm, but in the actual ceiling process, 6mm suspenders are often used. So the ceiling is very weak. In addition, the wall thickness of the keel is very thin.
07, cut corners in the process of ceiling construction.
The first point is that the sling spacing is too large. The suspender spacing of light steel keel plasterboard ceiling is not more than1.2m. In the actual construction process, you will find that the suspender spacing in our house is very large. In addition, the number of main keels used is too small, which will be too weak, so be vigilant.
08, the bathroom waterproof height cut corners.
The waterproof of the bathroom shower area should be greater than 1.8MM, not less than this size, and at least 30 cm in other places, not less than these sizes. Some decoration companies deliberately only do things like 12M, and you don't know when they will finish tiling.
09, ground leveling
If you want to put tiles at home, you don't have to. If you want to lay the floor, you need to level it. But many workers don't level directly. The money is collected directly, because you don't know after the construction, and the floor is uneven in the later period.
10, gypsum line installation
During the installation process, use quick adhesive powder to paste. In order to save the cost of materials, some construction units will require construction workers to smear on the construction high line. This construction method is wrong. In order to ensure that the plaster line is firmly pasted, all plaster lines should be painted.
1 1, the bathroom floor drain is not inclined.
If you don't make a certain slope, you can probably soak your feet in the shower, because the water will have a certain impact. Try to wash it with a basin of water when you accept it, and rework it if you don't get into the water quickly.
12. Wire threading
If the workers operate carelessly, the wires may kink in the pipeline, causing hidden dangers of electricity consumption. Because the wires are hidden in PVC pipes, it is necessary to check them carefully, and some workers have great hidden dangers in the later stage in order to steal a pipe from the trade union, so they cannot agree.
13, slag backfilling
If the owner is not in the bathroom, workers can choose to use the construction waste to operate, which is simple and convenient, and saves the time of garbage disposal. The backfill of building dregs is excellent, which will destroy the waterproof layer after a long time. There are many shortcomings in the most scientific operation method of carbon slag backfilling and quarrying.
14, the original waterproof layer should be thoroughly cleaned.
Waterproofing of new houses is done by developers, but many developers are not qualified and need to be redone. Some construction workers cut corners and do secondary waterproofing on the original waterproof layer, which leads to the hollowing and falling of tiles in the later period. The correct way is to clean up all the original waterproof layers.
15, wall painting project
The prepared latex paint should be used up at one time, and the paint of the same color should also be brushed up at one time. This is to avoid the color difference on the wall, and irresponsible workers may paint it many times, which will lead to poor decorative effect.
16, single and double waterproof
However, many construction teams will choose to apply a single waterproof coating when the owner is away. You can't see any big problems when you collect it, and it's easy to leak after living for a long time. The best waterproof method is double-layer: coating waterproof and polypropylene waterproof double insurance, which is more secure.
17, the difference between the wall with and without steel wire mesh
Demolition and renovation are very particular. First of all, the unchangeable principle is not to touch any load-bearing wall. Secondly, when building a wall, steel wire mesh should be added to improve the toughness of the wall, so that it is not easy to collapse and has stronger stability. But some construction teams will be lazy and omit this step.
18, latex paint construction
If you brush latex paint, wait until it dries before brushing it for the second time. Some workers started painting for the second time in order to catch up with the time. There are many hidden dangers in the later period, so we must resolutely put an end to them.
19. Ceramic tile glue should be used for the upper wall of large-size ceramic tiles.
Large-scale ceramic tile wall, ordinary cement mortar bonding force is not enough. Be sure to use tile glue, otherwise it may fall off later. It's very troublesome to hit people
20, metope blow be bored with child and glue
Putty is easy to construct after adding glue, but generally adding glue will make formaldehyde soar at home, so we must put an end to this construction method, otherwise it will take a long time for formaldehyde astigmatism at home in the future.
