27 places where decoration companies cut corners.
When the masonry wall is demolished
1, there is no hanging net at the junction of the old and new walls, and the new wall must be painted. Many bad decoration companies cut corners and don't hang up the net. Anyway, the owners can't see it.
Hidden trouble: Cracking and wall inclination may occur in the later period without hanging the net.
2, the eradication is not clean, and some workers shovel casually! This batch of lime must be removed by spraying with water, and some lime must be polished off. To shovel the white ash to the end, only the cement mortar layer can be seen.
Hidden trouble: If it is not cleaned, it is easy to shell and fall off when painting.
The white wall has not been eradicated. The top surface of many new houses has been recognized by developers, and it is generally recommended to eradicate them. Some workers are lazy and have not been eradicated.
Hidden trouble: Paint latex paint directly on the original white wall, which will shell and fall off after a long time.
4. The bathroom waterproof has not been repainted, and the original waterproof quality of the bathroom is generally poor. Basically, it is necessary to brush the paint and repaint the waterproof. Workers are lazy to keep the original waterproof, and then simply brush it on it.
First, when tearing down the wall.
Hidden trouble: if the old waterproof layer in the bathroom is not removed, the new waterproof layer and the old waterproof layer will not only lose their waterproof function, but also often empty and fall off in the later stage.
5. The construction waste is directly poured into the sewer. In order to save trouble, the decoration workers may directly pour the construction waste or decoration waste into the sewer.
Hidden trouble: this will cause poor sewer pipes.
Second, the bricklayer's construction
6. When laying tiles, cement is mixed in the tile glue. The price of tile glue is higher than that of cement mortar, but the wall must use tile glue. Some builders use tile glue and cement to lay bricks in order to save costs.
Hidden trouble: Cement mixed with tile glue will weaken the adhesion of tile glue, and the first brick may empty and fall off every time.
7. The wall tiles are laid carelessly, and the technical content of wall tiles is high. Workers are easy to perfunctory construction, and owners are not easy to find hidden dangers: careless construction, easy hollowing of tiles, uneven joints and falling off.
Second, the bricklayer's construction
8. The water surface is uneven. If the ground is not flat enough, it needs to be leveled. Some decoration workers clearly received leveling fees, but did not do any hidden dangers: the floor was not leveled and then paved, and there would be unequal side seams on the wooden floor.
9. Tile paving does not "nap". Tiles should be laid directly on the wall with water. It is necessary to do "napping" treatment to make the wall surface rougher, which is conducive to the close fit between ceramic tiles and the wall surface, and it is not easy to appear empty drum. Although there are many reasons for hollowing out, workers cut corners is one of the important reasons.
Hidden trouble: Tile paving does not directly "nap" on the wall, which may lead to tile falling off and endanger personal safety.
Three, when the hydropower transformation
10, the threading number of electric conduit exceeds the pipe diameter, and the threading number of electric conduit shall not exceed 40% of the pipe diameter, so as to ensure that it can be easily pulled out when replacing new wires.
Danger: Too much threading of conduit will easily lead to accelerated aging of wire insulation.
There are hidden dangers of wire short circuit and even fire.
Three, when the hydropower transformation
1 1. There are connecting wires in the conduit, and connectors are not allowed in the conduit. However, in order to save materials, it is difficult for decoration companies to find the joints hidden in the conduits. Danger: There is a connector in the catheter. Once the connector is aged or short-circuited, maintenance is easy to happen.
fire
12, it's easy to cut corners if you don't attend the inspection in person during the water and electricity decoration.
13, it is common for workers in the same pipe/trough on the strong and weak lines to be lazy, not slotting or setting another pipe.
Hidden trouble: Strong and weak wires are in the same slot or tube, and weak current will only be destroyed by strong electromagnetic interference, which will affect network communication.
14, wires are exposed without protective measures, bearing walls and suspended ceilings cannot be opened with deep grooves, and electric conduits are not applicable. It is common for some workers to cut corners and directly expose this section of wire.
Hidden danger: The exposed wires are directly covered with cement in the later period, and the insulation layer of the wires is corroded for a long time, which may easily lead to accidents such as electric leakage.
Three, when the hydropower transformation
15. Slotting is not standard. In hydropower construction, it is necessary to slot the wall and ground. It is forbidden to slot the load-bearing wall and beam. The groove length of non-bearing wall should not exceed 50 cm. Hidden trouble: the wall is slotted in a large area, which is quite dry, cutting off the wall and making the wall lose.
The original bearing capacity will weaken the bearing capacity of the house; The wall with insulation layer is easy to crack after slotting.
16, the wiring does not meet the construction requirements. When installing sockets, switches and lamps, electricians use 2.5 square wires as 4 square wires, and 1.5 square wires as 2.5 square wires, which is difficult for the owner to find in the pipeline.
Hidden trouble: the wiring does not meet the construction requirements, and sudden tripping and socket heating often occur in the later use.
Four, waterproof construction 17. The waterproof structure does not reach the standard height. Workers are lazy and don't have another trough and another pipe, which is a common hidden danger. The standard of toilet is: shower area 1800mm high, dry area 300 mm, and the standard can only be high but not low during construction.
Fourth, waterproof construction
18, 2-3 layers of waterproof coating were not applied, and the decoration workers were too lazy to apply 2-3 layers of waterproof coating, and they didn't wait until it was completely dry before continuing the construction. The bottom of the threshold is a waterproof corner, which is often stolen by workers.
Hidden trouble: causing water leakage. Unless you don't use water in the bathroom, water will seep out.
Problems will lead to the rot of the door cover and door cover line, and big problems will leak downstairs, leading to economic disputes with the downstairs.
5. During woodworking construction, the door opening was changed and the back door beam was not re-poured. The renovation team's original doorway will destroy the original doorway beam, and the workers did not re-pour the doorway beam because of the trouble: the wall pressure above the doorway beam will cause the doorway to deform.
20. The ceiling gypsum board installation is not standardized, and the ceiling gypsum board should be staggered. After jointing with glue, stick a special anti-crack tape before scraping putty, otherwise it will crack easily. Hidden trouble: although light steel keel is used, it will also lead to cracking if it does not meet the specifications.
Five, woodworking construction.
2 1, the wooden keel used for the ceiling is not light steel keel, but now the ceiling is light steel keel. Wooden keel is not recommended. In order to save materials, many decoration companies use wooden keel ceilings. Anyway, the owner can't see a gypsum board.
Hidden trouble: the wooden keel is easy to deform, damp and moldy, and the most important thing is that it is easy to change doors behind the mountain.
Ceiling cracking
22. The chandelier is directly installed on the gypsum board. The chandelier cannot be directly installed on the gypsum board, nor is it recommended to be installed on the keel of the ceiling. It is best to add suspenders and keels to make the floor bear it.
Its weight
6. When the painter is working, 23. Lazy people only brush the top coat once and always stare at the painter's construction link. Paint construction process
The process is generally: gypsum putty leveling, polishing, priming and covering twice, if it is not good. Be sure to supervise. Some workers are lazy and only paint once. you
It's also hard to find.
24, joint decoration, in some joints between walls and doors and windows, and where two different colors of paint are docked, sloppy and perfunctory. It is also a place where workers often perfunctory.
6. Petroleum construction.
25, latex paint is not a prescribed brand of latex paint brushing, be sure to see the whole barrel of new latex paint. Some decoration companies take bucket brushes and have no idea where the leftovers are or are not the brand in the contract at all.
26. Untreated faces are small places that the eyes can't see and don't pay much attention to, such as the top of the door and the bottom of the windowsill. Some workers will cut corners and even do nothing here.
27, careless handling at the grassroots level, grassroots criticism is also the "hardest hit" to cut corners. The uneven wall is not thick enough, which directly affects the paving of tiles and the suspension of heavy objects.
