As the old saying goes, the rabbit can't run too eagle. During the renovation process, most customers and constructors are like this kind of relationship. Everyone has unlimited power when they get the key to a new house. They all believe that he is a very powerful person. However, when Teng Tzu moved to his new home and stayed for some time, comforting himself that he would be able to stay safely, he would carefully recall how he was a strong man. He was only powerful, but actually a weak lamb. And throughout the renovation process, it is always a weak person.

As a person who has been "decorated" by renovations, many consumers have expressed that they are still totally ignorant of the "craftsmanship" of decorating the building. At the time of the renovation, they got headaches on the construction site and saw piles of cement, sand, and pipelines. The pots and barrels will be in trouble. When he wanted to supervise the construction of workers, he found that he could not start. Standing on the construction site still feels that they are obstructing themselves, and they have to laugh at the foremen and workers. They expect that they will feel sincere in their smiles and can do a better job. However, if you have a good luck, bad luck may cause a variety of problems and make you lose your head.

Try to understand what the construction site should look like. In the process of visiting the construction site, I hope that through the capture of details and the tips given by the experts, I will let the consumer who knows how to decorate the building know about the norms and procedures of the construction site. Through the advice of the experts and the support, the consumers can rub it. Bright eyes.

In the renovation, in addition to ensuring that the materials are qualified, it is also necessary to examine whether the decoration site is tidy and orderly, and whether the decoration site is standardized and whether the construction site is reasonable and safe.

Learn to visit the construction site and be aware of "supervising workers"

A material classification placed to avoid pollution

Regular home improvement companies generally place project schedules and supporting tools in a prominent position, and the decoration site is also relatively tidy.

Decoration materials should be placed in categories and materials that are easily contaminated with each other should be placed separately.

Visit target: whether the materials are stacked neatly before the construction

[Decoration specification] Pay attention to the material properties when placing the code

1. The materials should be classified and placed in the same category. The same kind of materials and the same property materials should be classified and placed neatly. The materials that are easily contaminated with each other should be placed separately. The flammable hazardous materials should be placed separately in the safety place where few people walk around. The materials should be neat and tidy. place. For example, paints, coatings and plates cannot be mixed.

2. Material code can not change the physical and chemical properties of the material, can not cause mutual contamination of materials, can not cause deformation of the material, can not cause security problems, can not cause damage to the package. For example, ceramic tiles cannot be placed on sand or cement, and buckets that have been painted or painted cannot be placed on plates.

3, Daxin board, gypsum board and other best code in the living room, between the board and the board should be dense, can be placed flat or side. When laying flat, you should padded it with three wooden pillows. The major or major pieces of the board should be placed below. The side angle should be greater than or equal to 75 degrees.

4, cement, sand, floor tiles, wall tiles, etc. should be placed on the water, where people walk around, can not be placed on the kitchen, bathroom, balcony. White latex, adhesive, paint, and wall paint should be placed in a single bedroom, out of direct sunlight, without fire, and with few people moving around. The hardware code is placed on the hardware box and each bag is packed in a separate bag. Items of customers such as sanitary ware, locks, handles, lamps, etc. must be packed in the bedroom with bags.

5, material placement should be selected in the place where there is no decoration project, do not close to the window, do not close to the water source, do not place in a position that may cause injury and fall, to prevent theft and loss of materials, in order to facilitate the construction of the wall, from the wall 0.8-1.0m.

6, construction tools should be placed in the toolbox, immediately restored after use. The construction bench should be placed in the center of the living room and parallel to the wall. In addition, pollution-intensive work, such as cutting tiles, etc., is best done on the balcony. Stirring the cement requires the use of special tin box mixing.

7. Garbage should be packed in woven bags, cleaned twice a day, and transported once.

Two hydropower lines should be clear and clear

When the waterway is reformed, it is generally necessary to conduct a pressure test first.

The transformation of the water pipe should be simple and clear, and the waterproof of the bathroom must also be done well.

Visit target: hydropower reform

[Decoration specification] Walking pipe line reasonable and orderly

1. Slotting: When retrofitting additional water pipe wires, the wall slot can not be thrown horizontally, and should be thrown vertically, because the horizontal throw is more damaging to the wall, and the shock resistance and strength are greatly damaged. It can only be thrown vertically. The length of the horizontal throw cannot exceed 3-5 cm. If the slot is deep, it is easy to hit the steel in the wall and saw the steel bar broken. If it is bad, it will be easy to swell in the future.

2, wire: wire tube material is pvc tube, wire tube can not be damaged, with burrs. If you take a dark line, the depth and width of the slot should be more than 1.5 times that of the cable. The wires in the wire conduit should be color-coded and must not be damaged or kinked. When strong and weak electricity pipes cross, shield protection should be done.

3, water pipes: the ground should not take the water pipe, should be on the wall or the top surface of the water pipe. If the water pipe is on the top, the electric pipe should be on top and the water pipe should be down. There should be no joints in the dark tank water pipes. Water pipes should reduce detours. If the ceiling material uses gypsum board, the water pipe should be used for heat preservation.

4, waterproof: Check whether there is empty drum and loose, if any should be repaired. All kinds of pipelines, sewage pipes, floor drains, casings, sanitary ware roots, and yin and yang corners must be made waterproof first. Waterproof brush must be completed 24 hours closed water test, no problem to continue the next process.

5, floor drain: To close the excess floor drain, be sure to gap between the drain pipe and floor drain with glass adhesive or cement block to prevent the flow of water spill and return. Washing machine floor drain is best not to use deep water sealing floor drain, mainly because of the deep water seal leakage has a common feature is the slow water, used in showers and other locations of deep water sealing leakage, due to the amount of water is not large, the floor drain can basically meet the drainage needs; However, the speed of the drainage of the washing machine is very fast, and the displacement is large. The rate of water entering the deep water seal leakage cannot be satisfied at all, and the result will directly lead to the overflow of the water.

Three floor tiles are protected after being laid

After sticking the brick, tap the surface with a rubber hammer to fix the tile.

After the floor tiles are laid, they should be protected for the first time.

[Decoration specification] First wall treatment when tiling

1. If the wall is a rough concrete wall, the tile can be tiled directly after the wall is pulled. If the wall surface has been smoothed, the wall must be shoveled before the tile to expose the cement base, and then the wall should be cemented. After the surface is napped, tiling is performed again to increase the adhesion of the cement mortar and the wall surface to prevent detachment.

2, before the tiling should clear the grassroots, such as lime plaster on the wall, latex paint, wallpaper and other decorative objects, or dirt on the ground, be sure to clean, otherwise the cement mortar and the grass roots adhesion is not strong. In addition, if the wall itself has cracks, it should be properly treated before it can be tiled, so as to avoid future basic structural cracks caused by cracking or loss of wall tiles.

3, wall tiles have a high moisture content, tile base should be fully wet before the tile, ceramic tiles should also be soaked in water for at least 20 minutes before use.

4. Bricklayers must require brickwork to pull the line and supplement the level rule to control the quality. Wall tiles should be laid up from the bottom up, leaving a brick at the bottom. When the floor is finished, the bottom wall of the wall is pressed against the floor tile. A wall cannot be affixed to the top at a time to prevent the tile from being heavy and causing it to fall. After sticking the bricks, the rubber hammer is used to strike the surface to fix it, which can prevent the air from accumulating in the adhesive layer, and at the same time, carry out level detection.

The tiles are affixed from the middle to the sides, and the bricks are cut short before they are cut.

5. After laying for 1 hour, the cement, caulking agent or other dirt left on the brick surface should be wiped clean in time. After 12 hours of paving, check the bricks and inspect if there is any empty drum sound. Paving bricks can be walked after 24 hours, scrub thoroughly, mix the clean water with clean water, and thoroughly clean the tiles.
