Nowadays, with the oddly high prices, many people will choose to buy second-hand housing as a transition. The second-hand housing is generally renovated and needs to be renovated. The renovation and renovation of the old house has more demolition than the new house, so we think that the renovation and decoration of the old house can be regarded as two parts of the transformation of the old house and the conventional decoration. Among them, the transformation of old houses is mainly divided into three steps: demolition, hidden construction, basic construction, and finally, conventional decoration. Here we take a look at the flow of the old house decoration steps to explain it.
| The old house renovation steps process |
Demolition mainly refers to the removal of doors and windows, the removal of floor tiles and floor tiles, the removal of non-load-bearing walls, and the removal of water heaters.
The demolition project may seem simple, but when it is done, it is not at all simple. When there is a demolition work done by the owner who is doing the renovation of the old house, he looks directly at the downstairs of his house and finds several laborers who look very powerful. However, these handymen are In the demolition project, which of the demolition works and which ones should not be demolition do not understand it, but they picked up the sledgehammer and smashed it directly. As a result, on the second day after the completion of the renovation, the decoration company's master found that the circuit of the kitchen had a problem. When the handyman widens the door of the kitchen, it cuts off the circuit buried in the wall. Then he finds that the water in the bathroom is blocked. Once the original floor drain is filled with the bricks and ash, it is even worse. The neighbor of the owner came to the door and said that it was the bathroom of his family that was separated from the wall of the owner's house. The tiles on the wall were shattered and the owner was required to compensate him.
From this, it can be seen that the old house renovation and demolition project must not be dealt with by a handyman who does not understand professional decoration knowledge, otherwise it will bring more trouble to himself.
1. Doors and windows removed
Aging doors and windows is a prominent problem in the old house, but if the material is strong, and you also like its style, in general, as long as the repaint can be a new look, but the wooden doors and windows from the skin, deformation, must be replaced. In addition, the surface of steel doors and windows falling off the paint, the main corrosion or cracking, in addition to unsafe, it is difficult to restore the original state, in order to not affect the use of results, it should be removed to redo.
2. Wall surface demolition
If the wall is water-resistant putty, it is difficult to shovel, it is not necessary, so generally can be retained, the re-painting process can be directly painted after sanding can also be painted and then put two coats of repainting, if the small cracks in the wall comparison If you have more, you must first stick kraft paper or even good cloth. If the wall skin is not water-resistant, you can shovel it off again.
When smashing wall tiles and floor tiles, avoid crushing the sewers with debris; only solid wood floors, engineered wood floors, and bamboo floors with a surface thickness of 4 mm can be refurbished. In addition, local refurbishment can also cause new and old differences between floors, so consumers cannot blindly refurbish the floor.
3, water removal
There are many unreasonable layouts or corrosion of the original waterway pipelines in the old houses, so the decoration masters must thoroughly inspect the waterways. If the original pipeline is a galvanized pipe that has already been eliminated, it must be replaced with a copper pipe, an aluminum-plastic composite pipe or a PP-R pipe during construction.
4, circuit removal
In the old houses, there are common phenomena such as simple circuit distribution, aging of wires, illegal wiring, and so on, which can no longer meet the demand for power consumption of modern households. Therefore, it must be completely rebuilt and rewired during the renovation. Since the previous wire was made of aluminum wire, it was necessary to replace it with a copper wire, and PVC insulated wire bushings were used. For the installation of air conditioners and other high-power electrical lines to run separately; As for the socket problem, we must add more sockets, because the socket of the old house can not reach the number of electrical applications.

Covert construction: waterproof construction, waterway reconstruction, circuit reconstruction.
1, waterproof construction
(1) Brush the first pass of waterproof paint. Before construction, ensure that the construction site is clean and dry. The waterproof coating should be completely filled with no missing material. It should be firmly bonded to the grass roots, free of cracks, bubbles and no shedding. The brushing height is the same. The thickness must meet the product requirements.
(2) Brush the second time waterproof coating. Note that there is a certain time interval between the first and second pass of the waterproof coating. After the first pass of the coating, the second pass can be performed. The specific time depends on the coating. The interval time is too short, the effect of waterproofing will be greatly reduced, so the decoration owners should pay attention to whether the construction workers have completed all the procedures.
(3) shop protection layer. In order to prevent the subsequent construction from damaging the waterproof layer, a protective layer should be applied on the surface of the waterproof coating. The protective layer must completely cover the waterproof layer without any omission. It has a strong bond with the grass roots, no cracks, no bubbles, and no shedding.
(4) Closed water test. In the closed water test, the water at the highest point on the ground must not be lower than 2 cm, and it should be stored for at least 24 hours, and it should be considered as qualified after observing no leakage. If there is leakage, it needs to be redone and you must not neglect it.
2. Waterway reconstruction
(1) Replace the water valve. The waterways of the old houses are mostly galvanized pipes, which are prone to rust, fouling, and bright pipes. The renovation of the new house can be partially rebuilt and replaced. The old house is best replaced from the main pipe diversion valve. Since the bathroom of the old house is not very large, the total amount of replacement of the water pipe will not increase much. Under the premise of ensuring the safety of water supply, the pipelines used in the renovation should be as short as possible, but they should also be easy to maintain and look beautiful.
(2) The waterway opens and the dark pipe is opened. The bathroom of the old house is small. In order to expand the space, it is very necessary for the waterway to open and remove the dark pipe. However, the water pipe buried in the wall cannot have a joint, and it is better to have a complete pipe. In general, nine out of ten pipe leaks are problems with joints. It is best to use pressure equipment to perform the pressure test before the water tube is installed and sealed. The general construction team replaced the pressure test with whether the water pipes leaked under normal conditions.
(3) Before the new pipeline, clean the old pipeline. The original sewage pipes and floor drains of the old houses could not meet the needs of modern people. Only by adding pipes to move the water outlets, before the new pipelines and old pipelines were docked, it was necessary to check whether the old pipelines were unblocked. At this time, clean-up would avoid many future trouble. Many modern new style toilets cannot directly use the original sewage outlets of existing houses due to problems such as pit distance and drainage methods. It is not easy to move the location of sewage outlets. The above problems generally require the use of a toilet shifter.
(4) After the completion of the waterway transformation, the pressure test shall be conducted on the water pipe with a pressure machine.
3, circuit transformation
Circuit reconstruction construction program is generally: the construction personnel to determine the positioning point with the owner of the design drawings → → protection of the finished product at the construction site → according to the line to strike the line → according to the strike of the bullet line → opening box → clean up the residue soil → electric pipe, box fixed → Wear steel wire puller → connect all kinds of strong and weak wires, do not expose it outside → close the electric trough → Accept acceptance test for strong and weak electricity.

Basic engineering construction: basic house wall surface treatment, house renovation, door and window replacement, balcony insulation and so on.
After the demolition project and concealment work are carried out on the old house reconstruction, the next step is to carry out the basic project. The basic project includes the masonry project, the hydropower installation project, the muddy water project, the woodwork project, the paint project and the hydroelectric installation project. Before these projects are carried out The decoration owners need to buy the necessary auxiliary materials and main materials for the decoration so that the renovation project can be carried out smoothly.
Before the renovation project begins, the decoration owner needs to determine the building materials listed by cabinets and foremen. Before the cabinets are installed, they need to be door-to-door three times. One time is the initial measurement before installing the tiles, and the second is the accurate measurement after the tiles are installed. Finally, before the renovation, the foreman will give the decoration owner some of the building materials to be purchased before the start of construction, such as pipes, wires, waterproof coatings, and other accessories.
After the renovation is started, other building materials will be purchased according to the renovation construction steps.

Routine renovation: As long as the demolition and concealment works are done, conventional decoration is actually very easy.
The conventional decoration is similar to the steps of new house decoration. They are woodworking, bricklayers, painters, ceilings for kitchens and cabinets, cabinet installation, wooden door installation, floor installation, paving wallpaper, radiator installation, switch socket installation, lighting installation, and hardware. Sanitary ware installation, curtain rod installation, pioneering cleaning, furniture approach, appliance installation, furniture, etc.
