Second, avoid tearing down the load-bearing wall.
Removing the load-bearing wall without permission not only has serious hidden dangers, but also violates the relevant regulations of the state. The load-bearing wall is the main body of the house. Once there is a problem, it will not only suffer economic losses, but also be sanctioned by law.
Therefore, when decorating second-hand houses, we should pay attention to which ones are detachable and which ones are not. It is best to consult the property in advance, or ask the property for some structural drawings of the house. If there are no drawings, doors and external walls, try not to tear them down; And take a ruler to measure the thickness of the wall, it must be a load-bearing wall; These walls in the bedroom must be load-bearing walls.
Third, pay attention to control the budget of decoration funds.
The key to control budget excess is to make a strong budget before decoration. Including a lock, how much is it, and then buy it strictly according to the standard. You should also leave some room for yourself in the budget: as long as you are satisfied with how much money you want to exceed, you can deduct it from the extra money and make rational consumption.
Four. Matters needing attention in purchasing decoration main materials
1, aging water pipes must be replaced.
The original waterway pipelines of second-hand houses often have many unreasonable layouts. When decorating, you must thoroughly check the original waterway to see if it is rusty and aging. If the obsolete galvanized pipes are used in the original pipes, they must all be replaced with copper pipes, aluminum-plastic composite pipes or pp-r pipes.
The circuit had better be laid again.
Second-hand houses generally have simple circuit distribution, aging wires, illegal wiring and other phenomena, which can no longer meet the electricity demand of modern families. When decorating, they must be completely transformed and rewired. If it is found that the original lines use aluminum wires, they must all be replaced with copper wires with a cross section of 2.5 square millimeters. For the lines of high-power electrical appliances such as air conditioners, lines with a cross section of 4 square millimeters should be set separately, and pvc insulated conduits should be used.
3. "Three-sided" transformation is essential.
In the decoration, the decoration of the wall, floor and ceiling of the second-hand house is the most easily overlooked. It is best to ask professionals to conduct on-the-spot investigation on the house to see if there are obvious cracks, flatness, shedding and sand. If these situations exist, it is necessary to repair them, including removing oil stains from the wall surface, powdering the wall paint, and repairing the base, cracks and holes with cement mortar. In addition, after the repair, a primer should be brushed to cover it, which can make the base layer firm, and secondly, it can prevent the base layer from changing in the future because of flooding alkali, and then paint it with latex paint diluted in proportion. During construction, attention should be paid to the cleanliness of the air at the site, dust prevention and no sundries on the tools.
The old door lock must be changed.
The first thing to change, of course, is the door lock. As a second-hand house, it is impossible to know how many people still have the keys to the old locks. In addition, you should also pay attention to check whether the doors and windows are aging. If the material is solid, it can be repainted. If the paint film on the surface of steel doors and windows falls off and the main body rusts or cracks, it is best to tear it down and redo it.
5. Pay attention to consulting and checking the aging degree of doors and windows.
Aging of doors and windows is also a prominent problem of second-hand housing. But if the material is solid and you like its style, you can look brand-new by repainting it. But if the following problems occur, it must be dismantled and redone. The main problem is to see if there is peeling and deformation of wooden doors and windows. If so, it means that the characteristics of the wood itself have changed and must be replaced. In addition, the paint film on the surface of steel doors and windows falls off, and the main body is corroded or cracked, which is not only unsafe, but also difficult to restore to its original state. In order not to affect the use effect, it is recommended to tear it down and redo it.
6. Disinfection steps of second-hand houses are essential.
Second-hand houses can be disinfected with 3% lysol water, 1- 3% bleaching powder water or 3% peracetic acid solution. Close doors and windows after spraying 1 hour.
