What should be paid attention to in the renovation of old houses?

The following aspects should be paid attention to in rejuvenating the old house with small ring of pigs:

1. Do a closed water test for the bathroom. Before decorating the second-hand house, you should ask the decorator to do a closed water test for the bathroom to check how the waterproof treatment was done before. The method is: block the floor drain, put 5 cm of water in the bathroom, observe for 24 hours, and then go to the neighbor's house downstairs to check. If there is no water leakage, it proves that the waterproof treatment is done well; If there is water leakage, be sure to ask the property to be waterproof again. After waterproof treatment, wait until the ground is completely dry, then stick tiles, otherwise the ground will crack.

2. Water and circuit renovation The treatment water and circuit renovation are the most complicated in the renovation of old houses. In the waterway reconstruction, people use the 50-year warranty rifeng pipe more. After the completion of all waterway reconstruction, the pipeline should be reasonable, closely connected, without leakage and illegal removal. In terms of circuit transformation, if the old house uses aluminum wires, it must be removed. There are many modern household appliances. According to the national standard, 2.5 mm copper wire must be used in the decoration, and the line for installing high-power electrical appliances such as air conditioners should be 4 mm square. When burying wires in the wall, PVC insulated pipes must be used.

3, painting the wall, plastering is the key. The wall of the old house will crack and peel, so when decorating the wall, we must pay attention to the treatment at the grassroots level. Generally, a good decoration company will coat the interface agent after leveling the wall. Interfacial agent has the function of moisture-proof and can also protect latex paint. Next, blow the putty. The putty paste should be waterproof and not greasy, and the putty should be scraped three times. Finally brush latex paint. If you want to paint the wall, you should paint it with primer accordingly.

4. Replace the wooden doors and windows of aluminum alloy or plastic steel doors and windows. If there is no deformation or cracking, it means that the material is very good. When decorating, you can stick a veneer board, and then paint it and continue to use it; If the wooden doors and windows have been deformed, they should be torn down and redone. Iron doors and windows, if the surface paint has fallen off or the main body is cracked, I suggest you remove it and replace it with aluminum alloy or plastic steel. Because doors and windows can play the role of sealing, sound insulation and heat insulation.

5. Add essential switches and sockets. Nowadays, there are more and more electrical appliances used at home, and the lighting equipment is becoming more and more colorful, so there are many places where switches and sockets need to be placed. Then, before the renovation, it is necessary to do a good job of wiring in advance and plan the places that need to be placed in the future in advance, and the switches and sockets reserved for old houses are generally not enough. Generally speaking, a room should be equipped with at least 3 sockets, the number of sockets in two bedrooms should be no less than 15, and the number of switches should be no less than 8. The switch height in the same room should be consistent. Generally, the switch is off the ground 1.4m, and the socket is off the ground 0.3m. Hang up and put the switch in the living room where the owner can easily reach it.

6. Do a good job of disinfection and keep indoor air circulation. In the whole decoration process, especially after gluing and painting, you must always open the window to keep indoor air circulation. If there is no window in the bathroom, turn on the exhaust fan. During the decoration process, it should be thoroughly disinfected regularly, and 3% Lysol water, 1%-3% bleaching powder water or 3% peracetic acid solution can be sprayed. Close doors and windows after spraying 1 hour.

In addition, don't move in immediately after the renovation. If conditions permit, it is best to open the window every day and keep indoor ventilation, so that toxic gases such as formaldehyde can evaporate quickly. It is recommended to stay indoors for 3-6 months after complete ventilation. Of course, the situation of each family is different, but these aspects should be taken into account when decorating second-hand houses, hoping to help friends who want to decorate second-hand houses.
