What hidden works are there in the renovation of second-hand houses?

Second-hand housing decoration should pay attention to:

1, do a closed water test for the bathroom.

Before the renovation of second-hand houses, attention should be paid. First of all, please ask the decoration workers to carry out a closed water test on 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 treatment and circuit transformation

Second-hand housing decoration should pay attention to the transformation of water and circuits, which is the most complicated in the transformation 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 is made of aluminum wire, attention should be paid to demolishing the second-hand house. There are many modern household appliances. According to the national standard, 2.5 mm copper wire must be used in decoration, and the wires for installing high-power electrical appliances such as air conditioners should go by themselves. When burying wires in the wall, PVC insulated pipes must be used.

3. Pay attention to painting the wall in the decoration of second-hand houses, and priming is the key.

Cracking and peeling will occur on the walls of old houses, so we must pay attention to the basic treatment when decorating second-hand houses. 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, second-hand housing decoration should pay attention to scraping putty. Putty paste should be waterproof and not greasy, putty should be scraped three times, and finally latex paint should be brushed. If you want to paint the wall, you should paint it with primer accordingly.

4. Pay attention to replacing aluminum alloy or plastic steel doors and windows in the decoration of second-hand houses.

Pay attention to wooden doors and windows in the decoration of second-hand houses. If there is no deformation or cracking, it means that the material is very good. When decorating, you can stick a veneer, and then paint it and continue to use it. If the wooden doors and windows have been deformed, they must 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 necessary switches and sockets.

Nowadays, more and more electrical appliances are used in the 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, in the decoration of second-hand houses, attention should be paid to wiring in advance, and what places need to be placed in the future should be planned in advance, while the switches and sockets reserved in 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. When decorating second-hand houses, it should be noted that the switch height of 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 set the switch in the living room where the owner can easily reach it.

6. When decorating second-hand houses, we should pay attention to disinfection and keep indoor air circulation.

In the whole process of second-hand housing decoration, 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. When decorating second-hand houses, we should pay attention to regular and thorough disinfection during the decoration process. We can spray 3% Lysol, 1%-3% bleaching powder water or 3% peracetic acid solution. Close doors and windows after spraying 1 hour.
