How long can I stay in the renovation of second-hand houses? How to make formaldehyde dissipate quickly

Second-hand houses are also divided into new houses and old houses. The new house only needs simple decoration, and the old house may need large-scale renovation. So we should talk about it in two aspects. Let's find out how long the second-hand house can live after renovation.

One: the simple decoration of the house you lived in: if you only deal with the walls and floors, the time will be very short ... you can only paint the walls and tile them. If it is well ventilated, you can move in in about ten days, but if the furniture you buy is made of different materials, it is hard to say whether it will cause air pollution. If conditions permit, I suggest you seal the room for 24 hours or 48 hours, and then ask the relevant departments to check whether the pollution index exceeds the standard. If the conditions do not allow, you can enter the room after sealing to smell the smell. If you feel strange after staying for a while, some harmful substances are tasteless. It will take about half a month if there is no new wooden decoration. If you use wooden boards, wait at least 2 months before you go in. No matter how anxious you are, you have to wait until the smell in the room clears before you can move into the main paint, paint and furniture. If you are in a hurry to move, you should strengthen indoor ventilation, put a salt water basin in the room, or chop up onions and soak them in the basin. Can effectively drive away the paint smell of the new brush. Before moving, put a few pots of chlorophytum, aloe, ivy and other plants indoors, which is very beneficial to purify the indoor air. It takes about 20 days. ...

Second, the old house was completely renovated.

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. When decorating second-hand houses, pay attention to painting the walls. Ignition is the key. The walls of old houses will crack and peel off. Therefore, when decorating second-hand houses, we must pay attention to basic treatment. 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 greasy, and putty is generally used. 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, and 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 decorative panel, 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 necessary switches and sockets. Generally speaking, a room should be equipped with at least three 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.

The above is all about how long you need to stay after the renovation of the second-hand house.
