With soaring house prices, many consumers will consider buying second-hand housing in an economic and cost-effective manner. However, the renovation of second-hand housing does not require the removal of the original decoration, then what projects should be rectified for the transformation of second-hand housing ? Let's look at it together.

What do you need to do in the renovation of second-hand housing?

1, replace the breathable and soundproof doors and windows

Replace the original non-insulated and non-insulated doors and windows, such as the use of hollow glass flat open (hanging) doors and windows to replace the old sliding doors and windows, conditional replacement of more environmentally friendly and energy-saving aluminum doors and windows broken bridge; not insulation and sound insulation The entrance door is replaced with three doors for insulation, sound insulation, fire prevention and ventilation. Replace non-insulated interior doors with soundproof wooden doors with seal strips.

2, thermal optimization

Some of the old house balconies and outer walls have not been insulated or the insulation measures are unreasonable; the use of lightweight bricks, extruded plates, and thermal insulation rock wool materials with superior light insulation properties are performed at these locations where insulation performance is weak. Insulation and soundproofing.

3, to solve the problem of cracking on the wall

It is not uncommon for second-hand housings to crack and crack. However, if we do not carry out grassroots processing, and directly refresh the paint, it is a temporary solution. Therefore, in the renovation of the wall, we must get rid of the original non-environmental water resistant ordinary putty, replaced by more environmentally friendly and reliable anti-cracking putty. For the original local hollow drum cracking on the wall and floor base, it must be removed to a solid base layer, and then the kraft paper tape and the glass fiber grid are applied to prevent cracking.

4, waterway optimization

According to the shower, wash basin, toilet, washing machine, vegetable sink, mop pool, water purifier, electric water heaters, gas water heaters, add some water inlet, outlet, drain outlet. Replace the original old pipeline with a PPR pipe (preferably a PPR composite copper pipe) and replace it with a dark pipe.

5, circuit processing

The distribution box settings of second-hand houses are generally relatively old, the circuit is too simple, and the power ratio of each loop is not reasonable. It is necessary to plan a safe and reasonable circuit design based on the power of all the power equipment. In an ideal state, the switch box should be five switch circuits: master switch, lighting, common socket, air conditioner, kitchen and bathroom socket. If there is a fast-fired water heater, it is necessary to add a separate circuit of 6 square copper wire.

5, increase the necessary switch socket

With more and more appliances used in homes, lighting and lighting equipment are becoming more and more colorful, so there are many places where switches and sockets need to be placed. Well, before the renovation, we must do a good job of wiring in advance, which places need to be placed in the future, to do a good job in advance planning, and the old house reserved switches and sockets are generally not enough. In general, a room must have at least 3 outlets. There should be no fewer than 15 sockets in a two-bedroom residential building and no less than 8 switches. The switch height of the same room should be the same, the general switch is 1.4 meters from the ground, and the outlet is 0.3 meters from the ground. The switch between the suspension and the living room should be set in a place easily accessible to the owner.

Conclusion: The amount of second-hand housing renovation projects is relatively large. We must rationally use some of the design and decoration before housing so that we can guarantee the effect of housing renovation. On second-hand housing renovation to introduce here, I hope you used in the decoration of houses when to pay attention to the details of the problem.
