Second-hand houses don't need decoration? I advise you not to be so naive! There are many precautions in the decoration of second-hand houses!

Now the second-hand housing market is very hot, because the geographical location is superior, and they are all school districts, and the surrounding facilities are also very sound. But most of the second-hand houses are old communities that have been out of date for many years. Starting with second-hand houses, most owners must pay attention to the renovation and renovation of old houses. Many people don't need to decorate second-hand houses, but they don't know that second-hand houses need to be decorated. There are many precautions.

First, what should I pay attention to in the decoration of second-hand houses?

1. Reasonable renovation, understand the room structure.

Many second-hand houses want to modify the layout when they are renovated to make the space more practical. If it is necessary to remove some walls in the adjustment of apartment structure, we must remember that the load-bearing wall must not be removed. The bearing wall is related to the stability of the structure, and the consequences are very serious. It is also not allowed to drill holes or open doors on the load-bearing wall at will, which will bring extremely serious hidden dangers.

2. The aging water pipe 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 pipe is used in the original pipeline, it must be completely replaced during construction. It is recommended to use pure PPR water pipes.

3. The circuit must be reformed.

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 must be used when burying the lines.

4. Take cover engineering to do well

What is a concealed work? In the process of construction technology sequence, after the work of the previous procedure is completed, the part that can't be checked and covered by the next procedure is called concealed engineering. When decorating second-hand houses, special attention should be paid to concealed works. If you want to block the floor drain before decorating the bathroom, put about 5 cm deep water for testing. If it leaks, you must redo the waterproof work; At the same time, it should be noted that no dead ends can be left after construction.

5. Doors and windows should be carefully updated.

The aging of doors and windows is also a prominent problem of second-hand houses, but if the materials are solid and you like the style, you can look brand-new by repainting, but if the following problems occur, you must tear them down and redo them. If you look at the wooden doors and windows for peeling and deformation, 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.

Second, these are the key points.

1, all the old materials are replaced with environmentally friendly materials.

In home decoration, many materials used in some second-hand houses have been upgraded to environmentally friendly materials, so it is best to replace them in the following situations. The original wall surface and top surface base are sand-lime walls, which need to be removed and re-made with cement plastering base. Second-hand housing circuit aging needs to be replaced. Because modern household appliances are widely used, the replaced wires need to meet the national standards, so galvanized iron pipes need to be set up during construction. When wiring, it should be arranged according to the new design scheme, which is generally divided into lighting, low-level socket, high-level socket and weak current.

The original decoration of second-hand houses generally uses hydrophilic gypsum putty, which needs to be completely eradicated before it can be replaced with water-resistant putty. With the consent of the property, external doors and windows can be replaced. Nowadays, plastic steel windows and aluminum alloy windows are generally used. Galvanized iron pipes and aluminum plastic pipes are widely used in the waterways of second-hand houses, which can no longer meet the needs of modern life. Waterway galvanized iron pipe is easy to corrode and harmful to human health, which has been banned by the state. Aluminum-plastic pipes are easy to fall off, and water seepage causes hidden dangers in later use. Therefore, PPR pipes are often used now, and experiments need to be suppressed after the construction of new pipes is completed.

2. The surface thickness of the floor is necessary.

Floor renovation is to restore the old floor as new by polishing, scraping putty, painting and waxing the floor surface. Compared with re-purchasing the floor, the old floor has adapted to the indoor environment, with better stability and much cheaper decoration cost. But not all floors can be decorated. There is an alumina wear-resistant layer on the surface of the laminate flooring. Renovating the floor will destroy its wear-resistant layer and aggravate the aging of the floor, so the strengthened floor cannot be renovated. Only solid wood flooring, solid wood composite flooring and bamboo flooring with a surface thickness of 4 mm can be renovated. Because the surface layer of the floor will be ground off 12 mm after several polishing, if the surface layer of the floor is too thin, the middle layer will also be ground flat, thus affecting the service life of the floor.

The water leakage in the bathroom caused trouble.

Don't think that the second-hand house has been occupied by the previous owners, and there will be no problem with waterproofing. In fact, people often complain about the leakage of lower-level owners after moving into second-hand houses. Because the house is too old or the original waterproof is not done well, many second-hand houses have water leakage in the bathroom space. It is suggested that before moving into a second-hand house, it is best to do a closed water test in the bathroom space to check how the waterproof treatment was done before. You'd better say hello to the guide downstairs before the exam. In case of water leakage, you can get the understanding and cooperation of the tour guide. If there is a problem, be sure to make it waterproof again and then start tiling.

4. Dismantling the structure at will leads to the collapse of the wall.

The apartment structure of second-hand houses is often not very good, so some netizens are already planning to modify the structure of the house when buying second-hand houses, where to add a porch, get through a wall and so on. Because the multi-storey residential buildings in cities are mostly brick-concrete structures, the wall is first a load-bearing seismic component, and then a separation component. If the load-bearing wall is interrupted to expand the space, it will weaken the load-bearing and seismic capacity of the wall members, leaving serious hidden dangers. Therefore, dismantling and changing the structure at will may bring all kinds of troubles, such as wall cracking, collapse, circuit impassability and so on.

5. The newly painted wall often loses paint.

Why did the second-hand house choose brand-name paint, and the newly painted wall still fell off frequently! It is not appropriate to paint the wall directly before painting. Generally, it is necessary to remove some mottled old paint surfaces, and then start painting from a new interface, including waterproof bottom. It is best to invite professional construction personnel, so as to better ensure the future use effect.

Although I bought a second-hand house, I have to decorate it well and live a good life. Only when the family is beautiful can we live happily and feel good. At present, the decoration of second-hand houses is no longer just to meet the needs of temporary occupancy and provide us with a place to live, but the owners and their families hope to have a better indoor living experience and make our life better and better.
