Myth 1: The load-bearing wall cannot be demolished, and the non-load-bearing wall can be demolished casually.
Many second-hand housing renovation strategies will suggest destroying some walls in the renovation of huxing, and emphasize that non-bearing walls can be removed. This has created a kind of cognition for everyone: "The load-bearing wall is related to building safety and cannot be demolished. The non-load-bearing wall can be demolished at will."
The so-called non-load-bearing wall refers to the wall composed of reinforced concrete column array frame, which is a secondary load-bearing component, but also an extremely important support for the load-bearing wall. Wall, first of all, is the load-bearing seismic component, followed by the enclosure partition component. If it is a small-scale demolition, it is no problem to tear down the load-bearing wall or make holes in the wall. However, if many non-bearing walls in the whole building are demolished at will, the seismic performance of the building will be greatly reduced, and there are serious security risks. shzyshange44
Countermeasures: decorate the wall with wallpaper or hanging pictures, and make up for and decorate the deficiency of the apartment with home layout, such as closet.
Misunderstanding 2 ignores the transformation of walls, floors, ceilings and other walls.
According to the age of the second-hand house, the walls of the second-hand house are aging to varying degrees. For the sake of safety, it is best to ask professionals to check the house, mainly to check whether the wall is flat, peeling/sanding/obvious cracks, water seepage marks, etc. If these conditions exist, the cracks, peeling and sanding on the wall surface need to be repaired, and the water seepage needs to be completely leakproof.
In addition, when shoveling the wall skin, if the room is only decorated for one or two years, you can use steel brush and sandpaper to polish the wall surface and then brush the water-resistant putty. The water-resistant putty for more than five years must be eradicated to the bottom of the wall, otherwise it will affect the construction quality of the wall latex paint and the long-term use effect after decoration in the future.
Myth 3: Renovation of wooden floor means repainting and maintenance after polishing.
The old floor has adapted to the indoor environment and has better stability. By polishing the floor surface, it can be restored as new, and the renovation cost is much cheaper than re-purchase, so many owners choose to renovate the floor. However, it should be noted that according to the classification of wood floors, the applicable decoration methods are also different, and some wood floors cannot even be decorated:
Pure solid wood flooring: polishing and renovation can be completely adopted, and some flooring manufacturers can provide renovation services for a fee;
Solid wood composite floor: grinding will destroy the wear-resistant layer on the floor surface, and only the renovated solid wood composite floor with a surface thickness of 4 mm can be polished;
Laminated floor: This floor is made of sawdust, and the wear-resistant layer on the surface is relatively thin. Polishing and renovation will aggravate the aging of the floor and greatly shorten its service life, so it can only be replaced.
Misunderstanding 4 ignores the inspection of ground waterproofing.
Kitchen and bathroom are the places where daily water is used most frequently. There are many pipes, and it is easy to leak water where it passes through walls and floors. We can't take it lightly just because the owner has lived in front of us. Old rooms or poor waterproofing can easily lead to water leakage and neighborhood disputes. Therefore, before renovation, the kitchen and bathroom need to be waterproof for 24-48 hours. If there is leakage, waterproof construction needs to be done again during decoration. After waterproofing, wait until the ground is completely dry before laying tiles for overall decoration.
Myth 5: In order to save money, continue to use the original catheter without replacing it.
Circuit: There are many phenomena in old houses, such as simple circuit distribution, aging wires and disorderly wiring. Moreover, the wires used in old houses before 1995 are generally aluminum wires, and copper core wires have not been applied, which can not meet the electricity demand of modern families. Therefore, when decorating, it is necessary to completely transform and rewire the circuit.
It is suggested to make a good plan before construction, and consider the loop and conductor of the circuit according to the usage. If the original lines are found to be aluminum wires, they must all be replaced with copper wires with a cross section of 2.5 square millimeters; For lines with 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 should be used when burying the lines.
Waterway: The water pipes in old houses are mainly galvanized pipes, which are often corroded and aged, and the scale is serious. Therefore, it is necessary to check whether the original waterway pipeline (including heating pipeline) is corroded and aging, and replace the galvanized pipe with copper pipe, aluminum-plastic composite pipe or PP-R pipe.
Gas: The gas pipeline is dangerous, so it is best to ask professionals to check it. shzyshange44
Myth 6: rashly change the balcony into a kitchen.
In order to broaden the use area, some homeowners will close one of the balconies and turn it into a kitchen, while the original kitchen will be used for other purposes. However, this can easily lead to problems such as rampant soot after check-in. First, after the balcony is closed, the indoor ventilation effect is greatly reduced, the kitchen fume is difficult to disperse, the cleaning workload is greatly increased, and the lighting degree of the living room will be relatively reduced; Second, the problem of pipeline diversion caused by changing the balcony to the kitchen, gas pipes, water pipes and other pipelines need professional modification design and construction, but also pay attention to waterproof problems; Third, the bearing capacity. In view of the fact that the balcony is an extension of the building with limited bearing capacity, it is necessary to budget the weight of decoration materials before the renovation.
Changing the balcony into a kitchen is not an ideal choice in terms of use effect or construction cost, so the owner should choose carefully when considering the modification.
Finally, I attach two small suggestions. First, second-hand houses should be thoroughly disinfected before moving in. The specific operation is as follows: spray the whole house with 3% Lysol water, 1-3% bleaching powder water or 3% peracetic acid solution, and close the doors and windows 1 hour after spraying; Secondly, there is no need to replace all the old furniture. Toxic substances such as formaldehyde in furniture volatilize for a long time, and old furniture is relatively safer. Therefore, according to the style of the new home, it is not only environmentally friendly and economical, but also a good choice.
