[Decoration knowledge] old house clever refurbishment of old houses can also "cook up"
If it is an old house that is refurbished , then the wall should be the first place to think of changes. Demolition of the old decoration, wall treatment, structural transformation, water circuit renovations make second-hand housing renovation expensive. In fact, the decoration of second-hand houses does not need to be costly, because there are still places that can be used in the old renovations. To use them, the entire renovation cost will be much more economical. Compared with the new house renovation, the renovation of the old house is more troublesome because it adds a lot of procedures, and it takes more time than the new house - but as long as the old house can maintain the craft level during decoration, especially the clever use of the decoration paint, There is no big difference between an old house and a new house.
First, carefully design, find the transformation of the project before the renovation of the old house, the decoration company also has to carry out the overall design, involving the facade wall treatment, ceilings and other places, it is best to send professionals to carry out on-site housing exploration. Such as wall surface, floor, ceiling and other obvious cracks, whether smooth, there is no shedding and sanding phenomenon. If there is such a problem, the grassroots level must be repaired. In the repair process, it is best to use environmentally friendly interior wall putty, the product is environmentally friendly, non-irritating, regardless of the old wall of the new wall, there is a very strong adhesion, its strong permeability, like it is playing on the wall Into numerous nails, so that the original cracking or pulverization hollow wall polished smooth, smooth, smooth, easy construction of latex paint.
Second, focus on the renovation of doors and windows The doors and windows in the old house should be one of the highlights of the transformation. The degree of actinitiy of doors and windows is divided into several cases. First, if the doors and windows of wood are peeled and deformed, it indicates that the characteristics of the wood itself have changed and must be removed. If the material is compact, the surface paint film is in good condition and can be used during the second construction. Apply a decorative panel. The second is steel doors and windows, security windows if the surface paint film peeling, the main body rust or cracking, must also take appropriate measures to transform.
In general, due to the long time, it is difficult to express the natural texture of the wood with varnish, so this time it is necessary to use solid wood lacquer. This will not only cover the old lacquer, but also give a different style according to the new decoration style. The color, to achieve the magical effect of decay.
Third, the transformation of the old room walls, the top surface of the old house decoration should focus on decorative materials. Among them, the paint on the wall is the most typical. The wall of the top floor of the old house will have different degrees of cracking, chalking and mildew after being used for many years. If these problems are not solved properly, the paint on the back brush will also appear colored. Uneven, rough surface and adverse effects of skinning. This requires prior pretreatment of the base of the wall, etc.
Then, what are the links in the transformation of old houses that can reduce changes and reduce costs?
Kitchen tiles
The cost of kitchen and bathroom tiles can account for at least 10% of the cost of the main material, so if the original decoration of the second-hand house does not last long, the tiles used by the kitchen and bathroom do not have a lot of empty drums and fall off, and the style is not out of date. replace. Replacing easily prone parts such as ceilings in kitchen and bathroom spaces with new materials will refresh the entire kitchen space.
Wall treatment
Most of the old-fashioned second-hand housing walls will be cracked. The cause of cracking lies in the treatment of the grass-roots walls. If the walls are non-water-resistant putties that are easily ashed and powdered out, then such walls will need to be redone. However, if the original wall is water-resistant putty, you can consider using local patch to prevent cracking, the cost of the patch is roughly ten yuan per square meter.
Waterway reconstruction
The waterway reform can be described as a “major surgery†for second-hand housing, so it costs a lot. Generally speaking, the home improvement company renovates the waterway according to the difference between the bright and dark pipes, and the price ranges from roughly RMB 890 to RMB 100 per meter. Therefore, minimizing the waterway reform will greatly help reduce the overall renovation cost.
Whether the water pipeline needs to be transformed must first check whether the existing waterway layout meets the needs of family members. If it can meet the requirements, the existing waterway position can be maintained. And then check the material of the water pipe, many of the old house's water pipe is galvanized pipe, this pipe will produce rust in the pipe wall after many years of use, affect the water quality, and the galvanized pipe will also "sweat" in the summer, There will be a large amount of water droplets on the outside of the wall. If it is not treated with anti-corrosion and moisture, it will cause the wall to be damp.
Circuit modification
Circuit renovation is also the highlight of the renovation of old houses. Judging whether or not the circuit needs to be transformed is very important. It not only involves the increase in the overall cost of renovation, but more importantly the safety of household electricity in the future.
Most of the old houses that have reached the age of 20 to 30 years are mostly only one circuit. Such switches and sockets are dangerous for “sharing†a power line, which can easily lead to excessive circuit load. Old wires can also cause fires. .
At present, the circuit layout of most households is divided into three sections: the switch, the socket, and the high-power electrical appliances. The wire diameter is 2.5 square millimeters. If the old home circuit is such a layout, the circuit can be considered as a whole. For customs clearance, you can increase the number of sockets and switches to meet the demand for electricity.
However, the 2.5mm square wire load limit is roughly 5,500 watts, so the choice of bathroom, kitchen appliances must consider its power, such as the use of hot water heaters in the bathroom, 2.5 mm square wire is far from enough. Therefore, it is imperative to communicate with the hydropower designer when reconstructing the circuit. Carefully consider the power needs of family members.
Some points to note in the renovation of old homes
Everyone has a different understanding of the home, how can we use the limited funds to decorate the perfect home
1, aging water pipes must be replaced
The existing waterway pipelines of second-hand housing often have many unreasonable layouts. During the renovation, the original waterway must be thoroughly inspected to see if it is rusted or aged. Lanzhou decoration experts recommend against everyone: If the original pipeline uses a galvanized pipe that has already been eliminated, it must be replaced with a copper pipe, an aluminum-plastic composite pipe or a PP-R pipe during construction. For example, before decorating the bathroom, first stop the floor drain, put water about 5 centimeters deep and test it. If it leaks, you must redo the waterproof work. At the same time, it should be noted that no dead corner can be left after construction.
2, circuit non-transformation is not
In the second-hand housing, there are widespread phenomena such as simple circuit distribution, aging of wires, illegal wiring, and so on, which can no longer meet the demand of modern households for electricity use. Therefore, it must be completely rebuilt and re-wiring during renovation. If it is found that the original line is an aluminum wire, it must be replaced with a 2.5 mm square section of copper wire. For the installation of high-power electrical appliances such as air-conditioning lines, it should be set up a separate 4 square mm section of the line, and must be used when pvc insulated wire protection pipe.
3, "hidden project" to open again
At present, a large part of the quality problems in home decoration is caused by the improper construction of “hidden projectsâ€. What is the “hidden projectâ€? In the construction process sequence, the work of the previous process is over, and the area that will be covered by the next one that cannot be inspected is called the “hidden projectâ€. Lanzhou decoration experts suggest that we should pay special attention to “hidden projects†when second-hand houses are renovated.
4, the three "face" transformation is essential
In the renovation of second-hand housing, the renovation of walls, floors, and ceilings is the most easily overlooked. Lanzhou decoration experts recommend that professionals are invited to conduct field surveys of the houses to see if there are any obvious cracks, whether they are flat, there are no shedding, and sand. If these conditions exist, repairs must be carried out, including the removal of wall-fouling, powdered wall paints, etc., and the use of cement mortar to repair foundations, cracks, and holes. In addition, the primer should be covered with a primer after the repair, so that the base layer can be firmly secured. Secondly, changes in the base layer due to efflorescence and moisture can be prevented in the future, and then the latex can be diluted with a proportional dilution. During the construction, attention shall be paid to the cleanliness of the air at the scene, and dust protection shall be provided. The tool shall be free of debris.
5, consider the door and window update
Aging doors and windows is also a prominent issue in second-hand housing, but if the material is strong, and you also like its style, in general, as long as the repainting can be a new look, but if the following problems arise, you must remove the redo, the main The question depends on whether the wooden doors and windows are skinned and deformed. If so, it indicates that the characteristics of the wood itself have changed and must be replaced. In addition, the surface of steel doors and windows falling off, the main body rust or cracking, in addition to unsafe, it is difficult to restore the original state, in order to not affect the use of results, experts suggest that should be removed to redo.
6, second-hand housing to be completely disinfected
Before the renovation of the second-hand housing, a 24-hour to 48-hour water storage leak test should be performed on the bathroom and the kitchen to check how the original waterproofing project is done. If there is no leakage, it proves that the waterproofing is done well; if there is water leakage The phenomenon must be re-waterproof. After the waterproof treatment is finished, wait for the ground to completely dry out, then lay the tiles and perform the overall renovation. Moreover, when the toilet is changed, the waterproof treatment of the position of the toilet should be done well. When designing and decorating the top of the toilet, attention should be paid to convenient disassembly, which will facilitate future inspection and maintenance.
7. When dismantling old tiles, pay attention to three points:
(1) When crushing wall tiles and floor tiles, avoid clogging of sewers with debris;
(2) Deal with waterproofing. Use as little elbow as possible to avoid water flow or blockage.
(3) Minimize the use of wood plates, most wood products contain formaldehyde, affect health.
