Second-hand housing and new home renovation is different, due to factors in all aspects of age, there are too many places to pay attention to the decoration, if you do not pay attention, it is easy to bring inconvenience to the future of home life, today Xiao Bian gave you talk about second-hand housing Things to know about decoration!
First, the aging water pipe 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. If the original pipeline uses a galvanized pipe that has been eliminated, it must be replaced by 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.
Second-hand housing generally has the phenomenon of simple circuit distribution, aging of electric wires, illegal wiring, and so on, which can no longer meet the electricity demand of modern households. Therefore, it must be completely rebuilt and rewired during the renovation. If it is found that the original line is made of aluminum wire, it must be replaced with a 2.5mm square section of copper wire. For the installation of air-conditioning and other high-power appliances, a 4 mm square section of the line should be set up separately, and a PVC insulated conduit should be used when embedding.
Third, the "hidden project" was opened again
At present, a large part of the quality problems in home decoration is caused by the improper construction of “hidden projectsâ€. What is "hidden project"? In the construction process sequence, the work of the previous process is over, and the area that will be covered by the next one and cannot be inspected is called a “hidden projectâ€. Therefore, in the second-hand housing renovation, we must pay special attention to "hidden projects." For example, whether the pipelines, lines, and equipment of various facilities such as water supply, air conditioning, and ventilation in the ceiling have been subjected to closed tests and electrical insulation and resistance tests, whether the connection is firm, whether the joint practices meet the requirements, and whether the flammable materials have been fire-resistant. Combustion treatment and so on are all within the scope of “hidden projects†and are no longer inspectable after the first installation. Industry insiders suggest that when the old house is renovated, it is a good opportunity to eliminate hidden dangers by reopening these parts. The landlord must strictly inspect and remove the "hidden project" left over from the past.
The fourth and third “face†transformations are indispensable
During renovation, renovation of the wall, floor and ceiling of second-hand housing is the most easily overlooked. Experts suggest that it is best for professionals to conduct field surveys of the houses to see if there are any obvious cracks, if they are flat, there is no shedding, and there is 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.
Fifth, careful consideration of windows and doors updates
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.
Sixth, second-hand housing to be completely disinfected
After the renovation is completed, after the demolition work is completed, all debris should be cleaned and then no details of the room should be disinfected. Followed by the construction of the follow-up.
Seventh, pay attention to three points when dismantling old tiles
1. When smashing wall tiles and floor tiles, avoid clogging the sewers with debris;
2, handle the waterproof, the waterway to use as little elbow, to avoid poor water flow or plugging.
3. Minimize the use of wooden boards. Most wood products contain formaldehyde and affect health.
