The renovation of old houses is more tedious than the renovation of new houses, because the renovation of old houses also involves the dismantlement of previous renovations. Therefore, if you do not know enough about your old house and check in after a hasty renovation, you will find that all kinds of problems have come. For example, problems such as water leakage or wall cracking will often cause you much trouble and regret. Then, with the small series together to understand the professional home renovation precautions.
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, the wall transformation is essential
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.
Third, consider carefully updating windows and doors
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. In addition, it is recommended that consumers in the decoration can consider using a door frame radiator, so that the window frame into a heating, both beautiful and can effectively reduce the indoor and outdoor temperature difference, reduce heat and heat exchange, keep room temperature, reduce energy consumption.
Fourth, the circuit can not be transformed
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 an aluminum wire, it must be replaced with a 2.5 mm 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.
V. "Hidden Projects" Reopened
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, reopening these areas is a good opportunity to eliminate hidden dangers. The owners must strictly inspect and remove the “hidden projects†left over from the past.
Six, second-hand housing to be completely disinfected
Before decorating a second-hand house, a 24-hour to 48-hour water storage leak test should be conducted on the bathroom and kitchen to check how well the original waterproofing project is done. If there is no water leakage, it proves that the waterproof treatment is done well; if there is a leak 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.
