There is a saying called "do not break without legislation," used in second-hand housing renovation also listen to the right. Second-hand housing renovation is different from new homes. In the decoration, it is necessary to judge the accuracy, the deletion of the changes, and there can be no "improvement" of the idea, especially for some of the relatively high safety performance requirements, such as hydropower reform. Second-hand housing renovation, the most essential requirement is to ensure the quality of decoration, with this foundation to better save money and realize ideas. This article lists seven major items for second-hand house decoration, and each one must be taken seriously.
First, the waterway project can not relax
The waterway must be thoroughly inspected. If there is a water pipe aging, it must be replaced immediately, and the layout of the water pipe is also reasonable. 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 and assembly, which will facilitate future inspection and maintenance. At the same time, it should be noted that no dead corner can be left after construction.
Second, circuit transformation can not be ignored
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. In addition, the new national standard stipulates that the number of fixed sockets in civilian houses should not be less than 12, but there are still many existing second-hand housing outlets that do not meet this standard, if a large number of mobile sockets are used, when the current load When it is increased, the mobile socket will cause abnormally high temperatures due to poor contact, thus burying hidden dangers for electric shock and electrical fire accidents.
Third, "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 a "hidden project"? In the construction process sequence, the work of the previous process is over, and the site that will be covered by the next one and cannot be inspected is called a "hidden project." 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.
Fourth, three "face" transformation is essential
At the time of renovation, renovation of the wall, floor and ceiling of the second-hand house is also very important. Experts suggest that it is advisable for professionals to conduct on-site inspections of the houses to see if there are any obvious cracks, whether they are smooth, free from falling off and sanding. 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.
Fifth, carefully consider the update of 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.
Six, pay attention to three points when dismantling the decoration
1. When smashing wall tiles and floor tiles, avoid clogging the sewers with debris;
2, handle the waterproof, waterway use elbow as little as possible to avoid poor or blocked flow;
3. Minimize the use of wooden boards. Most wooden products contain formaldehyde, which affects health. In addition, the wood will be deformed due to the weather, and the manual cost of wood products is also higher.
Seven, second-hand housing to be completely disinfected
Renovating a second-hand house is an essential step that must be thoroughly disinfected. It can be sprayed with 3% lyosol, 1%-3% bleach water, or 3% peroxy acetic acid solution. Sprinkle doors and windows 1 hour after spilling.
