1. Closed water test for the restroom
Before decorating a second-hand house, first of all, the decoration worker should be asked to perform a water-removal test for the restroom, and check how the previous water-repellent treatment is done. The method is: block the floor drain, put 5CM of water in the toilet, observe for 24 hours, and then go to the neighbors downstairs to check, if there is no leakage, prove that the waterproof treatment is done well; if it leaks, we must ask the property to re-waterproof After finishing the waterproof treatment, wait until the ground is completely dry and then paste the tiles, otherwise the ground will crack.
2. Treatment of water circuit renovation
Water circuit transformation is one of the most complex projects for the transformation of old houses. Before the renovation, we must carefully check whether the original waterway and heating pipeline are rusted and aged. The old house's water supply pipe may be a galvanized pipe that has already been eliminated. Because the galvanized pipe is harmful to human health, it has been banned by the Ministry of Construction. If the original pipe is a galvanized pipe, it is better to replace it with a copper pipe or aluminum-plastic composite. Tube or pp-r tube. Nowadays, waterway reconstruction, people use more is a 50-year quality assurance Nikko. After all the waterway transformations have been completed, it is necessary to make the pipelines reasonable, connect tightly, run without leakage, and move without violation. As for the transformation of the circuit, if the old house is made of aluminum wire, it must be demolished. Modern home appliances are many. According to national standards, 2.5 mm copper wire must be used in the decoration, and the circuit for installing high-power electrical appliances such as air conditioners should be separate. Take a 4mm2 line all the way. PVC insulated pipe must be used when embedding in the wall.

The walls of the old house will be cracked and peeled. Therefore, when decorating the wall, be sure to pay attention to the basic treatment. Generally, a good decoration company will apply the interface agent and interface agent after leveling the wall. With the role of moisture, but also can play a role in the protection of latex paint, followed by putty, putty paste to use waterproof putty, putty scraping generally have to be three times, and finally brush latex paint. If the wall is to be colored, paint it accordingly.

Wooden doors and windows, if there is no deformation or cracking, indicating that the material is very good, can be decorated in the decoration, affixed to the veneer plate, and then painted with paint, continue to use; if the wooden doors and windows have been deformed, then it will be demolished, re-production. Iron doors and windows, if the surface of the paint has been peeled off or the main body cracking, it is recommended that everyone remove, replaced by aluminum or plastic material. Because the doors and windows of these two materials can play a role in sealing, sound insulation and heat insulation.
5, increase the essential switch and socket
Nowadays, as more and more appliances are used in homes, lighting and lighting equipment are becoming more and more colorful, so there are many places where switches and sockets need to be placed. Well, before the renovation, we must do a good job of wiring in advance, which places need to be placed in the future, to do a good job in advance planning, and the old house reserved switches and sockets are generally not enough. In general, a room must have at least 3 outlets. There should be no fewer than 15 sockets in a two-bedroom residential building and no less than 8 switches. The switch height of the same room should be the same, the general switch is 1.4 meters from the ground, and the outlet is 0.3 meters from the ground.
