In the 21st century, where housing prices are soaring, second-hand housing has become the target of choice for most buyers. However, when second-hand housing is renovated, it is easy to overlook the most hidden dangers. The first and foremost is the hidden dangers of doors and windows.
The first measure: the renovation of the second-hand house before the detection of waterproof engineering
The water storage test should be carried out on the bathroom and kitchen for 24 hours to 48 hours to check the quality of the original waterproof project. If there is water leakage, it must be redone.
The second measure: it is best to disinfect before decorating second-hand housing
The second-hand house should be completely disinfected before the renovation. It can be sprayed with 1%-3% bleach water or 3% peroxyacetic acid solution. After closing, close the door and window for 1 hour.
The third measure: the aging galvanized pipe must be replaced
When the second-hand house is renovated, the original waterway must be thoroughly inspected. The original water pipe route often has many unreasonable layouts to see if it is rusted or aged. If the original pipeline uses a galvanized pipe that has been eliminated, it must be replaced with an aluminum-plastic composite pipe, a copper pipe or a PP-R pipe during construction.
The fourth measure: repairing the base layer and cracks with cement mortar on the wall
Before the decoration, it is best to ask the professional to conduct on-the-spot investigation of the house. If there are obvious cracks, unevenness, falling off and sanding on the wall, the ground and the ceiling, it is necessary to repair it. After repairing, apply a primer to cover it, then re-brush the latex paint.
The fifth measure: aging circuit is a hidden danger, it is best to re-route
Second-hand houses generally have simple circuit distribution, aging of wires, illegal wiring, etc., so they must be completely rebuilt and re-routed during renovation. If the original line is found to be an aluminum wire, it must be replaced with a copper wire of 2.5 square millimeters. For the installation of high-power electrical appliances such as air conditioners, a 4 mm square section of the line should be provided separately, and PVC insulated retaining wire must be used when embedding.
Sixth trick: replacing old doors and windows is the key to second-hand housing renovation
This is the easiest item to be overlooked in the decoration, but for the second-hand house decoration, the aging of the door and window is a prominent problem, which includes multiple problems such as health, safety and theft prevention. However, if the material is sturdy and the style is not outdated, it can be used as long as it is repainted. However, if the wooden door and window are peeled and deformed, the characteristics of the wood itself change. It is not advisable to use new windows and doors.
