â– Fourth, the basic treatment of the wall if it is the original corner, the wall of the reasons, should promptly notify the relevant departments to deal with. In addition, before the wall is painted, the original wall must be shovelled and dirt must not be left.
â– Five, heating, gas transformation of heating transformation If the company needs to be replaced, must be agreed by the relevant departments and owners. Need to reform the heating pipe,
The upper and lower water should be added with valves. The valves should be closely connected and there should be no leakage. After the heating and the pipeline are completed, pressure tests are carried out.
The waterproof layer should be subjected to a 24-hour leak-proof test. â– Sixth, waterproof project The waterproof coating that sells on the market at present generally is divided into: Asphalt waterproof coating, polyurethane waterproof coating, acrylic acid type waterproof coating. On the other hand, waterproof coatings are divided into two types, oily and waterborne. Polyurethanes are oil-based waterproof coatings, and their prices are relatively low, but they are slightly inferior to water-based waterproof coatings in environmental protection, efficacy, and ease of construction. In construction, waterproofing also needs to pay attention to the thickness of the waterproof layer to reach: generally 1.5-2 mm. If there are special requirements, the waterproof height can be up to 1.8 meters from the ground. Waterproofing must be done 24-48 hours of closed water experiments.
Home decoration hidden project pay more attention With the increasingly hot home decoration, decoration problems are more and more, in these decoration quality problems, "concealed project" accounted for a large proportion.

"Hidden project", the most common explanation at present is that during the renovation process, concealing the pipeline engineering and structural engineering inside the decorative surface, and the construction project whose surface cannot be visually seen. In home decoration, the “hidden project†is the most easily overlooked and is generally divided into: waterway reconstruction, circuit reconstruction, heating reform, gas transformation, and the treatment of the suspended ceiling wall. ■First, waterway renovation Home renovation, the main waterway is not the most common waterway transformation is the "concealed project", all the water pipes in the living room to maintain the patency of the pipeline. If you want to change the upper and lower water pipelines, you must greet the property management department, and you should also ask the professionals to design the pipelines for construction. When the waterway is reformed, a PPR hot water pipe is usually used. Its purpose is to prevent the cold water pipe from bursting. ■Second, the transformation of the circuit The current room is buried with buried lines, so the owner is not easy to check the construction. According to regulations, the wire trough must be level and vertical on the wall. The construction personnel shall determine the installation position of the cassette on the wall surface. The general requirement for the depth of the trough is 2 times that of the used wire tube, and the height of the cassette should be the same. The buried lines cannot be buried directly in the plastering layer but must be sheathed outside the wires. Wires in the bushing must not be twisted or jointed. In the installation of the line, it is necessary to remember left-right and right-fire and connect it to the ground. ■III. Concealed ceilings Generally, ceilings use wooden keels or light steel keels. Similarly, concealment works are also very important. To use wood keel ceilings, fireproof paint should be brushed 1-2 times. Because wood keels are easily distorted, light steel keels are now commonly used. However, it should not be directly fixed by air nails, and the horizontal deviation must not exceed 5 mm.
