How to identify the quality of the home decorating project? It can be said that it is more difficult, especially the current decoration market is not very normative, but it is also the two sides of the A and B executives. As the home decorating is mainly manual operation, the technical level, construction period and construction season of construction workers will affect the actual project quality. Therefore, in terms of judging standards, there must be a certain degree of flexibility, do not over-indulgence, but it cannot be overemphasized. Too picky. In addition to the quality standards that can be clearly stated on the decoration contract, there are certain deviations that must be allowed in other aspects, as long as it does not affect the overall structural safety, does not affect the specific use of functions, does not affect the appearance, even if it can be qualified. The following describes several methods for users to refer to, but to declare: This is not the standard issued by the state, does not have legal effects, but some of the views of some professionals, can not be used as the only criterion for the actual identification. 1. Ceiling and top brushing 1) Based on the design elevation of the ceiling, ±5mm is allowed on the horizontal plane. 2) The galvanized iron wire used for the hanging bar must not be smaller than No. 8 and the expansion bolt must be used as the hanging point. 3) If wooden keel is used, the material must be red and white pine without cracking or distortion.

The distance shall be more than one meter away from the wall surface, and obvious joints shall not be exposed. 6) The arrangement of non-complete bricks should be appropriate. The size of the bricks cut around the wall protrusions (such as sealing pipes, etc.) must be accurate and the edges must be consistent. 7) Tiles (face tiles) should be firmly affixed without hollowing or chromatic aberration, and should not be skewed, lacking corners, and edges and cracks. 8) The height of the joints can have a deviation of 5mm. In addition, the surface is flat and the vertical surface can also be allowed to deviate by 2mm. 3, plate floor and wooden floor 1) commonly used floor panel block: marble, granite, ceramic floor tiles, are using cement (mixed yellow sand, and some are also mixed with glue) paving, a large area of ​​ground material surface finish, texture , patterns, colors should remain uniform and consistent, no color. 2) The surface layer and the bottom layer must be completely adhered firmly, and no hollow sound can be knocked on.

The deviation of verticality shall also be within 2mm. The specific inspection can be checked with a line hammer. In brief: horizontal Vertical is the criterion. 3) The surface of the siding should be smooth and smooth. If the pattern is made, the width of the meticulous wood should be the same and close to the siding. In addition, there should be no hammer marks, no pollution, no nail caps, and edges and corners should be straight. 4) The joints of doors and windows, hanging mirrors, and curtain boxes should be tightly jointed. They must be docked at an angle of 45 degrees, and they should be close to the wall surface.

(As the saying goes: paint is confused and paint is covered. Hundred ugly). 5, the water supply and drainage pipes, sanitary ware 1) The installation of the pipeline should also be horizontal and vertical, the pipeline is unobstructed, the installation position of various types of valves is reasonable, easy for future maintenance and replacement. 2) If it is used as a concealed pipe, water and pressure shall be used after completion to check if there are any seepage or water leakage in all joints, valves and connection points. 3) Sanitary fixtures need to be installed after the ceiling is suspended (if ceilings are required), the water supply and drainage pipes for baths, toilets, water tanks, and washbasins should be installed reasonably.

If there is a lot of high-power household appliances in a certain room, it is better to use a line with more than 4 square meters. 3) The power cord, telephone line and cable line must not be worn in the same jacket. Safety concealed sockets and concealed switches should be used. It is best to install a leakage protector. The heads of various types of junction boxes shall be reserved for more than 15 cm. Before the wall is closed, the power supply must be checked carefully.
