How to Accept Acceptance of Home Improvement Projects

When accepting the acceptance, the owner must focus on checking the non-compliance of the decoration due to high temperature, humidity and the time of work and material loss.

Wood product foaming deformation

In the hot and humid summer, the key to renovation is moisture protection. If the moisture-proof work is not handled well, in the dry season, wood and boards will be easily deformed and lifted. Therefore, the acceptance of woodwork is more important in summer decoration.

Key acceptance: After the door cover absorbs moisture, it is generally reflected in the bottom, and there will be blistering, bloating and deformation of the paint. If the door sleeve only swells, the gap between the door frame becomes larger and it can be resealed with glass glue. If the door sleeve is seriously deformed and affects the normal opening and closing of the door, the door sleeve must be replaced again. If it is lacquer blistering, you need to polish the door sleeve and paint again.

Other acceptance: whether the woodwork is straight, the surface is smooth, there is no drum or breakage. Whether the door switch is normal or not should be operated lightly and without any noise; the fixed wall of the cabinet should generally have no gap. Liners and panels must be firmly bonded.

â—Ž Tips: After wood products rain in the rainy season, there will be foaming deformation. If wooden products are used on the sill, check carefully whether there is stagnant water penetrating under the sill through wood or its gap with the wall.

Loose floor keel

When paving the floor, the gap should be arranged more closely than before to avoid the gap becoming larger when the temperature decreases and affecting the appearance.

Key acceptance: When passing the inspection, walk around on the floor, especially in the area of ​​the wall and the door hole, pay more attention to the acceptance, find the site with sound, and repeat the movement to determine the specific location of the sound and make a mark. In this case, you can ask to remove the resurfacing. The site of sound is mainly reflected in the unstable fixation of the keel. Some decoration construction units use the untreated keel construction. The surface shows signs of drying. In fact, it did not dry. The keel with high moisture content will shrink in volume during the natural drying of the wood, causing looseness.

â—Ž Tip: Solid wood flooring first depends on whether the floor color is the same. If the color difference is too large, it will directly affect the appearance and can be exchanged. Whether the floor is deformed or warped, the acceptance method is to use a 2 meter long ruler, leaning on the floor, the flatness should not exceed 3 mm.

Tile empty color change

Key acceptance: Check the tiles to see if there are empty drums. If there are too many empty drums, they will be gradually crushed after long-term use, which will affect the appearance and affect the use. Hollow tiles are mainly due to too much water in the cement mortar on the paving tiles. After a few days, the moisture in the cement mortar will volatilize, and the mortar below the tiles will fall and the tiles will empty.

Check if the tiles are discolored. If the tiles are found to be discolored, in addition to the poor quality of the tiles and the thin shaft surface, improper construction methods are also important factors. It is possible that there is a problem with the water that is used to soak tiles during construction, or that the cement mortar used for tiling is not good, and the wall tiles that have a larger change of color must be immediately renewed.

Other acceptance: acceptance depends on whether the brick surface is flat, there is no tilt, whether the brick surface is broken, whether the tile direction is correct, tile and waist position is correct, the general local hollowing shall not exceed 5% of the total.

â—Ž Tip: Keep the gap as small as possible during the rainy season, because it has a certain degree of expansion, and it can shrink during the dry season.

Cracked wall

There is a large temperature difference in summer and winter, and if the decoration is not careful, there will be gaps and other situations.

Key acceptance: Summer paints often run dry and will mold in wet weather. The moldy wall comes from two aspects. First, the wall surface is damp and moldy. Second, when puttying is not done, it can be caused by the dry putty of the brush. The cracking on the Beijing wall is a normal phenomenon. The main reason is that the joints between the indoor thermal insulation board and the thermal insulation board will cause cracks in the board seams, shrinkage cracks and plasters appearing after the grooving of the wire troughs in the walls where the wires and cables are laid. Squeezed putty uneven stress cracks.

Other acceptance: Wall latex paint has no hollowing, blistering, cracking phenomenon. General latex paint is strictly prohibited peeling, leaking brush, through the bottom, large surface without falling, wrinkled skin, the surface color requirements, no obvious brush marks.

â—Ž Tip: The most common phenomenon is the appearance of cracks on the wall surface of the renovation construction. It may not be visible just after renovation. This is particularly evident during seasonal climate changes. This requires the company's late-stage maintenance and repairs.

Paint white

Focus on acceptance: Furniture should be carefully examined to see if there is a phenomenon of white fogging. This is caused by the rain paint. The surface of wood products will gather a layer of water vapor in the rainy day. At this time, paint is applied, and water vapor is trapped in the paint film, making the surface of wood products cloudy and unclear. If the varnish is applied on a rainy day, whitening may occur.

Other acceptance: whether the surface of furniture mixed oil is satisfactorily saturated in the inspection of the paint, ensuring that there is no foaming, no cracks, and that the thickness of the paint is balanced and uniform. The quality of painting of wooden furniture is usually to see whether it has chromatic aberration and drop phenomenon, the surface should be clear and smooth, there is no pungent odor.

â—Ž Hints: Paint should be painted to avoid paint on rainy days. If it is not rainy, when it is painted in an especially humid environment, use desiccant or air conditioning to dehumidify the air. After the wall is finished, the cabinet against the wall immediately will cause the cabinet to get wet.

Doing Edge Sealing to Prevent Pollution

When the temperature rises and the humidity increases, the decoration materials become more and more polluted. During the construction process in the summer, more VOCs (volatile and toxic compounds) will be emitted from the construction site than in the winter. Therefore, the indoor decoration pollution in the summer is even more serious. The distribution of the harmful gas is a long-term process, and there are even some Pollution sources continue to be distributed within fifteen years. Benzene is emitted in half a year, but it may take more than 10 years for formaldehyde to be completely emitted from plastic.

Key acceptance: It must be carefully checked whether the plate is well-sealed. All the edge seals require the use of seal lines to seal off the free formaldehyde. Custom furniture often needs to be laminated, and the inside of the laminate will be drilled. This is the hole that emits formaldehyde. It should be provided with a “cap” at the hole to close the hole.

â—Ž Tip: It is inevitable that there will be some poisonous and harmful gases in the decoration. After the renovation is completed, we must pay attention to the ventilation of more windows every day. After the renovation, the owner can ask a professional agency to test the indoor environment. Once decoration and environmental protection are not up to standard, the decoration company will not be able to carry out inspection and acceptance of the project.

â–  Acceptance details

Drainage pipeline should be unimpeded

Bathroom cold and hot water switches, faucets and showers are installed in a flat and flexible manner. Check if the water flow changes with the size of the water festival door opening. There is no blockage in the floor drain. Drainage pipelines should be open, no backslope, no clogging, no leakage, floor drains should be slightly lower than the ground. Check and discharge the water after filling and check whether the drainage is smooth.

The floor of the kitchen and toilet, which is in contact with the wall around the floor waterproofing layer, should be turned upwards and not less than 250 mm above the ground. The surface water layer of the ground surface drains to the floor drain, and the pan water or water is not poured. The 24-hour storage test has no leakage.

Repeated test light switch

The electricity should be checked and tested as necessary, such as lighting test, switch test control, repeated switching several times, to observe whether the lights are all on. The switch socket panel shall be securely installed, in the correct position, with a correct cover, a smooth surface, and close to the wall with no gaps around. The height of the switch or socket in the same room should be the same. When the project is completed, it is required to ask the construction unit for a schematic drawing of the wiring, indicating the wire size and the direction of the pipe.
