"Sensitive area" decoration needs care
According to the Tianheng Chengxin Home Decoration Technical Service Center under the Beijing Building Decoration Association's Home Improvement Committee, the most prone to problems in home decoration is the waterproofing of all wood products, latex paint walls and toilets. Due to these three problems, the quality disputes caused by home decoration account for more than 80% of the total number of decoration complaints.
Therefore, when you are doing home renovation during the spring season, pay special attention to the “sensitive areas†of these home improvement. Especially in the selection of materials and construction, you must be extra careful to avoid quality problems.
In order to prevent quality problems in the "sensitive areas" of home improvement projects, we have specially prepared a set of related articles for you, I hope to help you.
Leakage in the bathroom: strict prevention and attention to the corners
Many families in the renovation must destroy the original bathroom wall tiles and lay new tiles. The result of this is that it is necessary to re-waterproof the wall of the bathroom. If there is a quality problem in the waterproofing project, the water stain will fall into the next room, and the heavy leak will fall downstairs, causing serious damage to your home and neighbors.
At present, there are many kinds of materials for waterproofing the bathroom, and basically the waterproof effect is good. But you have to pay attention to the specific construction details.
1. The bathroom floor should be leveled first. If you want to replace the floor tiles of the bathroom, after you have cut the original floor tiles, you must first level the floor with cement mortar and then do waterproofing. This can prevent leakage of the waterproof coating due to uneven thickness.
2. The seams should be painted in place. The seam between the bathroom wall and the joint between the upper and lower water pipes and the ground is the most prone to problems. During the construction, you must urge the workers to handle these corners and corners. All waterproof coatings must be applied "in place".
3. Wall treatment is also very important. In the general bathroom waterproofing treatment, the wall surface should also be made of waterproof coating of about 30 cm high to prevent water from oozing through the wall. However, if the wall of the bathroom is a non-load-bearing light-weight wall, the entire wall should be covered with waterproof coating. If your home uses a two-piece shower screen, the associated two walls should also be fully painted. If your home uses a bathtub, the wall adjacent to the bathtub, the height of the waterproof coating is also higher than the upper edge of the bathtub.
4. Waterproof experiments must be done. After the construction of the bathroom is completed, all the water in the bathroom will be blocked, and a 25 cm high "can" will be built at the door, and then 20 cm of water will be poured into the bathroom. After 24 hours, you will check the surrounding walls and the ground for leaks. This 24-hour waterproof test is the key to ensuring the quality of the bathroom waterproofing project. You must do it.
5. Keep the water flowing smoothly. All sewer pipes in the bathroom, including floor drains, plumbing pipes for sanitary ware, etc., should be kept open. In this way, we can fundamentally avoid the occurrence of the "Scouted Seven Army" tragedy. Jin Yi, general manager of Yihe Boutique Home Improvement Market
Wood deformation: the most important thing to keep moisture content stable
At present, many families use wood products in the decoration, such as curtain boxes, heating covers, fixed furniture, wooden lines and door and window covers. However, once the temperature and humidity in the room change greatly, some wood products will have problems such as cracking, warping and deformation. In fact, many of the quality problems of home decoration are in the moisture content of wood products.
Whether it is solid wood or artificial board, all wood products contain a certain amount of moisture. Many consumers think that the dryer the wood, the better. In fact, this view is biased. The moisture content of the wood can only be maintained within the normal range to ensure that the quality of the decoration does not occur. For wood materials used in general households, the moisture content should be around 8%. If the moisture content is too high or too low, it will cause quality problems in the wood in the home decoration.
In order to keep the moisture content of the wood stable, you should pay attention to the following points in the decoration:
1. Use artificial boards
The texture properties of various artificial boards are much more stable than solid wood materials. Since the solid wood material has texture, when the temperature and humidity change greatly, cracking, warping and deformation will inevitably occur. The wood-based panel is used to break down the wood into wood chips or wood pulp, and then re-form the wood. Because the original physical structure of the wood is broken, the "deformation" of the artificial board is much smaller than that of the solid wood when the temperature and humidity change greatly.
2. Construction attention detail
In the home decoration, the key to the quality of wood is construction, especially the details:
â— Apply all paint immediately after installation. This layer of paint, called "top coat", not only protects wood products, but also protects against moisture and maintains the normal moisture content of the wood;
â— Do not drown in the adhesive. At present, in the home decoration, white latex is generally used as a binder for wood products. Some workers exchange water in white latex in order to cut corners. This not only reduces the strength of the binder, but also causes quality problems when the wood product absorbs moisture;
â— All wood should be placed for a few days. After you buy the wood for decoration, it is best to put it in the decoration site for a few days before using it. The purpose of this is to make the moisture content of the wood close to the level of the new home.
3. Be careful when buying materials
When you purchase wood for decoration, it is impossible to determine the moisture content of the wood by eye or hand touch. Therefore, some people lamented: If only by visual inspection, the moisture content of wood can be described as "the fairy is difficult to distinguish." In fact, there are some tips to help you determine if the moisture content of the wood is acceptable. Generally, the characteristics of dry wood are obvious, the weight is obviously reduced, the hand feel is not cool, the tapping is crisp, the “squeaky†sounds when the planer is pushed, the shavings are heated, and the surface is light. The wood with high water content is heavier, feels cold, and is not brittle when pushing the plane, even shaving. This type of wood cannot be used. Pine
Cracking of the insulation wall: a lot of methods are cleverly adopted
At present, in many new houses, there are new insulation walls with insulation layers. This kind of wall is prone to cracking of latex paint during decoration. In fact, this cracking is caused by cracks in the cement of the wall or cracks in the joints of the "insulation board" of the wall. It is not a quality problem of the decoration, but an insurmountable defect in the building.
In order to pursue the best decorative effect and use decoration to make up for the building defects, the decoration company's technicians have come up with many ways to deal with the cracks in the insulation wall. You can choose according to your own actual situation and renovation budget:
1. After the wall substrate is cleaned, a layer of good cloth, kraft paper or newspaper is applied to the wall to ensure the integrity of the latex paint film. This method is relatively simple and easy, but the effect is average.
2. Remove the insulation board on the wall surface, or remove the cement wall surface, install a layer of gypsum board or “five PCT board†on the outside of the insulation layer, and then make latex paint on it. This method can remove all the irregular cracks, and the cracks are generally the joints between the plates, which is better to handle. However, this method is costly and difficult to construct.
3. Made of elastic decorative material. At present, in the treatment of wall substrate, there is a kind of "elastic putty" which can compensate for the wall crack problem to some extent. Nippon Paint's "three in one" can also play a role in covering small cracks on the wall. But the material itself has less "elasticity" and does not work on walls with cracks.
In addition, some consumers simply remove the insulation layer of the wall. Although this method can be done once and for all, it will reduce the insulation and thermal insulation of the wall, so it is not recommended.
