According to the statistics of the Tianheng integrity home improvement technical service center under the home improvement committee of the Beijing Building Decoration Association, the current home renovation is the most prone to problems, that is, all the wood products, latex paint walls and bathroom waterproofing works in the renovation. Due to the problems in these three areas, quality disputes related to home improvement have to account for more than 80% of the total number of decoration complaints.

Therefore, you must pay special attention to these "sensitive areas" in your home improvement period during your home renovation season. Especially in materials selection and construction, you must be especially careful to avoid quality problems.

In order to prevent quality problems in the “sensitive areas” of home improvement projects, we have prepared a set of relevant articles for you, hoping to help you.

Toilet leakage: prevent sticking to the corner

Many families in the renovation have to knock down the original bathroom tiles and lay new tiles. As a result of this, it is necessary to re-waterproof the wall of the bathroom. If there is a quality problem in the waterproofing project, water stains will hit the next room, and if it is heavy, it will leak downstairs, causing serious damage to your home and neighbors.

There are many kinds of materials used for bathroom waterproofing at present, basically the waterproof effect is good. But you should pay attention to the specific construction details.

1. Level the bathroom floor first. If you want to change the floor tiles of the bathroom, you must first level the floor with cement mortar after the original floor tiles are cut, and then do the waterproof treatment. This will prevent leakage of the waterproof coating due to uneven thickness.

2. Joints should be brushed into place. The seams between the bathroom wall and the seams between the upper and lower water pipes and the ground are the most prone to problems. During construction, you must urge the workers to handle these corners. All waterproof paint must be applied in place.

3. Wall treatment is also very important. In the general bathroom waterproofing treatment, a waterproof coating of about 30 cm in height is also required on the wall to prevent water accumulation from passing through the wall. However, if the wall of the bathroom is a non-load-bearing light wall, the entire wall should be covered with a waterproof coating. If your home uses a two-seater shower screen, the two walls that are associated with it must be fully painted. If your home uses a bathtub, the height of the waterproof coating should be higher than the upper edge of the bathtub.

4. Waterproof experiment must be done. After the construction of the bathroom was completed, all the water in the bathroom was blocked, and a 25 cm high “can” was built at the entrance. Then, 20 cm of water was poured into the bathroom. After 24 hours, you can check whether there is any leakage around the wall and the ground. 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 open. All sewers in the bathroom, including floor drains, sanitary ware plumbing, etc., should be kept open. In this way, we can fundamentally avoid the occurrence of the "flooded seven army" tragedy. General Manager Jin Hao of Jardine's boutique home improvement market

Deformation of wood: it is most important to keep the moisture content stable

At present, many families use wood products such as curtain boxes, heating covers, fixed furniture, wooden lines, and door and window covers in large quantities in the decoration. 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 quality problems in home decoration are due to the moisture content of wood products.

Whether it is solid wood material or artificial board, all wood products contain a certain amount of moisture. Many consumers believe that the more dry the wood, the better. In fact, this view is biased. The moisture content of wood can only be maintained within the normal range to ensure that there is no quality problem in the decoration. 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 improvement.

In order to keep the moisture content of the wood stable, you should pay attention to the following points in the decoration:

1. Use more artificial plates

Compared with solid wood materials, the texture properties of various artificial boards are much more stable. Because the solid wood material has a texture, when the temperature and humidity change greatly, cracking, warping, and deformation will inevitably occur. The wood-based panel is to decompose wood into wood chips or wood pulp and re-make the boards. Because the original physical structure of the wood was broken, when the temperature and humidity changed greatly, the "deformation" of the wood-based panel was much smaller than that of the solid wood.

2. Construction attention details

In home decoration, the key to the quality of wood is construction, especially the details:

● Paint all paint immediately after installation. This layer is called "topcoat" paint, not only can protect wood products, but also can play a role in isolating moisture and maintaining the normal moisture content of wood;

● Do not use water in the adhesive. In home decoration, white latex is generally used as a binder for joints of wood products. Some workers dip water in white latex in order to cut corners. This not only reduces the strength of the binder, but also causes the wood product to absorb moisture.

● Keep all the wood for a few days. After you purchase the wood for decoration, it is best to put it on the decoration site for a few days before use. The purpose of doing so is to make the moisture content of wood close to the level of new homes.

3. Beware of purchasing materials

When you purchase wood for decoration, it is impossible to determine the moisture content of the wood with only your eyes and hands. So someone sighed: If you only rely on appearance inspections, the moisture content of wood can be described as “divine and difficult to distinguish”. In fact, there are some tips that can help you determine if the moisture content of the wood is acceptable. The characteristics of dry wood are generally obvious, the weight is significantly reduced, the feel is not cool, the sound of knocking is crisp, the sound of “squeaking” sounds when the planer is pushed, the wood shavings are heated, and the planer is light. The wood material with high moisture content has a heavy body, a cold feel, and is not brittle when pushed by a planer, and even the shavings produce water. This type of wood cannot be used.

Insulation wall cracking: a lot of clever use of methods

At present, in many new houses, there is a new insulation wall with insulation. This type of wall decoration is very vulnerable to the problem of cracking latex paint. In fact, this cracking is caused by cracks in the wall's cement, or the cracking of the wall's "insulation board" joints, not the quality of the decoration, but the architectural insurmountable flaws.

In order to pursue the best decorative effect, using decoration to make up for architectural defects, the decoration company's technicians come up with many ways to deal with the insulation wall cracks. You can choose according to your own actual situation and decoration budget:

1. After the wall surface is cleaned, first apply a layer of Dacron cloth, kraft paper or newspaper on the wall surface, and use the tension of the fiber to ensure the integrity of the latex paint film. This method is relatively simple and easy, but the effect is general.

2. Remove the insulation board on the surface of the wall, or remove the cement wall. Install a layer of gypsum board or “5 PCT board” on the outside of the insulation layer, and then do the latex paint on it. This practice can remove all irregular cracks, cracks are generally the joints between the plates, better handling. However, this method is expensive and difficult to construct.

3. Use a decorative material with elasticity. At present, on the wall surface treatment, there is a kind of “elastic putty” that can make up for the wall crack problem to some extent. Nippon Paint's "three in one" can also play a role in covering the small cracks on the wall. However, these materials have less "elasticity" and do not work on cracked walls.

In addition, some consumers simply remove the wall insulation. Although this method can be used once and for all, it will reduce the insulation and thermal insulation properties of the wall, so it is not recommended.
