Lively festivals are coming, but if the water is improperly handled, water leaks, water accumulation, and mildew on the walls will greatly damage the mood of the festival and bring economic losses to the family and neighbors. Home improvement waterproofing is one of the important aspects of decoration, and its quality directly affects the “water problem†after the stay.
Most of the renovation of new homes will require hydropower renovation, which will destroy the waterproof layer made by the developers. In the second renovation, consumers often need to re-lay the floor tiles in the bathroom, which will also cause damage to the original waterproof layer.
Xu Meng, manager of Dongfang Yuhong Marketing Department, said that the cost of waterproofing is not much, that is, using the best waterproof materials, please use the most skilled workers. The current market price is about 60 yuan-100 yuan per square meter, which only accounts for the overall decoration. About 1% of the cost. If it is not waterproof, if there is a leak in the bathroom and the kitchen, water will leak into the downstairs in the floor, affecting the neighborhood, which may cause serious property damage and legal disputes. If you refill the waterproof after you check in, the cost is about 3-5 times before the renovation.
Yu Dong, manager of Tiansheng Decoration Engineering Department, believes that waterproof engineering does not directly "see the ceiling" like ceilings, walls and floors. Many owners put most of their energy into the design, blindly pursuing beauty, but not paying attention to the long-term. Use features. In addition, if inferior waterproof materials are used inadvertently or if they encounter untrained construction workers, the waterproof and leakproof effect of the house is difficult to guarantee.
â– Waterproof details 1. The base layer must be treated before the waterproof construction at home. The base layer must be treated to achieve a smooth, solid, clean, no floating ash and oily surface.
Treatment method: carefully clean the base surface to remove floating dust, and remove cement agglomerates and loose base layer; special treatment is applied to the roots, drainage holes, yin and yang angles, and the voids left after the hydropower reform of the wall surface. After the treatment, use a brush to finely sweep the remaining dust on the base surface, dilute the appropriate amount of waterproof coating to the milk, use the roller to draw the diluted material to the bottom, and then apply the waterproof surface behind the wall to completely remove the dust.
2, brushing should be comprehensive in addition to the bathroom must be waterproof, some families also introduce waterways into the balcony, basement, etc., while the use of floor heating families need to pipe the water on the entire floor, so these It is necessary to waterproof in places that are prone to flooding.
Treatment method: For the buried water pipe in the wall, the groove larger than the pipe diameter should be cut, the groove should be plastered, and the waterproof coating should be brushed. If the original drainage and sewage pipes and floor drains are changed during the renovation, it is necessary to strengthen the waterproof measures in the surrounding area.
3, bathroom waterproof high 1.8 meters general shower or nozzle installed at 180 cm high, if the waterproof is done low, long-term spray caused water to soak the wall, the wall will be mildew, wall decorative coating or tile Peel off, so that it does not get waterproof.
Treatment: Non-shower wall In principle, the waterproof coating should not be lower than 35 cm. However, in order to enhance the waterproof effect, it is recommended that the consumer be uniform to 180 cm. In addition, for lightweight wall and self-built lightweight wall for toilet room renovation, it is recommended to have a waterproof height to achieve the top. Waterproof coatings must be brushed to the national acceptance specification of 1.5 mm thick.
â– Waterproof inspection bathroom to do 24-hour water shut-off test After the hydropower transformation is over, it will be waterproof immediately. To test the effectiveness of the waterproofing, it is mainly through the closed water test.
The water shut-off test is usually carried out after the last time the waterproof coating is applied for 12 hours, after the waterproof coating is firmly combined with the original structure of the base layer. For specific operations, it is necessary to seal the door and the drain. The floor of the bathroom is filled with water to a height of 3-5 cm, and the mark is made. If there is no obvious drop in the water surface within 24 hours, there is no leakage on the roof of the house downstairs. Waterproof is qualified. If the acceptance is unqualified, the waterproof project must be redone and re-inspected.
Lightweight wall can be tested for waterproofing. The waterproofing of the wall should be tested by water spray. The water pipe should be sprayed continuously from top to bottom for 3 minutes on the wall surface of the waterproof coating. After 4 hours, observe the wall. Whether there will be penetration on one side, if there is no penetration, the wall waterproof construction acceptance is considered acceptable.
â– Tips The waterproof layer must be protected. After the waterproof layer is completed, it is necessary to continue to apply the tiling on it. It is often easy to cause damage to the waterproof layer. If the damaged part is not repaired or found, it will cause leakage in the future. Therefore, it is necessary to put on a protective layer.
Usually, the cement is added with the interface agent and then added with a rigid waterproof material to evenly coat. The strength of the mixture is higher than that of the general concrete material, and the rigid waterproof material is added at the same time, so that the waterproof can be foolproof.
The kitchen and balcony are also waterproof. Because when washing vegetables in the kitchen, the kitchen will overflow with water to varying degrees, which will easily cause water to leak along the gap of the floor drain, causing water leakage, so the kitchen also needs to be waterproof. It is generally recommended to turn the kitchen floor and wall up to 30 cm for waterproofing. It is best to turn over 150 cm on the wall where the sink is placed. Because the exposed balcony is exposed to the external environment, it must be waterproofed to prevent water such as rain and snow from seeping downstairs.
