The basic engineering of bathroom decoration, wall and water circuit should pay attention to the construction details to avoid hidden dangers. Beijing News reporter Li Feishe
The humidity of the bathroom is large, the power supply is large, the decoration project should be reasonable, and the purchase of sanitary products should pay more attention to safety.
Compared with other areas where the living room is decorated, the bathroom space has more hidden dangers due to its special environment and moist characteristics. Therefore, in many decoration links and product purchase issues, it is necessary to pay attention to safety and eliminate hidden dangers.
â– Foundation engineering
1 wall new structure to crack
The newly-built wall at the time of decoration requires a firm connection with the original wall when the decoration is completed, and the deformation is small. According to industry insiders, when making structural connections, the wire mesh must be added during surface plastering, which is an effective anti-crack treatment. Then it is best to wait for 7 days before re-construction. At this time, the shrinkage of the new wall is almost the same as that of the old wall, and there will be no delamination and movement in the later stage.
Tip: If the treatment is not strong, cracks between the new wall and the original wall will occur in the later stage. First, waterproofing will be affected, and safety hazards such as falling tiles will occur.
2 waterproof special parts reinforcement
The most important thing about waterproofing is the waterproofing of the bathroom floor and the waterproofing of the shower wall. If the shower room is not the whole shower room, the waterproof between the two walls should be 1.8 meters high. When doing waterproofing, pay attention to the water outlet at the corner of the corner and the bottom of the upper and lower water pipes. The floor drain and the toilet drain are relatively weak parts. The method is to use a non-woven brush waterproof paint to adhere to the weak place, and to strengthen the special part. With the reinforcement treatment, it is possible to effectively prevent the cracks of the base layer from expanding at these portions and prevent the surface of the waterproof layer from cracking.
Tip: Do not make a right angle in the corner of the corner, try to make a corner with a curvature, so that you can effectively avoid the problem that the waterproof layer is thin and the dead angle leaks. Also pay attention to the horizontal brush when applying the waterproof layer. The method of vertical brushing.
3 waterways try to be completely remodeled
There are two methods for waterway reconstruction, one is full renovation and the other is breakpoint transformation. In general, there are more problems in the breakpoint transformation.
Hot and cold welding is required for the connection of new and old pipelines for waterway breakpoints. Generally, the pipes used for waterway reconstruction are mostly PPR pipes. The temperature of the thermal melting point of PPR pipes produced by different manufacturers is different. After a period of use, there may be rupture and water leakage. safe question. Therefore, it is recommended that the renovation of the waterway of the bathroom should be carried out as much as possible to avoid the melting point of the old and new pipes. If it is necessary to break the point, it is best to connect the old and new PPR pipes with joints to prevent safety hazards.
Tip: The water pipes buried in the wall or the ground should not have joints as much as possible. The joint parts should be kept in the parts that can be inspected to prevent problems in time.
4 circuit safety is very important
The bathroom is a heavy area for electricity use at home, so the circuit design is best to go alone. If it is mixed with other circuits, there may be power safety problems when the load is heavy. Appliances with more than 3000W power always require separate circuit control. On the one hand, the safety factor is improved, on the other hand, it is easy to overhaul Any electric appliance that trips due to leakage can quickly find the appliance in question.
The type selection of the leakage protector can't be sloppy. The leakage protector connected to each line needs to be related to the total power of the electrical equipment connected to this line, and cannot be selected at will. According to industry insiders, if the type of the leakage protector is too small, it is prone to short circuit; but it is not easy to be too large, otherwise it will leave a safety hazard, and the electric water heater usually needs 16A.
In terms of construction, if it is old house decoration or secondary decoration, the circuit transformation of the bathroom will be very big, and more matters need to be paid attention to. The most important thing is the adjustment of the line. For example, the wiring of the bathroom should be horizontal and vertical, and the circuit should go from the ceiling, which can greatly improve the safety factor despite the increase of pipeline cost. If the new and old lines are connected, because the degree of aging is different, there may be potential leakage in the joints, so it is recommended to replace all the lines.
Tip: The electrical switch should be installed outside the bathroom as much as possible. The wiring of the bathroom space must be sealed, waterproof and insulated. If there is a socket in the bathroom, keep it away from the water source and add a protective cover. After the water circuit and circuit have been reconstructed, the water circuit diagram should be saved for reference after the problem has occurred.
â– Product selection
5 tiles waterproof and non-slip
The waterproof requirements of the bathroom are very high, so high-quality waterproof wall tiles should be used. The high-density tiles have better waterproof function, which can effectively prevent the surrounding walls from producing mildew and mildew.
Special attention should be paid to the anti-slip of the bathroom floor tiles. Although the brand will present relevant data to consumers when purchasing, it is more appropriate to try to make judgments by stepping on it, and if possible, sprinkle some water and try again. In addition, the anti-slip of the tile is mainly formed by the friction of the contact surface, so try to buy some tiles with patterns and bumps. In addition, if you use polished tiles, be sure to ask if you have added anti-slip agent. You can also feel the anti-slip effect of oysters after water.
Tip: Tile strength determines its resistance to damage. If the strength of the tile is not enough, it will easily lead to the overall cracking of the tile, which may cause the product to fall off and scratch.
6 toilet smart toilet cover leakproof
Many brand smart toilets today have multiple anti-leakage protection devices. When purchasing, pay attention to the manufacturer's product certificate and national safety inspection certificate, and check whether the materials used are materials with flame retardant added.
Many consumers who use ordinary toilets will buy smart toilet seats. However, people in the industry said that all the circuit equipment will be concentrated on this toilet cover, so the smart cover must be bought with good quality, usually pay attention to moisture and waterproof. If you buy a smart toilet that is not of good quality, there may be safety issues such as electric leakage.
Tip: In the bathroom, there are many electrical equipment. Sometimes, although it is designed to be separated from wet and dry, it should also pay attention to good exhaust air. When it is wet, it should be drained in time to prevent water mist from forming, causing the product to be short-circuited due to moisture.
7 shower room chooses high quality tempered glass
Generally, the overall shock and impact resistance of the tempered glass in the shower room will pass the impact test at the factory, and it will be placed for one to two months after the test to process the shower room. However, industry insiders said that when tempered glass is not impacted by external forces, it is most likely to be broken within one month after production. Touching and pressing the tempered glass after the burst will also cause harm to the human body. Experts say that tempered glass with glue or silk can be purchased.
Tip: There are elderly people in the family who should pay special attention to anti-slip measures. They can be installed in the shower room with convenient armrests or sitting positions to facilitate the elderly to pick up or rest. For elderly people with poor health, long-term showers may have "bathroom syndrome" (hypoxia-ischemia due to high temperature and high humidity). The industry recommends that consumers buy a whole bath with ventilation equipment. room.
