Lively festivals are coming soon, but if improperly treated due to water repellent, leaking water, stagnant water, mildew on the walls, etc. will be caused in the bathroom, it will greatly damage the festive mood, and it will also bring economic losses to the family and its neighbors. Home improvement waterproofing is one of the important links in the decoration, and its quality directly affects the 'flooding' problem after the stay.
Most new house renovations will require hydropower reforms, which will destroy the waterproof layer that developers have made. In the second renovation, consumers often need to re-lay the bathroom floor tiles, 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, the best waterproof material is used, and the most skilled workers are required to do it. The current market price is about 60 yuan to 100 yuan per square meter, only accounting for the overall renovation. About 1% of the cost. If water is not sparse, if there is water leaking in one place in the bathroom and the kitchen, it will form a string of water inside the floor and seep into the downstairs, affecting the relations between the neighbors. Seriously, it may cause major property damage and legal disputes. If you refill the water after your stay, the cost is about 3-5 times before the renovation.
Tian Sheng Decoration Engineering Manager Yu Dong believes that waterproof projects are not as direct as the ceilings, walls, and floors, and many owners put most of their energy on design, blindly pursuing their beauty, but do not pay attention to the long-term. Use features. In addition, if a poor quality waterproof material is used inadvertently or if a construction worker without professional training is encountered, the waterproof and leakproof effect of the house can hardly be guaranteed.
â– Waterproof details
1 base treatment
Before waterproof construction at home is installed, the grass roots must be treated to achieve a smooth, solid, clean surface without floating ash and oil.
Treatment method: Carefully clean the base surface to remove floating dust, remove cement agglomerates and loosen the base layer; and perform special treatment on the roots, drainage holes, yin and yang angles, and voids left on the wall after the hydropower reform. After processing, use a brush to sweep the dust on the base surface, dilute the appropriate amount of waterproof paint to milk, and dip the diluted material to the bottom with a roller. Brush the water-repellent surface on the front wall and back wall to completely remove dust.
2 brushing to be comprehensive
In addition to the bathrooms that must be waterproofed, some families have introduced waterways into balconies, basements, etc. during the renovations, while homes that use floor heating need to be piped and walked over the entire floor of the living room. Therefore, these places are prone to flooding. It is necessary to do waterproofing.
Treatment method: For the buried water pipe in the wall, it is necessary to remove the groove larger than the pipe diameter, plaster the groove, and brush the waterproof coating. If the original drainage and sewer pipes and floor drains are changed during the renovation, waterproof measures must be taken in the surrounding area.
3 bathroom waterproof 1.8 meters high
Generally, the shower head or sprinkler is installed around 180 centimeters high. If the waterproofing is done low, the long-term shower will cause the water to saturate the wall, which will make the wall moldy, the wall decoration layer coating or the surface tile peel off, and will not achieve the waterproof effect. .
Treatment method: Non-shower wall can not be less than 35cm in principle waterproof paint. However, in order to enhance the waterproof effect, it is recommended that consumers achieve a uniform height of 180 cm. In addition, it is recommended that the waterproof height be the top for light walls and self-built light walls that have been remodeled in toilets. Waterproof coatings must be brushed to the 1.5mm thickness of the national acceptance specification.
â– Waterproof inspection
The bathroom is closed for 24 hours
After the hydropower reform is completed, waterproofing will be done immediately. To test the waterproof effect is good, it is mainly through the closed water test.
The closed water test is usually carried out after the last time the waterproof coating is applied for 12 hours and the waterproof coating is firmly bonded to the original structure of the base layer. Specific operations need to seal the door and the water outlet, fill the bathroom floor to reach a height of 3-5 cm, and make a mark, if there is no significant decline in the water within 24 hours, especially the roof of the house downstairs did not leak, Waterproof is qualified. If the acceptance fails, the waterproofing project must be redone and re-accepted.
Lightweight wall can be spray test
Waterproof acceptance of lightweight wall should be taken to test watering. The water pipe shall be sprayed on the wall of waterproof paint continuously for 3 minutes from top to bottom. After 4 hours, whether the penetration on the other side of the wall will be observed. , If there is no penetration phenomenon, it can be considered that the wall waterproof construction acceptance.
â– Tips
Damage to waterproof layer must be protected
After the waterproof layer is completed, it is necessary to continue to apply the ceramic tile on the top, which will easily cause the damage of the waterproof layer. If the damaged portion is not repaired or found, it will cause leakage in the future, so it is necessary to apply a protective layer.
The repair is usually made by adding cement to the interface agent and then adding a rigid waterproof material to mix and brush. This kind of mixture has stronger strength than the ordinary concrete material after condensation, and the rigid waterproof material is added at the same time. This kind of waterproofing is perfectly safe.
Kitchen, balcony is also waterproof focus
As the kitchen utensils are washed, the kitchen utensils will overflow with water in different degrees, which will easily cause the water to leak along the gaps in the floor drain and cause water leakage. Therefore, the kitchen needs waterproof protection. It is generally recommended that the kitchen floor and wall are turned 30 cm above the floor for waterproofing, and 150 cm above the wall placed in the sink to set the waterproof layer. Exposed balconies must be waterproofed in order to be exposed to the external environment, so as to prevent rain and snow from seeping downstairs.
