Home decoration waterproof is very important, and

  • Detail

Reader Mr. Lin: a few years ago, the rental house at home was simply decorated by the road guerrillas. Recently, the residents reported to me that the water seepage on the floor of the washbasin in the bathroom also affected the residents downstairs. The downstairs asked that they must be responsible for this matter and repair it. I consulted some decorators, who believed that the waterproofing was not done well at the time of decoration. This time, we need to pry the floor tiles open and make waterproofing again to solve the problem. However, such costs and quantities are relatively large. Excuse me, what should we pay attention to when doing waterproof again, or is there a better remedy

home decoration network answer: Master Chen, who has many years of experience as a cement worker, told reporters that waterproof treatment is a key project in toilet decoration, which requires the decoration master to do it conscientiously

the water seepage in Mr. Lin's home is located on the floor of the wash basin. In this case, first check whether the water pipe of the wash basin is in good condition. If it is caused by water leakage, replace the water pipe. If the water seepage disappears after replacement, there is no need to make a waterproof layer again. Otherwise, the waterproof layer should be repaired in time to avoid hidden dangers

if it is necessary to replace the original floor tiles in the bathroom, after chiseling the original floor tiles, be sure to level the ground with cement mortar first, and then do waterproof treatment, so as to avoid leakage caused by uneven thickness of waterproof coating. Before waterproofing, the ground must be cleaned and painted twice or three times with polyurethane waterproof paint

the joints between the wall and the ground and the ground joints of pipes between water supply and drainage are the places where problems are most likely to occur. Workers must be urged to deal with these edges and corners, and waterproof paint must be applied in place. The decoration team is required to do a good job of cement mulch for the upper and lower pipes of the kitchen and bathroom, brush 10 to 20 cm of polyurethane waterproof paint upward from the ground, and then redo the polyurethane waterproof on the ground, add the original waterproof layer, and form a composite waterproof layer to enhance the waterproof property

when bathing in the bathroom, water will splash on the adjacent wall. If there is no protection of the waterproof layer, the adjacent wall and the opposite corner wall are prone to moisture and mildew. Therefore, we must do a good job in wall waterproofing before laying wall tiles. Generally, the wall surface should be waterproof with a height of 30cm in waterproof treatment, but for non load-bearing light wall, the whole wall should be waterproof, at least 1.8m high. If a bathtub is used, the height of the waterproof coating on the wall adjacent to the bathtub should also be higher than the upper edge of the bathtub

after the waterproof project is completed, seal the door and water outlet, fill the toilet floor with water to a certain liquid level, and mark it. If the liquid level does not drop significantly within 24 hours, especially if there is no leakage on the roof of the house downstairs, the waterproof is qualified. If the acceptance is unqualified, the waterproof works must be redone as a whole and then re accepted

for the acceptance of the waterproof construction of the light wall, the water pouring test should be adopted, that is, use the water pipe to spray continuously from top to bottom on the wall with waterproof coating for 3 minutes, and observe whether there will be seepage on the other side of the wall after 4 hours. If there is no seepage, it can be considered that the acceptance of the waterproof construction of the wall is qualified
