bathroom is a very important link in people's daily life, which not only brings unnecessary economic losses to many families, but also may destroy the originally harmonious neighborhood relations. How can we prevent leakage? How to pay attention to waterproofing in bathroom decoration

in the waterproof decoration process of the bathroom, the following points must be paid attention to:

first, try not to damage the original waterproof layer

in the newly delivered buildings, the floors of toilets, bathrooms and kitchens have waterproof layers made in accordance with the relevant specifications. Therefore, without damaging the original waterproof layer, leakage will generally not occur after occupancy. The common problem now is that some bathroom bathing facilities will be added in the decoration and a variety of water supply and drainage pipelines will be rearranged or moved, which has seriously damaged the original waterproof layer of the building. However, there is no repair or re waterproof construction, so that the problem is found after leakage

experience: the waterproof layer is easy to be damaged when redecorating the ground. If it is not repaired in time, leakage will occur in the future, affecting the neighborhood. Therefore, pay attention to protect the waterproof layer during decoration. If it is accidentally damaged, it should be repaired in time to avoid leaving hidden dangers

second, the re laying of floor tiles should be waterproof

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

experience: 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

third, be sure to make the wall waterproof

when bathing in the bathroom, water will splash on the adjacent wall. If there is no protection of the waterproof layer, the next 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

experience: the waterproof of the wall adjacent to the shower location should also be 1.8m high. If a bathtub is used, the height of the waterproof coating of the wall adjacent to the bathtub should also be higher than the upper edge of the bathtub

IV. 24 hours “ Water storage test ” Acceptance waterproof

after the waterproof project is completed, seal the door and drain, 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 the roof of the downstairs house does not leak, the waterproof is qualified. If the acceptance is unqualified, the waterproof works must be redone as a whole and then re accepted

experience: for the acceptance of waterproof construction of light-weight walls, water pouring test should be adopted, that is, use water pipes to spray water on the wall surface with waterproof coating from top to bottom 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 waterproof construction of the wall surface is qualified

v. water pipe grooves in the wall should also be waterproof

during the construction process, when pipes, floor drains, etc. pass through the floor slab, the waterproof layer around the hole must be carefully constructed. The water pipes shall be buried in the wall, and the layout shall be reasonable. The water pipes shall be laid with grooves larger than the pipe diameter, and the plastering in the grooves shall be smooth, and then the grooves shall be painted with polyurethane waterproof paint

experience: the floor of the kitchen and bathroom must be sloped towards the floor drain, and the slope should be increased appropriately. When decorating the pipes in the kitchen and bathroom, try to avoid changing the original drainage and sewage pipes and the location of the floor drain, and avoid leakage caused by re draining the pipes and chiseling the floor to damage the waterproof layer
