Readers Mr. Lin: In the past few years, the family's rental housing was a simple decoration of the guerrillas looking for a road. Recently, the residents reported to me that the sinking of the washbasin on the floor of the bathroom also affected the residents downstairs. The downstairs request must be on the matter. Responsible for repairs. I consulted with some decoration workers. They thought that the waterproof was not done well at that time. At this time, the floor tiles needed to be opened and the waterproof was done again to solve the problem. However, such costs and quantities of work are relatively large. Excuse me, what should I pay attention to when re-doing waterproofing, or is there any better way to remedy it?
Answer: Master Chen, who has many years of experience in cement work, told reporters that waterproofing is a key project in the renovation of bathrooms, and that the remodeling master must do his duty with due diligence.
Mr. Linâ€™s water seepage position is located on the sinking floor. In this case, first check whether the water pipe in the wash basin is in good condition. If the water pipe is leaking, replace the water pipe. If the water seepage situation disappears after replacement, do not re-do it. Waterproof layer. Otherwise, it is necessary to repair the waterproof layer in time to avoid hidden dangers.
If it is necessary to replace the original floor tiles of the bathroom, after the original floor tiles are cut away, the ground must be leveled with a cement mortar first, and then the waterproof treatment should be performed so that leakage of the waterproof coating due to uneven thickness can be avoided. Before doing waterproofing, be sure to clean the floor and brush it with polyurethane waterproof paint two or three times.
The seams between the wall and the ground and the pipe seams between the upper and lower water are the most prone to problems. We must urge the workers to handle these corners. The waterproof coating must be applied in place. The decoration team is required to provide cement mulch to the upper and lower water pipes in the kitchen and bathroom. Brush a 10 to 20 cm polyurethane waterproof coating upward from the ground, and then re-do the polyurethane waterproofing on the ground, and add the original waterproof layer to form a composite waterproof layer. To enhance waterproofness.
When the bathroom takes a bath, the water will splash on the adjacent wall. If there is no protection of the waterproof layer, the partition wall and the diagonal wall of the corner will become mildly damp. So be sure to waterproof the walls before you apply the wall tiles. In the general waterproofing process, the wall surface is to be treated with a waterproof height of 30 cm. However, for a non-load-bearing lightweight wall, the whole wall should be waterproofed, and at least 1.8 meters high should be achieved. If a Bathtub
is used, the height of the waterproof paint on the wall adjacent to the bathtub is also higher than the top edge of the bathtub.
After the waterproof project is completed, close the door and the water outlet, fill the bathroom floor with water to a certain level, and make a mark. If there is no obvious drop in the liquid level within 24 hours, the roof of the house below the downstairs does not occur. Leakage, waterproof to be qualified. If the acceptance is unqualified, the waterproofing project must be redone and re-inspected.
For the acceptance of lightweight wall waterproofing construction, a watering test shall be adopted, even if the water pipe is sprayed continuously from top to bottom on the waterproof paint wall for 3 minutes, and after 4 hours, observe whether the other side of the wall is Infiltration phenomenon will occur, if no penetration phenomenon can be considered wall waterproof construction acceptance.
