Leaking and seeping water in the bathroom is a very annoying phenomenon. Therefore, it is very important to do the waterproofing in the early stage. Today, the home will bring you a super-complete waterproof encyclopedia. Let’s take a look!
1, ground treatment
bathroom floor elevation design should be 20 ~ 50mm lower than indoors. The drainage slope of the ground facing the floor drain is generally 2% to 3%. When the bathroom is backfilled and leveled, it should be radiated in the direction of the four sides with the floor drain as the center. Find the slope, use the scraper to smooth the surface, and the surface should be smooth. There is no pit on the surface, no gap, no sand, no water.
2, wall treatment
Wall surface treatment should be about 300mm high waterproof coating to prevent water from seeping the wall back. If the bathroom has a shower room, it should be waterproof to 1800mm. If there is a bathtub, the waterproof height of the wall adjacent to the bathtub should be 300mm higher than the bathtub.
3, the root of the pipeline is reinforced waterproof
floor drain, corner, pipe and other joints, use a flexible and flexible waterproof brush, because the bathroom wall and the ground The joints between the joints are displaced most easily. The tube root part is sealed with a sealing paste. After the cement is smoothed, the reinforced layer of the glass cloth is reinforced with 1~2 layers. Take the same measures near the floor drain.
4, polyurethane waterproof coating film thickness
polyurethane waterproof coating film thickness of 1.5 mm or more, can not be determined by the number of passes. The root of the tube and the corner reinforcement layer are brushed first. After the surface is dried for 4 hours at normal temperature, the large area is painted and scratched. There must be no scratching or bubbling. After a large area of painting for 24 hours, the next layer is applied.
5, waterproof test must be done
After the bathroom construction is completed, all the water in the toilet is blocked, and a 25 cm high is built at the door. “Kan”, then fill the bathroom with 20 cm of water. After 24 hours, check the surrounding walls and the ground for leaks. This 24-hour waterproof test is the key to ensuring the quality of the bathroom waterproofing project.
Waterproof key misunderstanding
1, try to avoid eye-catching on the wall
For some towel rods and other hardware, on the wall The thickness of the eye should not exceed 2 cm, otherwise it will easily damage the waterproof layer of the wall. When the pipe must be grooved to change the pipe, the waterproof material should be carefully painted on the inner wall of the groove to prevent the condensate from seeping out of the wall in the future.
2, do not arbitrarily change the pipe design
Otherwise it will easily lead to water leakage in the future. Try not to move the water supply pipeline over long distances. The longer the pipeline, the greater the chance of failure. It is best not to change the position of the toilet at will, otherwise it will easily leave hidden dangers for future leakage.
3, the corner of the bathroom to do the seam treatment
bathroom corner, to do one or two layers of reinforced polyester cloth seam treatment, to prevent waterproof layer Cracking and leaking. In addition, the pipe joints can be used to build the riser with light bricks, and the non-woven fabric is also placed at the female corner of the riser to prevent water seepage.
4. Strict and orderly construction
In order to avoid water leakage in the corner of the wall, the order of paving the bathroom wall tiles and floor tiles should be strictly emphasized. Wall tiles should be laid first, and the last row should be left unpaved near the ground. When the waterproof and floor tiles are all paved, after the wall is covered, the remaining wall tiles are laid.
5. Pipes of different materials can not be connected.
Two sections of pipes made of different chemical materials, even after hot melt, squeeze them with external force. Pressed together, after the solidification, there will still be gaps, eventually causing water seepage.
