Before the bathroom renovation, some friends who knew about the waterproof height of the bathroom knew that if the wall of the bathroom was not waterproof, that is, the height of the bathroom was not high enough, it would cause water seepage problems on the wall, which would result in loss of money and affect the normal life. So there is a standard for bathroom waterproof height? The following Xiao Bian will introduce you to the bathroom wall waterproofing practices and bathroom waterproof height standards for your reference.
National standard for bathroom waterproof height
Waterproof height of the toilet The national standard specified by the National Construction Committee is 1.8 meters. The building has been waterproofed in the building, and the waterproof layer extends from the ground to the wall, 250MM above the ground. However, the waterproofing of the wall surface is basically not provided. The height of the waterproof layer of the shower surface wall according to the conventional bathroom shall not be less than 1800 MM, and the thickness shall not be less than 1.5 MM, and the 24-hour water storage experiment must be performed after the waterproof project is completed.
Bathroom waterproof height wall waterproofing practices
1, polyurethane waterproof coating practices:
1. Look for slopes in the direction of floor drain. Cement mortar or adobe concrete can be used, but the surface should be flat. The slope near the entrance is small, and the slope around the floor drain is large. Grasp according to the specific situation.
2, the pipeline through the root of the floor, strengthen the waterproof. Pipe root construction sealant seal, cement wipes smooth feet, brush waterproof coating glass fiber reinforced layer 1 to 2 layers. The same measures are taken near the floor drain.
3, the wall surface clean and smooth without light dust, small particles, wall ground at the intersection of small original angle or slope angle. When the waterproof paint is applied, the glass cloth is reinforced with 1 to 2 layers.
4, the total thickness of polyurethane waterproof coating requires more than 1.5 mm. Can not rely on the number of times to decide. Root tube, corner reinforcement layer at the first brush, room temperature 4h after the dry, and then a large area brushing, smearing. There must be no leakage or bubbling. After a large area of ​​brushing and curing for 24 hours, brush the next layer.
5, first brushing the facade after the brushing plane, the next time brushing direction and the vertical again. When the film is semi-cured for the last time, the coarse sand is thrown to facilitate the later combination with the cement mortar.
6, the ground waterproof layer should be brushed out of the bathroom door 300 wide. Waterproof floor waterproof layer should be higher than the ground 200, bathroom with a shower wall waterproof layer should be higher than the ground 1800 (L8 recommended to do waterproofing full wall).
7, there is a stand-up tube at the office (including the L8 old pipe post), it is recommended to do after the waterproof cover pipe, and then make up a partial waterproof, if not damage the ground waterproof layer, can be closed water experiment.
Second, coating waterproof layer construction
HB kitchen special waterproof coating thickness is generally 1.1mm, 1.5mm, 2.0mm, depending on the design thickness, can be divided into two or three times for coating construction.
1, open the packaging barrel and stir evenly.
2, the first layer of paint film: the already mixed HB kitchen bathroom special waterproof coating with a plastic or rubber scraper evenly smeared on the base surface has been coated with a good primer, the thickness of 0.6mm, to be uniform, draw The amount of 0.6 ~ 0.8kg/m2 is appropriate, the first wall surface after operation, retreat from the inside out.
3, the second coating: the first coating curing to sticky, according to the first pass of material construction methods, the second coating waterproof construction. In order to make the film thickness uniform, the direction of the squeegee must be perpendicular to the first pass of the squeegee. The amount of squeegee should be slightly less than the first pass, and the thickness should be 0.5mm.
4, the third coating: After the second coating is cured, according to the above two construction methods, the third pass squeegee, the amount of scraping to 0.4 ~ 0.5k/m2 is appropriate (such as the design thickness of 1.5mm For the above, the fourth brushing can be performed.
5. Withdraw coarse sand binding layer: In order to protect the waterproof layer, the waterproof layer of the ground may not remove the stone slag binding layer. The combination layer may use 1:1 of 108 glue or public tyrant cement slurry to perform the sweeping treatment, after the construction of the waterproof protective layer on the ground , Roll over the waterproof coating on the waterproof layer of the wall, when it is not solidified, remove 2~3mm sand on the surface to increase its adhesion to the surface layer.
6, protective layer or decorative layer construction.
Xiao Bian summary: In the home improvement toilet waterproof height and wall waterproof construction, we must grasp each construction node, from the beginning to do a good job of prevention, to minimize the late because of the toilet waterproof height is not enough to bring about the various annoyance, I hope this This article is helpful to everyone.
