Anonymous users2024-01-23The bathroom is equipped with underfloor heating, which also needs to be waterproof. Nowadays, the general bathroom has caissons, so in general, it needs to be waterproofed three times.
The first time is that a waterproof is required before backfilling, and this layer also needs to be tested for closed water.
Secondly, the second layer is the ground backfill, and a layer of waterproofing needs to be done after leveling.
The last layer is to do waterproofing again after installing floor heating, and this layer also needs to do a closed water test.
But this is mainly for you to install plumbing, if it is electric heating, then the layer after leveling can also be optional. The focus is on waterproofing the bathroom after installing floor heating, and it is recommended to use mortar waterproofing agent, so as to better withstand the high temperature of floor heating.
The sunken toilet waterproofing needs to be done twice, the bottom layer, the pipe is then backfilled, and then the surface is covered, and then the whole is waterproofed, so you understand.
Waterproofing should be done under the floor heating to prevent the loss of the floor heating pipe from breaking down. It is best to do waterproofing again after laying underfloor heating.
The waterproofing of the bathroom must be before the decoration, the first process is to do waterproofing, and the waterproof must be tested after the waterproofing, the test time is not less than 12 hours, and the quality of waterproofing is observed. Only when the waterproof is qualified can the next process such as tiling can be carried out. After tiling or laying the floor, it cannot and cannot be waterproofed. FYI.
It depends on the situation, the correct way is to brush the bottom surface 2-3 times with a waterproof layer, in order to prevent water from penetrating along the groove to the other side of the wall. Of course, if you are sure that there will be no water pipe leaks in some places (without pipe fittings), you can brush it directly on the surface. Suppress and do a closed water test.
Common floor heating is divided into electric heating and plumbing, under normal circumstances, if it is electric heating, the bathroom can first do a waterproof in the backfill pit, and then backfill leveling and install electric heating, and then do a waterproof on the electric heating, a total of 2 times, the kitchen can be done on the leveled ground first, and then do it once on the floor heating, a total of twice. If it is plumbing, then the kitchen is the same, and the bathroom is recommended to do it three times, namely in the backfill pit, after the backfill leveling, and after the installation of floor heating. For materials, it is recommended to use mortar waterproofing agent, because of high strength, puncture resistance and high temperature resistance, so that the protection period can be longer.
