The ground is oriented to the slope of the floor drain, cement mortar or bean stone concrete can be used, but the surface should be flat. The slope near the door is small, and the slope near the floor drain is large, so you can grasp it according to the specific situation. The ground is uneven, and it may be uneven when applying waterproof coating, or the ground is easy to crack because of unevenness, which will crack with the ground even if the waterproof paint is applied.

2. Strengthen waterproofing at the root of the pipeline

The pipeline passes through the root of the floor slab to strengthen the waterproofing. After the pipe root building sealing paste is sealed tightly, and the cement is smoothed and the foot pads are smoothed, the glass wire cloth reinforcement layer is 1 or 2 layers when brushing the waterproof coating. The same measures are taken near the floor drain.

3. Waterproof wall treatment in the bathroom

The wall surface is clean and flat, without floating ash and small particles, and the original corner or slope angle is wiped at the junction of the wall and the ground. When brushing waterproof coating, paste 1 2 layers of glass wire cloth reinforcement.

4. The thickness of polyurethane waterproof coating film

The total thickness of the polyurethane waterproof coating film is required to be more than millimeters, which cannot be determined by the number of passes. The pipe root and the corner of the reinforcing layer are brushed first, and after the surface is dried at room temperature for 4h, then a large area is brushed and scraped, and there shall be no leakage and bubbling, and the next layer is painted after 24h curing after large-scale brushing.

Fourth, paint the waterproof layer for the first time. 5. After the first waterproof layer is dry, the second waterproof layer is painted. 6. After 7 days, the closed water test is carried out to see if there is any water leakage.

Hope it helps, thank you.

The 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.

Bathrooms with underfloor heating need to be made two waterproofs.

1. The first waterproofing focuses on preventing the leakage of the ground structure of the steel concrete building, so the waterproof materials selected should have: excellent anti-seepage and leak-proof characteristics; It has good adhesion and extensibility with the ground structure of the steel concrete floor; Long-lasting heat resistance (geothermal water extreme temperature 70 °C) performance.

2. The second waterproof is made on the protective layer of the floor heating pipe, because it also needs to be paved with stone or floor tiles on the surface, so it is necessary to consider the waterproof performance and meet the bonding requirements of the stone or floor tiles and the floor floor, so as to avoid hollowing out the ground stone or floor tiles.

Go to the place where waterproof materials are sold professionally, and the bathroom floor heating waterproofing must be done well.
