How does the floor waterproofing in the bathroom cost?

The whole family's polypropylene waterproofing membrane, 14-16 yuan square meters.

Good SBS, 25 yuan square meters.

Coating film, according to the thickness of the difference, 22-40 yuan square meters.

Now the most commonly used is:

Polyurethane waterproof coating practices:

1: The ground is facing the slope of the floor drain direction, cement mortar or bean stone concrete can be, but the surface should be smooth. 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.

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

4: The total thickness of the polyurethane waterproof coating film is required to be more than millimeters. It can't be decided 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. There shall be no leakage and bubbling. Brush a large area for 24 hours and then apply the next layer after curing.

6: The waterproof layer on the ground should be painted 300 wide outside the door of the bathroom. The waterproof floor waterproof layer should be 200 meters higher than the ground, and the wall waterproof layer of the bathroom with shower should be 1800 meters higher than the ground (L8 recommends waterproofing the full wall).

The price is different in different places, generally about 37 yuan m2, about one square meter.

There are many waterproof methods, and it depends on what price you do to set for you.

The base should be smooth and clean, and there should be no debris, and the yin corner at the junction of the wall and the ground should be made of small figure 2 and brush waterproof materials.

You can use polyurethane or JS waterproof coating film, at least two times, the first time is dry and then brush the second time; If the wall of the shower against the wall is shared with the neighbors, the painting height is not less than one meter, and the rest of the position is one meter higher than the ground.

3. After the waterproof material is dry, do a closed water test, the closed water time is not less than 24 hours, go downstairs to check the waterproof effect, and no leakage is qualified.

JS price is 30-35 yuan per square meter for work and materials, 45-50 yuan per square meter for polyurethane, and the price varies from place to place, which is also related to the size of your project.

Brush waterproof paint, the ground is fully brushed, and the strong surface is brushed to 30 40 cm The wall with a shower should be brushed to the meter If there is a wall that is more shared by the bedroom and there is a wardrobe on the bedroom side, then the wall needs to be fully brushed We quote 50 square meters here.
