Excuse me, will it leak if you don t take a shower in the bathroom and don t do waterproofing?

The bathroom is not waterproof, and if you take a shower upstairs, even if you go to the toilet to flush the water, it may leak out. Let's talk about how to do waterproofing in the bathroom: 1. Use cement mortar on the ground to find a slope in the direction of the floor drain, but the surface should be flat.

The slope near the entrance is small, and the slope near the floor drain is large. 2. The pipeline passes through the root of the floor slab and near the floor drain to strengthen the waterproofing. The pipe root building sealing paste is tightly sealed, and the cement is smoothed after the foot guard, and when the waterproof coating is brushed, the glass wire cloth is reinforced with 1 or 2 layers.

3. The wall is clean and flat, without floating ash and small particles, and the small original corner or slope angle is wiped at the junction of the wall and ground. 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. 5. Paint the façade first and then paint the plane, and the direction of the next painting is perpendicular to the previous one. When the final coating film is semi-cured, the coarse sand particles are thrown to facilitate the combination with the cement mortar in the future.

6. The waterproof layer on the ground should be painted 300mm wide outside the door of the bathroom. The waterproof layer of the waterproof ground should be 200mm higher than the ground. 7. Do a 36-hour closed water test as required.

Yes, because you often use water in the bathroom, and water is fluid

Definitely. , waterproofing must be done. Otherwise, it will be very troublesome in the future.
