Waterproof practices

1. Waterproof coating for toilets

1. Waterproof with paint

The toilet space of ordinary residential buildings is narrow, and there are pipelines passing through the floor slab, etc., so coatings are commonly used for waterproofing.

Membrane waterproofing is rarely used.

2. Two kinds of waterproof coatings for toilets

Nowadays, the materials used for waterproofing are generally paints, and asphalt-based waterproofing coatings are basically not used. Here are two coatings commonly used for waterproofing in the bathroom.

1) Synthetic polymer polyurethane waterproof coating (polyester cloth and glass fiber cloth are added to corners, etc.).

(2) SBS waterproof coating of polymer modified asphalt (carcass reinforcement material polyester cloth, glass fiber cloth, etc. is required).

Second, the toilet waterproof practice

1. The ground before the waterproof treatment of the bathroom.

Leveling

The ground is facing the floor drain.

Direction to find slope, cement.

mortar or bean stone concrete.

Yes, but the surface should be flat. Door.

The slope near the mouth is small, and the slope near the floor drain is large, so it can be grasped 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.

5. Waterproof painting of the bathroom

6. Requirements for waterproof floor painting in the bathroom

The waterproof layer on the ground should be painted 300 wide outside the bathroom door. 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 waterproofing of the bathroom can be done after running the hydropower line, that is to say, after the water and electricity are completed, after the water and electricity tank is smoothed with plaster, you can use a roller brush to dry the waterproof paint evenly on the wall and the ground, especially the corners must be brushed with more pipes, and more brushes should be brushed around, and wait until 24 hours later. It feels like it's dry, brush it a second time. Generally, the waterproof paint should be brushed twice, to three times, that is, the thickness of the wall should be hit to a millimeter, and the ground should reach a thickness of one millimeter, which is still okay.

The coating height is consistent, and the thickness should meet the requirements of the product.

PS: Floor drains, wall corners, pipe heels and other joints should be painted with high elasticity and flexible waterproofing, because the joints between the wall and the floor of the bathroom will be displaced and are most likely to seep water.

2. Brush the waterproof paint for the second time. Note that there needs to be a certain time interval between the second waterproof coatings, and the second pass can only be carried out after the paint is dry, and the specific time depends on the coating. If the interval is too short, the waterproof effect will be greatly reduced.

3. Lay a protective layer. In order to prevent the subsequent construction from damaging the waterproof layer, it is necessary to lay a protective layer on the surface of the waterproof coating. The protective layer should be completely covered with the waterproof layer, no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off.

4. Closed water test. During the closed water test, the waterline at the ground point should not be less than 2 cm, and it should be stored for at least 24 hours, and it should be qualified only after observing that there is no leakage. If there is a leak, it needs to be redone, and you must not be negligent.

1. Bathroom waterproof construction steps.

Step 1: You can use a slightly coarser cement to base the foundation first, and then brush the waterproof paint after the cement is dry. But in painting money, the ground should be flat and there should be no grooves. Water is then sprinkled on the ground to expel the gas from the small holes.

Step 2: Mix the powder and liquid material evenly, and brush the bubbles if there are bubbles when brushing the paint.

Step 3: When brushing the paint, brush it from the same direction, wait 1-2 hours, and then brush the second coat. When brushing the second layer, the direction of the brush should be opposite to that of the first layer, so that the best coverage can be achieved.
