How much time can you test the water

After the bathroom is waterproofed, it needs to be thoroughly dried, so that it can do the closed water test, you can contact the residents downstairs in advance, so that the leakage can be informed in time to avoid unnecessary losses of the downstairs residents When doing the closed water test, the depth of water storage can not be less than 20 cm, and the time can not be less than 72 hours, and the water level does not fall is qualified.

Generally speaking, after the waterproofing is done, it can be dried after one night, and then you can test the water.

The bathroom is explained by waterproofing steps

1. Remove the original floor tiles and wall tiles (optional).

If it is a second-hand house renovation, it is necessary to remove the original wall tiles and floor tiles, if it is a new house, then there is no such step, generally use a gray knife, as long as the original floor tiles can be removed.

2. Plug the sewer pipe.

The waterproofing of the bathroom is generally carried out after the completion of the water and electricity reform, so the first step must be done before doing waterproofing is to block the sewer pipe, so as not to block, if it is some small water pipes, then you can use the pipe to block with a nut, for example, like a large sewer pipe, then you can use PVC winding film to block.

3. Ground and wall leveling.

Bathroom waterproof steps, here is usually said that the leveling is simply the ground plastering treatment, the ratio of mortar cement and sand must be modulated, its proportion is probably between: 3, note that the thickness of leveling must not exceed 3cm. The horizontal and vertical errors must be controlled within 5mm.

4. Make a waterproof layer.

First of all, the wall will be cleaned up in the place where the hydropower transformation is slotted, so that the next step can be carried out, and the base layer is cleaned up with cement, such as in the pipe root, floor drain, yin and yang corners, and other places that are easy to leak can be evenly painted.

Bathroom waterproofing should be done several times well

1. Do it twice.

Generally speaking, the waterproofing of the bathroom decoration should be done 2 times, the first time is before the backfill, for example, like the second time is after the backfill, every time you do waterproofing, you must do it according to the standard.

2. The first time.

First of all, it should be evenly and densely brushed on the base surface, generally speaking, like every brush can not be too thick, otherwise there will be a layer, and it is not so easy to dry, and you should also pay special attention when painting, if the paint (especially the primer) has precipitation, it must be stirred evenly before use, each time the dipping material is entered, first stir a few times at the bottom of the barrel, so that there will be no precipitation.

3. The second time.

The second brush after backfilling, at this time it is best to do horizontal and vertical brushing twice, but also to do water injection experiments and other waterproof inspections, check whether it is qualified, if unqualified, you can let workers rework and re-do, if you don't know how to inspect, then you can ask a professional supervision, so it will be more assured.

About 24 hours later. After the waterproof coating is painted to form a waterproof layer (about 24 hours later), the water storage is 20 high, and after 24 to 48 hours, see if the water is significantly reduced or go downstairs to see if there are wet water spots on the roof, and if not, it means that the waterproof construction is successful.

The specific method of waterproofing the bathroom is as follows:

1. Use cement mortar on the ground to find a slope in the direction of floor drain, but the surface should be smooth. 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.

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.

Generally, you can test the water after 8 hours of waterproofing.

Generally speaking, after the waterproofing is done, it can be dried after one night, and then you can test the water. Waterproofing is very important for the bathroom, generally speaking, waterproofing is done twice, doing too much is conducive to waterproofing, but not conducive to tiling; The speed of waterproof drying depends on whether water is added to the waterproof; Those who do not add water dry faster, and those who add water dry more slowly; However, the one without water is too viscous, and it is difficult to brush so evenly on the wall and floor, and it is relatively easy to construct with water; Before the start of the waterproof closed water test, the owner of a household living under his house should be notified and told to pay attention to whether there is any abnormality on the top surface of his bathroom; Put 3-5cm of water and cover the floor of the bathroom; Wait two days, which is 48 hours; Then go to the top surface of the owner's bathroom downstairs to see if there are any water traces or abnormalities.
