How to make bathroom waterproofing yourself?

The steps to make the bathroom waterproof are as follows:

1. The floor of the bathroom is sloped with cement mortar, the direction is the direction of the floor drain, the slope of the bathroom door is relatively small, and the slope of the floor drain side will be relatively large.

>2. Pipe through the root of the floor slab and the position near the floor drain to strengthen the waterproofing, the pipe root is sealed tightly with sealing paste, and after the cement is smoothed and the corners are protected, when the waterproof coating is applied, paste 1 to 2 layers of glass cloth reinforcement layer.

>3. Treat the wall of the bathroom to be flat, no small particles, and no floating ash hanging, wipe the small original corner or slope foot at the junction of the wall and the ground, and paste 1 to 2 layers of glass cloth reinforcement layer when brushing waterproof paint.

>4. The total thickness of the polyurethane waterproof coating film needs to be 15mm, first paint at the root of the bathroom pipe and the reinforcing layer of the corner, and then paint and scrape in a large area after 4 hours at room temperature.

>5. The waterproof layer should be painted on the façade of the bathroom first, and then painted on the plane, the direction of the next painting needs to be perpendicular to the direction of the previous time, and wait until the last coating film is half cured, and then throw the coarse sand particles, which will be easier to combine with cement mortar. The waterproof layer of the bathroom floor should be painted to a position of 300 mm outside the door, and the waterproof layer of the waterproof floor should be kept 200 mm away from the ground.

>6. After 24 hours of waterproofing, you can start to do the closed water test, the closed water test should be filled with water, the time needs 24-48 hours, the water depth should not be less than 20mm, and the water storage height is generally 30 to 40mm.

Before construction, it is necessary to ensure that the dry waterproof coating of the ground should be coated, without any omission and the base layer should be firmly combined, no cracks, no bubbles, no falling off The height of the painting is consistent, and the thickness should meet the requirements of the product regulations.

Use diluted concrete to repair and level the damaged, ground water pipes, wall water pipes and other places that need to be repaired, and wait for the cement to basically solidify and dry; Clean the ground and wall, clean the bottom with water and paint it evenly, and use the bristle brush to paint the waterproof paint longitudinally and horizontally after the water does not leak and basically dry, and brush it 3 times.

1. Ground treatment.

Before waterproofing, be sure to level the ground, if the ground is uneven, it may affect the effect of waterproofing, and may also cause cracking and leakage caused by uneven thickness of waterproof coating. 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 water seepage is most likely to occur.

2. Wall treatment.

If the bathroom has a shower room, the waterproof should be 180cm, and if there is a bathtub, the waterproof height of the wall adjacent to the bathtub should be 30cm higher than the bathtub

3. After the waterproof layer is done, a certain amount of time should be left to make the waterproof layer better integrated with the building, and then the protective layer on the waterproof layer and then paved the floor tiles.

4. Waterproof construction is a concealed project, and the follow-up construction may also damage the waterproof layer, if the floor tiles have been laid, do not smash the floor tiles, use professional waterproof materials to plug all the gaps and do a good job of waterproofing. It is also suitable for waterproofing projects after the failure of the waterproof layer in the bathroom.

5. Waterproofing is a systematic project, and the causes and treatment methods are different in each place. Materials are the foundation, construction is the key, and follow-up service is the guarantee.

Preparation: Reinforced concrete floor slabs.

1:3 cement mortar to find the slope layer, slope to the floor drain, a smoothing.

Acrylic waterproofing, polymer cement waterproofing or polyurethane waterproofing.

30mm thick dry hard cement mortar bonding layer.

How, there is no leakage in the water pipe, and it can be repaired locally! First of all, the tile joint ditch is good, and then the address mouth, waterproof, toilet and stool are waterproof, so that the leakage point, and then high-pressure grouting, is the bathroom without smashing bricks waterproof!

Make your own waterproofing with acrylic, that is, the price is high and the construction is simple. After the base layer is leveled, clean it. When painting, the first pass is vertically crossed with the second pass, and the first pass can be brushed a second time without touching your hands. Generally, the drying time is about 24 hours

For the toilet waterproofing to meet the following five standards: no leakage, no water accumulation, no overflow, no water seepage, no conduction!

Step 1: Waterproof and watertight!

1. The waterproof material is best coated with waterproof material, which is often referred to as waterproof coating. This part is mainly the risk of fakes, go to a regular store to buy, or the decoration company will give you an inspection after purchasing, the quality of the big brand products is good, and it will not be very expensive, the key is that the bathroom area is also small, and the overall budget can not be consumed.

2. Before waterproofing, the surface of the cement surface base should be treated flat, and there should be no defects such as hollowing, sanding, cracking, etc., and all yin and yang corners should be made into an arc shape with high-standard cement mortar. Finally, the moisture content of the base layer should meet the construction requirements of waterproof materials (please see each product description for details).

3. The general more provincial approach is the non-shower area, the waterproof layer should extend from the ground to the wall, more than 30 cm higher than the ground, and the height of the waterproof layer on the wall in the shower area shall not be less than meters.

4. In the early stage, the waterproof membrane is paved, the yin and yang corners are handled, the membrane should be more than 30 cm higher than the ground, and then the waterproof coating should be painted evenly repeatedly, and the general ground is brushed horizontally and vertically twice, and the wall is brushed horizontally and vertically twice, without missing brushes, bottoms, and bubbles, and the average thickness shall not be less than millimeters.

5. After the completion of the overall waterproof project, a 24-hour water storage test must be done. Special instructions: Since the sewer is a place with a high incidence of accidents, it is necessary to repeatedly brush several times separately at the junction, and brush thickly and evenly to prevent accidents.

At the same time, many closed water tests are too shallow and the water pressure is not enough, which is not conducive to testing the airtightness, so it is best to store more water.

Generally speaking: a renovation company or doing it yourself will only do the first step! And the only step!

But for the sake of future home life experience, it is recommended that the last four parts should also be considered for details, please see my article "How to do waterproof?" The bathroom will not leak! Five standards for toilet waterproofing [Yichang Decoration]".

Use waterproof paint to do waterproofing, do the kitchen and bathroom three times, paint the floor fully, and the wall should be 30 cm above the ground. Generally, when the construction project is completed and the property is accepted, it has been waterproofed once, but if you are responsible for yourself, you still brush it three times, and do a closed water experiment after it is all dry, that is, fill the ground with water, and go downstairs to check whether there is water seepage after 48 hours, and you can hand over the work without water seepage. Asphalt waterproofing will have a great smell and pollution.
