What are the waterproof requirements for professional toilets and waterproof acceptance specificatio

Bathroom waterproofing requirements are very important, waterproofing is not done well, not only will bring trouble to yourself but also to the residents downstairs, so when doing bathroom waterproofing, it is necessary to be strict. So what are the waterproof requirements for professional toilets? What are the requirements of the waterproof acceptance specification?

Professional restroom waterproofing requirements.

1. First of all, the ground waterproofing should do a good job of the base layer, the base layer is the layer of the cement mortar surface, and the surface should be smeared flat. The waterproofing of the walls should be completed before the tiles are laid.

2. Bathroom decoration should first level the ground, if the ground is not flat, it is easy to accumulate water, and if the water is accumulated for a long time, then there will be water leakage, of course, waterproof materials are also very important, it is best to buy a brand, and the quality is guaranteed.

3. Leakage is prone to occur in places such as drainage outlets and yin and yang corners, so special waterproof and plugging treatments should be done.

4. To do fine coating, first of all, we must first coat the primer, and then use a plastic or rubber scraper to evenly apply the waterproof coating on the surface of the base layer. The wall should be kept clean and flat, without floating ash, small particles, etc., after doing waterproof work, the waterproof layer is completely dry, and then a large area of brushing, scraping, there can be no leakage or bubbling and other phenomena.

5. The waterproof layer should also be applied at the door of the bathroom, the height of the waterproof layer on the bathroom floor should be 200mm higher, and the waterproof layer on the shower wall should be higher than the ground. The front of the bathroom with a bathtub should also be higher than the upper edge of the bathtub.

What are the requirements of the waterproof acceptance specification.

1. Inspection after the construction process.

The base treatment, hole cleaning, and equalization work before waterproof construction should be checked and confirmed by the supervising engineer before the next step of construction.

2. Acceptance after waterproof painting of the bathroom.

The first waterproof layer painting must also be supervised and accepted before the second waterproof painting can be carried out.

3. The waterproof layer needs to be accepted after it is painted and dried.

After the waterproof layer is dried, the waterproof layer should be inspected and accepted to see whether the waterproof layer is coated, whether the coating is uniform, whether the thickness of the file meets the requirements, and whether there are defects such as bulging, cracking, and warping on the surface.

4. Acceptance one by one.

After the waterproofing project is completed, the bathroom will do a closed water test, but the acceptance can not be negligent, and all the toilets must be accepted one by one. Summary:

1.Material acceptance.

Waterproof construction should be used for coating film waterproof materials, and the performance of waterproof materials should meet the provisions of the current national standards, and there should be a product qualification certificate.

2.Acceptance at the grassroots level.

The surface of the base should be smooth, and there should be no defects such as hollowing, sanding, and cracking. The moisture content of the base layer should meet the construction requirements of waterproof materials. The waterproof layer should extend from the ground to the wall, 250mm above the ground. The height of the waterproof layer on the bathroom wall should not be lower than 1800mm.

3.Waterproofing layer.

The thickness and strength of the protective layer cement mortar must meet the design requirements, and it is strictly forbidden to destroy the waterproof layer during operation, and the ground flooding slope should be done according to the design requirements, and the drainage should be smooth, and there should be no water accumulation.

4.Process acceptance.

The waterproof cement mortar screed layer is densely combined with the foundation, without hollowing, the surface is smooth and clean, no cracks, sanding, and the yin and yang angles are made into an arc. The use of construction stubble should be lapped in the direction of flowing water, and the lap width should not be less than 100mm, and more than two layers of fiberglass cloth should be staggered by half of the width when lapping up and down.

5.Water storage experiment.

After the completion of the waterproofing project, a 48-hour water storage test must be done. Use sand to tightly block the floor drain with plastic bags to prevent the stored water from running away, and then waterproof; During this time, observe whether the water level has dropped significantly, especially whether there is any leakage on the roof of the house downstairs, to check whether the waterproof construction is qualified.

To do fine coating, first of all, the primer should be coated first, and after the primer is applied, then use a plastic or rubber scraper to evenly apply the waterproof coating on the surface of the base layer, the thickness should be, the coating should be uniform, there can be no deposition and bubbles locally, and the bonding should be tight. The wall should be kept clean and flat, without floating ash, small particles, etc., after doing waterproof work, the waterproof layer is completely dry, and then a large area of brushing, scraping, there can be no leakage or bubbling and other phenomena.

5. The waterproof layer should also be applied at the door of the bathroom, the height of the waterproof layer on the bathroom floor should be 200mm higher, and the waterproof layer on the shower wall should be higher than the ground.

4. Acceptance one by one.

After the waterproofing project is completed, the bathroom will do a closed water test, but the acceptance can not be negligent, and all the toilets must be accepted one by one.

Process requirements.

1) The floor of the bathroom must be compacted, wiped with the beating, compacted and wiped to form a waterproof layer of its own.

2) The gaps around the pipe holes and casing holes of all floor slabs are poured with bean stone concrete mixed with expansion agent, and the expansion concrete is poured by hanging mold if the holes are larger. After all the treatment, the irrigation experiment was carried out for 24 hours

If there is no leakage, the next process - cement mortar screeding can be carried out.

3) After the completion of the base leveling layer, it should be solid and flat, clean without hollow drum loosening, obvious cracks, hemp surface, sanding and other phenomena, otherwise cement glue putty should be used to repair it to make it smooth. All corners are made with a radius of 10mm

All pipe fittings, floor drains or drains and other parts must be in place correctly, installed firmly, without any loosening, the end is smooth, and the caulking material is used for embedding and leveling. There is no protruding sharp object in the base layer, and the moisture content meets the requirements.

4) When the surface of the base layer is kept wet, the first layer of waterproof layer can be painted, and the special brush for cement workers should be used for brushing, and the thickness is.

When the first layer of waterproofing is dry, apply the second layer of waterproofing, and when the weather is higher and hotter, spray a layer of fog water on the surface of the first layer of waterproof layer to moisten.

Unless the weather is extremely hot and dry, the elastic water barrier generally does not require special curing treatment. At room temperature, you only need to spray water on the surface of the coating three times on the first day.

5) After the construction of the waterproof layer is completed, the irrigation test should be carried out, and the water storage depth should be 10cm higher than the waterproof layer for 24h

After checking that there is no leakage, the construction of the protective layer can be carried out.

For the phenomenon that the bathroom is prone to water leakage, when making a waterproof layer, it is necessary to check it layer by layer. After the construction of the waterproof protective layer is completed, it is necessary to do another irrigation experiment to ensure that there is no leakage in the bathroom.
