Whether the kitchen should be waterproof or not, let's first see what will happen if the kitchen is not waterproof. For the kitchen, waterproof efficiency is not high, but it can't be said to be unimportant. Another water source in the kitchen is at the upper and lower intake, and the main reasons for the overflow accident are as follows:
Reason one: the sewer is blocked, forming backwater;
The second reason: the water inlet pipe broke and a large amount of water leaked out;
Reason four: the basin is not tightly closed, and the water splashed on the countertop during washing flows in through the seam.
From the above three aspects, it is very necessary to do waterproof engineering in the kitchen. So, how should this kitchen be waterproof?
1. Try to protect the original waterproof layer.
After delivery, there are waterproof layers on the floors of toilets, bathrooms and kitchens in the building, which shall be carried out in accordance with relevant specifications. Therefore, if the original waterproof layer is not destroyed, the probability of such leakage is extremely small. At present, the existing problem is that in order to increase some bathing facilities in the decoration, various water supply and drainage pipelines are modified, which destroys the original waterproof layer of the house. But this broken clue is not easy to find, and it will not be found until it is leaked.
Therefore, if the waterproof layer is damaged, but it is not repaired in time, it will leak water in the future and endanger neighbors. I still want to remind you to protect the waterproof layer when decorating. If it is damaged carelessly, it should be repaired in time to avoid leaving hidden dangers.
2. The surface of floor tile must be waterproof.
If you want to replace the original floor tiles in the bathroom, you need to level them with cement mortar after roughening, and then do waterproof treatment. This is to avoid the leakage problem caused by the thickness of waterproof coating. Don't forget to clean the floor before waterproofing, and then use polyurethane waterproof coating when the floor is sanitary. It needs to be brushed 2-3 times repeatedly.
At this time, the joints between the wall and the ground, and the joints between the upper and lower pipes and the ground can not be ignored. These two locations are prone to hidden dangers. It is necessary to supervise the construction personnel at any time, handle the details such as edges and corners, and apply waterproof paint in place. We want to ask the construction team to do a good job of cement root protection for the upper and lower pipes in the kitchen and bathroom. We need to paint 10 to 20cm polyurethane waterproof coating from the ground, and then carry out polyurethane waterproof work on the ground. Coupled with the original waterproof layer, a composite waterproof layer is formed, so that the kitchen will be more waterproof.
3. Waterproofing of wall surface can not be ignored.
The bathroom is the place that uses the most water, and it is inevitable that water will splash on the surrounding walls when taking a bath. Without the protection of waterproof layer, this wall and the opposite corner wall are prone to damp and mildew. Therefore, before paving the wall tiles, we must do enough waterproof work on the wall. Usually, the wall will be 30cm waterproof. If it is a non-load-bearing lightweight wall, the front wall must be waterproof and at least 1.8m high. The wall closest to the shower room should also be waterproof to the height of1.8m. If a bathtub is used, the height of waterproof paint on the wall near the bathtub should be higher than the upper edge of the bathtub.
Don't forget the water pipe trough on the wall.
During construction, when pipes and floor drains pass through the floor, attention should be paid to the waterproof layer around the hole, and the construction should be cautious. The buried water pipes in the wall should be carried out reasonably. The water pipes should be laid in a groove with a diameter larger than the pipe diameter, plastered until smooth, and polyurethane waterproof coating should be painted in the groove. The floor of the kitchen and bathroom must be inclined to the floor drain, and the slope should be increased appropriately. When decorating the internal pipes in this area, try not to change the original drainage pipes, sewage pipes and floor drains, so as to avoid re-arranging pipes and cutting buildings to destroy the waterproof layer and cause leakage.
5.24-hour water storage test acceptance.
After the waterproof project is completed, it is the acceptance link. At this time, it is necessary to seal the door and drain. When the toilet floor is full of water and reaches the corresponding liquid level, it should be marked. If the liquid level does not drop significantly within 24 hours, especially if there is no leakage on the roof of the downstairs residents, the waterproofing is qualified. If the acceptance is unqualified, all waterproof works need to be redone and then re-accepted.
For the acceptance of different waterproof construction, its standard specifications are different. The acceptance of waterproof construction of light wall is water spraying test. Waterproof construction of wall from top to bottom, spray water pipes on the wall coated with waterproof paint for 3 minutes, and observe the performance of the other side of the wall after 4 hours, which is considered qualified. If there is no water seepage, the wall waterproof construction can be regarded as qualified.
If the owner has enough funds, the kitchen waterproof project should be done. Although the waterproof efficiency of the kitchen is not obvious, it is still necessary. Should the kitchen be waterproof? I believe you have a good idea.
