What should be done in the waterproof of interior decoration

Indoor decoration, waterproof engineering is not in place, the consequences are very serious, especially the bathroom, but also most likely to become the hardest hit by water leakage. Some people are not particularly aware of waterproofing, and even some decoration companies are not aware of the owner and cut corners. In order to decorate the small white to decorate their own small nest of the United States and the United States, and now to everyone to introduce the process of doing waterproof.

1. Cleaning We need to do a preparatory work before the waterproofing project begins: Clean the place where waterproofing is needed. No matter if it is a kitchen, bathroom, or a sinking area, as long as it is a place that needs waterproofing, building slag and rubbish must be cleaned.

2, the first time after the waterproof clean, we can carry out the first step of the entire waterproofing project: the first time waterproof, brushing waterproof coating on the sinking area, the general brushing height exceeds the backfill elevation 20cm oh.

3, backfill After the first waterproof, you need to carry out the second step: waterproof construction backfill work! Before backfilling, we also need to do some preparatory work. The first is to use the “masonry method” to protect the water pipes so as to avoid damage to the water pipes during the backfilling process. The carbon slag is used for backfilling. If it is used, it is hard. The slagging is easy to cause damage to the water pipe. The carbon slag is not as hard as the slag, and will not damage the pipe. In addition, the compaction of carbon slag is better than that of slagging, reducing the probability of collapse after backfilling, and the water absorption rate is also greater than that of slagging.

4. After the plaster is backfilled, perform the third step, that is, before the second time of waterproofing: Plastering. It should be noted that when backfilling and plastering, it is necessary to go to the floor drain direction to find the slope. The purpose of this is to let the mortar. Layers of water can be drained to a location, and with "secondary drainage" measures, moisture can be prevented from returning to the bathroom.

5, the second time waterproof The next step is the fourth: that is, our second waterproof, the second time waterproof, flexible waterproof coating and polypropylene double protection. The second time after the waterproof, it is the mortar layer and tile paving!

6, reserved for the second drainage hole In fact, in addition to our daily waterproof water, the mortar layer is also water; in general, can be passed through the floor drain slope mentioned earlier, but we in order to better effect, will be next to the water pipe Reserve secondary drainage holes, the water can also go through the secondary drainage holes we set aside so that it will not cause water accumulation in the mortar layer eventually return to the interior. In the specific operation, we will place small stones next to the secondary drainage holes to prevent the drainage holes from being blocked by the mortar layer to avoid failure. These small links are often the key points that determine the success or failure of waterproofing projects.

1. Here, we must emphasize the next secondary waterproofing. The secondary waterproofing is best done with double waterproof protection of flexible waterproof coating and polypropylene. The national standard requires that the waterproof area of ​​the bathroom needs to be 1.8 meters high in the shower area. The bathroom is not just a shower area, moisture is also a very important part of the waterproof.

2, because there is no shower in the kitchen, so the waterproof height is not so high requirements, the general waterproof height is 30cm, only need to strengthen the treatment of the location of the basin on it.
Waterproofing is not only the bathroom and the kitchen, but also the living balcony will have floor waterproof and 10cm high wall waterproofing.

3, after the waterproof project must close the water test Oh! The closed water test on the ground needs to inject water at a certain level of water. After 48 hours, two points need to be observed. One is to see if there is a decrease in the water level, and the other is to see whether the ceiling below the corresponding floor is seepage.
