How much do you know about the key points of bathroom waterproof construction? Grass roots**. Before the construction of the waterproof layer, the base layer should be treated, and the yin angle should be polished into an arc or a 45° slope angle. When the flatness of the board surface is poor, a leveling layer should be made. How many layers of waterproofing should the bathroom do? From the perspective of the overall structure, I personally think that the waterproofing of the bathroom should be divided into two layers. The entire construction phase of the toilet was completed in two parts.
Specifically, the waterproofing of the toilets on the following two floors is required to ensure the effective waterproofing effect of the toilets. For the waterproofing of weak parts of the bathroom, it is generally necessary to brush more than twice first. What should be the height of a waterproof brush on the wall? Regarding the waterproof height of the bathroom wall, the waterproof wall of the bathroom is brushed to the top, because the wall tiles of the bathroom are attached to it. If there is only 1 layer of waterproofing. 8 meters, then the water absorption of the upper and lower walls is different. It may fall off unevenly, and the rework rate is high in the later stage.
Floor waterproofing precautions: Make sure the surface is clean. The renovation site is inevitably messy. Therefore, before waterproofing, the area that needs to be waterproofed must be cleaned to prevent decoration garbage, sand and other debris from falling on the surface, resulting in waterproof failure. Attention should be paid to the pipeline structure. Waterproofing details in the bathroom are crucial. For example, at the junction of the sewer pipe and the floor, almost 90% of all waterproofing failures are caused by this location. The material of the sewer pipe is different from the material of the floor. If the waterproofing is not properly treated, the waterproofing layer may fail in the future and become a leak point. A closed water test must be performed. This step is crucial.
After the completion of the waterproofing of the ground, a 2-day closed water test must be carried out. If there is no water leakage downstairs during this time, it is best to continue construction. Don: Don't ignore closed water trials in order to meet deadlines. Therefore, after the later renovation is completed, waterproofing failures and water seepage will be found. In this case, it will be cumbersome to maintain. Basically, the floor tiles must be dug up and waterproofed. Cosmetic and organoleptic quality checks. The waterproof layer of the coating should be firmly bonded to the base layer, and the surface should be flat and evenly brushed, and there should be no defects such as flowing, wrinkling, bubbling, such as exposed and warped carcass.
