How to make the bathroom waterproof

1. Material preparation

How to make the bathroom waterproof? First of all, we must prepare the relevant construction tools, such as: scraper, scraper, brush, mixer, etc. The next step is to choose waterproof materials. Toilet waterproof materials include polyurethane waterproof coatings, polymer polymer waterproof coatings, JS waterproof coatings, K11 waterproof coatings, etc. Can choose these brands of waterproof materials, such as: Henkel, Dongfang Yuhong, Sika, Leibang Shi and other brand waterproof coatings.

Before making the bathroom waterproof, it is necessary to understand its water circuit, and it must be modified according to the actual situation. There are also water, electricity, and heating pipes that need to be laid flat, and some decorative materials must be cleaned. After that, the base surface is flattened with cement mortar and then waterproofed.

Step 2: Brush the first waterproof coating

Before doing waterproofing, make sure the ground is dry and clean. Then start to apply the waterproof coating. First apply it first. There should be no omissions during the application. It must be filled up and firmly combined with the base layer. There should be no bubbles, cracks or shedding. When applying waterproof coating, the height should be the same and the thickness should reach the standard.

Step 3: Brush the waterproof coating a second time

There must be a certain time interval between the second coating of the waterproof coating, and the second coating can not be carried out until the first coating is completely dry. If the interval between them is too short, it will affect the waterproof effect.

The fourth step: laying protective layer

After the waterproof coating is applied, a protective layer should be laid on it, so as to avoid damage to the waterproof layer in the later construction. When laying the protective layer, it must be fully covered, there must be no omissions, it must be firmly combined with the base layer, and there must be no bubbles, cracks, or shedding.

Step 5: Closed water test

After the waterproofing works are completed, the water-closing test should be carried out. The water level of the toilet should not be less than 2 cm. Wait 24 hours before observing to see if there is any leakage. You need to redo it.

What should be paid attention to when the bathroom is waterproof

1. Before the bathroom is waterproof, it is necessary to pay attention to clean the basic level, and there must be no debris such as dust and mold release agent. Also, make sure that the surface is firm and free from peeling, chalking, and bulging.

2. Before waterproofing the toilet, special treatment should be made for the drainage holes, pipe roots, yin-yang corners and some holes. Moreover, the cement mortar on the ground must be leveled before it can be waterproofed, so that no leakage will occur.

3. When the bathroom is waterproof, the wall surface should also be waterproofed. These places about 30 cm high from the ground should be waterproofed to prevent water from seeping into the wall. If the wall of the bathroom is a light body wall, the entire wall of the bathroom must be waterproofed. If there is a bathtub, the waterproof layer of the wall is higher than that of the bathtub. Special attention should be paid to the waterproof treatment of the corners and the waterproof layer should be strengthened.
