How to do waterproofing in the bathroom? Expensive or not

Toilet waterproofing practices:

Basic material selection: new waterproof materials such as cement mortar, old ones such as acrylic are commonly used toilet waterproof materials. We should choose based on the principles of easy construction, environmental protection and good quality.

The first step in how to do bathroom waterproofing is to brush the joints in place. The joints between the walls and floors of the bathroom and the joints between the water and water pipes and the floor are the most problematic places. During the construction, you must urge the workers to deal with these corners and corners, so the waterproof coating must be applied in place.

First of all, the ground has to be leveled, 30 cm from the ground wall bricks are also removed and leveled, to be dried, two kinds of waterproofing: membrane, coating, if you use membrane, it is best to use EPDM waterproof membrane, if you use paint, it is best to use rubber modified asphalt waterproof coating, the ground and wall are done together, after doing it, it is like a basin, it is best to paint three times with paint, the main part is the floor drain pipe mouth, toilet pipe mouth, the ground and the wall joint, the weak part of the ground, do before carefully cleaning the pipe mouth with a toothbrush, Rinse while brushing, clean with waterproof cement carefully wipe the ground and the joint of the pipe mouth, the water does not leak inside the best to add some asbestos powder, after thoroughly drying and the ground together with the overall waterproof, the toilet fixed wire should be laid first, more than one cm from the ground The mouth of the screw is wrapped with masking paper and do not stain the waterproof coating, the following part is also brushed with waterproof paint with the ground to prevent the water from seeping down the fixed wire in the future, and you can put the water after drying, soak for 48 hours, the water should be put 10 cm deep, otherwise it will be tried in vain, You said that the plumbing pipeline in the seal before taking a few photos, in case there is a problem in the future can check the location, with the high grade cement all sealed and leveled, the key is that the cement must not be bought fake, otherwise it is also done in vain, good cement looks blue after drying, high density, high hardness, high strength, not easy to leak, do not use white cement to make up the seams after sticking the floor tiles, you go to buy a few bottles of Taimao brand plastic steel clay, but also to prevent not to buy fakes, floor tile joints, wall corner joints, etc. are all made up with plastic steel soil, if you do this, There is absolutely no possibility of a water leak in 10 years, unless the house settles and causes a slight crack in the ground, and then raise the problem. I wish you success!

Special attention should be paid to the sharp corners of floor tiles, broken floor tiles, tools, etc., which are easy to damage the waterproof layer when laying floor tiles.

The bathroom itself is small and has many pipes, and more than 80% of the water leakage problems are concentrated in the yin and yang corners, through the pipes, sanitary ware, and floor drains, so these places need to be paid special attention to when doing waterproofing.

Here's how to do it:

1. Chisel the cracks and parts that need to be repaired such as the root of the pipe and the floor drain into a "V" shape, clean them, and sprinkle them with water to moisten them;

2. Add water (water-cement weight ratio 1:2 3) to the [permeable crystalline repair mortar] and mix it evenly, and carry out repair construction before the initial setting (within 5 minutes), and the root of the pipe, the perimeter of the floor drain, the yin and yang corners, and the root of the wall should be made into r angles;

3. After the final setting of the repair mortar, stir the powder and liquid material of [durable waterproof slurry] evenly, let it stand for 3 minutes, stir it again and evenly brush it on the base surface, and it should be cross-brushed twice, and only after the first surface is dry can the second construction be carried out;

4. Anti-stampede after completion, closed water inspection can be carried out after 48 hours.

As for the price, it will be affected by the economic level of the sales area, logistics costs and other factors, so it is recommended to go directly to the local building materials market to inquire.

You need to find a professional waterproofing company, because it's a hidden project, and it's hard to repair it later, and you can't spend a lot of money in the family.
