How to consider the waterproofing of decoration and hydropower transformation?

Step 1: Primary treatment

Before waterproofing, the base must be cleaned up. After all, waterproofing can be understood as a film covering the base layer. If the foundation is not done well, the waterproof effect is definitely not good.

Smooth, there can be no trachoma on the wall. If it involves reforming the pipeline and changing the launch site, it is even more important to pay attention.

The horizontal and vertical internal angles should be made into circular arcs, which are not shown in the figure.

Pay special attention to the waterproof treatment of the intersection between the root of the sewer pipe and the ground. The protective film at the root of the downspout must be cleaned. Otherwise, the waterproof paint at the root is brushed on the protective film, and water will flow downstairs from under the protective film.

It is right to remove the protective film from the root, but there is something wrong with the practice of hydropower.

Step 2: Brush waterproof.

Brush the weak parts such as drain, floor drain, yin and yang angle first. Then start the overall waterproof coating, first the wall, then the ground, and retreat from the inside out.

When painting, you should draw up and down first, then draw left and right. The thickness of different waterproof materials may be different, so you should determine the thickness according to the waterproof coating you choose.

After the first waterproof drying (curing until it doesn't stick to hands), you can start the second brushing (you can also do the third brushing if possible).

As for the height of the painting, it is said that "the waterproof floor of the kitchen and bathroom is all made, the 30 th floor is turned up, and the shower room is 1.8 meters".

Do you need to explain everything on the ground? The so-called 30 fold means that the wall must be waterproof again, and the shower head 1.8 m, which means that the waterproof height of the shower head wall should be 1.8 m.

Step 3: Closed water test

After the waterproof brush is finished, we can start the closed water test we mentioned at the beginning.

Step 4: Tile.

After the closed water test, you can start tiling. When the kitchen and bathroom are tiled, if there is a floor drain, you must make a slope to the ground to let the water flow out smoothly through the floor drain.

Friendly reminder: when paving floor tiles, when paving the threshold, brush a layer of waterproof paint on the cement layer below the threshold to prevent water from leaking out through the cement layer. If it's the floor outside, it's easy to leak out from here and make the floor bubble.

It is also recommended to coat 20-30cm waterproof on both sides of the door cover, which can reduce the moisture regain of the door cover to some extent.
