How to deal with the waterproofing of the balcony inner wall?

If it is a leak on the exterior wall, the effect of waterproofing inside the balcony is not big, and the problem is not big if you consider sticking tiles!

In addition, it is very simple to do waterproofing, just buy waterproof paint and brush it up, and the specific operation method is just as described in the instructions.

If you don't want to seal the balcony, you have to use linoleum, brush a layer of cold bottom oil, pave the linoleum felt, and the linoleum should be pasted on the wall at least 25 inside, and then draw a layer of asphalt oil, and then lay the linoleum again, and then you can do the decoration.

Waterproofing is divided into two forms, one is pro-(welcome) water surface waterproofing, the other is back water surface waterproofing, in terms of the cost of waterproofing and the effect generated, the water-friendly surface waterproof practice is better than the water-facing practice.

As far as you said, the main reason for the mold of the wall paint on the interior wall of your house is caused by water seepage on the balcony side, but the source of seepage is not the downpipe, and the water here may be the rainwater that falls to the balcony when it rains. If you have a washing machine here, also check the water supply fittings for leaks.

Waterproofing method: There is no need to do waterproofing in the room, if you have a washing machine here, you can chisel the exterior wall to a meter high, clean the wall and apply cement-based polymer waterproof paint twice (thickness mm); After chiseling off the tiles on the original floor of the balcony and cleaning it, apply the cement-based polymer waterproof coating twice (thickness mm). The junction between the wall and the ground, the corner of the wall, especially to do fine, do a good job of waterproofing, after the waterproof layer is done, plug the floor drain, fill the balcony (about two centimeters above the ground water) to do a closed water experiment (24 hours), if there is no water leakage, you can wipe the cement mortar protective layer, and finally paste back the tile (if the washing machine water supply pipe is to be buried, but also check whether the water pipe joint is leaking).

If the balcony floor is higher than the drainage floor drain, the upper part of the perimeter should be plastered with cement grout (or painted with waterproof paint) to avoid the seepage of the water edge mortar.

Generally, unlike the bathroom often soaked in water, I personally feel that the balcony does not need to be deliberately waterproof, if you have to do it, then use waterproof materials to brush it again.

Do waterproofing first, then lay tiles, and waterproofing inside is very simple.

The original wall surface is sanded smooth, and then brushed with waterproof paint and cement mortar tiles. That's it.

Waterproofing of the balcony.

1. The first waterproof gate is the doors and windows of the balcony. The quality and sealing of doors and windows should be good, and the inside and outside direction of the waterproof frame should not be mistaken.

2. The second waterproof gate refers to the waterproofing of the balcony floor. The first thing to do is to ensure that the ground has a slope. The lower side is the drain; Also, make sure that there is at least a height difference of 2 3 cm between the balcony and the living room.

To make the living room and the balcony have such a height difference There is a certain degree of difficulty, you can use a marble slab to decorate, and use cement to fill the leakage spirit at both ends of the stone slab and below to do a good job of plugging the joints and preventing leakage, which is both practical and beautiful.

3. The third waterproof pass is to keep the balcony floor drain unobstructed. On heavy rainy days, when the rainfall is greater than the drainage capacity of the floor drain, it is possible to form water on the balcony floor, and when the amount of water is too large, it is possible to overflow the waterproof frame of the sliding door and enter the room. Although it is unlikely, it does happen occasionally, so it has to be prevented.

4. If the balcony is to be slotted in the future, the waterproofing will be destroyed, and if necessary, it must be redone.
