What should I do if the bathroom leaks in the old house?

What you said is to solve it in two ways.

First, the exterior wall is waterproof.

If it is water seepage, then the exterior wall waterproofing must be destroyed, which is somewhat difficult to deal with, so you can do an architectural waterproof layer at the indoor wall foundation level, and then use plaster, putty, etc., and finally use paint and the like, because the base layer is to remove the overall putty and directly manifest on the cement surface. This coupled with indoor waterproofing can be used for about ten years.

Second, the interior walls are waterproof.

Nowadays, the form of base film is used, which is very common in the market.

However, if you want to completely solve the problem, you still have to deal with it from the exterior wall, if it has nothing to do with the exterior wall, because some are bathroom or kitchen walls, then as long as you do a good job of waterproofing, and finally use a good waterproof wall lining after doing waterproofing, I recommend using the primer, because it can resist alkali and yellowing.

1: There is water on the upper wall near the package riser, which may be a leak in the upper layer; It could also be that the upper layer leaked and leaked down the pipe.

2: There is water on the lower ground near the package riser, which may be the upper layer leaking down the pipe, or it may be the problem of the household riser, the joint, the valve, the cleaning port, etc.

3: Other walls are flooded by the top, and the bottom of the roof is flooded, which must be the reason for the upper layer.

4: The water in the ceiling may be caused by the ground on the upper floor, or it may be the leakage of the pipes in the ceiling of the household (the sewer pipes of the household and the upper floor).

5: The middle of the wall is leaking, and the most likely is the leakage of the buried pipeline in the wall.

The old house is prone to this phenomenon for a long time, my house has lived for more than ten years, before it has been good, on last month suddenly downstairs neighbors knocked on the door, to the bottom to see that the leakage is also very serious, and then went to the side of the road to find a repair, repaired for about a month, the result began to leak again, and I can't see the person who repaired me.

Later, I heard from a friend that Qingdao hairy ants are very reliable to make bathroom waterproofing, which is considered to be good, water leakage is really a troublesome thing, and you must be careful when repairing.

Smearing waterproof cement quickly and very effectively.

Go to the upstairs bathroom and re-turn the warehouse to do waterproofing, and then repair the bathroom on your floor.
