Water seepage on the top of the balcony is not a common part

First clean up all the original filling, close it with a small amount of expansion glue, close it again with plugging spirit on the surface, and close it again with sealant for all sealants, it's almost the same.

First cut a crack in the outer window that is 1 cm wide and 1.5 cm deep, and then clean it and sprinkle some water to soak it thoroughly. Fill it into putty with the plugging king, smooth it and sprinkle some water to prevent cracking after drying. After finishing, apply two to three more waterproofing paints, using the very flexible kind.

Processing steps: First, clean out all the original fills;

second, seal with a small amount of expansion glue;

Third, the surface is closed again with plugging spirit;

Fourth, all closures are closed again with sealant, taking care to do both inside and outside.

Here's how:

First of all, the balcony leakage should be found first, mainly from the high of the roof to the low place, because the water flows to the bottom.

Look at whether there are cracks in the roof, whether the original waterproof layer has aged off, and whether there are bubbles in the original waterproof membrane of the roof.

There is also whether the gutter on the roof is blocked, in the countryside, there are still a large number of tiled houses, when there is a roof leakage due to tile breakage, just replace the tile, this step is also called "leakage".

Secondly, if the roof is only the original waterproof, you only need to remove the leaking part 2 75px deep and clean it, you use asphalt to water it, and now there is a finished asphalt coating film, and when it is sunny, it will basically not leak.

If there is a waterproof layer, it is more troublesome, to remove the waterproof within the surrounding area, re-do the waterproofing, and pay attention to the original waterproof junction to do a reinforcing layer.
