1. There is a gap between the window frame and the wall.

On the one hand, it may be caused by the unqualified quality of the window itself. For example, windows with poor quality may be easily deformed; On the other hand, it may be a construction problem, which leads to lax sealing or cracking. In this way, the rain will seep in along the gap in the windowsill.

Solution: first clean the cracks and tick off the joints with weather-resistant structural adhesive, and then wait until the next rain to see if the situation has improved.

There is a gap between the glass and the window frame.

Sometimes, if the glass on the window is not tightly sealed with the window frame, rainwater may seep in and soak the wall.

Solution: Reinstall the sealing strip.

The windowsill outside some old houses may have no slope.

Now in many families, you can pay attention to it. Generally, the outer window sill is slightly inclined downward to facilitate drainage. If the slope of the window sill outside the house is flat (even inclined inward), it is easy to seep into the house when it rains heavily and other possible minor problems are added.

Solution: replace the window of the old house, and suggest that the inner windowsill pad is two or three centimeters high.

4. There is no drain hole in the sliding window.

In some families, the bottom of the window may not be fixed, but the sliding of the window. As we all know, the chute is also a groove. When it rains, there will be water inside. Generally, sliding windows will have drainage holes, and water will flow out. However, in some families, the sliding window slide has no drainage holes. In this case, if the accumulated water diffuses into the room, it will also cause the inner wall to be soaked.

Solution: First, check whether the sliding window has drainage holes or whether the drainage holes are blocked by dirt. If there is no drainage hole, you can find a way to open a drainage hole yourself.

5, waterproof layer problem

Various methods have been tried, so it may be the waterproof layer. In this case, it needs to be waterproof again, and of course the price is relatively high.

Solution: Knock out the width of 5- 10 cm from the inner corner of the window sill (the width varies from place to place) until it touches the fine stone concrete. After cleaning, brush a layer of leakproof paint first, and then brush waterproof paint after drying.

How to make windows waterproof?

1, the waterproof work of the window is mainly to waterproof the window. After scraping waterproof putty on the wall, apply waterproof coating. Generally speaking, foundation construction should be done well before windows are waterproof, which can enhance the waterproof effect of windows.

2, the window waterproof, first of all to clean up the windowsill at the grass-roots level, clean up can show cement mortar at the grass-roots level, and then remove the sealant at the bottom of the window, and then stick it back for sealing. If cracks are found in the windowsill during construction, it is necessary to repair the cracks in the windowsill with plugging treasure and find a slope outward to facilitate rainwater drainage in rainy days.

3. After the plugging treasure is completely dried, waterproof coating can be applied. In this process, we need to use two waterproof materials, one is the bottom material of mortar, and the other is high elastic acrylic material. Bo Tu should be made when painting, and the next layer should be painted when the previous layer is dry.
