Sealing the balcony is divided into two kinds, one is to decorate the balcony, the other is to simply change the window to seal the balcony, first say the first one, if it is the decoration of the balcony, the balcony must be scraped putty or tiled before the balcony, at the same time, the waterproof glue only hits the outside, not the internal waterproof glue, because it is a rough wall, it can't be sticked, and at the same time it needs to scrape putty, so the interior can not be played. The other is to only replace the window to seal the balcony, which needs to be sealed with waterproof glue inside and out, so that the window and window sill can be perfectly combined.

The waterproofing of the balcony is mainly reflected in the gap between the balcony window frame and the wall and the window glass, which depends on the workmanship of the balcony window and the use of waterproof adhesive. As far as balcony windows are concerned, the first thing is to pay attention to the quality of the broken bridge aluminum window, the sealing should be good, and the second is not to make a mistake about the inside and outside of the waterproof frame. After the balcony window is installed, there will be gaps between the structure of the window and the local area where the wall touches, but this gap must be within the promised scale. Of course, if the gap is too large, the window scale is too small, and then how to fill the gap with glue, it will feel tight, but after a period of time, the glue will be shortened through long-lasting sun exposure, and then there will be a gap again, which is also an important factor in the leakage of the balcony. >>>More
