After listening to the master s words, I really regret it, the balcony is sealed first for home deco

When pasting tiles first, you must use a level to find the horizontal line out, and then paste it according to the horizontal line, and it should be low on the outside and high on the inside, and a drainage slope should be pasted out, and the mortar under the tile must be high, and it should be solid, and there should be no gaps, so that the tiles are not easy to seep water. After the tile is pasted, you can seal the balcony, install the balcony frame, seal it with waterproof and weatherproof glue inside and outside, and finally install the glass, so that you can basically do it foolproof. In special cases, the balcony is sealed and tiled first.

Some balconies are high on the outside and low on the inside, so it is easy to accumulate water when it rains (the water cannot be drained out, so it may seep into the water), which is called back-watering. In this case, it is recommended to paste the tiles first, and repair the situation of high on the outside and low on the inside when tiling, so that after the balcony is sealed, there will be no water that cannot be drained.
