The ground of the bathroom should be waterproofed, waterproof, filled with toilet water, 36 hours to let the downstairs inspect, and then play cement tiles, after tiling can not sprinkle water, and wait for the beauty of the seam to dry after use, and the wall has nothing to do with it, but generally tiled, the wall, the ground is pasted together.
There are two reasons to come.
One is the tile source. >>>More
Is there a water stain on the other wall? That's because the waterproofing is not done properly. Waterproof to make less to a meter high (preferably to the top), and leave no loopholes. If you don't want to redo it, don't drench it on the wall again, and it will be better to hook the joints with weather-resistant glue.
First use a nail and a hammer to make a small crack surface on the tile surface (seam) to be punched, very small, so that the impact drill bit positioning, the impact drill should be slow first and then fast, and the depth is determined by the length of the collision bolt.
