Anonymous users2024-01-24I don't know where the location of the hole you said is, is it very conspicuous? Is there anything else around the hole? What is the height? How many holes are there? How is it distributed? Are there tiles on the walls?
If it is not conspicuous, just plug it with white cement.
If it is conspicuous, if it is in the right place, use the original hole to install hooks, shelves, mirrors, decorations, etc.
It's basically about finding something to cover.
You can decorate it from the outside, and you can build it with the murals on the wall.
Redo waterproofing The others are palliative, not curative.
Expansion screws for M6At least To make a hole 6cm deep.
Regardless of whether the expansion screws of your house have penetrated the roof board, as long as the waterproofing of the upstairs is done, there will be no water leakage. Only if the upstairs is not waterproofed will there be a source of water leakage. There should be a gap between the large expansion screw and the roof slab so that water will leak down the gap.
Bathroom punching should be divided into ordinary walls or tile walls If it is an ordinary wall with an electric drill or impact drill, if it is a tile wall, it is best to use a professional punching drill bit, and it is best to use a special drill bit for tile punching on the tile wall, do not directly use the impact drill bit electric hammer to punch the hole, so that you can 100% avoid the tile being cracked, you may see others are directly punched with an electric hammer, and the tile is not cracked, the important reason is that the tile is not hollow at the location of the punch; The sound made by hand knocking on the tile can tell whether the tile is hollow, if there is a hollow drum or you can't tell whether it is a hollow drum, be sure to use a special drill bit for ceramic tiles to punch holes.
