Do not grab onto the tape measure when marking the holes in the tiles. "They will mark themselves" - There is 1 secret
I came up with this method when I hung a massive headboard separately from the bed on the wall. The suspensions were hidden from view, I was worn out until I figured it out. Then I hung up the shelves and the like like that, but I'll tell you about this later. The method turned out to be universal, which was suitable even for marking holes on tiles.
We mark the tiles
I recently made a kitchen, it was necessary to lay out an apron, it should have 2 overhead sockets, it is necessary to drill a hole for the wire.
Since the installation has already begun, a ready-made tile adhesive solution is available. It is enough for them to smear the place where the wire exits from the wall, and attach the tile with the back side at the place of installation.
For a couple of seconds, there is an exact place for drilling, the tile seems to have marked itself out, it remains only to drill. You can also grease the socket if the socket is internal.
Last year I marked the places for connecting a mixer in the bathroom. There, instead of glue, I used toothpaste, applied it to the plugs, and placing crosses, leaned against the tile in fact. As you can see, everything worked out exactly.
How to mark the location of furniture anchors
We hammer small carnations into the hidden suspensions at the very top, smear them with toothpaste, and using a level, we lean against the wall. Then we fasten the anchor according to the marks, and that's it!
