I am new at home repair and I tried to attach a new flat screen to my wall.
The apartment is very old and where I went to drill was like drilling into sand. The final hole diameter was supposed to be 10 mm so I drilled first a 6mm pilot hole.....which ended up being 10mm!
Once I started to fasten, the wall just fell apart!
Was it me? Or is the mortar just to weak? The mortar was about 2 inches deep before I hit solid wall.
Any help would be appreciated!Thanks!
