I'm trying to mount a 55" tv to a wall in a Seattle apartment, using the heavy Sanus BLF228. Using a stud finder, I'm finding a weird pattern for the studs (pic: http://ift.tt/2w4fDP6).I looked this pattern up online, and it looks like a staggered stud pattern. The problem is when I drill into the wall to test a stud and find its edges, the wall feels the same at every point, even in the exact middle between any studs.The drill easily makes its way 0.5" in, then it hits something harder, but continues to go in with pushing, at least up to 2" deep. It seems to do this regardless of where I drill. Has anyone encountered this? Is there just a giant sheet of wood behind the plaster? Or is it something weaker? via /r/DIY http://ift.tt/2uKv0fD
