Mounting a TV in unknown wall material
We just moved into a pretty old house and I want to mount my TV in the wall, I'm just not sure what the house is built from and how to find the studs. I drove a short nail in a lot of different places. About 3/4 inches in, I kept hitting something that seemed really solid, like I would be able to mount my TV on. However, I kept hitting it everywhere I ran into, so I'm assuming its not the studs. It's a 32inch TV, and I'd love to know how to find the studs and what's going on behind the walls, I'm assuming its plaster. THANKS!
