Hi, dh has been trying to mount a tv bracket on our wall. After multiple attempts and changes of height due to bad walls we now have About 12 holes in the wall and no where left to mount it. He tried poly filler, grip filler, rawl plugs, long screws and metal rawl plugs you name it. I feel so upset because now we have a giant tv on floor that can’t go up and can’t go on stand. I have a young toddler and need this sorted out. What can we do??
