<< You have been told how to fix it. My advise is to quit punching walls! Very bad habit. You get carried way sometime and connect with a stud you could break a hand. Just don't, it's a dumb thing to do. >>
Yeah now you tell me 🙂
In HS my stress release after bad tests was coming home and putting my fist through the drywall in my closet. This was all fine for the first 31 punches. On number 32 I got a little to excited and missed!
Yep, mr 2x4 was right there. Took out my 4rth metacarpal. Hurt like a SOB! Anyway, moral of story is don't punch walls unless you know exactly where the beams, electric boxes, pipes....
If the hole is connecting (you broke through the drywall, you would have to buy some plaster mesh (cheap) and plaster over it so the plaster doesn't get sucked into the hole. Then sand if off and repaint with same roller type. Have fun 🙂
