[BlindHandyMan] knowing what your walls are made of? And filling up wholes in your wall?

[Blake Hardin]

Hi, ok what is the difference between dry wall and sheetrock? Or are
they the same thing? Also, a room that im in has quite a few wholes in
the wall and i was wondering how do i go about fixing them? I know you
can use sheetrock mud and patch them up but how exactly do you do it
step by step? Do i just buy the mud if thats what its called, spread
it throughout the wholes as evenly as posible, then wait for it to dry
and take a piece of sandpaper and sand it down to be even with the
rest of the wall? I know that after its done you have to pait over it
but thats fine with me because this room needs to be repainted anyway.
