/diy/ - Do It Yourself

Looking to fix some cracks on some old walls. First time doing it so I was looking for pointers. Is it as easy as it looks or nah?

Basic understanding is that you open up the crack a little bit so the adhesion can do it's job better.

Then apply apply some joint tape over the crack.

Then spread some joint compound over the crack and tape. Pic Related.

Wait for it to dry (I've never been told how long it takes to dry).

Apply second coat, spread out a little more. Wait to dry. (Around an hour the second time)

Apply third coat. Wait to dry (around an hour for the third time)

Sand it down with a sanding block. Clean up and basically ready for paint.

Am I on the ball? Anything I need to keep in mind? Is there a better way?
