I would do a California patch. It is MUCH easier and a lot more forgiving.
- First square up the hole.
- Then cut a piece of drywall the same thickness as the hole, 3" wider and 3" taller than the hole.
- Turn over the patch piece and score about 1 1/2" in from the edges with a utility knife. You are not going through but just scoring the paper to the same size as the hole.
- Now carefully fold back and peel of the drywall part at the score but leave the FRONT paper intact. You do not want to mess up the front paper but remove the rock part behind it. After you do one it will be easy!
- Now you have a piece of sheetrock with the front paper sticking out 1 1/2" all the way around. Test fit into the hole to make sure it fits OK.
- Put joint compound on the edges of the hole, also on the face of the wall out at least 2" and about 1/16" to 1/8" thick. Install the patch piece and using a 6" taping knife, squeeze out all excess joint compound. Let it dry for a few hours or until all white.
- Do a couple more thin coats around the edges as needed until smooth with the rest of the wall, and your done!!
- Lightly sand, prime and paint !!
I used Joint compound above for clarity but instead of joint compound I would recommend using Durabond 90, it dries faster and will not shrink in the space, get it at the hardware store and pick up a small painters pail to mix it in, Water and powder, very easy, needs to look like oatmeal without the lumps.
It sounds harder but you will never get that patch to look right by spraying foam in the hole and trying to mud over it, it will take a week to dry and will always look sunken in and the first time someone hits that spot with anything it will crumble.
