Hi,

We had a hole in wall in out garage wall due to someone not stopping the car in time and hit the wall and the fender made about an18x8 indentation.

My 2 sons decided they wanted to go to store, get the patches and fix it themselves.
So they went to Home Depot and as usual there was hardly no one in the store to help. I have the same issue when I go there and you'd think they were in bankruptcy or whatever.I understand they are a do-it-yourself store but recall they used to have buttons in the aisle which would make an announcement for someone to help.

So any way they bought 3 size multi-pack of HDX wall repair patch and Alex Plus spackling, and used 2-8x8 patches next to each other.
They they applied the spackle and kind of enjoyed playing with the applicator but I told them to read the instructions. I also told them I would try to get some advice here for them.

So I an curious how should they proceed-should they use sandpaper around the edges or is it too late & they should just paint?

Thanks for your input..

 

Did they remove the busted drywall or, as it looks, put some type of patch over the drywall?

Hint, old drywall should have been removed, new drywall patch installed, taped and mudded!

 

Do you want it to look new and finished or just patched and left like a patch on a different color?
you can leave the old drywall as long as it's not sticking outwards. But to finish it properly you need some drywall compound and some drywall knives to smooth it out. Do a full layer, another skim coat, sand.
the final coat will be around 8-12" past where the patch is.

 

It looks like the patch protrudes out from the rest of the wall. If so you'd need to sand it down, flush if possible otherwise you'd need to feather the repair out further so it won't be as obvious. Spackling is for minor repairs, joint compound should be used for anything bigger than a quarter.
