How to fix patch this hole.





I need to install an under cabinet hood.

https://www.amazon.com/Broan-413023-.../dp/B000UW20OM

I'm going to close this hole and use a non-ducted hood primarily because the holes do not line up and I'd rather not get involved in more vent cutting.

In order to seal this hole, can I cut the drywall in front of the vent (without cutting the vent) until I got to the studs to the left and right sides of the hole?

If I cant get to the studs without cutting the vent, I was thinking of doing the following:

What do you guys think?

Also, which drywall thickness should I use? Or do I simply just measure the existing drywall and buy the same?

That is what I'd try, duct looks to be between the studs.

It's going to be pretty much covered with new vent so how finished the repair is will be up to you.

For patches I use matl that is 1/8" thinner than the wall that way I never get a patch that is too thick, just an extra coat of compound to finish off!

While it's a little large to patch it like in the video that will work and it doesn't matter much what thickness you use doing it that way. Another option would be to screw some wood [1xs or plywood pieces] to the back of the existing drywall with half of the wood showing in the opening. You'd then screw the patch piece [right thickness or just shy] to those pieces of wood.

Are you referring to cutting the drywall (to the left and right) without cutting the vent until I can expose the studs?

The new vent is much more compact so the bottom half of this existing hole is going to show.

Just realized that its going to be exposed to a lot of steam. Should I use green board?

Gotcha, so kind of like what he did in the video but instead of the wood just being a back stop, I would actually screw the drywall into it.

Unlike the video, the 1xs or plywood wouldnt be vertical in the middle but on the edges essentially mimicking a stud.

This may be the way to go since the drywall screws holding the wood will be further reinforced by going thru metal.

regular drywall should be fine if you prime and paint it
