I am redoing my house and some rooms have some kind of drywall(think it's called blue board, 12" wide strips) nailed to the walls and then a 3/8" or so layer of plaster. I need to patch some holes where I took a wall out. What is the best way to patch these?

Can I just patch some drywall in the spaces and then tape and mud them? Or do I have to use plaster? Also there is some spots that just need a "skim coat", can I just use mud on these or do I need to use plaster?

Never delt with plaster before so if I am going to need to any tips will be appreciated. Thanks.

Blue board is what is used under a modern plaster finish. Yes, it can be patched with standard drywall and mud.

Thanks bill. I was hoping I could just use regular mud since I've never used plaster before.

The stuff in 12" wide strips is called rock lath. It is pretty much like drywall, but was used as a base to plaster over. You can use 3/8 or even 1/2" drywall to patch in and cover it with drywall compound. It's usually easier to shim your patch to match the surface of your plaster and then tape the joint and finish like you would drywall.
