3/4" Plaster On Block Wall

Best way to build up plaster to a thickness of ¾+ inches?
Had to remove some of the plaster and metal mesh during remodel, gap is from floor to ceiling, about 4 to 6 inches wide and existing plaster is about ¾ inch thick. The plaster is on a block wall and will inside corner to new drywall. Can I get away with steel mesh corner and multi coats of compound or would plaster be better to prevent cracking?
better yet is there a fancy new spray that will fix, feather and sand?
Any info would be great.
Thanks, john

Re: 3/4" Plaster On Block Wall

Probably the easiest thing to do would be to get a piece of 5/8" dry wall and cut a piece to fit the hole. You can use construction adhesive to hold it to the brick, tape the edges and then skim-coat the additional 1/8".

Bond the brick and plaster edges with bonding agent. Mix the gypsum plaster a little thick pack the hole and slick it off with something thin and straight (I use a piece of cedar siding) let it set. Finish with plaster,water trowel it.Give it about 2wks to dry real good,prime paint done.
Hope this helps it's not as hard as it sounds.
