I have a fireplace 18 feet high. I want to stone it all the way up. Any suggestions on how it is applied to drywall. And second the side walls are on a 45 angle. Best way to do it. Thanks

You will have to use Cultured or faux stone. Chances are that there is inadequate footing to use real stone and most likely will be cost prohibitive. You will have to prep the wall with either plywood, wire lathe and parge or attach a concrete backerboard and parge. Stone will never hold on drywall. There are several manufacturers of cultured stone with a large varities of type and color.
Thank you so much. Would u have to mite back each corner because the corner is all a 45?

A second reason for using cultured stone - you can get outside corners for both left and right.

i installed faux stone on my fireplace..few years back this is what i did found the studs behind the sheetrock nailed up tar paper to the wall installed "chicken" wire to the wall small 1/4" holes in wire....used for stucco did a scratch coat over the wire installed the rock..i used a 2x4 over the fire box opening to support rock during installation.. on the gas log lighter..i used a 3/4 pvc pipe as an extension to move the esction out grouteed inbetween rocks by hand...

The corner stones are 90 deg so you may have to be a little creative. The corners should alternate with every other course with the long side of the corner piece.
This is one approach just using flats and no corners on an angled portion
Will it hold? Given that method it is only as strong as the paint on the wall. Which in reality that is what is holding the stone up. Or if it is unpainted drywall then the paper of the drywall. Remember you are putting a wet thinset on paper. Not to be critical of the video I would just like to point out a few things. The firebox opening to make it look authentic should contain a "keystone" and soldier course. The cut ends of the filler stone should never be placed in the center of a course but to the outside edges. When cut the end of the stone does not look natural as the factory edge. It is doubtful that you will be able to percisely lay the stone horizontally without making cuts. But do so that they are not as noticable. Meaning put the cut pieces to the outer edges and alternate sides with each course so that you will not have all the small cut pieces on one side. On your ledger board ( above firebox opening) find a board of sufficent width to match the width of the stone. Too wide and there will be a gap. Too narrow and you will have to cut the stone width down.
Thanks Frodo for posting. . .
