Re-facing fireplace, several questions!


I personally don't see a problem adding the additional weight and the fascia to the existing structure. It appears substantial.

I'm not sure where/how the gravel's position relates to the main structure below in the basement.

Even at that. I am also confident the new hearth can be built basically as the old hearth was but I don't see the need for additional cinder block at that location.

Maybe others are seeing something I'm missing.

I have to admit, I've never seen anything constructed even remotely close to what you have going on. I have no idea why there is wood under the hearth at all, or why you would even want to use wood, on a masonry FP.

I'd start by tearing out the wood, verifying that the hearth extension is actually poured (it should be under the gravel & over the angled plywood form you see from the basement), and move on from there. When you have a solid masonry structure to build on & against, it just seems silly to layer in something as tempurmental & "temporary" as wood, especially on a wood burning fireplace...........

Yeah the wood's got me concerned too, all of it will be coming out.

So adding another layer of brick to the existing brick chimney with mortar/brick, then mortaring a layer of veneer stone to the new brick is ok right? Just want to make sure I am understanding you.

Is there a way to put something solid where the gravel is, so that I build a frame with either the steel studs or some brick to make the hearth? Is that normal where the plywood is in the basement, what's it there for?

As long as there is enough foundation/bearing present at the first floor level, it won't be a problem at all. I would suggest using wall ties into the existing block work (Tapcons generally work well here for fastening them in) to tie the new block layer in. Once the additional block is in, you can go directly over it with thin veneer stone. Just remember if you buil it out past the existing wall, you will need corners for the returns into that wall.

From the basement picture, it sure appears that the hearth extension is already formed for concrete. It may very well have a concrete sub-hearth in place already under the gravel. We'll never know though until you do some digging in the gravel.

It's perfectly normal for the plywood to be there, other than with current code, it needs to be stripped out after the pour.

I'd also suggest merely using concrete block or brick to form the hearth on top of the concrete sub-hearth rather than messing with steel studs.

Thanks!

I will tear out the existing hearth and the extra layer of brick surrounding the firebox and do some digging in the gravel to see what is under there once I get some free time

Quick question,

Anyone ever used spec-mix veneer stone mortar? Good/bad? Or just stick with standard type N mortar?

Never used it, but it shouldn't be a problem. It will probably be easier to buy a pre-mix product rather than sand & masonry cement separately.

Did you ever find concrete under the gravel on the hearth extension?

Thanks!

Going to use the spec mix mortar for scratch coat and also for applying the stone.

There actually was concrete under there, but only to about 4"-5" below the level of the hardwood floors. I built a form with 2x4s and poured concrete to the outside of it (cut out some weight rather than pouring the whole thing). Then I built a hearth with 16g steel studs and anchored that down to the concrete. Then 3 layers durock on top, metal lathe and scratch coat to the sides. Picking up the bluestone slab today, and also 50sf of veneer stone.

Good work and it's always nice to see a project finished on here...........

It looks like you went with a natural thin veneer stone vs. the cultured stone??
