Hi, my suggestion may not be what you want but I had my brick fireplace before we installed the wood floor. I didn't like the look of the wood abutting the brick so my DH got quarter round molding and installed it (even around a slight curve) and I mixed up some paints to the exact color of the bricks and painted it and then varnished over the paint. I painted it before he laid it in. We had a floor may from Lowes here today to measure for a new floor and he asked where we bought the custom trim, he'd never seen such a good match to brick lol. It's an easy thing to do, I used acrylic craft paint.

Well, it's a little late for that. I did purchase some 1/4 X 3/4 bullnose strip molding that I'll use. I've already matched the color. Undercutting the brick would have been the proper way to go. According to my wife, we're going to reface the fireplace in stone anyway. Thanks for you input!

What about putting a 3/4 inch (or whatever the thickness of your flooring material) piece of bluestone or other type of stone "skirt" around the floor. this would give you a straight edge to bring the flooring up to (leave an expansion gap). You could then use T molding on the seam and grout the gap between the skirt and the stone. If you made the front piece wide enough, it could act as additional floor protection from stray embers.

I used Duraflex molding sold at Amazon. No way I was cutting my fireplace.

It came out pretty good, I used clear caulk type adhesive, and concrete repair caulk (color matched the mortar on the fireplace.)

And now 6 years old post, wtf?
