Heat stop

[Les]

I just got a quote for a 50lb bag of heat stop - 300 plus dollars!!! I'm thinking that's pretty absurd.

You can get it shipped to you for less that that for sure!

Try the rumford website at HeatStop
They list it for $50 plus $35 shipping. They also have a dealer in Carson City - Carson Masonry that you could try.
By the way, I'm planning on a 42" and will taper the bricks to reduce mortar usage, I was wondering on how many bags I may use?

If you can get it locally, you should buy one bag at a time because it does have a tendency to wick out humidity and develop lumps. I used one bag, but I cut everything. A semi cut oven (brick sides cut, but not tapered) should use two or three, depending on how deep you lump it up. I don't think you need to mortar all four inch depth of a half brick oven, in other words leave it a little porcupine like.

Thanks RC - Carson Masonry is where I got the absurd quote. I’m thinking that it was for a pallet or a larger quantity. Or they may be running with the Barnum and Bailey mantra. In regard to how much we need, not sure. I was going to buy two bags and go from there.
