1. I cannot easily obtain fireclay. Any recommendations instead of the sand-fireclay mixture for the underfloor paste? I was going to use either plan sand or a thin layer of Refmix mortar.

2. Any objections with using Refmix mortar in construction of the vent, chimney, and openning arch?

Hey Jeff,

Refmix will be perfect for the vent, chimney and opening arch. That area gets hot, so using a high temperature mortar is the right thing to do. Plus, it has a nice, fine grey finish, so it will look nice.

I don't think you need to go to the trouble or expense of mortaring down your floor bricks. If you can't find fireclay, you can use a bed of fine sand and tap your floor bricks into place with a rubber mallet.

Would other builders agree with that?

I also found that by time i cut all my bricks in half, i had more than enough dust/sand for underneath the hearth. i still have a bag left over. But it would be a long drive from Calgary to deliver it to you )
