another hearth question

Re: another hearth question

Thanks for the advice. If I can, I will do both tomorrow. Originally, I was not going to begin this project until May, when I start my 3 week vacation. I ended up starting sooner, working every weekend. I figured if I can finish the oven before I start my vacation, I can relax for 3 weeks and eat lots of pizza, instead of work my tail off. Good luck with your project badger.

Les isrigh. The plans called for everything to be poured at once (same day). But most seem to do it in two parts. I just poured my hearth yestarday and will pour the insulating layer next weekend. I think the concern was you didn't want a "cold joint" but given the weight of the oven - nothing is going to shift.

Re: another hearth question

I recall that the plans wanted you to pour them together, I really don't think it would matter either way. Most of us have gone to the insulation board for simplicity - sounds like you are committed, so go for it. Good luck and welcome to our obsession.

Hello everyone. I hope you're all having a good weekend. As for me, I have been busy building my oven. I have just poured concrete down all of the block wall cores, and have framed for the hearth, using 2x8's. The rebar is all set for the structural layer also, which I plan to make 3-1/2 inches thick. The insulating layer will be 4" thick, made of portland cement mixed with perlite.

I am following the FB plans for the Pompeii oven 42". I am not quite sure of the process for pouring the two layers for the hearth. Once I pour the structural layer, can I immediately start with the insulating layer, or do I have to wait a few days for the structural layer to cure?

Thanks in advance for any suggestions.
