perlite -portland mixture for oven floor

Miki,

There's no reason to stop now in your location. The only time you do is when freezing temps are forecast. In your neck of the woods, that's probably not until mid November. Fresh mortar cannot be allowed to freeze, and it takes 28 days to cure.

I'm glad you got it done.

Too bad the weather is changing.
It's still in the 90's here.

It doesn't look like winter is coming here this year.

Hey Jim,

Did I do something wrong with my calculations?

He ended up needing 6 bags of perlite....

Just curious.

Jim, what about insulating blankets? The ones used to keep foundations warm after pouring during winters? Would that keep one working, or is it too risky?

Allow me to re-phrase the question. If fresh mortar is not allowed to freeze, and it takes 28 days to cure, how long after using the mortar can freezing temps be tolerable? Anyone?
