Hi all!

I finally have the frame completed and am hoping to start the pizza oven asap.

As I dont require a cement base I was planning to put sheet metal ontop of the metal frame and poor the vermiculite+cement mix. Am i correct in assuming this would be the correct method?

Also which vermiculite would i use. G2 or Fine Vermiculite, G3 or Medium Vermiculite,
G4 or Coarse Vermiculite.

The top of the pizza oven frame is 50x50 angle iron which is 1.3/1.5m so ill require 97.5 litres of mix.

I have been given 50x50 rebar mesh.. would this be required or have no real benefit?

Any help appreciated!
