Hi. Ben here from Yorkshire UK. Just starting my oven build. I have the base constructed and have just removed the shuttering on my slab.

I am about to assemble the precast oven pieces and was sent 2 tubes of this (pictured) I am assuming this is for the locking joints of the oven sections? I was planning to leave the floor tiles loose but expect I'll need to bond the dome sections together with this stuff.

Massive newb Q, I know!!

Thanks
