Its been about ten days since I poured the structural hearth. Now finally my vermiculite has arrived. My question is with this 10 days inbetween the pours do I need to do anything to prep the set concrete of the strucural hearth. Also is it ok if I do half of insulating hearth pour today and the other half tomorrow. Any need to keep it damp after the insulating hearth pour is complete?
