Hey, in desperate need of advice!! I've searched the Internet and found loads of info on concrete vermiculite mixes, what I need to know tho is can I make a motar mix for laying bricks with vermiculite in, if so what ratio sand cement vermiculite?? I'm using it to build a brick hearth. I've got a big bag of very fine vermiculite. I've also heard that you can supposedly use vermiculite in plastering on chimney breast to make it heatproof and stop it from cracking and blowing,, I don't know how true this is nd if someone's just telling me tall stories?!! Any and all help with this would be really appreciated.
Thanks in advance
Sean.
