Hello, I\’m renovating an old sunday school into a home. I\’m taking all the old concrete and lime off and taking it back to the stone to get rid of salts and to let it breath. The outside will have the concrete pointing dug out and then re pointed in lime in April next year too. I need to re do the inside of the external walls to meet building regs and to build up thermal mass. It seems like a minefield of products and I wondered if you had any advice on this?
