Chimneys & Fireplaces Question
Dpm under hearth?
I removed the old hearth and need to put a new one as somebody is fitting a wood burning stove soon. So two questions
1 there is damp on the chimney floor, do I ignore and put the slate on top or do I put some sort of dpm and then new hearth over? (would liquid dpm be ok?)
2 somebody said that to put down the slate I need a loose sand and cement mix... could anybody clarify on proportions?
treat the floor with liquid bitumen first, when dry lay the slate on grit sand and cement mixed at 3 sand to 1 cement full bed semi soft so the slate will adhere properly
