Hi, I'm making a tile covered cement hearth (back and front hearths). The
wooden floor (over a cellar) level needs to be raised 3 inches to match
the other floor levels. The wooden floor goes right up to the fire place
opening (no constructional hearth).
I'm raising the floor level by battens then chip board flooring.
1. do I raise the floor then make the hearth - approx 2" high plus tile.
2. make the hearth first - would be approx. 5" high plus tile thickness.
3. is it ok to put some plastic sheeting etc. under the cement hearth to
protect the wooden floor?
