Can anyone tell me whether it's necessary to remove the plywood supports after the hearth has cured or can I just size the plywood to overlap the concrete blocks by a few inches, position some middle supports and then frame only around the outside of the blocks? Is there any specific reason not to do so?
As well, does anyone know if fibre-reinforced concrete is a reasonable option for the bottom layer of the hearth? Someone suggested it would be better than regular concrete due to our harsh winter climate but I don?t have a clue if that?s correct.
Thanks,
Sarah
