Because I am fitting a woodburning stove onto the hearth in my 1930's semi it seems the only surefire way to ensure the chimney breast surface doesn't blow/ crack or fall off is to have it rendered with a sand/ cement and lime mix.
I assume 2 coats will be necessary and I need to add lime, but which one? Hydraulic, non-hydraulic, NHL2, 3.5, 5.....................help me I'm suffering from lime overload!
