I have a home that is cinder block construction. Inside is sheetrock over insulation secured horizontally with strapping. I want to install crown moulding to add warmth to my rooms, but finding anything to nail the moulding to is nearly impossible. Does anyone have any ideas? I though of some sort of heavy duty adhesive, but don't know if that would work or what kind to buy. I'm a single mom raising my granddaughter so hiring a contractor is OUT of the budget.
