FAQ
Does the calculator distinguish between internal and external plaster thickness?
Yes, external plaster is often specified at a different thickness than internal plaster, partly because external walls face weather exposure and sometimes need a richer mix or waterproofing additive, so the calculator lets you set thickness and mix ratio independently for internal and external walls rather than applying one assumption to both.
