Concrete block wall construction - siding techniques

[Stephen Camardo]

Hi - I'm looking at 2 properties to re-hab which are concrete block exterior walls (in one case 2 story, the other 1 story). One of them has stucco siding, which is "dated" in New England - the other is vinyl.

Question - what is the property "construction technique" for applying either say wood clapboard or cedar shingles over concrete - do you "strap" the concrete with wood - or, are say "concrete nails" sufficient" - also - what is standard for the interior walls - screwing a 2 X 4 against the wall (at 16" intervals) and then sheet-rocking over that? looking for some ideas to make construction estimates.
