stucco & drywall patching

I know NOTHING about the building industry, but we have very little drywall in the VI.

what kind of finish are on interior walls? exterior must be stucco.

Preferred building material is either poured concrete or concrete block. Interior walls are the same with some type of, I guess, stucco finish also. Somebody HELP me!!

Our new place on STX is mostly poured concrete and concrete block, with a plaster finish inside and out. That's for hurricane and earthquake considerations (helps in case of fire too). Some interior walls are drywall, others are plywood.

On some new interior and exterior walls we just had installed, they were set on over sized horizontal rebar-filled footings with vertical rebar attached to the horizontal. Cinder blocks were set over the vertical rebar and the blocks were filled with concrete to the top of the wall. The walls were painted with a bonding substance called "Perma-crete" (I think) and then the walls were covered with a 1/2 inch thick 2 (or 3) part sand to 1 part cement mixture, which is a 2 step process with first a scratch coat applied and the finish coat applied several hours later. The finished product ends up as an even medium sanded finish. This appears to be a fairly standard finishing technique here and is not really a true plaster or stucco finish.

Thanks for the info. I'll be down there in just over 3 weeks for my 2 week pmv. Looking forward to the trip. Of coarse I have a million other questions.
