Posted and picked up a house with a 21' x 21' x 10.5' unfinished garage. Will park in there in the winter and normally wash vehicles in it with doors open if its really sunny out (for the shade). I will insulate it and am looking for ideas on garage wall/ceiling finish ideas. I have done a few in drywall and have considered other materials than the usual gyprock.
If i go drywall again i will try this new ultra light stuff and paint it with a gloss to repell water the best. Comments?
