So far, here’s the plan for “finishing” the walls. Subject to change as I see new and different cool stuff to buy.
Exterior walls will be DryLok-ed, then Insulpink with 1×3 furring strips held by Tapcon screws right into the block.
Sheathed with 7/16×4 x 8 OSB (at HD it’s only $1 more per sheet over sheetrock, and this will hold a screw anywhere, no hunting for studs).
Inner walls will be OSB over 1×3 (no insul)
One framed wall will be OSB over 2×4 studwall.
OSB may get painted or just sealed. I’ll see how it looks once it’s up.
