Let there be white!
Finish coat of paint and some enamel on the floor. I used Benjamin Moore Aura in Semi-gloss on the walls and BM Porch & Floor epoxy reinforced enamel on the concrete. Flowed like butter.
The original flooring in this area was linoleum from the previous owner. I've never been so sore in my life scraping that glue up. I eventually had to get in the corners with an angle grinder to get the last of it.
Did an acid etch to prep the concrete and painted.
