I painted the drywall in the room with a good high quality paint (Behr Slate Grey). I did not bother mudding and taping all the drywall in the basement, since 98% of it will be covered by benchwork and backdrops.
Next up is the purchase and installation of 209 Dricore floor panels, followed by some laminate flooring. The Dricore panels look like this:
The black part is the bottom, and the top part looks like sub floor. This floor material, in addition to some good quality 12mm laminate should provide a comfortable area to work and operate the layout.
I should add I am NOT looking forward to moving 209 panels from the store to my basement!
