I'm using the leftovers from The Artist's Studio flooring, various lengths of board Mike cut for me. It's good to use pieces from my stash and it was just the look I wanted. In this instance, I glued the individual boards directly to the mdf floor base using Elmer's wood glue, supplemented as needed with dots of super glue gel.
I sanded the boards with my Dremel Multi-Max oscillating tool, first using 60 grit paper followed by 120 grit paper. The end result was a smoother surface, but I left it a little uneven to keep the rustic beauty. I stained the floor with Minwax Dark Walnut. Since these were different types of wood, the stain didn't mask the random coloration I liked so well. It just darkened the look overall. Dee-gorgeous! I had originally planned to sand this and apply another color as accent but I couldn't touch this finish.
This is not meant to be a high polished floor, so I will leave it as is since this stain also seals. I added nail detailing using an awl and paint. A subtle addition.
