After removing carpet in our living room and main hallway (and later the linoleum from the laundry room), we painted our concrete foundation to look like wood planks. The process is fairly easy, but it can be hard on your knees and back.
We have two large dogs and two small children, so our almost white carpet was constantly nasty. My husband and I both wanted wood floors, but we were already knee-deep in other house projects, so we needed something inexpensive and fast! So, like everything else ugly in my house that needs a quick makeover, paint!
