What to do with a bare concrete floor????
Well I saw it as a really BIG canvas ... and so transformed it into an old cobble stone look
be sure when painting concrete floors that you start off with a clean surface and add 2 - 3 layers of clear coat when done.. allow plenty of drying time between coats.
It was much easier starting off with a black basecoat instead of painting around each and every stone... beware this, project depending on floor size, can take a long time to complete.
