This is the completed earthen floor. It took many weekends of smoothing and drying the various layers, then soaking the floor with linseed oil and turpentine. After the floor was saturated, I coated it with a solvent-based acrylic sealer. It is very strong now, but softer than concrete and kind to bare feet. I love it. I can mop it and it holds up to lots of foot traffic, but I do have to be careful of heavy furniture on small legs making dents in it.
