Haven't posted in a couple of weeks, so I'll do some catching up today. The old 9" square green and white tile was stripped off the floor. It mostly popped right up since the glue was so old and brittle. Underneath was the original fir flooring which was fairly flat. Here I'm putting down 1/4" plywood which I had pre-painted with a grey "porch and floor" paint.
A shot of the extension (formerly breakfast nook).
Here Pyro enjoys the clean new floor. In a sunbeam and next to the heater vent, thank you very much.
