How much should I charge to strip and finish it, including materials and projected labor?
On a floor this size in Arkansas, I have seen prices starting at $.22 a square foot to deep scrub and apply 2-3 coats. This would be a standard G.C. spec.
On the other hand, the same job with small rooms and a high gloss requirement (4-5 coats of finish) often commands up to $.50 square foot. The percent of solids and quality of the finish also affects how many coats are required.
