Yes, depending on the condition of boards, e.g., shellac, glue, or varnish on the floor we will start with a 24 grit belt and go progressively through finer grades, finishing your floor with 120 grit paper.

Floor sanding equipment is heavy duty, industrial machinery.
If the machines are not used properly and kept constantly moving, evenly across the floor, the resulting unsightly sanding marks will damage and lower the value the floor. Should you have any doubts over sanding your own floors, you should consider employing a professional to carry out the work. Dust is the main problem encountered in floor sanding and then, only when old or poorly maintained equipment is used to do the sanding. Boston Floor Sanders use modern machinery utilising the best German and Swedish technology which conforms to the high standards for dust control demanded by European countries. Any floor sanding professional who says he can eliminate any dust problems is probably exaggerating as its all around us.
