QUESTION: For a quicker, cheaper fix, we are considering having our 50-year-old tub resurfaced. Do you have any information about this procedure that we should consider, such as types of materials used or processes involved?ANSWER: Is the tub worth refinishing? A lot of homeowners refinish antique tubs, such as clawfoot models, because they fit better into their restoration plans.But I can't imagine that a tub from the mid-1950s — unless it was one of a kind, custom-made for an unusual space — would be worth the trouble. I'd bring in a couple of refinishers for estimates; first try to determine whether the tub is worth saving, and then gauge for how long a new finish is guaranteed.There are several refinishing methods available, some involving rather unpleasant chemicals. The preparation of the surface to take the new finish is typically the key to any refinishing job.
