I have a marble floor job that has several coats of polyurethane on it. I want to remove this coating and restore the stone to its original condition but the floor is located in a hospital and I cannot use any chemical that has a noxious odor.
There are several ways to remove polyurethane coatings without using strong odor chemicals. Space age technology has arrived and there are some new products on the market available for removing these coatings and some have no odor at all. These chemicals are usually sold as safe strippers or non-methylene chloride strippers. Most are available at hardware and home centers. Follow the directions carefully. Unlike methylene chloride strippers the dwell time required to remove the polyurethane is much longer.
