I am a former owner of a medium sized plumbing company – 3 master plumbers and 5 other staff – and I have years of experience in many areas of home remodeling. I first heard about bathtub reglazing/resurfacing in the late 80’s. But for many years the materials involved were inferior and the acids and solvents used for surface preparation were not only toxic and dangerous but potentially harmful and damaging. Certainly not something I wanted to work with or have my customers subjected to! The materials we use today are far superior to those earlier materials. They produce a high quality product while saving thousands of dollars compared to conventional remodeling costs.
