The second step in how to refinish a bathtub is repairing damage. Your tub may be chipped, pitted, cracked, rusted or even burned. Chips are filled in with special putty, as are pits in the floor. Cracks may be fixed with an inlay. Rust needs to be cleaned out. Burns are sanded down, and then filled in.

Personal Protection

Chemicals are used throughout the process and some of them are quite strong with potential serious health side effects. Personal protection is essential to your well being. Methylene chloride, a chemical frequently used in strippers, can cause serious headaches, dizziness, eye, nose and throat irritation. Exposure to high concentrations in an enclosed area can even be fatal. Please see this paper by the California Department of Public Health (PDF).

Paper or cartridge masks are not sufficient to protect you. A fresh air breathing system is recommended by professionals. A professional exhaust system is also recommended. NAPCO offers a stripper free of methylene chloride; ask your professional refinisher to use it.

The third step in how to reglaze a bathtub is etching. This step achieves a surface that coatings will adhere to. If this isn't done correctly, using top-grade materials, the final coating may very well peel in the near future requiring complete rework. Professional refinishers have the knowledge and skills to get this done right.

The fourth step in how to resurface a tub is priming the surface. Primer can be applied with a brush, but the final result will look like it has been painted on. A trained technician will apply the primer with a professional-grade air brush system. These systems usually run about $750 to $2,000 but are well worth it.

The final step in how to resurface a bathtub is applying a final coating. This can be white, bone or a custom mixed color. The coating is applied with the same airbrush as described above. With training and extensive experience a technician learns to spray evenly, resulting in a drip-free and evenly coated surface. Again, this coating can be applied with a brush or small roller, but the result is almost never satisfactory.
