Bathtub refinishing also known as bath resurfacing , bathtub reglazing or bathtub re-trimming is the refreshing process of the bath surface which is outdated and damaged for such new condition. This process usually involves the repair of damaged areas. Chips or cracks are fixed using Bondo or other types of polyester putty. After the repair is made, the surface is prepared with acid etching. Etsa provides mechanical adhesion. Porcelain, enamel, and fiberglass tubs are not porous and do not provide a good substrate for new layers to be installed. Etsa surface provides a porous surface that will allow proper adhesion. Another possible method is to apply a adhesion-promoting bonding agent such as silane to the surface before applying layers. Both of these methods can be used simultaneously or independently. The greatest adhesion is achieved by using both methods together. Some new refinishing processes do not require the use of etching, by relying on silan only. After preparing the surface, the primer is applied, followed by the top layer. Generally, a two-component synthetic white coating of catalyzed catalysts is applied, but this coating lacks the abrasive resistance or resistance of the original enamel glass layer of the factory new bathtub.
The coating used to create a new bath layer may be epoxy, urethanes, hybrid polyesters, or polymers. These coatings can be rolled, brushed, or sprayed.
Bathtub refinishing is possible using DIY kits from hardware stores, but some may choose professional service companies offering refinishing services. DIY kits do not generally offer the same level of bonding and thus, deteriorate more rapidly, relying primarily on epoxy adhesion. Without professional spray equipment, a final aesthetic look may show brushes or roller marks.

Dangers
Findings from the Fatality Assessment and Evaluation Control (FACE) program have identified at least 14 worker deaths since 2000 associated with the use of methylene chloride for bathtub refinishing. Products containing a high percentage of methylene chloride are used as stripping agents in the process, to remove the old coating on the bath. In an unventilated setting, excessive exposure to methylene chloride vapors may affect brain function and result in short-term mortality, with possible long-term carcinogenic effects.
Measures to prevent excessive exposure to methylene chloride include the use of stripping agents that rely on other chemicals instead, the proper exhaust ventilation exists, and the provision of appropriate personal protective equipment (eg, Respirators). Using tools handled for a long time can also reduce the proximity of workers of the product, with beneficial effects.
