Bathtub refinishing also known as bathtub resurfacing, bathtub reglazing or bathtub re-enameling is the process of refreshing the surface of a worn, damaged bathtub to a like-new condition. This process typically involves repairing any damaged areas. Chips or cracks are repaired using Bondo or another type of polyester putty. After repairs are made the surface is prepped with an acid etching, some new refinishing processes do not require the use of etching. After preparing the surface primer is applied, followed by a top coat. Generally, a synthetic white coating is applied, but the coating does not have the durability or abrasive tolerance of the original glass-enamel coating of a factory-new bathtub.
Basically bathtub reglazing, bathtub refinishing, bathtub restoration all refer to the process of restoring worn, impossible to clean, chipped or dated color bathtubs to look and feel like new. A bathtub can not practically be “reglazed” as this is a process that requires the heating of clay, one of the main ingredients of porcelain, in a kiln at temperatures as high as 2,500°F.
The end result of bathtub reglazing is bathtub surface that looks wet, has high light refraction and has a deep gloss.
