This is a product we spray on the bathtub as soon as it is installed in the home, this is usually done in the framing stage. The home is still exposed to the elements, and subject to damage accidentally by the plumbers, electricians, insulators, drywallers and others. This product is a thick rubbery substance that protects the bathtub until the home is completed. It peels off easily during the cleaning stage. This can also be used an additional service a painting contractor can offer to differentiate themselves.
