Polyester/Epoxy: Is a 2-part compound that is applied with an
airless sprayer. Poly/epoxy is a very common refinishing method used by “Miracle Method” and many others. Poly/epoxy can last anywhere from 5 to 25 years with
proper care. The longevity of the finish is largely determined by surface preparation, temperature and humidity control during application and the skill of the person
applying the finish. Poly/epoxy is considerably softer than porcelain and may be prone to cuts (especially from knives in kitchen sinks), but it is very flexible and
resists impact damage well. When Bathroom Machineries has vitreous china fixtures refinished, we recommend this method.
Is a relatively new process for plumbing fixtures, though it has been around for decades as a protective finish on heavy equipment and machine tools. Powdercoating is the closest thing to porcelain for luster, cut resistance, and durability.
Powdercoating is electrostatically applied at high temperatures to form a bonded coating. The actual life span of powdercoating on plumbing fixtures is yet to be determined as we haven’t managed to wear any powdercoat refinished fixtures out yet! All Bathroom Machineries refinished cast iron fixtures are powdercoated, something yet to be offered by any other company selling refinished antique plumbing fixtures. Fixtures that have been powdercoat refinished are difficult to tell apart from new porcelain glazed fixtures. At present time, powdercoating represents the state of the art in cast fixture refinishing technology.
Vitreous China Fixtures: “Vitreous China” means a fixture is made from solid porcelain (like a coffee mug or
toilet for example.) The glaze on china fixtures is fused onto the surface as part of the firing process in the kiln. Generally speaking, the finish on china fixtures is more
durable than the glaze on cast iron fixtures as the finish is an integral part of the surface. China fixtures also have the advantage of being free of rust problems that can
shorten the life of cast iron fixtures.
Refinishing Vitreous China Fixtures:
Since it is an electrostatic process, powdercoating can only be applied on electrically conductive items. China fixtures are not conductive and must be refinished with poly/epoxy coatings. With its excellent impact resistance, poly/epoxy coatings are perfect for lavatory fixtures. Usually, bathroom sinks are not subject to heavy wear and a blow hard enough to chip the finish would probably break the fixture anyway.
At this time, Bathroom Machineries is is not taking in fixtures from our clients to have them refinished. While powdercoating is an effective method of refinishing cast iron plumbing fixtures,the time lag in getting them back from the powdercoaters is grown to be over a year, and we no longer want to be held responsible when 16 months go by before we receive parts back.
If we are aware of a powdercoater in your area that’s familiar with this process (it’s a bit of a trick, not all can do it) we’ll be happy to let you know.
