Maintenance – Powder Coated Metals

Ongoing Maintenance for Powder Coatings

Maintenance for Powdercoated Joinery, Anodised Metals and Painted Surfaces.

How long before maintenance for Powdercoated joinery and Anodised, Painted metals is required?

Maintenance for Powdercoated joinery and other coated surfaces (a recoat) is usually between 3 to 5 years for sunny aspects, and 7+ years for more sheltered areas. For angled window sills and door/slider sills subject to foot traffic usually between 2 and 4 years.

As with all paints and coatings the time between subsequent recoats is dependent on the quality of the metal and initial powder coating/paint, good surface preparation, coating application, number and thickness of initial coats, the environment (coastal and sunny aspects) and whether the surface has been kept clean with frequent washing particularly in coastal zones and near busy traffic thoroughfares.

How long does Everbrite Protective Coating last on powdercoated joinery, anodised metals and painted surfaces?

When applied correctly the coating does not need to be removed. A maintenance recoat anneals to (blends/melts into) the previous coat and ‘becomes one’ again, giving more years of protection. Everbrite is a maintainable DIY polymer coating. Other clear coatings that have to be sprayed on are usually cross-linked coatings which need to be removed by sanding, grinding or burning off before any maintenance re-coats can be applied. Everbrite does not require such intrusive surface preparation – simply clean off the grime with soapy water, rinse well,  allow to completely dry and then recoat.

How easy is the Maintenance for powdercoated joinery and other coated surfaces?

The coating can be maintained indefinitely without any need for specialist intervention. A pre-coated surface only needs to be thoroughly cleaned using a mild soap and water and then rinsed well with clean water to remove dirt and grime. No sanding or other preparation is required. Because Everbrite is self annealing this means that new maintenance coats can be applied directly to the pre-coated surface.

How can you tell when a recoat is needed?

It is best to recoat at the first sight of ‘bleaching’.  Once recoated the bleaching disappears. As long as the original coating is still intact just clean and dry the surface and apply another coat over the previous coat(s). Because it anneals to itself and becomes one, maintenance is easy providing more years of protection. If there is premature ‘bleaching’ this will be because there were not enough coats applied initially for the conditions. e.g. angled window sill areas facing all day sun and roof skylights. It is important to apply adequate coats on surfaces subject to all day sun.  See next two photos

Premature Bleaching

Premature bleaching after 2 years is caused by only one coat having been initially applied. This roof skylight (and for lower sill areas of windows and doors that are exposed to all day sun) require two to three generous coats for lasting protection.

Bleaching is easily rectified

Premature bleaching is rectified with a simple recoat(s) straight over the top of the cleaned pre-coated joinery. At the first sight of bleaching a maintenance coat can be applied without any build up of the coating as it anneals to itself and becomes one.
