Polyester Powder Coated Surfaces

 

Most modern steel window frames have a factory applied stoved polyester colour coating. Wash down periodically – at intervals of between three and 12 months, depending on the amount of grime and salt in the atmosphere – using a mild non-alkaline detergent in warm water, applied with a soft cloth or sponge. Using nothing harsher than a bristle brush or nylon pad. Give a final rinse with clear water. The finish will then last between 10 and 20 years before decorative re-coat becomes necessary.

If, after many years of exposure, the polyester-coated surface needs redecoration, a standard undercoat/top coat alkyd system can be used, after the surface has been cleaned and slightly roughened to provide a key.

Small areas of finish that become chipped or scratched can be made good by the application of a touch-in paint available from Cotswold Casements. This will be air drying and cannot be expected to weather in the same way as the original “ovenbaked” coating, so its use should be limited. Large areas of damage are best repaired by specialist contractors, using two-pack resin and hardener spray applied systems.
