Cleaning Powder Coated Facades

Powder coated finishes on aluminium profiles are extremely durable which is the reason why powder coating to the QUALICOAT standard is rapidly on the increase. Finish life expectancy can be maintained and even prolonged with regular routine and simple maintenance.

Importantly, the completed project needs to be cleaned down professionally prior to handover using the correct procedure to ensure that the finish is not damaged. It is crucial to have areas of impact or abrasion damage repaired should it be present. During cleaning, the protective tape must be removed from the inside and outside of all powder coated surfaces. External tape should not be left on the powder coating in excess of six months in any circumstances as the tape can often degrade in UV light and become firmly attached to the powder coating.

Once handed over to the client, in normal use such as in cities, the powder coat finish should simply be washed down at yearly intervals with clean water or with a ph neutral mild detergent solution in water. This should be enough to protect the visible surface of the powder coat for many years and can simply be done during the cleaning of windows. The powder coat finish wash down is especially important where squeegee bars are used to clean the glass, as their use tends to place the residue of the cleaning contaminants directly on the powder coated frame which can begin to etch into the surface finish of the coating.

On new and refurbished buildings powder coated finishes will always come with a cleaning and maintenance regime from the company who coated the aluminium profiles. These will be minimal cleaning requirements and need to be adhered to as well as recorded when cleaning takes place. This will ensure the coated finish is maintained within the warranty wording and will help should there be any claim in the future. Warranties vary in time and are dependent of the powder coat finish used and the location of the installation. For example, where the coating is close to the sea, a marine grade or QUALICOAT ‘Seaside’ specification for the coating must be used and the cleaning regime reduced to three monthly intervals as the atmosphere is more corrosive.

Crucial to any maintenance regime is preventative maintenance and powder coating is no exception. If the coating in use has become damaged exposing the aluminium, it should be repaired as soon as possible in order to seal the surface again. If left, corrosion could begin which will affect the area. For repair, either contact the original coater, or any QUALICOAT approved application can offer guidance.

QUALICOAT UK & Ireland offer a basic guide which can be downloaded from their website. This can be referred to as where the original maintenance information has been mislaid and not available to refer to.

The next QUALICOAT UK & Ireland members meeting takes place in Norwich in November, please contact the General Secretary, Jan Lukaszewski, via the QUALICOAT UK & Ireland website, should you wish to attend. For details on the availability of various colours and finishes contact any QUALICOAT UK & Ireland member for more information.

Qualicoat (UK & Ireland)

QUALICOAT is a quality label organisation committed to maintaining and promoting the quality of lacquering, painting and coating on aluminium and its alloys for architectural applications. To determine whether or not a coating meets a customer’s requirements, the results need to be measurable against technical specifications. On behalf of customers who have products coated, QUALICOAT defines comprehensive quality requirements and monitors their compliance by licensed plants worldwide. As a result, purchasers of coated aluminium receive a premium-grade product delivering long-term value with good quality. Since inception QUALICOAT has consequently made a great contribution to assuring the quality of aluminium parts used in architecture. History of the Organisation

In 1986 several national associations encompassing coaters of architectural parts formed the QUALICOAT organisation. Their goal was to raise and standardise the quality level throughout Europe, laying down rules applying to their industry. Firms in many European countries have directly or indirectly become members of QUALICOAT. The aluminium industry was represented by delegates on the committees from the outset. This ensured information sharing among wrought aluminium producers and coaters. Today membership extends beyond Europe with associations in Australia and South Africa and producers of coating materials in Asia, America and Europe. Membership is open to all national associations of coaters, EAA and producers of paints, powders, dyes and chemical products.
