Touch-up paint is made up of two components the first being the actual paint that has been applied to the aluminum. The second is an air-dry additive that has been made available to us by the paint manufacturer. Each paint type has its own additive that changes the paint from an oven-cured product to an air-dry.  This product is to be used in small amounts and is recommended to only be used over minor scratches and blemishes. Touch-up is not to take the place of the factory-applied product as its sole purpose is to cover small scratches and it should not be applied over mill material. The touch-up paint does not have same adhesion, durability, chalking and fading characteristics as the factory applied coating.

Directions for Use of Acrylic Enamel Touch-Up Paint (PDF)

If your building has been painted with a baked-on fluoropolymer finish it will resist color fade and chalking for an exceptionally long period of time. The touch-up paint provided by Linetec is an air-dry acrylic enamel which will exhibit chalking and fading characteristics at a much faster rate than that of your building. Therefore, it is recommended that touch-up paint be used as sparingly as possible, as any touch-up will become faded in contrast with the original building color after a few years.

Regardless of the type of paint used on your original finish, please follow touch-up directions carefully for proper adhesion and final aesthetics in the coming years. This especially applies to the recommendation to use an artist's brush to apply the paint. Spray application is not recommended for touch-up paint. Applying the touch-up with a wide brush or other than a small artist's brush is not recommended.

Should there be  a wide spandrel panel which has been pre-painted with a fluoropolymer finish which may require extensive touch-up, air-dry fluoropolymer systems are available, but need to be applied by a licensed fluoropolymer applicator. Should this be necessary, please contact Linetec for a quote on our field repair services.

On any large-scale or touch-up application, we strongly suggest our Linetec Field Repair Department inspect the situation and determine the best suitable paint or repair procedure. Surface preparation, application, and finish should al be properly executed for a long lasting finish. A minor mistake in any segment of repair will cause major problems over time.

Linetec supplies air-dry finishes to aid our customers in minor situations. Under normal conditions we estimate that six (6) aerosol touch-up cans should be sufficient for every 10,000 square feet of material which was painted at Linetec
