Touch up paint

What is touch-up paint

Upon request, and dependent on job size, applicators may supply a limited amount of touch-up paint with a completed project. Touch-up paint is supplied in small aerosol cans or bottles with a built in brush for easy application. It is intended to cover small blemishes or to touchup exposed cut ends on fabricated parts.

The touch-up paint provided by Linetec is the same paint used on your project with a cure additive made available by the paint manufacturers. Each paint type has its own additive that changes the paint from an oven-cured product to a non-oven cured one. Touch-up paint does not have the same adhesion or durability as the factory applied coatings, and will exhibit chalking and fading characteristics at a noticeably faster rate than that of your building painted with a baked-on Kynar® PVDF resin-based fluoropolymer finish. Therefore, it is recommended that touch-up paint be used as sparingly as possible, no more than a few square inches, as any touch-up will become faded in contrast with the original building color after only a few years.

What is Kynar 500® PVDF Resin-Based Air-Dry Systems (ADS)

These high-performance ADS (Air-dry System) coatings are designed for repairing, restoring, and/or repainting the metal on buildings that have a factory applied Kynar 500 PVDF resin-based coating. Kynar ADS can also be used for painting materials that will not tolerate the elevated bake temperatures required by spray Kynar coatings. Kynar ADS coatings can only be applied by a licensed fluoropolymer applicator, such as Linetec and its field service and restoration team.

Air-Dry PVDF coatings are based on a fluoropolymer-acrylic resin system, intended for use as a two-coat system. Kynar 500® PVDF resin-based ADS coatings provide very good fade, chalk, UV degradation, and chemical resistance characteristics.


When applying touch-up use extreme caution as excessive use may void the original finisher’s warranty. Because of the serious liabilities involved with field touch-up, Linetec prefers not to manufacture or sell touch-up products but will sell larger quantities (quarts) only under a no liability clause with an authorized signature.

Any job requiring Linetec field repair using ADS because of an unlikely Linetec finish issue is warranted in parallel with the Linetec factory warranty. Field repair projects utilizing the Kynar® ADS system are warranted on an individual basis; the standard warranty for field finishing is 5 years from date of completion. Other warranty options are used depending upon the base metal condition, site location, type of damage, etc.

Linetec's Field Repair Service

Almost any field situation can be repaired by Linetec's field-service. Freight damage, graffiti removal, anodize refinishing, ding and dent repair, metallic field finishing, interior or exterior repair, etc... would all qualify as potential field repair projects.

For more than 40 years Kynar® 500 PVDF resin-based finishes have held the position as the world’s premiere exterior metal finish. Kynar 500® PVDF resin-based Air-Dry Systems offer the same superior weathering properties as Kynar® PVDF, and can be field applied on almost any building material, restoring surfaces to last and look like new.

The tough properties of this ADS coating resist marring and abrasion, withstand airborne pollution without staining or discoloring, and retain their excellent appearance over time. The coatings require little maintenance and can be easily cleaned with mild detergents.

For any repair other than a small scratch or blemish, 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 all be properly executed for a long lasting finish. A minor mistake in any segment of repair will cause major problems over time.

Linetec offers field service and restoration capabilities which can bring your commercial and residential buildings back to their original splendor. Whether your buildings finish has faded and discolored, or your new building has been damaged during construction, we can correct it.

Storefronts and other high traffic areas need to be repainted periodically. As good as it is, painted aluminum is not completely maintenance free, nor does it last forever. Painted aluminum can chip and scratch on high wear areas such as sliding doors and entrance ways.

Linetec’s fully-staffed field service team utilizes Kynar 500® PVDF resin-based air-dry coatings that meet the highest performance standards to refinish the building’s exterior or interior, including such metal structures as: windows and doors, architectural panels and accents, fencing, site furnishings, curtain walls, cladding, storefronts roofing and fascias, skylights, canopies, railings and a wide variety of other metal structures.

Linetec specializes in the repair of construction damage, including bondo repair for dents and miss drilled holes, as well as refinish of premature chalk and fade. The field service team will do repairs or repaint day or night, around the buildings schedule.

As the country’s leading and largest factory applicator of architectural spray finishes, Linetec is unique in our ability to offer restoration services of unparalleled quality. Our professionals possess the knowledge and skill to confidently guarantee the projects compliance to the AAMA High Performance Organic Coatings Specification.

Touch Up of Anodize Finish

Anodize touch-up should not be needed in most cases because anodizing is so hard that it is not easily scratched.

Touch-up should be used even more sparingly over anodize than over paint. Only the visible raw aluminum in the scratch or gouge should be touched up with matching paint (Alodine pretreatment should be applied first). In most cases, the match will not be ideal as anodizing is a transparent to translucent coating while paint typically is opaque and will not blend in.

Other fixes include:
Replacing the damaged piece with a new one
Cladding the damaged piece with another anodized piece
Clean, pretreat and paint the entire assembly.

None of these “other fixes” are good ones. The best repair is not to allow the material to get damaged in the first place. The number one cause of damage on the jobsite is not protecting the anodized material from harsh chemicals such as concrete/mortar or muriatic acid/brick wash. If reasonable care is taken during handling and high and low pH chemicals can be avoided, repair and/or touch-up of an anodize finish will not be needed.
