Touch-Up Paint – How to Apply and When to Use

What is Touch-up Paint

Upon request, and dependent on job size, applicators may supply a limited amount of touch-up paint with completed projects. 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 touch-up 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 PVDF (Kynar®) 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® ADS

Field repair to interior sills damaged during installation

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

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

Warranty

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.
