Coil Coating Frequently Asked Questions
Welcome to Valspar coil coatings general questions and answers section.
Color Selection
- What colors are available?
Just about any color you can imagine. We have formulated more than 60,000 different colors. Many colors are available in energy star, LEED, and title 24 formulations.
- How can I request a specific color sample on a metal substrate?
Please contact our coil customer service department at kbright@valspar.com or call us toll free at 1-888-306-2645.
- How can I find the RGB values of standard Valspar colors?
Find a reputable graphics or graphics design provider that has a color correct computer system. They can provide true RGB values.
Please note that colors appear differently on different electronic devices such as copiers, printers, scanners, Etc. - How do I request literature?

Buy or Specify Valspar Coatings
- Can I buy coil paint products directly from Valspar?
Valspar sells coil and extrusion coatings to approved applicators. Our approved applicators have the expertise and the equipment to properly apply the coatings.
For a listing of protective coil coating applicators, please contact a Valspar Representative at kbright@valspar.com or call us toll free at 1-888-306-2645. - How do I specify a Valspar product?
To specify a Valspar product, refer to the "To Specify" section at the bottom of the product information sheet. You can find the product information sheets on the coil products page.

Cleaning and Maintenance
- How do I clean and maintain Valspar's fluoropolymer coated surfaces?
The molecules on the surface of Valspar's fluoropolymer coating systems are so tightly bound together that they don't want to react with anything. Their slick surface helps make them resistant to many elements found in the environment such as air pollution, acid rain, and general airborne dirt.
Although Valspar factory-applied finishes are extremely durable, a periodic cleaning to remove build-ups of resins and other residue is a good idea to extend coating life. A variety of methods for removal of surface deposits are available. Simple washing with plain water using hoses or pressure spray equipment is usually adequate. When heavy deposits of dirt or other contaminants dull surfaces, stronger methods may be needed.

Cleaning and Maintenance Guide for Fluoropolymer Coatings
- How do I clean and maintain Valspar's silicone polyester coated surfaces?
WeatherX® silicone polyester coatings are resistant to many elements found in the environment such as air pollution, acid rain, and general airborne dirt. However, if the need to clean or remove deposits from your coating does arise, a variety of methods for removal of surface deposits are available. Two precautions: (1) do not use wire, brushes, abrasives, or similar cleaning tools which will mechanically abrade the coatings surface, and (2) certain cleaning agents listed below should be tested in an inconspicuous area before use on a large scale.

Technical Information
- Why do we often see lines in color match panels and not on the coated building panel?
The small parallel lines seen on lab prepared panels are the result of the application method used in the laboratory. To achieve a uniform thickness of coating in the laboratory, wire wrapped around metal rods is used to apply the coating. The amount of coating applied is controlled by the diameter of the wire used. The wire wound rods apply a wavy film that results in small parallel lines when the coating is drawn down the panel.

Appearance of Lines on Lab Prepared Samples
- Do you have a recommended procedure for recoating coil?
Valspar does not encourage re-coating; however, we realize that it is sometimes necessary. If re-coating is required, Valspar recommends the following procedure:
- Strip should be run through the up to temperature cleaning section.
- Apply tie-coat KXC0073 at a DFT of 0.1 to 0.15 mils; PMT should be between 450°F and 465°F.
- Apply a full film thickness of Fluropon® or WeatherX® coating to the top of the coil at the recommended DFT on the Technical Data Sheet (TDS). Be certain to use Fluropon® over Fluropon and WeatherX over WeatherX coatings.
- Check all physical tests required by the Product Data Sheet (PDS) along with crosshatch impact on line.
- Valspar also recommends that along with the on line physical testing that a crosshatch boiling water test be performed. Reverse impacted/crosshatch panel should be placed in boiling water for a minimum of fifteen (15) minutes, then test to check for intercoat adhesion.
It is Valspar's position to not be responsible for field claims resulting from re-coated coils.

Procedure for Re-Coating Coils
- What are mica and metallic paint systems and how are they best used?
Valspar offers several finishes with a metallic or pearlescent appearance in our extrusion and coil coating product lines. Fluropon Classic® and Fluropon Classic® II are available in both spray and coil formulations. Acrodize® coatings are available only in spray formulations.
When a sparkle effect is desired, we recommend using the newer, mica flake formulation technology due its many advantages. Although similar in appearance, pearlescent coatings are formulated with mica flakes while metallic coatings are formulated with metal flakes.
Mica flakes offer better color consistency and it is easier to work with them. They minimize "tiger striping" and the "flop-of-flake" effect in spray application. This phenomenon can make the color appear different from panel to panel. The mica flakes found in Fluropon Classic II will not pick up an electrostatic charge or follow the back and forth movements of electrostatic application equipment like metal flakes will.
