Maintenance
Exterior Finish Care
This unit was painted, and heat cured at the factory with a high quality, thermoset polyester
powder coating. The following care will ensure the longest possible life from this finish.
1. If necessary to remove dust, pollen, etc. from housing, wash with water and soap or
dish washing liquid detergent. Do not scrub with a rough cloth, pad, etc.
2. If grease removal is needed, a fast evaporating alcohol or chlorinated solvent can be
used. Note: This may cause some dulling of the paint finish.
3. If the paint has faded or chalked, the use of a commercial grade, nonabrasive
automotive car wax may partially restore the color and gloss.
Field Repair of Texture Paint
1. The sheet metal should be washed and clean of foreign material and then thoroughly
dried.
2. Clean and remove all grease and wax from the area to be painted using Dupont
3900S Cleaner prior to sanding.
3. Use 320 grit sanding paper to repair any scratches or defects necessary.
4. Scuff sand the entire area to be painted with a red Scotch Brite™ pad.
5. Wipe the area clean using Dupont 3900S.
6. Blow and tack the area to be painted.
7. Apply a smooth coat of Dupont 1854S Tuffcoat Primer to all bare metal areas and
allow to dry.
8. Apply 2 medium - wet coats of Dupont 222S Adhesion Promoter over the entire area
to be painted, with a 5-minute flash in between coats.
9. To apply the texture coat, use Dupont 1854S Tuffcoat Primer. The proper technique
to do this is to spray the Tuffcoat Primer using a pressure pot and use about 2 - 5
pounds of air pressure. This will allow the primer to splatter causing the textured look.
NOTE: You must be careful not to put too much primer on at one time, this will affect
the amount of texture that you are trying to achieve. Allow the texture coat to flash for
20 minutes or until dry to touch.
10. Apply any Dupont Topcoat Finish such as Imron™ or Centari™ according to the
label instructions.
NOTE: To re-topcoat the textured surfaces when sheet metal repairs are not necessary,
follow steps 1, 2, 4, 5, 6, 8 and 10.
