PAINTING POLYSTYRENE #49 “PLASTIC” SHUTTERS

The shutters are intended for exterior use. A special grade PG49 panel is made of polystyrene and is available for clients who want to match, for example, their home trim.

• The panels supplied in a variety of colors are made from solid-color polypropylene and are not intended to be painted to change color.

1. Do not expose shutters to direct sunlight before, during or immediately after painting. Control their temperature. Shutters should be between 60 and 90 degrees for best results.
2. Clean shutters using either a mixture of ammonia and water at 1 cup per gallon; or Tri-Sodium Phosphate TSP and water following directions on the TSP container. Be sure to clean all surfaces and into the “nooks and crannies”. Rinse very well and allow to thoroughly dry.
3. Prime cleaned shutter with a good primer. The manufacturer recommends Zinnser Bullseye 1-2-3 or Zinnser Cover-Stain or Masterchem KILZ II or Masterchem KILZ Total One. Follow the primer can’s instructions. A thin coat is better than a thick coat. Two thin coats are better than a thick coat.
4. For best results use a high quality oil base OR latex paint for a top coat. Do NOT use any type of paints that are vinyl based.
5. Apply two coats of the finish, by careful brushing or spray, following the can’s recommendations, especially for the amount of time between coats. A thin coat is better than a thick coat. Two thin coats are better than a thick coat. Be sure to paint the heads of any screws supplied with panels.
6. Allow the shutter’s finish to dry four days prior to installation, especially if the shutter will be exposed to direct sun and high temperatures. This will allow the paint to fully cure.
7. Any screws supplied with the panels are made of aluminum. Pre drill into tough surfaces like wood and do not over-twist the screws. The alternative is for client to obtain desk-type screws and to paint their heads.
