Field Finishing



Your Lancaster Door is designed for low maintenance with a pre-painted steel base and cellular PVC design overlays. Due to the nature of the vinyl overlays on the steel base, General Doors recommends factory colors only. If you choose to paint your door we recommend:

  • Using a "vinyl-safe" or Heat Reflective Paint

  • Choose a color with an LRV (light reflective value) of 55 or higher

  • Properly clean door using a mild detergent and a soft cloth, then rinse with a garden

         hose prior to painting. Do not use a high-pressure spray.

If a darker color scheme is required, consider using our Cambridge Model door, a composite wood product designed to be painted with no color choice restrictions.

Failure to follow these guidelines can cause the vinyl overlay to distort and/or delaminate, thus voiding the warranty.

General Doors is not responsible for any paint manufacturer's performance claims.
