How to Paint a Composite Door Frame

Step 1: Surface Preparation

  1. Lay jamb horizontally on saw horses or a table.

  2. Remove all the hardware and mask off anything you don't want painted, such as the glass insert.

  3. Lightly scuff sand the surface with a Scotch Brite pad or fine sandpaper.

  4. Wipe the jamb with mineral spirits t to clean any dust or residue from the surface.

  5. Allow the surface to dry completely before applying paint. Do not use hydro-carbon based solvents to clean the surface, as such products may leave a residue.

Step 2: Painting

  1. Apply exterior grade paint with 4" brush, beginning with the panels.

  2. It is common practice to paint both stiles the same color as the exterior side of the jamb. If applying a second coat, follow the manufacturer's instructions for drying time between coats.


  1. When using stains, mineral spirits, paints, or other hazardous materials, always read and follow the manufacturer's instructions. Plastpro, Inc. makes no representations as to the proper use of other manufacturers' products.

  2. When working with paints or solvents, make sure the working area is well ventilated.

  3. Keep away from heat and flame, as materials may be combustible.

  4. Paints or solvents may cause skin and eye irritation. Avoid contact with skin and eyes.

  5. Keep out of reach of children.

Normal Maintenance

Even a well-finished PF Frame will be affected by exposure and weathering from the sun, moisture, and air pollutants. It is considered normal maintenance to re-apply the topcoat approximately every two years.

Due to the variability in finishing materials, application conditions, and techniques, all of which are beyond the control of Plastpro. Plastpro cannot be responsible for the performance of field applied finishes or individual application techniques.
