Staining a Composite Door Frame

Step 1

Wipe down the composite door frame with a cloth dampened with mineral spirits. Allow 15 minutes for the mineral spirits to evaporate.

Step 2

Cover the flooring with masking paper. Tape the paper down to prevent it from blowing up and sticking to the wet stain.

Step 3

Apply blue painter's tape to any areas you want protected from stain. Frame the walls surrounding the composite door frame with blue painter's tape if you are an inexperienced painter and believe you may have problems with brush control.

Step 4

Pour the stain into the 5-gallon bucket. Fill it to about two-thirds capacity.

Step 5

Apply stain to the composite door frame using the 3- to 4-inch oil-based paintbrush. Brush vertically. Do not overapply as stain is thin in density and can easily splatter and drip.

Step 6

Allow the stain to dry for two hours. Apply additional coats for a darker finish.
