Step 1
Clean the molding thoroughly with a cleaner like TSP (trisodium phosphate), which doesn't leave a film that could interfere with the adhesion of the paint.
-
Step 2
Let the molding dry.
-
Step 3
Mask off the area around the molding carefully with professional-quality blue 'safety' masking tape, pressing down very firmly on the tape edges you will apply paint to. Try mashing down the edges with a spoon.
-
Step 4
Place drop cloths as needed.
-
Step 5
Have one or more paintbrushes on hand in widths appropriate to the molding you are painting. Purchase a high-quality brush or brushes with the type of bristles appropriate to the product you are using, either oil based or water based.
-
Step 6
Apply a deglossing product (liquid-sanding solvent) according to the directions, which will specify a waiting period before applying primer.
-
Step 7
Apply primer; oil-based primer is best. Note that there's often a window of only 30 to 60 minutes in which primer can be applied successfully over deglosser.
-
Step 8
Sand rough areas after priming.
-
Step 9
Let the molding dry; this may take a day or more.
-
Step 10
Apply oil-based (alkyd) or water-based (latex or acrylic) paint.
-
Step 11
Let the paint dry. Oil-based paint usually takes much longer to dry - a day or more - but many paint experts feel it gives a more durable finish.
-
Step 12
Apply the second coat of paint.
-
Step 13
Let the second coat dry, and remove the masking tape. Oil-based paint should be thoroughly dry before you remove the tape, but some paint experts advise removing tape when water-based paint is still slightly tacky; do what your paint-can directions or paint store advises.
