Picture Frames

Picture frames may combine wood, MDF, metal, plastic, and existing decorative finishes, so preparation and paint choice depend on the actual frame material.

Painting surfaces

Picture frames commonly use wood, MDF, metal, or plastic, with molded details and existing finishes affecting cleaning, sanding, priming, and adhesion.

Surface	Typical area	Preparation	Main consideration
Wood	Solid frame rails, carved profiles, and decorative molding	Clean thoroughly, repair defects, dull glossy finishes when appropriate, and prime bare or stain-prone areas as needed.	Existing finish, grain, carved detail, and stain bleed
MDF	Flat or molded engineered frame profiles	Avoid excess moisture, seal exposed absorbent areas, and use a compatible primer before topcoating.	Edge absorption, swelling, and keeping molded details crisp
Metal	Aluminum, steel, or other metal frame profiles and trim	Degrease, remove loose corrosion or coating, and use the primer required for the actual metal.	Metal type, corrosion, adhesion, and handling
Plastic	Molded decorative profiles, trim, and lightweight frames	Identify the plastic when possible, clean it carefully, and use only compatible preparation and coating systems.	Plastic type, low surface energy, flexibility, and adhesion

Paint types

Picture-frame finishes range from acrylic and chalk paint to spray and metallic coatings, with material compatibility and detail retention guiding the choice.

Paint type	Typical use	Main consideration
Acrylic paint	Prepared wood, MDF, and compatible decorative surfaces	Use thin coats where molded or carved detail needs to remain sharp.
Chalk paint	Decorative matte finishes on compatible wood and furniture-style frames	Frequently handled frames may need a compatible protective finish.
Spray paint	Compatible metal, plastic, wood, and detailed frame profiles	Match the primer and aerosol formula to the actual material and existing finish.
Metallic paint	Decorative gold, silver, bronze, and other metal-like finishes	Base color, surface smoothness, application method, and clear finish can change the final metallic effect.
