New products called appliance epoxies are making it pretty simple to update your kitchen without having to spend thousands of dollars. Appliance epoxies are applied just like regular paint and dry with a smooth finish. They can be applied to the exteriors of ovens, refrigerators, dishwashers and vent hoods. They are washable and very durable and come in a range of finishes including black, white and stainless steel.
Clean your metal vent hood thoroughly. Use a de-greasing cleaner to make sure that all grime and residue is completely removed from the surface of the hood. Any remaining oils will interfere with the paint's ability to bond with the surface of the hood and may cause the finish to bubble or peel over time.
Sand the surface of the vent hood using a fine grit sand paper. Sanding will add texture to the surface and will allow the paint to bond to the surface.
Wipe off any sanding dust with damp rags. Be very thorough and remove all dust. Even small particles will show through the paint, causing the finish to look less professional.
Remove knobs and other hardware. Tape off any areas that you don't want to paint including walls and surrounding cabinets.
Roll on the epoxy paint using a good quality brush for the corners and edges. Roll over the paint lines with a smooth foam roller to eliminate seams and brush strokes. Apply the paint to the flat areas with the foam roller using a steady, even stroke. Apply 2 to 3 coats of paint, allowing each coat to dry before applying another.
Wait 24 hours before using your vent hood.
