Power-washing, painting and repairing scratches are all ways to spruce up exterior trim molding. The best choice depends on the condition of the molding and the desired results. Power washing brings newer molding back to shape, but older molding is likely to require repairs and paint to look fresh again.
Pressure washing removes dirt, grime, spider webs and most stains from trim molding for a fresh look. Pressure washers are available at most tool rental places. A medium pressure works best to clean the surface of molding without causing structural damage. Spraying the trim evenly from the top to bottom provides the best results. A higher pressure removes peeling paint to prepare the trim for repainting. If a paint job is not necessary, applying paint or stain with a small brush covers any scratches or worn spots for a nice, clean finish.
Applying a new color paint to the molding is a good way to give a house a different look quickly without a lot of fuss. Using a neutral tone or a tone that matches the home's exterior makes a house look larger. A bright, contrasting tone lends a cheery, whimsical tone. Adding a contrasting pop of color to the windowsills or through a narrow band on accent molding adds interest and depth to the design.
