As you scrape, you may find that the wood has turned gray or black in some areas. Check for rot by probing these areas with a nail. Spots that are discolored but firm are simply weathered. Weathered wood doesn’t hold paint very well, so sand away the gray surface. If you find soft areas, you’ve got rot. Small, shallow soft spots can be dug out and repaired with a two-part filler such as Minwax High Performance Wood Filler. But when rot is deep and widespread, it’s best to replace the entire piece of wood.
This job is usually done by a professional house painter. The painter will assess the walls, clean, and make any necessary repairs or removal of old wall coverings. They will also tape off any adjacent surfaces and cover nearby furniture and floors with drop cloths. Typically, they will apply a layer of primer, then one to three coats of paint, depending on the color and coverage. Once the paint is dry, they take a final walkthrough to inspect and make any necessary touch ups. House Painting Westminster Colorado
