Before painting, the painters carry out several preparation tasks such as: Cleaning the Exterior: This typically involves pressure washing to remove dirt, mildew, and loose paint. Repairing Surfaces: Any damaged or rotted wood is repaired or replaced. Priming: A primer may be applied to ensure proper paint adhesion, especially on bare wood or stained areas. Masking and Covering: Windows, doors, and landscaping are protected from paint drips and overspray.
