We wash our hands several times a day and we wipe, vacuum or mop our floors weekly, yet your walls can go without being sanitized for years. Obviously, floors accumulate more dirt and grime, but your walls and ceilings are likely dirtier than you would suspect. A new coat of paint, when applied properly, will cover up permanent marks and stains and give whatever space you are working with a fresh new look.
During a repaint, the first tasks before you or your painter are to sand and clean all of the surfaces. The next step involves laying down a base coat primer. At this juncture, your walls and ceilings are likely cleaner than they have been since their last new paint job. After the new coat of paint is set, it works to seal out moisture; protecting surfaces from being saturated or being eventually contaminated by bacteria such mold or mildew. Paint can also deter dust, dirt, and allergens from gathering on the walls and ceilings. In more dated interiors that have plaster walls, paint can even prevent dust from forming in places where the plaster would have otherwise begun to disintegrate. Once the job is done, you will feel like the interior of your home is the freshest it has been in years.
