Yes, it is highly recommended to wash a house's exterior before painting to ensure the best results. Cleaning the surface removes dirt, dust, grime, mold, mildew, and old paint, which allows the new paint to adhere properly and results in a smoother, long-lasting finish. Failing to clean can lead to poor adhesion, peeling, and an uneven appearance. Pressure washing is an efficient method for this, but be cautious not to use excessive pressure that could damage siding or wood. For materials like vinyl or stucco, soft washing might be a better option. After washing, allow sufficient drying time, such as three to four days, before painting to prevent trapping moisture, which can cause blistering or peeling.

Sodium bicarbonate does not need to be cleaned up as thoroughly as many of its aggregate counterparts because it is not considered dangerous to the environment, nor to pets or people. While you will likely want to clean up the dust with a shop-vac and some water for aesthetic and comfort reasons, soda blasting cleanup is much simpler than for most sandblasting.

Hardscaping is made to withstand the elements, but it still needs regular cleaning as well as maintenance like weeding, replacing broken pieces, removing mold or mildew, and more. Use an appropriate cleaner for the hardscaping material with a stiff brush to remove dirt and other material, or use a pressure washer for a deep clean. Staying on top of maintenance can alert you to any problems with your hardscaping that will need repair or replacement.

You should avoid using a pressure washer on any surface or item that could be damaged by the high-pressure spray, as some materials are too delicate to withstand the force.

Key items and surfaces to avoid include:

• Electrical Components: Never pressure wash electrical systems, as water can cause short-circuits and create a safety hazard. This includes utility meters, breaker boxes, electrical outlets, generators, and HVAC or air conditioner units.

• Delicate and Fragile Materials: Fragile items can crack, shatter, or be stripped by the pressure. Avoid pressure washing windows, glass, light fixtures, shingled roofs (especially asphalt), and stucco.

• Painted, Stained, or Sealed Surfaces: Unless your goal is to strip the finish, do not pressure wash painted surfaces, stained wood (like decks), or anything with a protective seal that could be stripped away. Be especially cautious with older surfaces that may contain lead paint.

• Soft Woods and Certain Decking: Delicate surfaces like softwood, composite decking, and antique or wooden patio furniture can be etched or damaged. If you must wash wood, use a lower-powered pressure washer with a wide-angle nozzle to prevent damage.

• Living Things: Never use a pressure washer on people, pets, or plants. The force can cause serious injury and will destroy landscaping.
