One of the most useful time-saving tools to emerge in recent years is a pressure washer. Cleans dirt, grime, and chalking paint from otherwise sound painted surfaces with its high-velocity water spray. Pressure washers are popular among professionals not just because they are quick but also because they scrub the old paint, allowing the fresh coat to adhere better.
A pressure washer is especially good at removing dirt, grime, and chalking, the powdered pigment left on the surface when old oil and latex paints degrade. You won’t need a cleanser (non-phosphate substitute or TSP) since the scouring action is vigorous.
Before pressure washing, check first for chalking by rubbing your hand to the painted surface. After that, you must repair such as replace rotten boards and renailing loose ones so that water doesn’t drive through the wall and siding.
First, practice using the washer in a low area. Hold the wand in both hands and move it from side to side across the siding at a steady pace. Start approximately 2 feet away from the siding and work your way closer until you find the best cleaning distance. In general, work at a slightly downward angle to prevent pushing water up under the siding.
Initiate from the top and work your way down the walls. Wash the gutters, soffits, and siding as well. When possible, keep the spray away from breakable things like windows and exterior lights, and remove house numbers and window boxes.
Pressure washers can help remove loose paint, but they can’t replace scraping. After pressure washing the area, scrape off any remaining loose paint.
Avoid driving water into joints, gaps, or against the glass by directing the nozzle away from windows and holding the wand at an angle. Even so, inspect the inside sill for any water that has spilled. After washing, remove the shutters and clean underneath.
To wash high areas, use an adjustable extension wand. It is safer than pressure washing on a ladder.
With a scrub brush and a combination of TSP and detergent mixed in water, clean the high areas beyond pressure washer extension. So that the TSP won’t leave noticeable drip marks on the siding, keep it damp. When finished, use a garden hose to rinse from the top down.
If you like instant gratification for cleaning and house maintenance, pressure washing might be fulfilling for you. On the other hand, you could decide that pressure washing is too much hassle. And that’s OK! It’s a nasty task, and you’ll almost certainly end up soaked.
Contact a professional specialist for assistance if you’d rather have someone else do the pressure washing. With a bit of elbow grease and water, your house will be clean outside, just like inside.
