What Makes a Good Pressure Washing Job?

blog-pressurewashPressure washing has turned into the de facto method for cleaning a home’s or commercial building’s exterior. On a very general level, the system emits a fast, concentrated stream of water, which then takes off mildew, dirt, mold, and other accumulated substances. Yet, for it to be effective, kinetic energy comes into play, and this helps loosen the particles before the stream washes them away.

While pressure washing is strong enough to remove even graffiti from a surface, a job is typically more effective through the following points:

You Have the Right Equipment

Whether you or a professional does the job, what’s used makes or breaks it. Too strong a system might result in damage. What’s a good match?

  • 1300 to 1900 PSI: This low-pressure system is best for residential jobs, including for homes, cars, grills, fences, patios, decks, and outdoor furniture.
  • 2000 to 3100 PSI: Go up a notch for larger, stronger decks, patios, siding, fences, and boats.
  • 3200 to 4200 PSI: Try this strength when you want to strip off paint or do surface preparation.

Along this line, check the nozzle. Low, broad pressure is best for cleaning, and narrow for cutting into the surface.

How You Clean

Don’t just spray. Instead, it’s recommended that, when you’re doing a vertical surface, you start from the bottom and go up. Then, rinse it from the top down.

And, before you attempt any large-scale job, it’s best to test a small, less conspicuous portion.

Angle is further an important factor. To avoid scratching or denting a wall, hold the nozzle at an angle above. As you spray, always keep it moving; otherwise, you’ll end up cutting into the material.

Watch Where You Spray

Sometimes, a pressure washer is just too powerful for the job.
As a result, it’s a good idea to be careful of:

  • Spraying under or behind vehicle surfaces
  • Light fixtures
  • Air conditioning equipment
  • Windows
  • Frames
  • Overhangs
  • Enclosures

Of course, when you want pressure washing, it’s best to have a professional assess the property to determine what needs to be done.
