Should You Power Wash Before You Paint? Taking a Closer Look at Some Outdoor Painting Guidelines

If you’re in the midst of assessing the myriad of contemporary home improvement options available in today’s day and age, it’s important to note that nothing can revitalize and beautify your home’s exterior quite as a fresh coat of high-end paint does.

However, it’s worth pointing out that modernized paints can do far more than just recolor and reimagine your home’s façade:

  • Prevent Pest Infestations: Termites and other unsavory critters are very adept at squeezing into the various nooks, cracks, and crevices that tend to arise as your paint ages and degrades. Thus, a professional paint job is the best way to seal and secure your home’s most exposed areas, effectively protecting it from unwanted bugs and creepy-crawlies throughout the year.
  • Added Protection During the Winter: Old Man Winter brings about extreme temperatures, abundant amounts of salt, and expanding ice deposits, all of which can be extremely detrimental to your home’s structural integrity, let alone your outdated paint job. Fortunately, high-end outdoor paint is able to provide an impermeable protective coating that can deflect many of these cold-season drawbacks.
  • Extended Lifespan of Your Siding: Even though vinyl siding can last up to five decades without requiring any laborious maintenance, it’s worth mentioning that a protective paint and sealant can further prolong the natural life cycle of even the most durable siding solutions, which keeps money in your pocket and reinforces your home’s resale value along the way.
  • Superior Protection for Wooden Exteriors: When taking into account the fact that timber-based constructs tend to expand, absorb water, decay, and splinter with the passage of time, it should come as no surprise to find out that professional painters rely heavily on exterior paints to protect wooden surfaces in today’s day and age. A permanent, waterproof seal is the best way to bolster the lifespan of wood without detracting from its natural rustic appeal.

Preparing for Outdoor Painting: Should You Power Wash?

To put it simply, you should avoid pressure washing your home’s exterior if you lack the experience and know-how required to safely execute this type of cleaning but it’s important to understand exactly why:

  • Unintended Damage: Today’s power washers can reach about 1500 PSI of water pressure but it’s important to note that many models can spew upwards of 3300 PSI, which is a harrowing amount of power that can blast through solid wood, asphalt, and even concrete! As such, there’s a good chance that you’ll damage your home’s exterior and cause copious amounts of water to shoot up into your siding, which will soak and waterlog your wall cavities, insulation, wiring, and plaster.
