Why You Should Always Wash Your House Before Painting or Staining in Spokane
If you're planning a DIY weekend painting project or hiring professionals to give your Spokane home a fresh coat of exterior paint or stain, you're making a great investment in your property's curb appeal and protection.
Before a single drop of primer or paint touches your siding, fence, or deck, there is one crucial step you cannot skip: a thorough professional wash.
Why Paint Fails on a Dirty Surface
Paint doesn't stick to dirt—it sticks to the surface underneath it. If you paint over a wall that hasn't been properly washed, you're setting yourself up for failure:
Hidden Dirt and Dust: Fine layers of road dust, pollution, and pollen settle into the microscopic pores of your siding. If you paint right over them, the paint bonds to the dust layer instead of the actual material. Within a year or two, it starts cracking, bubbling, and peeling off in sheets.
Chalky Oxidation: Over time, old paint breaks down into a powdery, chalky residue. If you paint over that chalk without washing it away, the new coat has nothing solid to grip.
Trapped Mold and Mildew: If there is microscopic mold or mildew spores on your siding when you paint, they will keep growing underneath your new paint film. As they multiply, they push the paint outward, causing blisters, rot, and premature failure.
The Right Way to Prep Your Exterior
Washing a home before painting isn't just about rinsing away surface grime; it's about properly conditioning the substrate:
Soft-Washing: Safely eliminates all organic growth, mold, and mildew down to the root so they can't resurface later.
Removing Chalking and Residue: Strips away oxidized paint dust and general environmental buildup.
Proper Drying Time: Allowing the surface to dry completely before any paint or stain is applied, ensuring a permanent, rock-solid bond.
Protect Your Investment
If you're going to spend the time and money painting your home, make sure the prep work is done right so the finish lasts for the next decade.
