Your Paint Job Is Only as Good as What Is Under It
Most people skip right to the fun part. They pick a color, grab a roller, and go. Then the paint starts peeling six months later and they have no idea why.
Here is the honest truth. Surface preparation accounts for nearly 80 percent of a paint job's longevity. That is not a small number. That is basically everything.
Paint will not stick to a dirty, chalky, or moldy surface. Even the highest quality paint fails when the wall underneath is not clean. Pressure washing strips away all of that invisible buildup before you even open a can.
Pressure washing can actually double the lifespan of your paint job, pushing it from three to four years all the way up to seven to ten years. That is a massive return for one afternoon of prep work.
Wait 24 to 48 hours after washing before you paint. Let the surface dry completely. Then go for it.
Do the prep. Do it right. Your future self will thank you.
