I used to scrub my stucco with a pressure washer every spring until my neighbor who flips houses stopped me

I was out there last May blasting the south wall of my place near Wyoming and got told I was probably driving water behind the paper and causing rot. He showed me his own house where the stucco was bubbling up from years of that same mistake. Anybody here use a chemical wash instead or just stick to a garden hose with a soft brush?

People act like stucco is made of paper mache or something. I pressure wash mine every two years and its been fine for over a decade. If you keep the nozzle back and dont blast the same spot for five minutes straight how is that any different than a heavy rain storm? Your neighbor is probably just paranoid from flipping cheap flips where the builder cut every corner possible.

Totally agree, keeping the nozzle back is the whole secret, people act like stucco is made of paper mache.

My dad once pressure washed the cedar siding on his cabin and it looked like a wet sponge for three days. Him and the neighbor got into it over beers after and the neighbor said the same thing about the water getting behind everything. @evan_campbell I get what youre saying about heavy rain but rain doesnt hit at 1500 psi from six inches away. We switched to a pump sprayer with some bleach and soap and just hose rinse it now. Less drama, no wet walls.
