Pressure washing your house before painting is a fantastic way to minimize the amount of time spent on preparation and clean-up. However, if you want best results without any risk involved then make sure that stripping should be done separately from pressure washing with tools such as a scraper or sander in this case because they are more gentle than other methods like heat guns which can potentially strip away all paint after just one use!
2 out of 3 painters will tell you that it’s a bad idea. Why? Too much dust.
The other painter will tell you to go for it, and pressure washes the whole house before painting. This is an important question because if you follow the 2 out of 3 painters who say it’s a bad idea, there is probably a valid reason.
“Washing a house with a power washer is usually not a good idea,” says paint contractor Mark Dixon, who has written about the issue on his website. “There are safer and more effective ways to prepare a surface for painting.”
Washing the house with a pressure washer will scratch wood surfaces, roughen smooth surfaces, remove paint in an area larger than the tip of the nozzle, and put tiny pieces of debris into the air which you will have to clean up later. And it gets worse when they are cleaning brick or stone.
Not only that, but pressure washing is very expensive, needs to be done when no one is home because of the noise and is a messy process.
Apparently, it is bad because watermark can’t afford to do professional pressure washing of houses prior to painting. Professional paint contractors can afford to do it, but they only do it when ordered by the customer.
