When To Powerwash

aspenpainting

do you guys recomend a powerwash on all your exteriors? if not when do you go for it without?

I have a 13 hp honda that puts out 4000 psi, and I can see the difference it makes on surfaces. In fact, I think every time I use it, that is a lot of dirt coming off that paint would not stick to. So, if the surface is not relatively new, I would use it when I can.

Pretty much a SOP

Yup, every exterior gets washed before painting, its part of the deal.

Aspen, we clean every exterior before painting. Not all surfaces really need 2500 psi to get them clean. For example a home that is in really good condition. We apply a chemical to the entire house then wash. If everything is in good shape we just use the pressure washer as a REALLY POWERFUL garden hose. It just rinses the surface so quickly and efficiently that using just a hose seems silly.

Some folks don't like pressure washers and the damage they can cause, but if its done right theres no better more efficient way to clean.

Agreed
