I've had so much fun with the pressure washer lately that I thought there was no job too tough for its 1,600 psi stream of water. Then I tried it on the barn siding. The dirt you see at the bottom of the siding is due to six months of rain running off the roof before we put the gutters on. Unfortunately the pressure washer barely budged the dirt. The small clean section just to the left of the window is where I scrubbed by hand with a plastic brush. The brush seemed to do the trick so I circumnavigated the barn with a garden hose in one hand and the scrub brush in the other.
We're removing the dirt now in preparation for painting the siding. What you see now is the primer that is applied to the cement board siding by the manufacturer. The light gray color is kinda pretty in a way, but the siding ought to have some paint on it to help it last longer. If we get a stretch of dry weather sometime this summer we hope to post some painting pictures. Thanks for visiting!
