Dryvit (Stucco) buildings...

[Sonlight]

We have some "dryvit" or sometimes called stucco houses in my area. Not many but they are here. There is a guy with a hot water unit that seems to be the real pro on these tricky houses. Anybody know the secret to cleaning these without blasting off the dryvit? Is it just really low pressure?

The key is to use the best cleaner for whatever it is that you are trying to remove. Attached is a before/after picture of Dryvit cleaning BEFORE it was rinsed. It was then rinsed with cold water & 1000 psi.

Excellent job Dan!

Is there a chemical that you recommend?

I was recently asked to give an estimate for a house that is half brick, half dryvit. I've never done that surface before and I'm a little nervous about it. I don't want to use too much pressure. So are you suggesting more chem/less pressure for this? How much pressure on this surface is too much?

Too much pressure depends on the each individual dryvit structure. I've found that the integrity of the different surfaces can vary greatly from job to job. One thing to keep in mind is that the borders around windows, columns and other prutruding areas are much more suseptible to damage then the regular wall surfaces.

I concur that for stucco it is always preferable to focus on good chems and less pressure. Also as a pre-warning for whatever reason i have f ound that stucco homes have a problem with leaking through cracks into the homes through windows/doors that werent sealed properly etc. Its probably just shoddy work on stucco in my area but i just thought i would mention it. So just something to check for as your doing the work. Good luck, stucco homes generally look excellent once your finished as the picture posted above shows.
