I just hired a contractor to paint my house. I had purchased Duration
exterior latex in advance. The contractor wasn't familiar with
Duration and thinned it with water, probably by 15-20%. The label,
which he didn't bother to read, clearly says "do not thin". I probably
should have reminded him not to thin it beforehand.
He also thinned the SW A100 primer I supplied, and as a result, he had
to use a lot more of the (thinned) Duration to get a decent coverage.
I'm wondering if the paint has been compromised and if the benefits of
Duration are now gone, compared to a cheaper paint. Would it help to
add some unthinned paint to it to thicken it up? Or perhaps SW sells
some kind of concentrated paint to use as a thickening agent?
Or can this problem be solved by just applying an extra coat? I just
hope I didn't waste a thousand bucks on paint ;)
The good news is that he only did the eaves and one wall so far.
