Not to bad lost about $500.I guess next time we will keep the house wet also.

Some brands of paints are far more sensitive than others. I've forgotten which one is the worse.... Always beware of fresh paint, especially. Some searching on the forum may reveal the other paint that is prone to discoloration from roof mix. I want to say it's Benjamin Moore, but I'm not 100% certain.

Sorry to hear about the loss either way.

I have to check w/my rep but I believe some acrylic ext paints (like SW duration) take a full 60 days to FULLY cure. Oils shorter even though dry times are longer. Ugly Shingles had this prob with freshly painted white facia boards turning (slightly) lime green. think it went back on its own.

I would say that it was the paint that was effected on it's own and not the surface that it was applied on (Hardy Plank). Hardy Plank and Hardy Panel are cementitious products and I have never had a problem with it.

cementitious

I'm not gonna argue facts with you, but is that a real word? If it is, is it pronounced seementeeus? It looks like someone mated the words cement & letigious and they had an ugly baby.

It is a true word Art !!! LOL

ce·men·ti·tious (smn-tshs)

Of or relating to a chemical precipitate, especially of carbonates, having the characteristics of cement.
[From Latin caementcius, made of uncut stones or rubble, from caementum, uncut stone; see cement.]

**Correction** It's Sherwin Williams, not Benjamin Moore:

Look at the latter posts in the thread.

Art... it is a real word like Kim said. Here's another definition broken down to describe it for the more contractor orientated:

Engineered Cementitious Composite, also called bendable concrete, is an easily molded mortar-based composite reinforced with specially selected short random fibers, usually polymer fibers. Unlike regular concrete, ECC has a strain capacity in the range of 3–7%, compared to 0.1 % for ordinary portland cement. ECC therefore acts more like a ductile metal than a brittle glass, leading to a wide variety of applications.

AND to even break it down more: Concrete that looks like wood. biggrin

(note: sometimes I like to use big words to make me appear smarter than I actually am. Smoke and mirrors Art... smoke and mirrors...) LOL

I apologize for trying to be funny. Kim-you kicked azz on supplying a definition that didn't make me look extra stewpid. Ray-I very much agree on the smoke and mirrors aspect. I just got a kick out of the word cementious, that's all. (It kinda reminded me of the old submarine joke.) Oh, and it sounded similiar to contentious when I sounded it out as they taught me in elementary school. BTW, I think the spell check feature on this forum is brokem.
