Heh heh, I've painted a total of 2 (two) stucco exteriors since moving north...Both repaints, both involving primers, one with Gripper, one with Loxon. One house was over a hundred years old, the other on the national register of historic buildings, built in 1929.
My new stucco experience has all been in the north-east Phoenix area, Paradise Valley, Scottsdale and Fountain Hills.
I have posted here a few times how water-curing is the only true safeguard against a stucco finish burning. If the lime is not leached out and the stucco cured to a near concrete hardness, when the stucco cracks (the ONLY guarantee a stucco guy makes; It will crack) the residual lime (Alkali to the book-learned
) will slowly leach through those cracks and prematurely discolor the finish...
The only safeguard against the cracking that I know of is around 30 mils of elastomeric...
Oh BTW, welcome to our small-yet-tenacious waterhole...
