I live in Florida and have a stucco house that need exterior painting. Elastomeric paint was recommended but I am concern of mildew and moisture. I’ve read that the characteristics that make the paint waterproof also give it a low permeability rating. Meaning that moisture from within a structure cannot pass out causing damage in the long term. What is your experience with this paint and what do you recommend?

You do not mention if your stucco is 'raw' (untreated) or, previously painted. If it is still porous enough..you can save money by simply using a top quality Acrylic Latex Paint in a satin finish..you will get good breathability and durability ( up to 10 yrs. or more ). If previously painted or you have numerous hairline cracks…by all means opt for elastomeric paint.. caution: all windows / doors etc. should be properly caulked with a good silicon so moisture does not get behind this coating. This product will not give you more than 150 sq.ft. per gal…but will last for 15 years or more.
