Answer for Does exterior stucco paint breathe?

Acrylic coatings (paints) designed for stucco surfaces do allow excessive moisture to leave the wall while protecting the stucco from moisture intrusion. The amount of "breathing" is a bit different for each type of coating and also different from manufacture to manufacture.

I suggest you find out what's available in your area by visiting your local paint stores. Ask for the spec sheet (technical data sheet) on the products they offer and compare each different coating. Look for the part that says "Vapor Permeability".
