INTERIOR AND EXTERIOR PAINT FOR STUCCO
Paint for stucco or stucco coat as it is commonly referred to, can be used on either interior or exterior projects.
Prior to painting new masonry or other types of stucco, insure that the substrate has cured and has dried thoroughly.
If not, you could end up with problems such as bubbling, peeling or burning.
Surface preparation is very much the same as for any other painting project and as with other projects be sure to read the product label before beginning the job at hand.
Also, your local paint store rep can be an invaluable resource when it comes to stucco coating surfaces.
Stucco paints are designed for rough substrates requiring a breathable coating. Giving stucco the chance to breath keeps the dried paint surface from cracking and peeling. Once the stucco is painted the coating used must have the ability to hinder the same type of cracking and peeling from recurring in the future.
Stucco paint does tend to bridge well, (cover small cracks and holes) usually better than regular type paint products. The stucco paints excellent bridging properties are due to it being pliable and rubbery. Since the coating is rubbery it will easily expand and contract with the movement of your substrate.
Surfaces that do have cracks or small holes can be repaired using paint-able caulking or fillers suited for stucco type paint products. Do keep in mind though that most larger repairs, no matter how well they are done, will in most cases be difficult to hide.
I have found from experience that priming the substrate before applying your stucco paint will give a better look to the final finished surface. Also, for the best possible job on exterior projects, use an elastomeric product. This

No matter what type of paint for stucco you use, most can be sprayed on or brushed and rolled. Stucco paint is more difficult to work with though, due to its thicker viscosity. Also, rough surfaces which stucco usually is requires a certain amount of spraying or rolling practise. You might want to start your painting project on the least visible area of your home, the back of a garage for example, so as to test your painting skills prior to beginning the main parts of your house.
If you are spraying back rolling is advisable. Back rolling is the process of using a paint roller to roll out your wet paint immediately after it has been sprayed on. Back rolling eliminates sags and runs along with enhancing adhesion, while at the same time pushing the paint into all those hard to get at nooks and crannies.
With that said, if you are going to use a paint sprayer be sure to check with your local tool and equipment rental shop regarding the paint sprayer and sprayer tip size you will need. Not all paint sprayers can spray thicker type stucco paints. Your local rental shop may not be able to supply you with the equipment needed for the intended job at hand.
