WHAT IS ELASTOMERIC PAINT
What is elastomeric paint you ask? Well! elastomeric coatings are a latex product and by far the best paint to use on pretty much any of your exterior projects.
Masonry surfaces do especially well with an elastomeric application.
Concrete, stucco, block and brick all show excellent results after receiving a couple of layers of elastomeric paint.
Properly primed wood, metal and vinyls will also readily accept an elastomeric as long as the coating used is compatible with the surface it's being applied to.
Elastomeric paints are much thicker in consistency than other top quality coatings. With that extra thickness comes superior bridging or filling of cracks and small holes.
Elastomeric coatings also work well for those surfaces that have to put up with reoccurring cracks or pin holes. Reoccurring cracks and pinholes are virtually eliminated because of elastomerics inherent ability of expanding and contracting. An elastomeric coating makes it seem as though the painted sub-strait were protected by a rubber balloon.
In the case of climates where severe whether is an issue, (hot, cold, dry, wet or windy) elastomeric is the exterior product of choice. Elastomeric coatings are also extremely durable and when applied properly will last many years beyond it's closest competitor.
That of course was the good about elastomeric paint, what about the bad. Price is a concern for many. Elastomeric coating generally cost more due to it having lower coverage per square foot or meter compared to other products. Professional application may in some cases also require more money due to the paint taking extra time to apply.
Another concern would be that some elastomerics don't breath very well and can with certain colors collect dirt or dust readily, requiring frequent cleaning or washing.
One other disadvantage depending on the job at hand, might be the specialized equipment you could need. I, myself, prefer to spray then back roll elastomeric. I find spraying can, in some cases, make the product look better depending on the surface coated while back rolling helps with adhesion.
Spraying though, would require a good size gun tip (520 or higher) and large paint sprayer, (1 GPM output minimum). Such equipment and tools are not always easily available from your local rental shop and buying a commercial paint sprayer would be cost prohibitive for most non-contractors.
Even so, the average project should result in few problems when brushing and rolling, just as long as one uses a top quality elastomeric product. With that said, and to be sure of a professional job, use the correct primer and follow proper painting techniques and surface preparation advice.
Your local paint dealer is an invaluable resource when it comes to information regarding procedures, products, tools and materials needed when it comes to an elastomeric painting project.
