Your building’s exterior endures more drama than you probably give it credit for. Blistering sunlight is only the beginning. Add driving rains, hail, and snow and you have to wonder if Mother Nature has it in for bricks and mortar. Thankfully, the coatings industry has been working overtime to produce a range of exterior painting formulations that can withstand nature’s most furious moments. Let’s look at what trendy buildings are wearing this year.
The Resin Revolution
Acrylic resin paints are the royalty of the exterior paint world, beating every other alternative in terms of quality and protection. Every paint includes solvents that evaporate upon application.
Some of the highest quality exterior painting formulations rely on binders made of 100% acrylic resins. They build a powerful film that has just the right flexibility to expand and shrink with icy weather without cracking. Resins are the umbrellas of the coatings world, resisting water and drying in a snap while minimizing often-volatile solvents. They’re strong enough for exterior walls, but if you need turbo power, they can be cured. In their hardened form, they can beat vinyl in the waterproofing game. They are, nonetheless, not perfect.
Even acrylic resin dissolves slightly in moisture, and that can interfere with its adhesion. Pre-treatments can help it to adhere better, but swelling can cause blisters that ultimately make your coating chip. So that velvety exterior painting won’t keep its handsome good looks forever. Water solubility isn’t a problem in sunshine states like Florida where snow and rain are rare, but not all areas are that lucky. Rainy Virginia or snowy Minnesota will need more than mere exterior painting to survive the wet season. Enter polyurethane membrane: an acrylic that resists water in icy-cold weather, keeping your building cozy and dry.
Oil and water don’t get along, so oil-based exterior painting is one of the oldest forms of waterproofing in the industry. It’s dirt-resistant and harder than latex, but it’s also glossy. Whether or not that’s a plus depends entirely on your taste. Oil-based exterior painting is usually reserved for doors, trim, and porch floors. It’s high in volatile compounds, so it’s gradually losing the popularity contests it used to ace.
Latex is just as durable and UV-resistant, but it lacks the toxic fumes of oil-based rivals. Its tensile strength is higher, so it can outlast even the toughest oil-based alternatives. Ordinary latex exterior painting is known for its quick-drying properties and easy clean-up, but it still can’t rival the strength of acrylic latex—the guru of the exterior painting world.
Packing Extra Functionality into Exterior Painting
Putting together the perfect coating can become complicated enough to stymie a chemistry expert. Every paint wants to look pretty, but extra ingredients can help it to dry faster and control problems like mildew. The best paints on the shelf can prevent mold, so you can say “goodbye” to ugly blackening before it even has a chance to take hold. Additives can also give your paint extra aesthetic oomph through improved texture—a detail that means the difference between a smooth, unlined surface and a textured one. Exterior painting additives can even freshen the air with a subtle scent.
Innovative new coatings have many powers, and they’ll stick to your surfaces tenaciously in rain and snow. There is, however, no such thing as the perfect paint, only the perfect paint for your unique needs. Fresh Paint Inc. can create what seems like magic with paint, finding just the right coatings for your needs. Your building can finally become the trendsetter it’s always wanted to be while being well protectect from the elements.
