In the simplest sense, exterior coating is a substance designed to create a watertight seal over an exterior surface, such as your home’s siding. There are numerous types of exterior coating today, many of which are easily mistaken for regular paint. But while paint technically counts as exterior coating, it offers nothing more than a quick change of exterior color or a way to brighten up an existing palette. With exterior coating, however, you don’t only get to breathe new life into your home’s exterior, but you also get to enjoy other benefits, including improved water resistance and energy efficiency.
Advantages of Exterior Coating
Let’s take a closer look at some of the advantages of exterior coating that regular paint might fail to provide:
- Water Resistance – While thick layers of paint can prevent moisture from seeping through your siding, it still won’t be completely waterproof. Constant wear and tear from the elements can gradually erode painted surfaces, eventually allowing water to seep through. Some types of exterior coating, on the other hand, help form a watertight barrier over your siding’s surface once it properly sets. Top-quality coatings also allow homes to breathe by allowing for evaporation to happen from the inside while pushing back external moisture.
- Energy Efficiency – Although light-colored paint may help reflect the sun’s UV rays, some of these damaging rays can still end up getting absorbed by your home. An accumulation of these rays can cause your living spaces to heat up, resulting in unstable indoor temperatures. Fortunately, some special exterior coatings can help reflect more ultraviolet (UV) rays away from your exterior, helping keep passive heating at bay to improve home energy efficiency.
- Extended Lifespan – Regular paint usually shows signs of bubbling or cracking within just a couple of years, requiring repainting every five years at least. Due to its specialized formulation, exterior coating can easily last twice or thrice as long while still looking good as new. Some topnotch options can even last for as long as 20 years with proper maintenance.
- Maintenance Ease – Since most exterior coatings have water- and UV-resistance properties, they’re less likely to suffer from problems associated with paint, such as peeling and cracking. This makes for a low-maintenance exterior that will protect it from moisture damage for many years.
