Finding the ideal coatings for your structure is crucial in determining the longevity of your surface. You can consider Polyurea coatings for their unique advantages, making them superior to most protective coatings. Although there are specific requirements and limitations when applying, they guarantee more protection and other outstanding features. Here is everything you need to know about Polyurea coating and how to apply it.
Polyurea coatings consist of a lining and joint sealing technology to guarantee your structure's surface protection. The rugged synthetic polymer technology featured in the coating makes it ideal for waterproofing, among other advantages. You can rely on Polyurea coating for excellent chemical resistance, water-tight qualities, and abrasion resistance on surfaces with intricate details like flooring and flat floors.
Polyurea coating guarantees increased durability through improved tear resistance and excellent tensile strength. One outstanding benefit of Polyurea is its endurance to heavy foot traffic because of its tear resistance. Not many coatings guarantee incredible tensile strength like Polyurea.
One of the main reasons Polyurea coatings are superior is because they heal quickly, contributing to fast installations. The layer takes less time to dry compared to other alternatives. It takes less than 24 hours for it to cure completely (1).
According to several professionals, you can live with Polyurea coating without needing maintenance for life. Most floor coatings require frequent maintenance and re-coat due to minor damages.
Polyurea coating can withstand extreme temperatures, abrasions, and chemicals. Clean-ups are also a breeze because of their non-porous texture. No longer will you have to worry about stains; a single surface wipe is enough.
Polyurea coating is a favourite for garage surfaces because of its strength and durability. Thanks to the coatings' tough nature, your surface can withstand any hard impact without cracking. Water and chemical resistance are also benefits guaranteed from using Polyurea coating on your surfaces.
Exposure to chemicals is a common factor that contributes to damaging your surfaces. Various tests conclude that Polyurea coating is resistant to solvents and acids, including acetic and hydrochloric acid. These chemicals are primarily found in garages, airplane hangars, and repair shops, making the coating ideal for such premises.
Another benefit of using Polyurea coating on your surfaces is its UV resistance. UV light is the main reason most plastic items fade or turn yellow. Polyurea coating is the perfect option for outdoor applications to protect your floors.
The slip-resistant nature of Polyurea coating is another factor that contributes to its efficiency and effectiveness. It guarantees to make your garage floor safe to navigate even when wet. Some Polyurea coatings contain chips to help give extra traction, reducing slips and falls significantly.
The chips featured in Polyurea coating also create a unique and granite-like appearance on your floor. You can use it to make your garages more like a showroom.
Surface Preparation
The first step to applying Polyurea coating is preparing the surface. Here is how to prepare specific surfaces;
Mineral Surface
The concrete structure must be more than 28 days when preparing mineral surfaces. You should also consider using abrasive blasting to remove all foreign bodies and ensure a clean surface. If it is a heavily loaded area like rooftop car parks, use kiln-dried quartz sand to lightly mineral-surface the primer layer.
Wooden Surface
All wooden surfaces should be clean before you apply Polyurea coating. Use 100 to 150 grams of the coating per square meter on a wooden surface and avoid uneven thicknesses.
Metal Surface
The metal surface needs to be clean before Polyurea coating application. Foreign elements like oils, fats, and dirt can negatively affect adhesion.
Applying Polyurea Coating
Applying Polyurea coating is known as "hot spray" because of the optimal temperature of 60-70°C (2). The Polyurea coating only takes a few seconds to react with the surface.
The Polyurea coating process involves spraying the coating through heated hoses. Using a spray gun ensures the spraying process achieves the required heat before leaving the firing hose. It also guarantees the best physical properties your protective coating can attain. For the best results, we recommend using roofing specialists.
How to Spray Polyurea Coating
• Start with detailing and spraying the perimeter.
• Spray the existing roof's overlaps and seams.
• Spray Polyurea coating to the rest of the roof.
• Protect the coating from UV radiation by applying a solar reflective top coat.
