Polyurethane floor coating is synthesized from polyether polyols, polyisocyanates, chain extenders, curing agents, fillers, anti-aging agents, and other components. Featuring excellent physical and mechanical properties, resistance to weather, UV light, polyurethane floor coatings are widely used in applications that need to withstand high level of foot traffic and heavy machine movement, including industrial and mining workshops, parking lots and sports facilities.
In comparison to epoxy floor coatings, polyurethane flooring presents higher durability and abrasion resistance, which make it widely used in some applications where epoxy may not be suitable. To be specific, epoxy floor coatings are prone to cracking and yellowing when used outdoors. In contrast, polyurethane floor coatings are well-suited for both indoor and outdoor applications, showcasing resistance to cracking, UV lights and able to maintain glossy and intact even being subjected to scratches of knifes, glass and rock, etc.
What’s more, clear polyurethane coat can be applied over an epoxy floor primer, serving as a protective layer against scratch and abrasion.
For industrial venues such as mechanical factory workshop, the floor coating must possess excellent wear resistance and the ability to withstand heavy pressure from large machinery movement. Polyurethane floor coatings, capable of enduring high intense traffic loads, exhibit remarkable toughness in the face of impacts from falling objects or deformation.
Polyurethane floor coatings come in high-gloss, matte, and semi-matte finishes, suitable for a variety of industrial floors as well as commercial flooring applications in places like hospitals, subway cars, libraries, and more. These coatings add a decorative touch to the floor surfaces, eliminating the need for waxing and polishing while maintaining a glossy and attractive appearance.
Polyurethane coatings, when infused with anti-slip agents, offer excellent skid resistance and find versatile applications in parking lots, workshops, hospitals, sidewalks, and pedestrian overpasses. This enhanced slip resistance makes polyurethane coatings an ideal choice for various flooring needs.
In parking lots, anti-slip polyurethane provides added safety, reducing the risk of vehicles skidding in wet conditions. In industrial workshops, applying anti-slip polyurethane ensures a more stable environment for workers operating machinery. For public spaces like sidewalks and pedestrian overpasses, anti-slip polyurethane coatings play a crucial role in ensuring safe walking conditions for pedestrians, regardless of weather conditions.
Polyurethane elastomeric track flooring is flexible and bouncy, giving people standing for a long time the comfort they need. It also cuts down on the noise when people walk on it. Because it bends back into shape and resists scratches, polyurethane flooring stays looking fresh and new for a long time, making it a good choice for places like tennis courts, sports fields, and regular running tracks.
Featuring excellent abrasion resistance, polyurethane coatings can help extend the longevity of hardwood floors by protecting the substrate against the infiltration of moisture, dirt, and other liquids that may otherwise pose risks of swelling and warping. Furthermore, these coatings can enhance the aesthetic appeals by forming a vibrant, smooth, and glossy appearance.
Installing polyurethane floor coatings involves several steps to ensure a proper and durable application.
To start this transformation, the first step is making sure your existing floor is spotless. Clean away any dust, dirt, or other stuff that might get in the way. If there is cracks on the floor surface, fix it using epoxy resin combined with quartz sand for patching and smoothing. Then, consider using diamond grinding pads to grind the floor to remove surface irregularities, rough spots, or existing coatings.
For the treatment of the floor, a penetrating sealer (primer) is employed, utilizing polyurethane material. This process is applied to a floor that has undergone shot blasting and thorough cleaning. Depending on the sanding condition of the floor, the penetrating treatment is applied 1 to 2 times.
In the application of the mid-coat layer, the primary material used is the mid-coat material with quartz sand as an auxiliary component. Once mixed, it forms a putty, applied in four full batches on the floor.
After completing the above procedures, the floor surface has achieved a dense and smooth texture without noticeable traces of construction tools, insect or damage. The surface is now prepared for the application of the topcoat. Apply the topcoat material in two layers to achieve the desired finish.
