Polyurethane (PU) roller coating is a widely used application method in which a PU-based coating is evenly applied to surfaces using a roller. This process is ideal for achieving a smooth, uniform finish on large, flat areas such as floors, furniture panels, or metal surfaces. Before application, the surface is thoroughly cleaned and primed if necessary. The PU coating is then poured into a tray, and a roller—often made of foam or microfiber—is used to spread the coating in thin, even layers. Depending on the desired thickness and the type of PU being used (water-based or solvent-based), multiple coats may be applied, allowing each coat to dry fully before the next is added. PU roller coating offers excellent abrasion resistance, chemical resistance, and a durable, glossy finish suitable for both industrial and decorative applications.
