Roller coating is a method used to apply a uniform layer of paint or finish onto a surface using a roller. This technique is commonly employed in industries such as manufacturing and construction, where large areas need to be covered quickly and efficiently. The roller is dipped in a coating material and then rolled over the surface, ensuring even distribution. This process is often preferred for its speed and ease of use compared to traditional brush painting. It can be used on various surfaces, including wood, metal, and plastic, making it versatile for applications in furniture, automotive, and flooring industries.
