A spiked roller is a type of roller that has spikes or studs on its surface, used in coating applications. The spikes help to ensure even application of paint, coatings, adhesives, or other materials. The spikes also help to reduce the amount of material that is absorbed into the substrate, leading to a more efficient use of the coating material. Spiked rollers are commonly used in industrial, commercial, and residential painting projects, and can be made from a variety of materials such as foam, rubber, or plastic.
