Term: roller

In painting, a "roller" refers to a tool used to apply paint to large, flat surfaces quickly and evenly. It typically consists of a cylindrical core covered with a fabric or foam material (called a nap or cover) that absorbs and distributes paint. The roller is attached to a handle, which may be extended with a pole for reaching high or distant areas.

Key components of a roller:

• Roller frame: The metal or plastic structure that holds the roller cover and attaches to the handle.
• Roller cover (nap): The fabric or foam sleeve that holds and applies the paint. Different nap lengths are used depending on the surface texture (e.g., short nap for smooth walls, long nap for rough surfaces).
• Handle: The grip used to control the roller, often threaded to accept extension poles.

Common uses:

• Painting walls, ceilings, and other broad surfaces.
• Applying primers, undercoats, and topcoats.
• Suitable for both water-based and oil-based paints, depending on the roller cover material.

In the Australian painting industry, rollers are a standard tool for professional painters due to their efficiency and ability to produce a consistent finish.
