Based on common painting tools and the provided reference, a roller (often the term used in painting contexts) is a tool specifically designed for applying thin, uniform and even coats of paint or other liquid finishes. It typically consists of a cylindrical cover that absorbs the finish, mounted on a handle.
Key Functions and Applications
The reference emphasizes that a roller is an ideal tool for painting large, smooth and well-prepared walls, ceilings, and large furniture. Its design allows for rapid and consistent coverage over extensive areas, which is often challenging with traditional brushes.
Why Use a Roller?
Using a roller offers distinct advantages, particularly in terms of efficiency and economy, as highlighted in the reference:
- Economical: The roller is described as being more economical to use than the brush. This is because its porous surface holds much more paint than a brush.
- Efficient: Rollers facilitate the application of paint much faster. They effectively distributes an even layer of paint much faster compared to brushes, making them suitable for covering large surfaces quickly.
In summary, while the term "roller brush" might sometimes be used, the tool commonly referred to in painting for covering large areas efficiently is a roller, known for its ability to apply smooth, even coats economically and quickly.
