What are the primary tools used by painters and decorators?

The primary tools used by painters and decorators focus on applying paint and finishes to surfaces. Brushes, rollers, and spray guns are essential for the application of paint. Brushes come in various sizes and types to suit different painting techniques and details, while rollers are commonly used for covering larger areas quickly and evenly. Spray guns are advantageous when a smooth, even coat is desired, especially in more intricate or hard-to-reach spaces.

Drop cloths are another vital tool in a painter's arsenal. They protect floors and furniture from paint splashes and spills, ensuring that the workspace remains clean and the surrounding areas are safeguarded.

In contrast, the other options list tools that are more suited for construction, carpentry, or general handyman tasks rather than specifically for painting and decorating. Consequently, the tools identified in the correct answer play a direct role in the profession of painting and decorating, making them the most relevant choice.
