Staple Gun
Definition
A Staple Gun is a handheld tool designed to drive staples into a substrate. In the context of picture framing and canvas work, it is primarily used to secure and stretch canvas around a Strainer Bar or stretcher frame, ensuring a tight, even surface for painting or display.
Purpose
- Efficiently attaches canvas to stretcher bars for painting or framing.
- Provides a consistent, firm grip along the edges of the canvas.
- Reduces manual labor compared to hammering individual tacks.
Common Techniques
- Stretching canvas evenly using Canvas Pliers before stapling.
- Placing staples at regular intervals along the back edges of the Strainer Bar to prevent sagging.
- Using a controlled trigger pull to avoid tearing or puncturing the canvas.
Considerations
- Choose the correct staple size for the thickness of the canvas and stretcher bar.
- Maintain even tension across all sides to avoid warping or uneven surfaces.
- Staple guns can be manual, electric, or pneumatic; each offers different speed and force control.
