Bookbinding Tools
Choose a brush, roller or spatula by where the glue goes
A thin line near a hinge and a full sheet of cover material call for different contact widths. Choose a head you can control in the area, then check its stated compatibility with the adhesive you use.
Narrow work near a joint
A smaller brush gives you space to work beside a fold. A micro spatula can help you reach a narrow area with its tip. Compare the actual tip width and profile, and check how the tool approaches the joint on a scrap assembly.
Broad work across a cover
A wider brush or roller covers more area in each pass. Check the roller width and the material of its contact surface before choosing it for a particular adhesive. The method instructions may call for a brush on some pieces even if a roller is convenient on a larger one.
Plan the changeover between materials
Read the tool and adhesive instructions for cleanup. When the instructions leave the pairing unclear, test on a scrap or use an applicator the maker documents for that material. Compare the cost of a dedicated head if changing jobs often would interrupt the work.
