Red Seal Glazier Practice Exam

A putty knife is specifically designed for the task of removing old glazing from a frame, making it the ideal tool for this job. Its flat, flexible blade allows for effective maneuverability along the frame's edges, enabling the user to carefully scrape away the old putty without damaging the surrounding material or glass. The blade’s design minimizes the risk of gouging the frame, which could lead to further repair needs.

While a hammer, chisel, or pry bar might be useful in other situations, they are not typically suited for this delicate task. A hammer could cause unintentional damage to the frame, and a chisel, while it can remove material, lacks the same level of control as a putty knife for this specific application. A pry bar is more geared towards leverage rather than precision, making it less appropriate for carefully removing glazing. Thus, the putty knife stands out as the most effective and safe choice for the removal of old glazing.
