Red Seal Bricklayer Practice Exam

Using a pointed chisel carefully when removing old mortar is the best practice because it allows for precision and minimizes damage to the surrounding bricks. This method enables the bricklayer to target specific areas of mortar without compromising the integrity of the bricks or the overall structure. A pointed chisel can effectively chip away at the hardened mortar, creating a clean joint that can be re-pointed.

The use of a power tool, while faster, can lead to excessive vibration and potential damage to the bricks, making it a less desirable option. Additionally, removing mortar without regard for the bricks can result in significant damage, weakening the masonry and leading to expensive repairs. Removing mortar only when dry may seem like a practical approach; however, if the mortar is too hard or brittle, it may be more challenging to remove without risking damage to the bricks. Thus, the careful use of tools is paramount in maintaining the bricks’ integrity while ensuring effective and efficient mortar removal.
