Red Seal Bricklayer Practice Exam

Soaking bricks before laying them is primarily done to prevent moisture absorption by the mortar. When bricks are dry, they can absorb water from the mortar when they are laid, which can lead to a weak bond between the mortar and the bricks. This absorption makes the mortar dry too quickly, potentially compromising its strength and integrating ability with the bricks.

When bricks are soaked, they are saturated with water, which minimizes the amount of moisture the mortar needs to supply when the bricks are laid. This helps to ensure that the mortar maintains the right consistency and curing conditions, allowing it to develop proper strength as it sets. Consequently, this practice significantly enhances the durability and sturdiness of the finished structure.

The other options do not accurately reflect the main purpose of soaking bricks. Enhancing appearance is not a primary concern relating to the functionality of strength and bonding. Reducing weight does not apply, as soaking bricks does not significantly change their weight in a meaningful way for construction purposes. Also, increasing drying time is contrary to the intended effect, as the goal is to have the mortar cure optimally rather than delay the process.
