What is the first step in laying the first course of bricks?

Laying the first course of bricks is a crucial step in masonry work, and ensuring that the footing is level and flat is essential for a proper foundation. A level and flat footing ensures that the bricks will be laid evenly, which is critical for maintaining the integrity of the structure. If the footing is not level, it can lead to uneven rows of bricks, which can compromise both the aesthetics and stability of the wall. A solid and level footing also prevents shifting and settling of the bricks over time, which can cause cracks and other structural issues.

Other options, while important in the overall process of masonry, do not address the foundational requirements needed before laying the first course. Mixing mortar and preparing it correctly is vital, but it should be done after confirming the footing is ready. Cutting bricks to size is also important but is typically a step that comes after establishing the first course and assessing the need for adjustments to fit specific designs. Ensuring a proper, level, and flat footing ultimately sets the stage for successful bricklaying.
