What is the process of placing the mortar on the course that has been laid?

The process of placing the mortar on the course that has been laid is best described as spreading mortar. This involves taking the mortar and evenly distributing it over the bricks or blocks that have already been set in place. Spreading ensures that there is a consistent layer of mortar to bond the next course of masonry to the preceding one, which is crucial for the structural integrity of the wall.

Using the correct amount and achieving the right consistency when spreading mortar is vital; it helps to create a strong bond between masonry units, ensuring they are securely held together while also allowing for adjustments during the installation process. This phase of masonry work is fundamental in ensuring that walls are plumb, level, and structurally sound.

The other terms do not accurately represent this specific process: applying implies just the action of putting mortar down without specifying the method, setting refers to allowing the mortar to cure, and finishing usually involves the final touches to the mortar joints once the masonry is assembled. Each of these plays a role in the overall masonry process, but they do not pinpoint the act of spreading mortar on the laid course.
