What is the correct procedure for dipping bricks in mortar when laying firebrick?

When laying firebrick, the proper procedure for dipping bricks in mortar is to dip one end of the brick and wipe the bottom. This method ensures that the mortar adheres well while preventing excessive mortar from accumulating, which can lead to uneven surfaces or weaken the bond between the bricks. By only dipping one end, it allows for greater control and precision during the installation process.

This technique also helps to maintain the integrity of the firebrick and the overall structure as it minimizes the possibility of "squeezing out" too much mortar during placement, which can happen if more area is covered than necessary. Proper wiping of the bottom further ensures that the brick will sit flat and securely on the surface, allowing for effective thermal management and structural stability, especially critical in applications involving intense heat.
