What specific technique must be employed to achieve proper brick spacing?

To achieve proper brick spacing, employing specific scales is crucial because it ensures consistency and accuracy in the spacing between bricks. Specific scales are tools that provide measurements intended for masonry work, allowing the mason to maintain uniform joint sizes and alignment throughout the wall. This technique also plays a vital role in ensuring that the finished structure is not only aesthetically pleasing but also structurally sound, as uniform spacing helps distribute loads evenly and reduces the risk of structural issues arising from improper alignment.

While measuring with a tape can provide a rough idea of distances, it lacks the precision and repeatability necessary for consistent results. Similarly, using a level is essential for ensuring that bricks are laid evenly in terms of height and alignment, but it does not directly address spacing. Visual estimation, while sometimes used by experienced masons, can lead to discrepancies and is less reliable compared to the defined measurements provided by specific scales. Thus, relying on specific scales is the most effective technique to achieve the correct brick spacing.
