What does 'racking' refer to in the context of brick installation?

1. The mixing of mortar

2. The process of laying and adjusting bricks to form a pattern

3. The application of paint on the bricks

4. The measurement of brick sizes

The correct answer is: The process of laying and adjusting bricks to form a pattern

Racking refers specifically to the process of laying and adjusting bricks to form a pattern during installation. It involves arranging the bricks in a manner that ensures both structural integrity and aesthetic appeal. This technique is vital for achieving a uniform appearance and maintaining the intended design layout of the masonry work. In brick installation, racking may involve aligning bricks to achieve consistent joints and ensuring that the pattern matches the design specifications. This careful placement is essential for achieving a quality finish and ensuring that the walls are both visually pleasing and structurally sound. Understanding racking is crucial for bricklayers as it affects not only the overall appearance of the constructed wall but also its durability and performance. The other options provided do not relate directly to the process of laying bricks, which reinforces why racking specifically pertains to the arrangement and adjustment of bricks.
