Jointing (Bricklaying)

As a bricklayer, one of the most important skills you need to learn is jointing. Jointing is the process of creating a smooth and aesthetically pleasing finish on the mortar joints between bricks or concrete blocks. It involves using a specialized jointing tool, typically made of metal or durable plastic, to shape and compress the mortar into the desired shape.

The mortar itself is a mixture of Portland cement, hydrated lime, and masonry sand, and it is used to bind the bricks together. Mortar joints can be either concave or flush, depending on the look and feel you want to achieve. A concave joint has a curved indentation that forms a recess between the bricks, while a flush joint is completely flat with the surface of the brick.

There are several different techniques that can be used to joint bricks, including flush pointing, weathered pointing, and tuckpointing. Flush pointing is the simplest and most basic technique, and involves creating a flat, even surface on the mortar joint. Weathered pointing involves creating a sloping surface that channels water away from the wall, while tuckpointing involves using a contrasting mortar color to create the appearance of a finer, more detailed finish.

Regardless of the technique you use, jointing is an important part of the bricklaying process. It not only improves the overall appearance of the finished product, but it also helps to protect the wall from water damage and other types of wear and tear. So if you're looking to become a skilled bricklayer, mastering the techniques of jointing should be at the top of your list.
