What are the different types of mortar joints?

There are many different types of mortar joints, but the main ones you would encounter on a typical residential home are flush, raked, and concave (aka jointed).

A flush finish is when the masonry joint is brought flush with the brick or masonry unit and is generally used if the masonry is to be painted to give walls a more uniform look.

A concave finish is the most common mortar joint as it produces the best weather protection.

Raked joints are another finish where the mortar joint is recessed about 3/8th of an inch having each brick stand out more compared to the uniformity of a flush or concave finish.
