What type of surface finish might jointers be used to achieve on a masonry wall?

Jointers are tools used in masonry to shape and finish mortar joints between bricks or blocks. The primary purpose of using a jointer is to create a smooth finish on the mortar joints, which can enhance the aesthetic appeal of a masonry wall. A smooth finish helps to create clean lines and can contribute to a more polished overall appearance of the structure.

When jointers are used, they compress the mortar and create a uniform surface, which not only looks visually appealing but also helps in preventing moisture penetration. This is particularly important in masonry construction, as moisture control can significantly affect the durability and longevity of the wall.

While some textures may be desirable in certain architectural styles, the essential function of a jointer is to smooth out the joint rather than leaving it rough, glossy, or heavily textured. Thus, in this context, a smooth finish is the appropriate outcome associated with the use of jointers in masonry work.
