What benefit does tooling provide to the wall construction?

Tooling, which involves the process of finishing the mortar joints in masonry construction, is primarily aimed at enhancing the performance and durability of the wall. One of the significant benefits it provides is the improvement of the watertight seal.

When mortar joints are tooled, they are shaped in a way that allows for better compaction and tighter sealing. This compaction reduces the porosity of the mortar, which in turn helps to minimize water infiltration. An effective watertight seal is essential for maintaining the integrity of the wall, preventing moisture damage, and promoting longevity in the structure. Proper tooling also reduces the likelihood of cracks forming in the mortar over time, further enhancing the waterproofing capabilities of the masonry.

While tooling can contribute to aesthetics and possibly affect drying time due to the shape of the joint, its primary function is ensuring that the wall is well-sealed against water penetration.
