Does tooling the caulk serve any purpose beyond aesthetics?

Tooling the caulk serves multiple purposes, and one of the primary benefits is enhanced adhesion. When caulk is tooled, it creates a smoother surface that better bonds with both the substrate and the surrounding materials. This improved adhesion is crucial, especially in areas where moisture or movement may occur, as it helps maintain a tight seal over time.

In addition to enhancing adhesion, tooling also allows for better control over the amount of caulk applied and helps achieve a smooth finish, which can contribute to longevity and effectiveness. While aesthetics are certainly a consideration, the functional aspects, including improved adhesion, make tooling an important step in the caulking process. The other responses suggest that the only benefit is visual or that tooling is not necessary, which overlooks these critical functional advantages.
