What is the main purpose of tooling the caulk during installation?

The main purpose of tooling the caulk during installation is to ensure proper adhesion and seal. Tooling refers to the technique of smoothing the caulk after it has been applied. This process helps to press the caulk into the joint or gap, which enhances its bonding to the surfaces being sealed. By tooling the caulk, you create a more effective seal that can prevent air and moisture infiltration, which is crucial for maintaining the integrity of the installation.

While aesthetic considerations and a professional appearance are important, the primary reason for tooling is its function in improving the performance of the sealant. It ensures that the caulk fills the joint completely and adheres properly to all surfaces, maximizing its effectiveness and longevity.
