Applying and Tooling Flexible Caulk

What happens here

Once the backer rod is in place (for wider gaps) and surfaces are primed, apply a steady, continuous bead of flexible caulk, such as Tower Tech 2, along the cracks and joints. Maintain consistent pressure on the caulk gun to ensure an even flow and complete filling of the gap. After application, immediately tool the caulk with a gloved finger. This step is crucial for pressing the caulk firmly into the joint, creating good adhesion to the sides of the crack (and the backer rod if used), and achieving a smooth, professional-looking finish. The video highlights that tooling with a gloved finger helps clean your hands and creates a neat appearance, indicating a good understanding of caulking techniques.

Goal: Apply a continuous bead of high-quality, flexible caulk into the prepared gaps, ensuring it fills the joint. Immediately tool the caulk with a gloved finger to create a smooth, clean finish and ensure proper adhesion to the substrate.
