Preparing the Surface:
Begin by thoroughly preparing the surface you intend to caulk. This crucial step involves removing any dust, dirt, or remnants of old caulk. Use a caulk remover if necessary. Additionally, ensure the surface is completely dry before proceeding. A clean, dry surface is essential for the caulk to adhere effectively window door and siding.
Choosing the Right Caulk Gun:
Select an appropriate caulk gun that matches the size of your caulk tube. A well-suited caulk gun not only ensures precise application but also minimizes strain during the process. Load the caulk tube into the gun according to the manufacturer's instructions.
Applying the Caulk:
With your caulk gun ready, it's time to apply the caulk. Hold the caulk gun at a slight angle, approximately 45 degrees, and position the nozzle at the gap or crack you wish to seal. Apply a continuous bead of caulk by squeezing the trigger steadily and consistently. Maintain a smooth and even motion to ensure an unbroken seal.
