Select Caulk and Prepare for Application

What happens here

Begin by selecting the appropriate caulk for exterior window and door sealing. The video recommends 'Big Stretch' caulk due to its excellent elasticity and ability to span large gaps, which is crucial for older homes or those with previous DIY work. 'Tower Tech' is also mentioned as a suitable alternative. Ensure your caulk gun is loaded and the caulk tube's tip is cut at a 45-degree angle. This angled cut is essential for creating a smooth, consistent bead and effectively filling wide gaps. Wearing gloves is highly recommended to protect hands from chemicals in the caulk.

Goal: Choose a high-quality caulk designed for exterior use and large gaps, such as Big Stretch, and ensure your caulk gun is properly prepared for application.
