What are the best practices for applying foundation caulk to ensure a seamless and durable finish?

To apply foundation caulk effectively, start by cleaning the area thoroughly and ensuring it is dry. Cut the caulk tube nozzle at a 45-degree angle and apply a smooth, even bead along the joint. Use a caulk tool or your finger to smooth out the caulk and remove excess. Allow the caulk to dry completely before painting or exposing it to water. This will help create a seamless and durable finish.
