Resistance to Extreme Weather
Make sure the caulk is suitable for the specific weather conditions in your area. Look for products that can withstand extreme temperatures and resist water, UV rays, and humidity. This ensures that the caulk maintains its seal and effectiveness over time.

Decide if you prefer a product that is applied with a caulk gun or one that comes in a squeeze tube. Caulk guns give you more control but can be harder to manage if you’re not experienced. Squeeze tubes are more user-friendly for quick fixes.

Drying Time
Check the drying time of the caulk. If you’re in a hurry, choose a product that dries quickly. Some caulks can dry in as little as 30 minutes, while others might take a full day.

Adhesion and Flexibility
Look for caulks with excellent adhesion and flexibility. This is important for filling gaps that might expand or contract due to temperature changes. Flexible caulk will prevent cracks and maintain a strong seal.
