Step-by-Step Guide to Caulking Exterior Windows

Step 1: Inspect and Prepare Your Windows

Inspect the old caulk and remove anything that is damaged or worn. Clean the surfaces to be caulked thoroughly to ensure optimal adhesion of the new caulk.

Step 2: Choose the Right Caulk

Depending on your climate and window type, choose a caulk that will withstand local weather conditions.

Step 3: Apply the Caulk Properly

Cut the tip of the caulk tube at a 45-degree angle to facilitate application. Apply the caulk evenly while maintaining constant pressure on the caulking gun.

Step 4: Smooth the Caulk

Use a spatula to smooth the caulk and ensure a perfect seal. This will also help give your work a clean, professional look.

Step 5: Clean After Caulking

Once the application is complete, clean the tools and excess caulk before it dries. This will make touch-ups easier and maintain the aesthetic appearance of your window.

Tips for a Professional Finish

• Ideal Temperature: Apply the caulk in dry weather when the temperature is between 5°C and 30°C for better adhesion.
• Practice: Test your technique on a small section to get familiar with the caulking gun before starting on large areas.
