Step-by-Step Instructions
Step 1: Inspect Doors and Windows
Walk around your home and identify areas where you feel drafts or see visible gaps around doors and windows. These are the areas that need weatherstripping. Pay special attention to exterior doors and older windows.
Step 2: Remove Old Weatherstripping
If weatherstripping already exists, use your scraper to remove it. Scrape away any remaining adhesive residue. Clean the surface thoroughly with rubbing alcohol and a rag, then allow it to dry completely.
Step 3: Measure and Cut New Weatherstripping
Measure the perimeter of each door or window frame. Cut the weatherstripping to length using your utility knife. It's better to cut slightly longer than needed; you can trim it to fit.
Step 4: Apply Weatherstripping to the Door or Window Frame
Peel back the adhesive backing on the weatherstripping and press it firmly onto the frame. Start at one corner and work your way around, pressing firmly as you go to ensure good adhesion. The weatherstripping should fit snugly in the gap without compressing excessively.
Step 5: Seal Large Gaps with Caulk (If Necessary)
If there are gaps larger than 1/2", use your caulk gun to apply silicone caulk. Cut the caulk tube tip at a 45-degree angle to match the gap size. Apply a continuous bead of caulk and smooth it with a wet finger or caulk tool.
Step 6: Allow to Cure
Allow the weatherstripping adhesive and caulk to cure for 24 hours before opening and closing doors or windows. This ensures a strong, lasting seal.
Step 7: Test the Seal
Close doors and windows firmly and feel for any remaining drafts. If you find any gaps, apply additional weatherstripping or caulk as needed.
