How to Install Rear Window Perforated Decals

Rear window perforated decals are an excellent way to advertise your business, showcase your style, or simply add a personal touch to your vehicle. These decals allow you to display vibrant images on the outside while maintaining visibility from the inside. Installing them properly is crucial for both aesthetics and functionality. Here’s a step-by-step guide to help you install your rear window perforated decal like a pro.
Materials Needed
- Rear window perforated decal
- Microfiber cloth or lint-free towel
- Spray bottle with a mixture of water and a few drops of dish soap
- Squeegee or credit card
- Utility knife or razor blade
- Masking tape
- Measuring tape
Step 1: Prepare the Window
- Clean the Surface: Start by thoroughly cleaning the rear window. Use glass cleaner and a microfiber cloth to remove all dirt, dust, and grease. Ensure the surface is completely dry before proceeding.
- Check for Defects: Inspect the window for scratches or imperfections that could affect the decal’s adhesion.
Step 2: Position the Decal
- Align the Decal: Hold the decal against the window to determine its placement. Use masking tape to temporarily secure the top corners, ensuring it is centered and level.
- Mark the Position: Once you’re satisfied with the alignment, use masking tape to create a hinge along the top edge of the decal. This hinge will help you maintain the position during installation.
Step 3: Apply the Decal
- Peel the Backing: Starting at the top, carefully peel away a small section of the backing paper to expose the adhesive side of the decal.
Spray the Adhesive: Lightly mist the adhesive side with the soapy water solution. This will allow you to reposition the decal if needed and reduce the risk of bubbles. - Attach the Decal: Begin adhering the decal to the window, starting from the top and working your way down. Use the squeegee or credit card to smooth the decal, pressing out air bubbles and excess water as you go. Work from the center outward for best results.
Step 4: Trim Excess Material
- Cut Around the Edges: Once the decal is fully applied, use a utility knife to carefully trim any excess material around the edges of the window. Be cautious to avoid cutting into the glass or window seals.
- Refine the Fit: Check for any areas where the decal may overlap window edges and make additional trims as necessary.
Step 5: Final Adjustments
- Remove Moisture: Use the squeegee to press out any remaining water or air bubbles. Wipe the surface with a clean microfiber cloth.
- Let It Set: Allow the decal to cure for at least 24 hours before exposing it to heavy rain or car washes. This ensures the adhesive fully bonds to the window.
Tips for Success
- Avoid installing decals in extreme temperatures; a mild, dry day is ideal.
- Take your time during alignment and smoothing to achieve a professional finish.
- If you encounter stubborn bubbles, prick them gently with a pin and smooth them out.
