Cracked window glass can be a frustrating and unsightly problem, but the good news is that in many cases, it is possible to repair it yourself. While not all broken windows are repairable, especially if the crack is large or has already begun to spread, small cracks can often be fixed using a variety of methods. In this ultimate guide, we’ll explore the different techniques for repairing cracked window glass and provide step-by-step instructions to help you get the job done right.
Temporary Fixes for Cracked Windows
If you need a quick fix to stop a crack from spreading or to prevent further damage, there are several temporary solutions you can try:
Glass adhesive: Glass adhesive, typically used for vehicle windows, can also be effective for home windows. Simply follow the instructions provided with the product.
Nail polish or super glue: Filling the crack with a few layers of clear nail polish or super glue can help stabilize the glass until a more permanent solution can be applied.
Plastic brace: Securing a piece of plastic, such as a thick notebook cover, over the crack with tape can prevent the glass from shattering further.
Strong-hold tape: Heavy-duty tapes like masking or packing tape can hold a crack together temporarily, especially for superficial cracks like stress cracks.
Permanent Fixes for Cracked Windows
For a longer-lasting and more attractive solution, an epoxy repair is recommended. Here’s how to do it:
Clean the glass around the crack with a drop or two of dishwashing soap on a damp cloth. Wipe away any residue and let the glass dry completely.
Mix a two-part epoxy according to the manufacturer’s instructions, typically a 50/50 blend of resin and hardener. Mix for at least 20 seconds and be ready to use it immediately, as it will quickly thicken and harden.
Apply the epoxy to the crack using a putty knife, pressing it into the damaged area and working it back and forth across the crack.
Let the epoxy cure for at least five minutes, then scrape away any excess with a razor blade. Wipe the area with acetone to remove any raised epoxy.
Let the repaired glass cure for 24 hours, then clean the surface with a glass cleaner.
With proper preparation and careful application, an epoxy repair can make a crack in your window glass virtually invisible and provide a long-lasting fix.
