A pebble from your lawnmower hitting your windshield, a heavy drink on the table, or a favorite vase accidentally being tipped over: these are the kinds of incidents that can lead to cracks in glass around the home. While these cracks may seem minor, they can jeopardize the structural integrity of the window and allow drafts and water to seep in. Luckily, fixing cracked glass is easy with the right materials and a little bit of patience. In this article, we’ll explore various methods for repairing glass cracks, from using epoxy to other DIY techniques.
Before you can successfully repair your glass, you need to understand the cause of the crack. This is important because stress cracks that appear spontaneously are caused by temperature changes and pressure, while impact cracks are usually caused by external force like objects striking the glass. Once you know the type of crack you’re dealing with, you can choose the best repair method.
Tape is a great temporary solution for cracked glass. It can hold the pieces of glass together and help make a cracked window look less noticeable. If the crack is small enough, you can also use clear tape to seal it and keep out rainwater and drafts. However, you should note that the crack will still be visible and the tape isn’t as strong as a patch.
An alternative to simple tape is glass repair film, a special material sold in do-it-yourself repair kits that’s designed to fill and cover the crack. Glass repair film is easier to apply than a traditional patch, and it offers a more durable solution that can help prevent further damage. This option can be used for cracks in windshields, windows, and other types of glassware, but it’s not recommended for double-paned windows as it will compromise the gas layer that keeps them insulated.
If you want a more permanent fix, you can also try applying a resin-based adhesive. This type of adhesive is stronger than most household glues and comes in a variety of viscosities. Most require the user to mix equal parts of resin and hardener, and you should stir the adhesive for about 20 seconds to ensure a strong bond. Afterwards, the adhesive must be left to dry, or “cure,” for a few hours. During this time, you should clamp the glass with lightweight clips designed specifically for holding fragile materials to avoid accidental breaks or shifts in the repaired area.
Once the epoxy is cured, you can remove the clips and clean up any excess residue from the glass with a razor blade or putty knife. It’s important to do this carefully so you don’t scratch the glass. Alternatively, you can leave the excess epoxy to slowly dissolve over time.
Once the repair is complete, you’ll need to check that it’s safe to use. Check the cracked glass for any weak points or loose areas and give it a light tap to ensure that it feels solid.
