The best way to glue glass: An overview

Gluing glass together can be a challenge because many types of glue will not bond to its smooth, non-porous surface. Even some super glues will not adhere to glass. Not to worry, though; there are adhesives that will work for this application, and we’ll give a brief overview here. Then we’ll list some suggestions on the best glues for your projects.

How to glue glass back together: Small projects and repairs

A specialty glass repair glue is best for repairing small items and household goods such as wine glass stems, knick-knacks, and other indoor items. Choose one that dries clear, works with all types of glass, and is dishwasher safe.

How to glue glass: Medium projects

If you have a larger project in mind or need an adhesive that will fill the gaps where small shards of glass may be missing, then epoxy is probably your best bet. Epoxy can act as an adhesive, filler, or laminate to repair surface issues and scratches.

Most epoxies dry clear but can be tinted to match coloured glass.

Best way to glue glass on large projects

A clear construction adhesive formulated for glass is the best choice for large-scale projects such as plate glass, large windows, and specialty projects. Make sure the glue you choose is rated for outdoor use if it will be exposed to the elements.

How to glue glass to glass: Step-by-step instructions

Here are the basic steps to glue glass with a glass adhesive. Using epoxy is similar but remember the additional step of mixing the two parts of the epoxy on a disposable surface before you begin.

  1. Wash the surfaces to be bonded with glass cleaner or soap and water. Allow all materials to dry completely before beginning your repair.
  2. Ensure all parts are close-fitting.
  3. Apply the adhesive sparingly to one surface. Just one drop of adhesive will cover up to 6.5cm2 of glass.
  4. Press the parts together immediately and hold them in place for one minute or until the bond begins to hold.
  5. Leave overnight for full cure. The item will be dishwasher safe in one week.

Cleaning up excess adhesive: if you have a drip or run of excess glue as you are working, a damp cloth is usually all you need to wipe it away. Cured adhesives can be carefully scraped away with a razor, then use acetone to remove the remaining residue.
