How to Stop a Crack From Spreading in a Glass Top Table

Updated February 21, 2017

Glass top tables are both attractive and functional pieces of furniture. In general, glass that is used in furniture, such as tables, is thick enough to withstand minor bumps and jars. However, they are susceptible to cracks if enough pressure is applied. Once a crack develops in a glass table, it will spread the next time even slight pressure is placed on it. To prevent the crack from spreading, you must fill it in to bond it together.

Remove all items from the glass table and move it to well-ventilated location, or open any windows in the room.

Put on disposable gloves and apply 2 to 3 tablespoons of acetone to a lint-free rag. Wipe the entire surface of the glass with the acetone to clean it and remove grease or dirt that will otherwise interfere with the adhesion of the filler. Do not use any other cleaner, or glass spray on the table since these leave a residue.

Install a ball-tip bit into a drill and create a small hole in the glass table 1/8 inch from both ends of the crack. The holes should not go all the way through the glass, but extend only as deeply as the crack or half the depth of the drill bit.

Insert a bullseye tool into both holes you drilled and tap it once with firm pressure using any solid object. This creates a depression at the bottom of the holes, which hold the resin.

Locate the plastic adaptor from the windshield repair kit and peel off the backing to expose the adhesive. Center the adaptor over the centre of the crack and push down firmly.

Insert the syringe of resin into the top of the adaptor. Pull back on the syringe handle and hold for 60 seconds to suck air out of the crack. Then release the handle to push the resin into the crack. Repeat the process five or six times until you see the crack disappear.

Pull off the syringe and the adaptor. Apply 2 to 3 teaspoons of rubbing alcohol onto a paper towel and wipe off the glass table to remove any resin that was spilt. Do not wipe directly on top of the crack repair.

Allow the resin filler to dry for the amount of time indicated on the package, or until it is completely hard to the touch. Place a sharp razor blade flat on the surface of the glass table and push it over the top of the crack with force to scrape off the excess resin.


Always read the instructions on the repair kit carefully, since they vary slightly in the application methods.
