How to Glue Plastic to Glass

Updated January 12, 2019

Space-age technology has made all sorts of things possible, from home repairs that used to require a contractor, to crafts that demanded an artisan. One of the most fun advances has been in the science of how to stick things to other things. If you are trying to glue plastic to glass, you are in luck. Whether you are reattaching a rear-view mirror or making beaded glass ornaments or gifts, there is an adhesive made just for you. Sticking plastic to glass could not be simpler.

  1. Clean the glass you intend to use thoroughly with glass cleaner and a soft, lint-free cloth. Removing any dust or oils ensures a tighter bond.

  2. Sand very smooth plastic with 120-grit sandpaper before attempting to attach it to glass. The slightly rough surface gives the glue more to hold onto.

  3. Plug in your hot glue gun, insert a glue stick and let it warm up. Squeeze a little onto some scrap cardboard to get the feel of how much pressure to use, and then apply the glue to the plastic. Stick the plastic to the glass and let the hot glue cool for 30 seconds to 1 minute. This technique is best for making beaded ornaments and other things that will not be handled or washed too often.

  4. Apply a tiny bead of ultraviolet glue to roughened plastic and then attach it to the glass. Press firmly. Set the glued pieces in direct sunlight and let them sit for 2 to 4 hours.

  5. Squeeze a tiny dot of clear-drying silicone-based glue to roughened plastic and then adhere the plastic to your glass. Let it dry according to the manufacturer's instructions.

  6. Apply a tiny bit of epoxy to the point of a straight pin. Smear this dot onto the back of a plastic rhinestone or bead and touch the pin to the glass you are attaching the plastic jewel to. Hold the rhinestone against the glass as you carefully slide the pin out from between it and the glass.

  7. Tip

    Keep a bowl of ice water handy when using a hot glue gun to soothe any accidental burns.


    Never used silicone-based glue on drinking glasses, serving plates or anything else that will come into contact with food, as it is highly toxic.
