OT-what's a good glue for plastic???

Ray · Oct 24, 2011

I've got a big old sign made from plastic that has some cracks.The biggest is about a foot long.
Is there any good glue that will fill the cracks and hold? Thanks.

I bought some new glue thats out for a couple repair jobs on plastic & rubber . Its called Gorilla Super Glue . It"s nothing like the old super glue that sticks immediately & sometimes causes problems . This Gorilla glue sets up slower giving a person some time to make those last second adjustments . Plus when you put the cap back on & then wanta use it again later , the caps screws off & the glue still flows out the end of bottle (which is a plus). Give it a try . HTH ! God bless

To prevent further cracking, put it on a support. (assumes it is not back lit).
T-3 aluminun at about .100" is great.
Use epoxy for plastic. (menards. Home Depot) If it is back lit, use lexan polycarbonate (not plastic sheet) and glue with 3M trim cement 77. Jim

From my experience nothing will stick to plastic, for very long. stan

Identify the plastic. Then the repair can be planned. Your sign is not likely to be polyethylene or polypropylene. Those cannot be glued, only welded or mechanical fasteners. Epoxy works well on some plastics, but not all.

Google "German glue" I've used it for years, Best stuff for "ANY" plastic And most other things also Jim in N M

If you have some of the plastic material, make some shavings and mix it with acetone. As the shavings melt, mix with the acetone and make a paste. Then, use the paste as a glue.
