Default How To Repair Cracked Plexiglass

Any suggestions on how to repair cracked plexiglass? I have a 3 inch crack in a 1 piece storm window. It starts at the edge so I was thinking maybe spread it apart and use crazy glue?

Plexiglass Acrylic Glue - IPS Weld-On & Plastic Adhesives Online

I would do a bit of checking on which adhesive is best for the type of acrylic you have. There is a decent guide on this link.

Mask as close as you can to the crack to avoid the glue from 'melting' the surface of the acrylic when it squeezes out.

Thank You. I looked at their web site and will give them a call next week.

I would replace the Plexiglass with clear Lexan. It doesn't break. They make bullet proof windows from it, although those are much thicker than you will need. (Don't expect 1/8" Lexan to stop a bullet).

agreed but it is nick sensitive as is plexi...

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

A cop told me that 1/4" Lexan would stop a 30-30. He used it behind his uniform shirt.

Maybe a BB gun lol .
On myth busters they shot a box made out of 1" lexan and the 30-30 went threw both sides like it was butter . Would stop small arms fire though .

And the only window that will stop a 50 cal is 1.6" thick transparent aluminum .

I don’t always insulate , but when I do .
Ok ,I never insulate

Drill a small hole at the end of the crack or it may keep running. The hole distributes the stress.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
