Do you need reliable glue for your next DIY project? Or perhaps you need to fix something you broke recently? There are several types of glue out there tailored to sticking plastics together. However, it can be difficult to know which is the best glue for plastic that suits your needs.
Some glues work differently on different types of plastics, while others vary in drying time or durability. If you need something quick and reliable, check out Testors Cement Glue.

There are three types of glue to consider: polystyrene cement, super glue and epoxy glue for plastic.
Polystyrene cement melts the plastic slightly, effectively gluing the pieces together into one. It's great for things like pipes or model kits, but if not used correctly, it can damage surfaces. It only takes about a minute to set and is fully cured within eight hours.
You can use super glue (or cyanoacrylate adhesive) to bond a wide range of materials. It dries fast but doesn't fill up much space in between. So if you need a thicker bond for gap filling, super glue is not the way to go. It only takes 10 seconds to set and about 24 hours to cure.
Epoxy glue is a two-part glue that relies on the combination of two chemical components to create an incredibly strong plastic bonder. Regardless of how long it takes to dry, leave epoxy glue to cure for at least 72 hours. This can take longer depending on the job and climate.
Since plastic is not a porous material, it can be tricky to find the right glue to hold your plastic together. Epoxy glue works best for most plastics, but if your project requires a more flexible bond, you'll want an acrylic-based glue.
First and foremost, make sure to pick the best glue for the type of plastic you're working with. Consider if the glue will be exposed to any extreme elements or temperatures since this could impact its effectiveness. Finding the best glue for the job will ensure optimal plastic bonding.
Before you start gluing, make sure all the surfaces you intend to join are clean. You don't want dirt or grime getting in the way, and it can also impact the effectiveness of the glue’s performance.
Less is more when it comes to using strong glues. If you apply too much, you run the risk of longer drying times and dried glue buildup. Use only enough glue to get the job done.
After you’ve wiped away any stray glue streaks, make sure you put your glue away properly. Remove any excess glue stuck in the nozzle, which can dry and seal the bottle shut. You'll also want to store the glue in a cool, dry place that isn’t subject to extreme temperatures.
