One formula definitely does not fit all when it comes to good glue for plastic DIY projects. Adhesives are chemically designed to work with certain materials. Wood glue, for example, is great for carpentry but won’t be effective on metal. Even super glue—possibly your default option for just about anything—has its limits, as its active ingredient (cyanoacrylate) doesn’t adhere well to smooth surfaces.
We recommend the Pratley Powda Bond Adhesive Repair Kit as our best overall pick because of its powerful super glue and powder formula and compatibility with a wide variety of materials.
Trickier still, gluing plastic depends largely on the target material. A glue that works well to bond plastic to plastic may be a poor choice to adhere plastic to metal or wood. Most DIYers maintain a collection of adhesives to get the job done right the first time, so don’t get stuck using the wrong product. Read on to discover the best glues for plastic that we selected—some of which we even tested—and find out why the choices below rate as the top options for all your plastic bonding needs.

What to Consider When Choosing a Glue for Plastic
A good plastic adhesive should survive in certain conditions. When deciding which glue for plastic is best for your project, it is important to consider several factors first, including the type of glue, the compatible materials, the adhesive strength, and the durability. Here are some of the most common elements shoppers will want to keep in mind when choosing a glue for plastic.
Types of Glue for Plastic
Strong glues designed for plastic come in several different types, including cyanoacrylate (super glue), model cement, epoxy, and multipurpose.
Cyanoacrylate
While some adhesives rely on evaporation to form a bond between two objects, cyanoacrylate (commonly known as super glue) uses anionic polymerization to form a chemical bond when it comes in contact with hydroxyl ions in water.
This essentially means that super glue only requires water to bond to a substance. Since almost any surface has at least some moisture on it from humidity in the air, super glue can form a strong bond between virtually all surfaces. The one exception is hard, smooth plastics; for optimal results in projects like automotive body repairs, use sandpaper to scuff smooth plastic before applying super glue. Also, keep in mind that cyanoacrylate can discolor or degrade acrylics, so it wouldn’t be ideal for gluing plexiglass windows, for example.
Model Cement
Model cement relies on solvents like butanone, toluene, or dichloromethane to melt plastic on application as well as a filler, such as polystyrene, to then weld the plastics together. This method of joining materials makes model cement only effective on plastic. It cannot be used with metal, wood, ceramic, stone, or concrete. As the name implies, this adhesive is commonly used for joining plastic components while building models; it’s also used to connect ABS pipe together and in plumbing with PVC pipe.
Epoxy
Epoxy normally comes in two tubes with separate or connected plungers, depending on the brand. One tube is filled with a resin, the other with a hardener. When the two are pushed out of the tubes onto a surface and combine, they create a very strong, durable, and water-resistant adhesive. Epoxies are best for metal, ceramics, rubber, wood, and certain plastics.
While some epoxies form an incredibly strong bond in only 5 minutes, others can require more than 2 hours of clamping, 12 hours of drying time, and 1 to 2 days until they are fully cured. When used properly, epoxies are extremely versatile and can be seen in many industries, including electronics, medical devices, and aerospace; DIYers rely on waterproof epoxies for boat and dock repairs.
Multipurpose
Multipurpose glues—including carpenter’s glue, white glue, school glue, and wood glue—are intended for porous materials like wood, paper, cloth, pottery, and nonstructural wood bonds. They aren’t effective for nonporous materials like plastic and metal because polyvinyl acetate, the active ingredient, relies on evaporation and a porous surface to form a bond between two objects. Though great for everyday use, multipurpose glues may require clamping in place for up to an hour so water can evaporate from the glue, leaving the polyvinyl acetate behind to form a bond. Full curing takes between 18 and 24 hours.
Adhesive Strength
Plastics for glues can be used in automotive, electrical, crafting, school, or office tasks. Each glue has a different tensile strength depending on its specific use. Some options are capable of withstanding 2,000 to 5,020 PSI of pressure. However, small household glues like super glue may only be able to withstand over 1,000 PSI. Some options are also water-, weather-, temperature-, and solvent-resistant, which provides added durability when under pressure or around moving components.
Flexibility
Flexibility is an important factor in glues for plastics as the objects being repaired must move and bend once the glue has cured. These glues are used on automobiles, boats, aquariums, and more. They’re also used for crafts or office tasks, allowing objects to bend when under duress. Read the product manual of any item needing repair to ensure that the glue being used will provide the appropriate flexibility.
FAQs
For best results, it’s wise to fully understand how to properly use glues designed for bonding plastic. Find answers to some of the most common questions about these adhesives below.
Plastics are traditionally hard to glue since most have a nonporous surface that creates limited adhesion. Plastics typically come in categories 1, 2, 4, and 5, and category 1 is the hardest to glue. However, any glues that can adhere to polyethylene or polypropylene are ideal for most plastic varieties.
Soft and hard plastics can be glued together with the right product. The best option for soft and hard plastic gluing is the Loctite glue for plastic as it is capable of adhering to almost all plastic varieties and has a water-resistant, nonshrinking epoxy formula that dries clear.
Plastic glue is a broader category of glues that super glue (cyanoacrylate) belongs to because of its ability to bond with some plastics. Epoxies, model cement, and multipurpose glue (polyvinyl acetate) could also be considered plastic glue.
Super glue takes seconds to dry on plastic, but typical options may take up to 24 hours to fully cure. When applying glue on plastic in machinery or aquariums, users will want to be sure to let the glue set for the full curing time before any components begin to move to prevent malfunction or breakage.
According to the manufacturer, Gorilla Glue can work well with many plastic types, but it’s not recommended for use with polypropylene or polyethylene plastics, or with rubber that has a high oil or plasticizer content. The company does make specific products for these materials, however.
If you get plastic glue on your hands, soak them in warm water and massage the skin to try to remove the glue. If this fails, apply acetone (nail polish remover) to remove the glue, making sure to wash well after use and apply lotion, as acetone is drying to skin.
