What You Need to Know About Gluing Rubber to Plastic
Can You Glue Rubber to Plastic?
You can glue rubber to plastic. It might be challenging because the two surfaces have different properties, but as long as you’re using the right kind of glue, you will have no problem achieving a strong bond.
It’s very important to find a glue that will bond effectively with the rubber material as well as the kind of plastic surface you’re gluing it to without causing any damage to either of them.
To determine the kind of plastic surface you have, you can check the recycling symbol that is embossed or printed somewhere on the plastic item.
What Are the Best Kind of Glue to Use on Rubber and Plastic?
There are different kinds of glues that can be used on rubber or plastic separately, but few of them can be used on both
Let’s take a look at the best kinds of glue to use on rubber and plastic:
This kind of glue is commercially known as Super Glue or Crazy Glue.
It’s mainly made from a chemical compound called cyanoacrylate which gives it the ability to form extremely strong bonds with various kinds of surfaces including plastic, rubber, metal, and glass.
However, keep in mind that the surface this glue is applied to needs to have some degree of moisture in order for the glue to react and bond.
This kind of glue is commercially known as Gorilla Glue.
It’s mainly made from a chemical compound called polyurethane which allows it to form one of the strongest and longest-lasting bonds with various kinds of surfaces including plastic, rubber, metal, glass, stone, wood, and ceramic.
It’s also water-resistant and can withstand a significant amount of pressure.
This kind of glue is made from two components, resin and a hardening substance, which typically come in separate containers.
The resin and the hardening substance need to be combined before applying them to the surface in order for the glue to bond effectively.
It might take longer to completely dry and cure compared to other kinds of glue, however, it will create an extremely strong bond with different kinds of surfaces including plastic and rubber.
The bond created can also resist chemical influences and withstand a significant amount of pressure.

How to Glue Rubber to Plastic?
To achieve a strong bond when gluing rubber to plastic, you need to make sure that you’re using the right kind of glue and that the surface you’re applying the glue on is prepared to take on the bond.
Here is a step by step guide you can follow to properly glue rubber to plastic:
Prepare the surfaces for bonding.
You need to clean the rubber and plastic surface from any contaminants like dirt or grease using a cloth soaked in rubbing alcohol, then leave both surfaces to air dry.
That is because these contaminants can interfere with the glue’s ability to bond with the surface which will result in a weaker bond.
If the plastic surface you’re applying the glue on is too smooth, the glue might not be able to bond properly. So, it might also be a good idea to roughen the surface a little using fine-grid sandpaper before applying the glue.
Apply the glue to both surfaces.
When applying the glue, make sure you have enough to evenly cover the entire surface. It’s also recommended to apply the glue in a thin layer to help it dry faster.
You can use a paintbrush to apply the glue so you can have better control over where and how much of the glue is applied. You can also use a toothpick or a Q-tip to apply the glue in any hard-to-reach areas.
Press the surfaces together and make adjustments before the glue starts setting.
After applying the glue, you need to hold the two surfaces in place until the glue sets.
You’ll have at least a minute or two to make any final adjustments or to reposition the surfaces before the glue starts to set
Leave the surfaces to dry
Try not to move the surfaces during the drying process otherwise, the bond will fail and will need to re-apply the glue.
You can use any type of easy-to-remove adhesive tape or weight clamps to hold the surfaces together until the glue is dried and cured completely.
Frequently Asked Questions
How Fast Does Glue to Dry When Applied on Plastic?
Glue can take about 10-20 minutes to dry when applied to plastic. However, it takes up to 24 hours to cure fully so you can use the surface. The speed of the drying process depends on factors like the kind of glue used, the amount of glue applied, and the temperature of the room you’re working in.
How to Remove Glue from a Plastic or Plastic Surface?
To remove the glue from a plastic surface, you can use a solvent like acetone. It will help soften the dried glue and make it much easier to scrape off a surface. However, it’s recommended to test the solvent on a small area of the surface first to ensure it won’t cause any damage or discoloration.
