When it comes to gluing rubber to rubber or a variety of diverse substrates, the project’s success depends on selecting the optimal adhesive for the job. Manufacturers offer a range of glue types for specific types of rubber, so choosing the best adhesive for rubber can be challenging.

The best options provide a strong, durable bond that’s permanent when it’s fully cured. In some cases, weather resistance and waterproofing are desired. For other jobs, the flexibility or elasticity of the bond is important. The difficulty of bonding two smooth and nonporous substrates may present an additional problem.

Read on to discover products that offer some of the best glue for rubber adhesion to meet the challenges of many DIY projects.

The Best Glues for Rubber Options

Types of Glue for Rubber 

Manufacturers offer several types of glue that work well with specific types of rubber. These include one-part glues such as super glue that’s also called cyanoacrylate adhesive (CA) and silicone-based glue. Alternatively, some rubber adhesion projects require two-part adhesives that require mixing for activation. These include epoxy resin and structural adhesive glues.

Super Glue

Super glue is an acrylic resin and a viable choice as an all-purpose glue for rubber. Its primary adhesive ingredient is cyanoacrylate. This ingredient is an acrylic monomer that requires moisture for curing.

In only a few minutes, cyanoacrylate begins to set up, forming a strong and rigid bond. While the quick setup time facilitates swift completion of assembly and repair jobs, it limits a user’s opportunities for adjusting or repositioning surfaces. Therefore, it’s important to work fast when using super glue.

Upon curing, cyanoacrylate transforms into a plastic state. Allow 24 hours for most super glue products to fully cure.

Epoxy Resin Glue

An epoxy resin glue consists of two parts: a resin and a hardener. Users mix the two parts together in a 1:1 ratio immediately before applying the adhesive to a substrate.

For storage, the resin and the hardener are housed in two separate containers. A double syringe system is often used for storing, mixing, and applying epoxy resin. With the double syringe, these steps are neat and simplified for the user.

Epoxy resin forms a waterproof and weatherproof bond. Additionally, it’s useful for filling gaps. Therefore, it’s useful for outdoor applications as well as indoor repairs around the home.

Two-Part Acrylic Glue

Certain rubber substrates are known to pose problems when users try to adhere them. These include polyethylene, polypropylene, polytetrafluoroethylene (PTFE), and ethylene propylene diene monomer (EPDM) rubbers. With slippery, smooth, and nonporous surfaces, it may be difficult for glues to form bonds on these materials. Two-part structural acrylics can work well for these difficult gluing jobs.

For activation to occur, two-part acrylic glues require mixing. The user purchases these adhesives in two separate parts and mixes them immediately before applying the adhesive. Since they are stored separately, two-part adhesives are more stable than the premixed types. Therefore, they demonstrate a longer shelf life, and users may count on their efficacy after storing for extended periods.

Silicone-Based Glue 

Silicone rubber is exceptionally resistant to high heat. For this reason, it’s used in making ovenware and cookware. Additionally, manufacturers use silicone rubber in the production of gaskets, O-rings, medical devices, and prosthetics.

The best glue for silicone rubber is a silicone-based adhesive. This type of glue creates bonds that are flexible (not rigid) after curing. Additionally, they resist damage from high temperatures and exposure to chemicals and water.

Silicone rubber is slippery in nature. If an adhesive bond does not hold, the user can apply a primer to increase the surface friction before applying the silicone adhesive.

What to Consider When Choosing Glue for Rubber

When choosing an adhesive product for rubber, the first step is to identify the type of rubber to be glued. From there, shoppers can determine the best type of glue, keeping in mind various factors such as weather resistance, flexibility, set time, cure time, and more. These features are described below.

Type of Rubber

Before selecting the best glue for rubber to rubber or rubber to other substrates, it’s important to identify the type of rubber to be glued. The following list details types of rubber and their uses.

  • Nitrile is a commonly used oil-resistant synthetic rubber. It’s used to make conveyor belts, hoses, O-rings, gaskets, and cable jacketing.
  • Polyurethane is a synthetic rubber that is commonly used for molds and modeling.
  • Natural rubber is sourced from the Pará rubber tree native to Brazil but now cultivated in many Asian countries. It’s used in gaskets, seals, mountings, and carpet backing.
  • Butyl rubber is flexible and bendable. For this reason, it’s used in applications where flexibility is required. Butyl rubber products include innertubes, seals, stoppers, linings, and valve seating.
    Silicone rubber is exceptionally resistant to high heat. Manufacturers use it to make bakeware, cookware, O-rings, gaskets, medical devices, and prosthetics.
  • Rubber made from ethylene propylene diene monomer (EPDM) is used in automotive hoses and seals. It’s a difficult substrate for gluing, requiring a two-part acrylic glue for successful adhesion.

Application and Bond Strength 

Shoppers may consider their rubber-adhesion needs when selecting the best glue for rubber. For example, some jobs require gap-filling and sealing while other jobs demand a superior bonding strength for load bearing. Taking these factors into consideration, users may select from a range of rubber adhesives.

Flexibility and elasticity are additional factors for consideration. If the object to be glued requires flexibility for its functional purpose, then the adhesive must yield a flexible bond when fully cured.

The ease of application is an additional consideration when selecting a rubber adhesive. Shoppers might search for glue application systems that prevent drips and spills. Of course, the size of the job is a determining factor, as some glue applicators yield only limited amounts of glue while others expel a bead of adhesive suitable for covering large surface areas.

Curing Time

Crafters and DIYers often need to distinguish between setting time and curing time. When glue is applied to substrates for adhesion, the set time indicates the period in which the glue is soft enough to allow repositioning or adjustment of the surfaces. In other words, the set time is the period from initial application until the glue hardens. Once it hardens, the surfaces can no longer be repositioned.

Super glue yields a fast set time. This means users have minimal time to realign the surfaces before the glue begins to harden. Users might read package labels to discern set times for various types of adhesives. These times may range from a few minutes up to 1 hour.

When the glue starts to harden and set, that’s only the beginning part of the curing time. Generally, adhesives for rubber typically require 24 hours for curing, which is when the product is chemically cured and offers the full properties of the product. DIYers should refrain from using or manipulating glued objects until the full curing time has elapsed.

Additional Features

For adhesive jobs where weather resistance is a factor in the project’s ultimate success, shoppers might search for durable waterproof glues. This is frequently a primary consideration, as rubber is often used in hoses, gaskets, seals, and linings that must be waterproof to function properly. The adhesive for an assembly or repair job is most effective when it is as waterproof as the rubber material.

Often, manufacturers package their adhesives in containers that facilitate ease of use. Shoppers might look for convenient containers that prevent drips and spills. Additionally, double-syringe systems simplify the mixing and application steps for two-part adhesives.

Depending on the particular job at hand, users may want to consider the viscosity of an adhesive. Low-viscosity glues flow easily, displaying a watery consistency. High-viscosity glues are thicker and therefore flow more slowly.

Tips for Using Glue for Rubber 

For best results in gluing rubber, it’s important to identify the exact type of rubber. Based on the type of rubber, DIYers can research the best glue for the adhesion job.

Once the user acquires the most appropriate glue for the job, the next step is to prepare the substrates. After preparation, DIYers can simply follow the manufacturer’s directions and then allow time for the glue to cure.

  • Use a type of glue recommended for the specific type of rubber.
  • Purchase a small amount and try out the glue in a small application before using it in a bigger adhesion job.
  • Prep the rubber surface with isopropanol solvent, which is in rubbing alcohol. (Acetone may be too harsh.)
  • Some slippery rubber surfaces may require primer before gluing.
  • Some rubber substrates may require sanding or scratching to increase the surface friction for bonding.
  • For safety reasons, work in a well-ventilated area.
  • Cover the work surface with a drop cloth or paper in case of drips or spills.
  • Follow the manufacturer’s instructions regarding application of the adhesive.
  • Note the setup time to facilitate repositioning the adhered substrates before the glue hardens.
  • Allow the full curing time before manipulating the glued objects.


Crafters and DIY enthusiasts may need to glue rubber substrates in the course of pursuing their favorite hobbies. Additionally, anyone who makes home or auto repairs may run into the occasional need to glue rubber objects to various surfaces. The most advantageous approach for these jobs is to identify the specific type of rubber and to research the best rubber glue for the job. Read on for frequently asked questions and answers regarding rubber materials and the best choices in rubber glue.

Q. How do I find out if a material is PVC or rubber?

Rubber demonstrates a greater level of elasticity than polyvinyl chloride (PVC) plastic, so a rubber object can stretch and then contract back into its original shape.

Q. Can I use hot glue on rubber?

Hot glue is not the best adhesive for rubber; it will not stick to many smooth and slippery surfaces (such as silicone rubber). Instead, a cyanoacrylate adhesive is used.

Q. How do I glue latex?

Rubber cement works well with latex. It’s available at most stationery and office supply stores. Special latex glue is a good choice, as is super glue (with cyanoacrylate).
