1. Prepare the Surface of Both Parts

Rubbing alcohol or acetone is usually enough to clean and degrease the surface of your pieces before gluing them. Make sure you remove any dirt, oil, dust, rust, or other contaminants that could interfere with the adhesion of the rubber glue.

2. Determine the Right Adhesive for Your Project

There are several types of rubber adhesives available in stores; epoxy-based adhesives are a popular choice but polyurethane-based products may also be suitable. Make sure you read the instructions and warnings of the product before using it.

3. Apply Glue to Both Surfaces

Using a brush or an applicator, spread a thin layer of adhesive onto both surfaces where they will join together. Too much glue may cause it to ooze out from between your pieces when curing and can affect the adhesion process.

4. Assemble Your Parts

Put the two rubber objects together; use clamps or other tools to hold them in place while the adhesive dries. Be careful not to move them around too much or apply too much pressure as this could interfere with how well the rubber bond holds up over time.

5. Allow the Glue to Cure

Depending on the type of adhesive, it may take anywhere from a few minutes to several hours for the bond to set. Refer to the product instructions or label for curing time and temperature requirements.

6. Test Your Bond

After allowing enough time for the glue to dry, test your bond by carefully tugging on each part. If it holds strong then congratulations! You’ve successfully glued your rubber pieces together.

Here’s a table summarizing the key steps for gluing rubber objects together:

Step Description
1. Prepare the Surface Clean and degrease the surfaces with rubbing alcohol or acetone to ensure good adhesion

6 Different Types of Rubber and the Glues Used for Them

Understanding the different types of rubber and how to use them can be challenging. To help you out, we’ve put together a list of 6 types of rubber, with some tips on how to glue rubber to rubber.

1. Natural Rubber

Natural rubber is harvested from trees. Being harvested from trees make it strong, waterproof, and flexible. It also has excellent shock absorbency.

For gluing natural rubber to other materials or itself, a cyanoacrylate adhesive should be used as regular glues may not create a secure bond. It is often used in the following:

  • Tires
  • Seals
  • Hoses

2. Neoprene Rubber

Neoprene is similar to natural rubber but offers better chemical resistance and does not harden due to age. For gluing neoprene rubber to itself or other materials, a cyanoacrylate adhesive or contact cement works best. It is used for:

  • Seals
  • Gaskets
  • Insulation
  • Electrical components

3. Silicone Rubber

Silicone rubber has excellent heat resistance, UV radiation protection, and electrical insulation properties. To successfully glue silicone to itself or something else (such as metal) an epoxy adhesive should be used. It is often used in automotive applications such as:

  • Sealants
  • Hoses
  • Tubing
  • Weatherstripping

4. SBR Rubber

SBR stands for styrene-butadiene rubber and is similar to natural rubber but with improved abrasion-resistance properties due to its slightly lower flexibility. It can be glued with a cyanoacrylate adhesive or contact cement. It is often used for:

  • Industrial seals
  • Hoses

5. Butyl Rubber

Butyl rubber is very resistant to chemicals, ozone, UV radiation, and air pollutants. To glue butyl rubber to itself or other materials epoxy should be used. It is popular for automotive applications such as:

  • Inner tubes
  • Tire sidewalls
  • Gaskets

6. Nitrile Rubber

Also known as Buna-N, nitrile rubber is a synthetic rubber. It offers excellent abrasion resistance and good protection against oils, greases, and fuels. So an oil-resistant epoxy or cyanoacrylate adhesive should be used to glue it to itself or other materials. It is most often used in:

  • Fuel hoses
  • Gaskets

By understanding the different types of rubbers available, you’ll have a better idea of which type will work best for your project and how to securely glue it.

FAQS

1. Is rubber glue waterproof?

Rubber glue is also called rubber cement. When it dries it is waterproof and flexible. It can be used on surfaces including rubber, glass, leather, and ceramics.

2. Is rubber glue flammable?

Yes, rubber glue is flammable and it is not allowed in checked baggage or carry-on.

3. How long should I wait before applying pressure to the rubber?

Once you have applied the adhesive, you should wait at least 8 hours before applying pressure to the rubber. The adhesive needs time to dry fully and create a strong bond between the two pieces.

Depending on the type of adhesive you have used, it can take up to 24 hours for the bond to fully cure and be ready for use.

4. How should I prepare the rubber before gluing?

Make sure both surfaces of the rubber are clean and free of any dirt, dust, or debris. Then use soap and water to ensure the surface is clean before applying adhesive. If the rubber is in two pieces, you can use sandpaper to gently roughen up the surface of each piece.

5. What type of adhesive should I use to glue rubber to rubber?

The best type of adhesive to use for gluing rubber to rubber is a rubber-based adhesive. Some examples of rubber-based adhesives include silicone adhesive/sealant, neoprene adhesive, or EPDM adhesive.
