When working on an upholstery project, one of the most crucial considerations is selecting the right glue. And because there are many types of glue out there, you have to know exactly what type you need for your project.
Whether you are a DIY enthusiast or a professional upholsterer, this article will help you learn more about some common types of upholstery glue and make an informed decision.
Advantages of Using Upholstery Glue
Glue is a must for upholstery projects. It creates strong bonds, ensures a flawless finish, provides durability, and offers versatile applications.
- Strong bonds: Certain types of adhesives work well with materials like foam, fabric, wood, leather, and vinyl. It ensures structural integrity and longevity.
- Time-saving solution: Glue saves time because it allows for quick application, compared to tacking or sewing. That’s why glue is a good choice for large-scale projects.
- Flexibility and durability: Glues that are specifically manufactured for upholstery projects remain flexible even after drying. It prevents damage or cracks over time.
- Professional finish: Glue offers invisible adhesion, and the outcome looks professional. Even if it is a DIY project, it will give a high-quality, factory-like appearance.
These benefits, however, depend on the correct application of the glue. Be sure to read and follow the guidelines that come with the product (More on that later).
Common Types of Glue Used in Upholstery projects
Several different types of glue are used for upholstery projects. They include spray adhesive, contact adhesive, hot glue, fabric glue, wood glue, low-melting-point glue sticks, and glue guns. You have to make a choice depending on the specific project you are going to work on.
Below, we will shed light on these glue types, their use cases, and the advantages and disadvantages of each type.
Spray Adhesive
Upholstery adhesive spray is popular, and the main reason for its popularity is its ease of use. It works well with lightweight materials, like fabric and foam. You have total control over its application, it dries quickly, and the bonds look seamless. Most large-scale upholstery projects heavily rely on this type of glue.
Spray adhesive is ideal for projects that require strong bonds and even glue distribution. It works best with some specific materials. They include foam, wood, lightweight fabrics, and padding layers. Upholstery spray glue is a commonly used vehicle upholstery glue.
While spray adhesive offers these advantages, there are still some disadvantages.
Pros and cons of using upholstery spray adhesive:

To get the best out of spray adhesive, you have to shake the canister well before application. When applying, hold the canister at a distance recommended in the user guide.
Contact Adhesive
Contact adhesive is ideal for heavy-duty upholstery projects that require strong, permanent bonds. If you are working with leather, dense fabrics, or vinyl, your project needs contact adhesive. It is a widely used glue for car upholstery.
This type of adhesive works very well with materials with non-porous surfaces, such as vinyl and leather. Contact adhesive is also a great choice when it comes to attaching metal or wooden furniture frames. You need contact adhesive for heavy-duty upholstery projects that require durable, permanent bonds.
Pros and cons of using contact adhesive for upholstery projects:
| Pros | Cons |

Apply contact adhesive on both surfaces, and consider using a roller for larger surfaces.
Hot Glue
Composed of thermoplastic polymers, hot glue is a type of adhesive that melts when exposed to heat. It dries and solidifies quickly upon cooling. The application of hot glue requires a glue gun, which helps apply the adhesive precisely.
Hot glue is suitable for attaching cording, gimp, trims, and braids. Before you staple or sew fabric edges, you can use hot glue to keep those edges in place. There is also specifically manufactured hot glue for fabric, which is very handy for small tears and minor upholstery repairs.

Fabric Glue
Fabric glue is a flexible, washable adhesive that basically serves as an alternative to sewing. The main ingredients of this glue are water-based polymers. Fabric glue dries by evaporation and forms a flexible bond. There is also spray adhesive for fabric.
It is the best glue for cloth to cloth, and is mostly used for fabric repairs like small holes and torn seams. You can use this glue for upholstery projects that require securing lightweight fabric layers while avoiding stiffness. It is suitable for projects where the fabric must retain its softness and drape.
Pros and cons of using fabric adhesives:
| Pros | Cons |
|---|---|

Allow cure times before you wash the fabrics. For delicate fabrics, run a small test before you use fabric glue for your project.
Wood Glue
Wood glue, which is typically polyvinyl acetate or aliphatic resin, is used for reinforcing or bonding the wooden parts of upholstery. It creates a strong and durable bond that can withstand pressure.
It is known for its high tensile strength and works better with porous wood.
You will need wood glue for repairing the wooden components of your upholstery. The components can also be hardwood, MDF, or plywood. Wood glue is often used along with screws or staples.
Pros and cons of using wood glue:
| Pros | Cons |
|---|---|

When bonding the components, clamp for the recommended time. Use a damp cloth to wipe out the excess.
Tips for Using Upholstery Glue Effectively
There are some general application techniques that can help you get the best out of upholstery glue. Keep the following tips in mind:
- Prepare the surface: Clean and dry the surface before applying the upholstery glue. Make sure there is no dust, dirt, or grease. If the surfaces are too smooth, abrade them for better adhesion.
- Apply the glue properly: Distribute the glue evenly, making sure the layer is consistent. Avoid dry spots and lumps. Do not apply excessively.
- Be careful about the drying and curing times: Read the user guidelines and allow the curing times after you’ve applied the glue. Rushing the process will compromise bond strength.
- Test before application: Before you apply the glue, test it on a small, inconspicuous area. Also, check for the compatibility and bond strength of the glue.
To know the best way to apply the glue, always read the user guide that comes with the product.
