Attaching plastic to fabric can be done in several ways, depending on the materials used and the conditions to which the final product will be subjected. One common method is to use an adhesive, such as glue or spray adhesive. When selecting an adhesive, it is important to ensure that it is compatible with both fabric and plastic and to consider the flexibility of the adhesive to prevent cracking. The fabric and plastic surfaces should be clean and dry before applying the adhesive, and the plastic can be roughened with sandpaper to improve adhesion. Another method for attaching plastic to fabric is to use Velcro, with the soft loop side of the Velcro on the fabric and the rough/stiff side on the plastic to avoid snagging.

Roughen the plastic with sandpaper to improve adhesion
When gluing fabric to plastic, adhesion can be improved by roughening the plastic surface with sandpaper. This process helps create a stronger bond between the two materials. Here are some detailed steps and tips to guide you through the process:
Firstly, it is important to select the appropriate sandpaper grit for effective roughening without causing damage to the plastic. A grit coarser than 180 should be avoided as it may cut into the plastic and create deeper scratches that are harder to smooth out. Starting with 180-grit sandpaper is recommended to initially cut down any texture on the plastic surface. Subsequently, a finer grit sandpaper, such as 320-grit, can be used to achieve a smoother finish.
When sanding, always work in straight lines, making slight angles with each swipe. Avoid sanding in circles, especially if you are sanding by hand, as this can create scratches that are more challenging to remove. If using a power sander, the angle at which you hold the tool is not as crucial.
Wetsanding is another technique that can be employed. Start with 200-grit sandpaper to remove the majority of the texture, and then switch to 400-grit wetsanding to achieve a smoother finish. Always check the sandpaper frequently to ensure that it is not becoming clogged with primer or debris, as this can inadvertently create scratches on the plastic surface.
After roughening the plastic with sandpaper, it is essential to clean the surface to remove any dust or debris generated during the sanding process. Once the surface is prepared, you can proceed with the gluing process, choosing a suitable adhesive specifically formulated for bonding fabric to plastic.
By following these steps, you can effectively roughen the plastic with sandpaper, improving adhesion and creating a stronger bond when attaching fabric to plastic.

Use a flexible adhesive to prevent cracking
When gluing plastic to fabric, it's important to use a flexible adhesive to prevent cracking. A flexible adhesive will move with the fabric without cracking, ensuring a strong and long-lasting bond.
There are several types of adhesives that can be used for gluing fabric to plastic, including fabric glue, contact adhesives, and spray adhesives. However, not all adhesives are created equal, and some may become brittle and crack over time. To prevent this, it's important to choose a flexible adhesive specifically designed for use with plastic and fabric.
One option is to use a product like Loctite Vinyl, Fabric & Plastic Flexible Adhesive. This adhesive is designed to create a flexible bond that won't break down, making it ideal for gluing fabric to plastic. It's also waterproof and dries clear, so it won't leave any unsightly residue.

Apply masking tape to create a clean seam
When gluing plastic to fabric, you can use masking tape to create a clean seam. This is especially useful when repairing rips or tears of any size. Here's a step-by-step guide on how to apply masking tape to create a clean seam:
- Prepare the surfaces: Ensure that the fabric and plastic are clean and dry. If needed, roughen the plastic with sandpaper to improve adhesion.
- Apply masking tape: Put masking tape around the edge of the tear. This will create a clean seam and provide a neat finish.
- Insert a patch (optional): For larger tears, reinforce the area by inserting a cloth or fibreglass patch under the tear.
- Apply glue: Apply a small amount of glue to the edges of the rip or tear. Choose a glue that is compatible with both fabric and plastic and follow the manufacturer's instructions.
- Secure with masking tape: Press the edges of the fabric and plastic together and use masking tape to hold them in place while the glue dries.
- Remove excess adhesive: If you notice any excess wet adhesive, clean it up immediately with a damp cloth or acetone. Be careful, as acetone can damage some materials.
- Let it dry: Leave the glue to dry completely before using the item.
In addition to gluing, seam tape can also be used to create a clean seam and add water resistance or structural integrity to the fabric. Seam tape typically has a heat-activated adhesive on one side and a waterproof membrane on the other. It is commonly used for coated waterproof fabrics. When applying seam tape, follow these steps:
- Prepare the seam: Trim any excess seam allowance to provide more area for the tape to adhere to.
- Cut the tape: Cut a piece of tape slightly longer than the seam. The adhesive side of the tape will be placed against the seam.
- Apply heat: Place the tape centred on the seam, adhesive side down. Use a household iron to heat the tape, activating the adhesive. Cover the tape with baking paper or thin cotton fabric to protect the surrounding fabric from direct heat.
- Check adhesion: After heating, lift the iron to check if the glue has melted and the tape is in place. If not, apply heat for a little longer or adjust the heat setting.
- Secure the entire seam: Move along the tape, lifting the iron between sections. Once the whole seam is done, go over it again to ensure it is secure.
- Avoid removal: Once the tape is applied, do not try to remove it as it may damage the fabric.

Use a soft, clear adhesive like Shoo-Goo
When gluing plastic to fabric, it is important to select the right adhesive. The best glue for fabric and plastic is one that is specially formulated for those materials. A specially formulated glue will create a stronger, longer-lasting bond than a standard adhesive. It is also important to consider the flexibility of the glue, as you will want to avoid glues that may become brittle and crack when the materials move.
One option for a soft, clear adhesive is Shoo-Goo. To use this product, you will want to cut your fabric to closely match the shape of the plastic, leaving about 1/2 to 1/4 inch to wrap around the "backside" of the plastic. Put some dabs of Shoo-Goo on the inside of the plastic (the part that won't be seen) and loosely wrap the cloth around to the other side. It is important to note that Shoo-Goo works best when it is allowed to dry completely, so be sure not to pull too hard on the fabric during the wrapping process.
If you are gluing a tear or rip in a piece of fabric, there are a few additional steps you can take to ensure a smooth repair. First, reinforce the area by inserting a cloth or fibreglass patch under the tear. Then, apply masking tape around the edge of the tear to create a clean seam. Apply glue to the edges of the rip, press the edges together, and hold them in place with masking tape while the glue dries. Once the glue is dry, remove the tape and carefully cut away any excess glue with a sharp blade.
When working with any adhesive, it is important to follow the manufacturer's directions and take the necessary safety precautions. Work in a well-ventilated space and wear gloves to protect your hands. It is also a good idea to test the adhesive on a small area of the fabric first to ensure that it will not discolour or bleed through.
