What You'll Learn
Sand the surfaces to improve adhesion
Sanding the surfaces of the plastic and leather will improve adhesion by creating a rougher surface for the glue to bind to. This process is sometimes referred to as "scuffing up" or creating a "scratch" on the surface. It is important to note that you should only sand the surface of the plastic if it is not made from nylon or PVC.
To sand the surfaces, you can use sandpaper or a sanding block. The grit of the sandpaper you use will depend on the smoothness or roughness of the surface you are starting with. If the surface is already relatively rough, a finer grit sandpaper can be used. If the surface is smooth, a coarser grit sandpaper will be more effective.
When sanding, use gentle, even pressure and move the sandpaper in a consistent direction. Avoid applying too much pressure or sanding too quickly, as this can create grooves or scratches on the surface. It is important to sand both the plastic and leather surfaces evenly to ensure a strong adhesion.
Once you have finished sanding, it is important to wipe down the surfaces with a damp cloth to remove any dust or debris. Allow the surfaces to air dry before applying any glue or adhesive.
By sanding the surfaces of the plastic and leather, you will create a better bond for the glue to adhere to, resulting in a stronger and more durable adhesion.

Clean the surfaces with a damp cloth
To stick plastic to leather, it is important to clean the surfaces with a damp cloth. This is a crucial step in the gluing process, as it ensures that the adhesive will bond effectively to both the plastic and leather surfaces.
Firstly, use a clean cloth or brush to wipe down both the plastic and leather surfaces. This initial wipe-down helps to remove any dust, dirt, or debris present on the surfaces. It is important to ensure that the surfaces are free of any such particles, as they can weaken the bond between the adhesive and the materials.
If necessary, you can also use a mild soap solution to clean the surfaces. This is especially useful if there are any oily residues present. After using the soap solution, make sure to dry the surfaces thoroughly.
Once the surfaces are clean and dry, you may want to consider roughening them using sandpaper. Creating a textured surface through this process can improve the adhesion of the glue and increase the bond strength. However, this step is optional and may not be required for all projects.
After roughening the surfaces, it is crucial to clean them again with a damp cloth. This step ensures the removal of any debris or dust created during the roughening process. Again, the presence of such particles can hinder the adhesion of the glue, so it is important to wipe down the surfaces thoroughly.
By following these steps and cleaning the surfaces with a damp cloth, you will ensure that the plastic and leather surfaces are properly prepared for gluing. This will help create a strong and lasting bond between the two materials.

Apply a thin layer of glue to both surfaces
When gluing plastic to leather, it is important to use the right adhesive to ensure a strong and lasting bond. One of the most popular adhesives for gluing plastic to leather is contact cement, such as Weldwood. Other popular glue options include Barge All-Purpose Cement Quart, Gorilla Super Glue Gel, and Loctite Adhesive.
Before applying the adhesive, it is important to prepare the surfaces of both the plastic and the leather. This involves cleaning both surfaces with a damp cloth to remove any dust, dirt, oils, or debris. If necessary, you can use a mild soap solution to clean the surfaces, but be sure to dry them thoroughly.
To further enhance the adhesion of the glue, you can create a textured surface on both the plastic and the leather using sandpaper. This will allow the adhesive to grip the surfaces more effectively and result in a stronger bond. Just be sure to wipe away any debris or dust after using the sandpaper.
Once the surfaces are clean and prepared, you can begin to apply a thin layer of glue to both the plastic and the leather. You can use a brush or any applicator of your choice to evenly spread the adhesive. Be sure to follow the manufacturer's instructions for the specific adhesive you are using to ensure proper application.
After applying the glue, you will need to wait for it to dry. The drying time will vary depending on the type of adhesive used, but it is generally around 10-15 minutes. During this time, the adhesive will become tacky and ready for bonding.
Once the glue is dry to touch, you can carefully align the plastic and leather surfaces, applying firm pressure to ensure maximum surface contact. This helps create a uniform bond and eliminates any air pockets. You can use a ruler or similar object to apply even pressure along the entire surface.
