Stapling leather to plastic can be challenging due to the risk of the plastic fracturing or the stapler slipping. While it is possible to use a staple gun, it is not recommended for hard plastics. Instead, consider using an electric or pneumatic staple gun, which can pierce through hard plastic with greater force and less manual labour. Alternatively, you can use adhesive glue, such as epoxy, contact cement, polyurethane, or silicone adhesive, to create a strong bond between the leather and plastic. Proper surface preparation and cleaning are crucial for effective adhesion, and sanding the plastic surface can enhance the adhesive bond.

What You'll Learn

Use an electric stapler for hard plastic
When stapling leather to hard plastic, an electric stapler is a good option. Electric staplers are commonly used for upholstery, and can successfully be used on plastic. They are more cost-effective than pneumatic staple guns, which are more powerful but also more expensive.
If you are using an electric stapler to attach leather to hard plastic, you will need to apply more manual pressure to get the staples to insert correctly. This is because smooth plastic surfaces can cause the stapler to slip, and hard plastic can fracture under pressure. This makes it difficult to pierce, and the staples may not insert correctly without sufficient force.
To avoid this issue, you could opt for a pneumatic staple gun, which provides more power to pierce through the dense plastic surface. Pneumatic staple guns do not require as much manual pressure, but they are more costly.
Another option is to use an air stapler, which is likely the only tool with enough power to penetrate hard plastic. However, purchasing a tool like this may not be cost-effective, and it may be cheaper to have an upholsterer do the work for you.
If you are set on using an electric stapler, be sure to use one that shoots 3/16 x 9/16" staples, as these are the most common and effective for this purpose.

Pneumatic staple guns pierce plastic
Staple guns are commonly used for DIY projects and upholstery. They are used to drive heavy metal staples into various materials, including wood, plastic, masonry, insulation, upholstery, and leather.
Pneumatic staple guns are one of the three types of staple guns, distinguished by their power source. They are powered by compressed air and are more expensive than electric staple guns. Pneumatic staple guns are quite forceful and can be dangerous if not handled carefully. They are capable of piercing hard plastic due to their power and are the best option for this purpose. However, they might cost more than alternative methods such as using adhesive glue or screws.
Electric staple guns are another option for stapling plastic. They are cheaper than pneumatic staple guns but require more manual pressure to insert staples correctly. They can be used successfully on plastic, but the process may be more labor-intensive and time-consuming.
Manual staple guns are not powerful enough to penetrate hard plastic. Therefore, pneumatic or electric staple guns are the preferred choices for stapling leather to plastic.
It is important to consult the operations manual before using any staple gun on plastic to ensure it is suitable for that purpose. Additionally, always prioritize safety when operating a pneumatic staple gun due to its forcefulness.

Manual labour is required for staples to be inserted correctly
Stapling leather to plastic is not a straightforward task. Hard plastic, in particular, can be difficult to pierce and tends to fracture when under pressure. Smooth plastic surfaces can also cause the staple gun to slip, which may lead to injury. Therefore, manual labour is required for staples to be inserted correctly.
To staple leather to plastic, a pneumatic staple gun is the best option. This type of staple gun provides enough power to pierce through the dense plastic surface. It is also easy to use, requiring minimal effort from the user. However, pneumatic staple guns tend to be more expensive than other options. If you are looking for a cheaper alternative, an electric staple gun can also work on plastic. However, it requires more manual pressure from the user to insert the staples correctly.
Another important factor to consider is the type of staple used. Staples that are 3/16 x 9/16" are the most common size for stapling plastic.
If you are unable to obtain a pneumatic or electric staple gun, there are other methods for attaching leather to plastic. Adhesive glue, for example, is an affordable and easily attainable alternative. Cyanoacrylate, also known as Super Glue, can be used on any type of plastic. Epoxy adhesives are also a popular choice for bonding leather to plastic due to their exceptional strength and versatility. Other options include contact cement, polyurethane adhesives, and silicone adhesives.
Before gluing leather to plastic, it is important to properly prepare the surfaces to ensure a strong and long-lasting bond. This includes thoroughly cleaning the surfaces and lightly sanding the plastic to create a rough texture that the adhesive can effectively grip.

Use glue as an alternative method
If you are looking to attach leather to plastic, glue is a great alternative method to stapling. This method is affordable, straightforward, and does not require any specialist tools.
Firstly, it is important to determine the type of plastic and leather you are working with, as this will impact the type of glue you can use. For example, nylon or PVC plastics may not bond well with certain types of glue.
Once you have identified your materials, you can select the most suitable adhesive. Cyanoacrylate, also known as Super Glue, is a versatile option that can be used on a variety of materials. Another option is contact cement, which requires you to scuff up the plastic surface to promote adhesion and then apply cement to both the plastic and the leather. After applying the cement, let it dry for about 10 minutes before sticking the materials together and applying pressure to bond them.
If you are working with smooth plastic, it is important to note that this surface can cause a staple gun to slip, leading to potential injury. Hard plastics are also difficult to pierce and can fracture when under pressure. Therefore, using glue can be a safer and more effective alternative.
Using glue instead of staples can be a simple and cost-effective solution for attaching leather to plastic. It does not require any specialized tools or technical precision, making it a great option for DIY projects.

Epoxy adhesives offer strong adhesion
While staple guns are a popular tool for many DIY projects, they are not typically used on plastic. This is because smooth plastic surfaces can cause the staple gun to slip, leading to injury. Additionally, hard plastic tends to fracture under pressure, making it difficult to pierce.
If you are set on using a staple gun, a pneumatic staple gun is the best option as it provides enough power to pierce through hard plastic. An electric staple gun is a more affordable but more labour-intensive alternative.
However, if you are looking for a safer, more cost-effective, and straightforward method, adhesive glue is a great option. Epoxy adhesives, in particular, offer strong adhesion and are ideal for bonding dissimilar materials such as plastics to metals. They are the strongest type of glue you can get, with some epoxies reaching a strength of up to 30 MPa, sufficient to replace welding.
Epoxy adhesives also have good chemical resistance, meaning they won't break down when exposed to chemicals. They are not susceptible to fatigue, which is when an adhesive weakens under repeated stress. However, epoxies are usually brittle, so they are not suitable for bonding materials that vibrate or move. Additionally, epoxies require extensive surface preparation to achieve a strong bond, and they may not be suitable for filling large voids due to their exothermic properties.
Overall, if you are looking for a strong and durable bond between leather and plastic, epoxy adhesives are a great option. Just be sure to follow the instructions carefully and allow for the appropriate cure time.
