Stapling upholstery to plastic can be a tricky task. Hard plastics tend to fracture under pressure, which makes them difficult to pierce. While manual staple guns are not powerful enough to penetrate hard plastic, pneumatic staple guns are the best option for stapling into plastic. They are commonly more expensive than electric staple guns, which are a viable second option. Electric staple guns require more manual pressure to insert staples correctly. Alternative methods of fastening upholstery to plastic include using adhesive glue or screws.

What You'll Learn

Use a pneumatic staple gun for best results
If you're looking to achieve the best results when stapling upholstery to plastic, a pneumatic staple gun is the recommended tool for the job. This is because stapling into plastic, especially hard plastic, can be a tricky task. Hard plastic tends to fracture under pressure, which makes it difficult to pierce.
Pneumatic staple guns provide enough power to pierce through dense plastic surfaces thoroughly. They are generally more expensive than electric staple guns, but they are worth the investment if you are working with plastic. Pneumatic staple guns do not require much effort from the user, even when working with challenging surfaces like plastic.
On the other hand, electric staple guns are a more affordable option, and they can also be used on plastic. However, they require more manual pressure from the user to insert the staples correctly. If you are using an electric staple gun, be sure to use enough force to penetrate the plastic surface. It is important to note that manual staple guns are typically not powerful enough to penetrate hard plastic.
When choosing a pneumatic staple gun, look for one that accepts "series 71" staples in various leg lengths. These staples are available in stainless steel, which is essential for automotive and boat work. You can also use a brand like Arrow, but ensure that you can find all the required sizes in stainless steel.
Additionally, consider the size of the staples you will need for your project. For example, 1/8" staples are commonly used for door panels, but they can be challenging to find. 5/32" staples are also an option, but be mindful of the risk of them shooting through your panel. Always prioritize safety when operating power tools, and follow the instructions provided by the manufacturer.

Electric staple guns are a viable, cheaper option
When choosing an electric staple gun, consider the DeWalt Heavy-Duty Electric 5-in-1 Multi-Tacker, which is durable and efficient. Another option is the Porter-Cable US58 3/8" Crown Fine-Wire Stapler, which is light and powerful enough to countersink staples into oak furniture.
It is important to note that electric staple guns come in two types: plug-in and battery-powered. Plug-in models use electricity to fire staples, while battery-powered options offer more convenience and mobility when moving from job to job.
Additionally, consider the staple size when selecting an electric staple gun. Common gauge sizes for upholstery range from 18 to 22, with 22-gauge staples being the most common for this purpose.
By choosing an electric staple gun and selecting the appropriate staple size, you can effectively and affordably staple upholstery to plastic.

Manual staple guns are not powerful enough
Manual staple guns are a versatile and portable tool, suitable for a wide range of tasks. They are simple to use and affordable, making them a popular choice for many. However, they may not be powerful enough for certain applications, especially when dealing with dense or hard materials.
When it comes to stapling upholstery to plastic, the effectiveness of a manual staple gun will depend on the type of plastic and the thickness of the material. Manual staple guns may struggle to penetrate hard plastic and could require more force than the user can physically exert. This is because hard materials, such as certain plastics, metals, or hardwoods, demand a higher level of force to drive the staple in.
In such cases, an electric or pneumatic staple gun might be a better option. Electric staple guns can provide more power and efficiency, making them suitable for stapling through hard plastic. They are commonly used for stapling through materials such as hard plastic and are available in various brands.
Pneumatic staple guns, on the other hand, use compressed air to drive staples into materials. They are often used by professionals and are ideal for stapling through hard surfaces. For example, a pneumatic gun was used to reupholster a boat, where stainless steel staples were required to withstand saltwater exposure.
While manual staple guns offer convenience and simplicity, they may not be powerful enough for certain applications. For stapling upholstery to hard plastic, an electric or pneumatic staple gun could be a more effective choice, ensuring a secure fastening without the risk of misfires or inadequate penetration.

Adhesive glue is an affordable, alternative method
Spray adhesives, for example, work well with foam, wood, and fabric. They come in a variety of strengths, so it is important to understand the requirements of your project. Camie 513 Fast Tack Upholstery Adhesive, for instance, is perfect for working with foams and fabrics. It has a low VOC and a fast tack for quick bonding. ES60 EverStrong Adhesive is another good spray adhesive option, which also has the added benefit of being water-resistant.
Hot glue is another option for gluing upholstery to plastic. Infinity Bond Crystal Clear Glue Sticks can be used with fabric, foam, wood, paper, and more. They can be used in both low-temperature and high-temperature glue guns. The low temperature is great for fabrics and foam, while the high temperature can be used with wood and plastic. When selecting a hot glue gun, opt for one with high-power wattage and maneuverability. The Ad Tech PRO 200 Glue Gun, for example, is a good choice for heavy-duty work and has a four-finger trigger for added comfort during extended use.
Tuskbond also offers a range of upholstery adhesives. The HT150 is a multipurpose adhesive that dries to leave a high-tack film, suitable for bonding most fibrous materials, fabrics, insulation, and polythene foam to a variety of substrates. The HS350 is a fast-drying spray adhesive that is free from chlorinated solvents and is designed to provide fast, accurate, and ergonomic application. It is suitable for bonding a wide variety of substrates, including thin and thick fabric, Hessian, felt, foam, wood, plastic, and EPS.
When using adhesive glue, it is important to prepare the surfaces being glued. Ensure that the plastic surfaces are clean and scuffed to create a better bond. Applying a light coat of adhesive to the plastic in advance as a primer can also improve adhesion.
