Gluing plastic to wood can be challenging because plastics don't typically adhere easily to other substances. The type of plastic you are using will determine the best type of glue to use. For example, ABS and Nylon plastics are good for gluing, while Polypropylene and Polyethylene are more difficult to bond. To get plastic to adhere to wood, you will need to use a heavy-duty super glue, like Loctite or Gorilla Glue, or an epoxy. Before gluing, you should sand the plastic with high-grit sandpaper to help the glue stick better and clean the wooden surface with a damp cloth to remove dust and dirt.

What You'll Learn
Sand the plastic surface lightly to increase its surface area
When adhering plastic to wood, it is important to sand the plastic surface lightly. This process increases the overall surface area of the plastic, allowing it to bond more effectively with the adhesive. To do this, use a square of high-grit sandpaper and gently go over the broadest area of the plastic piece with a few smooth, delicate strokes. Be careful not to rough up the plastic too much, as you want to create a porous surface without causing any damage.
The goal is to create a slightly rough texture on the plastic surface, which will provide a better grip for the glue. By increasing the surface area, you are providing more points of contact for the adhesive to grip onto, resulting in a stronger and more durable bond. This technique is especially useful when working with plastics, as they can be challenging to adhere to other materials.
It is important to note that the type of sandpaper you use can make a difference. High-grit sandpaper, often denoted as fine-grit sandpaper, is ideal for this task as it will create a finer scratch pattern on the plastic surface. This type of sandpaper is designed to smooth out surfaces and create a more refined finish, which is perfect for preparing the plastic for gluing.
Additionally, when sanding, it is recommended to use light pressure and work in the direction of the grain (if there is one) to achieve the best results. This will help ensure that you do not damage the plastic while still achieving the desired level of roughness to enhance the adhesion process.
Overall, lightly sanding the plastic surface is a crucial step in preparing the material for adhesion. By increasing the surface area, you are optimizing the conditions for a strong and long-lasting bond between the plastic and the wood.

Use heavy-duty super glue, like Loctite or Gorilla glue
Gluing plastic to wood can be tricky, especially since plastics don't stick to other substances very easily. To adhere plastic to wood, you can use a heavy-duty super glue, like Loctite or Gorilla Glue. Loctite Plastics Bonding System, for example, creates a powerful bond with just one drop. It is water-resistant, sets in seconds, and dries clear. Loctite Epoxy Five-Minute Instant Mix is another option that works on a variety of materials, including wood and plastic, and is easy to use with its self-mixing syringe.
Gorilla Glue is another heavy-duty adhesive that will give you more lasting results than ordinary types of glue. It is a two-part epoxy glue that comes in a dual-syringe form and uses a combined plunger to push the resin and hardener out through the same point. It sets in 5 minutes and takes 24 hours to fully cure to a clear, spotless finish.
Before applying the glue, sand the plastic with high-grit sandpaper to help the glue stick better. Go over the broadest area of the plastic piece with light, smooth, and delicate strokes to avoid roughing up the plastic too much. Sanding the plastic will make it more porous and increase its overall surface area, allowing it to bond to the wood more easily. You can also clean the wooden piece with a damp cloth to remove dust and dirt that might interfere with the hold.
After sanding and cleaning, apply the glue to both surfaces. Squeeze the tube slowly to control the flow of the glue, using only as much as needed. Depending on the size and shape of the surface, you may want to use stripes, dots, or swirls. Press the two surfaces together and let the glue set for a couple of hours.

Epoxy is a good adhesive for plastics like ABS and Nylon
Gluing plastic to wood can be tricky, especially if you want a permanent bond. While super glues like Loctite and Gorilla Glue can be used, epoxy is a much better adhesive for plastics like ABS and Nylon. Epoxy resin adhesive is a two-component adhesive that works on the basis of a chemical reaction between a resin and a hardener. This creates extremely strong bonds and can be used to bond different materials such as metal and wood.
Epoxy adhesives are particularly suitable for bonding large areas that have to withstand high loads. They are also ideal for repairing ABS plastic. There are several epoxy adhesives on the market, including EP30-4, EP51M, and EP65HT-1, which offer varying properties such as non-yellowing, high tensile strength, and tensile modulus.
When working with epoxy resin, it is important to take safety precautions as it can be harmful to your skin and eyes. Make sure to wear long-sleeved clothing, safety glasses, nitrile gloves, and a respirator. Additionally, ensure that the work area is well-ventilated and follow the manufacturer's instructions.
Before applying epoxy or any other adhesive, it is important to prepare the surfaces. Sand the plastic surface lightly with high-grit sandpaper to increase its porosity and surface area, allowing it to bond more easily with the wood. Clean the wooden piece with a damp cloth to remove any dust or dirt that might interfere with the adhesion.
Overall, epoxy is a superior adhesive for bonding plastics like ABS and Nylon to wood due to its strong bonding properties and versatility. With the right preparation and safety measures, you can achieve a permanent and sturdy bond between these two materials.
