Plexiglass, also known as acrylic, is a type of plastic material with a number of useful properties. It is lightweight, shatter-resistant, and has good optical clarity, making it a popular choice for applications such as windows, display cases, and signage.
Gluing plexiglass to wood can be a useful way to create custom structures or displays, or to repair or reinforce existing structures. In order to achieve a strong and long-lasting bond, it is important to choose the right adhesive and follow the proper steps for applying it. In this article, we will provide an overview of the materials and techniques needed to glue plexiglass to wood successfully. So, this project is all about gluing plexiglass to wood.
Choosing the Right Adhesive
There are several types of adhesives that can be used to bond plexiglass to wood. Some of the most common options include:
Epoxy
Epoxy is a strong and durable adhesive that is well-suited for bonding plexiglass to wood. It has excellent bonding strength and is resistant to water and chemicals. However, epoxy is not very flexible, so it may not be the best choice for applications where the bond will be subjected to movement or vibration.
Silicone
Clear silicone adhesives are also suitable for bonding plexiglass to wood. They have good bonding strength and are flexible, making them more suitable for applications where the bond may be subjected to movement. Silicone adhesives are also resistant to water and UV light, but they may not bond as well to certain materials as epoxy.
Pva Glue
PVA (polyvinyl acetate) glue, such as Weldbond, is another option for bonding plexiglass to wood. It is strong and flexible, and it is water-resistant and non-toxic.
When choosing an adhesive for bonding plexiglass to wood, it is important to consider the bonding strength, flexibility, and water resistance of the adhesive. Other factors to consider may include the drying time, ease of application, and cost.
Preparing the Surfaces
Properly preparing the surfaces of the plexiglass and wood is an important step in the process of gluing them together. This helps to ensure that the adhesive can create a strong and long-lasting bond.
Here are the steps for preparing the surfaces:
Sand the Surfaces
Sanding the surfaces of the plexiglass and wood will create a rough surface for the adhesive to grip onto. Use a fine-grit sandpaper (e.g. 120 grit) to gently scuff the surfaces of both the plexiglass and wood.
Clean the Surfaces
Remove any dust or debris from the sanded surfaces using a clean cloth or paper towel. Make sure the surfaces are completely clean and dry before proceeding to the next step.
Degrease the Surfaces
If the plexiglass or wood surfaces have any oils or grease on them, this can interfere with the adhesive’s ability to bond properly. To remove these contaminants, use a degreaser or rubbing alcohol to clean the surfaces. Wipe the surfaces with a clean cloth or paper towel to remove any residue.
By following these steps, you can ensure that the surfaces of the plexiglass and wood are clean and ready for bonding.
Applying the Adhesive
Once the surfaces of the plexiglass and wood have been prepared, it’s time to apply the adhesive. Here are some tips for applying the adhesive evenly and smoothly:
- Use a clean, dry surface: Make sure the surface you are working on is clean and dry, as any dust or debris can interfere with the bonding process.
- Follow the manufacturer’s instructions: Read the label on the adhesive carefully and follow the manufacturer’s instructions for use. This will ensure that you are using the adhesive properly and achieving the best results.
- Use the right amount of adhesive: Apply a thin, even layer of adhesive to the surface of the plexiglass. Do not use too much adhesive, as this can cause the bond to be weak or prone to failure.
- Spread the adhesive evenly: Use a flat tool, such as a palette knife or spatula, to spread the adhesive evenly across the surface of the plexiglass.
- Avoid air bubbles: Be careful to avoid creating air bubbles as you apply the adhesive. If you do create air bubbles, use a pin or needle to pop them.
Once you have applied the adhesive, it’s time to bond the plexiglass to the wood. Here are the steps to follow:
- Align the plexiglass and wood: Make sure the plexiglass and wood are properly aligned before bonding them together.
- Place the plexiglass on the wood: Carefully place the plexiglass onto the wood, making sure that it is seated evenly on the adhesive.
- Clamp the plexiglass and wood together: Use clamps or other suitable fasteners to hold the plexiglass and wood securely in place while the adhesive dries.
- Allow the adhesive to dry: Follow the manufacturer’s instructions for drying time. Be sure to allow the adhesive enough time to cure fully before removing the clamps or handling the bonded plexiglass and wood.
By following these steps, you can bond plexiglass to wood successfully and achieve a strong and long-lasting bond.
Finishing Touches
After bonding the plexiglass to the wood, there are a few finishing touches that you can take to ensure a strong and long-lasting bond. Here are some tips to follow:
Use Clamps or Other Fasteners
Clamping the plexiglass and wood together while the adhesive dries can help to ensure a strong bond. You can use clamps specifically designed for bonding acrylic, or you can use other types of fasteners, such as screws or brackets, to hold the plexiglass and wood in place.
Allow the Adhesive to Cure Fully
Be sure to follow the manufacturer’s instructions for drying time, and allow the adhesive enough time to cure fully before removing the clamps or handling the bonded plexiglass and wood.
Avoid Stressing the Bond
Avoid applying excessive force or stress to the bond, as this can weaken it. For example, if you are using the bonded plexiglass and wood for a display case or shelving unit, be sure to distribute the weight evenly to avoid stressing the bond.
In some cases, you may want to add additional support or reinforcement to the bond between the plexiglass and wood. Here are some optional steps you can take:
Use Fasteners
In addition to using clamps or other fasteners to hold the plexiglass and wood in place while the adhesive dries, you can also use fasteners, such as screws or brackets, to provide additional support and reinforcement to the bond.
Add Structural Support
If the bonded plexiglass and wood will be subjected to significant stress or load-bearing, you may want to add additional structural support to the bond. This could include using reinforced brackets or other types of support to distribute the load evenly and prevent the bond from failing.
By following these tips and taking the optional steps as needed, you can ensure a strong and long-lasting bond between plexiglass and wood.

Editor’s Note
There are a few options for adhesives that can be used to bond acrylic to timber. One option is to use a two-part epoxy glue, such as Araldite, which has strong bonding properties and is resistant to water and chemicals. However, epoxy is not flexible, so it may not be suitable for applications where the bond will be subjected to movement or vibration.
Another option is to use a clear silicone adhesive, which has good bonding strength and is flexible, making it more suitable for applications where the bond may be subjected to movement. Silicone adhesives can also be resistant to water and UV light, but they may not bond as well to certain materials as epoxy.
Weldbond is a PVA (polyvinyl acetate) based glue that is also suitable for bonding acrylic to timber. It is a strong and flexible adhesive, and it is water-resistant and non-toxic.
It is important to prepare the surfaces to be bonded by sanding or scuffing them to create a rough surface for the adhesive to grip onto. This will help to ensure a strong bond between the acrylic and the timber.
