How to Glue Perspex to Wood

Perspex, also known by the brand name Plexiglas or generically as acrylic, is a versatile plastic material that can be used for a variety of applications from custom aquariums to decorative accents. With the right adhesive and preparation, Perspex can be securely bonded to wood to create beautiful and functional projects. In this guide, we’ll walk through the steps for how to glue perspex to wood.

Key Takeaways:

• Choose compatible adhesives like acrylic, epoxy, polyurethane or cyanoacrylate glues
• Lightly sand then clean surfaces with isopropyl alcohol
• Apply a thin, even layer of adhesive and clamp materials while curing
• Let adhesive fully cure; up to 48 hours for acrylics
• For clear bonds, use optical adhesives and vertical curing

4 Trustworthy Steps for How to Glue Perspex to Wood

Here are the steps you need to follow for how to glue perspex to wood:

Step 1: Choosing the Right Adhesive

The key to creating a strong, long-lasting bond between Perspex and wood is using the right adhesive. Here are some of the best options:

• Acrylic adhesives – Designed specifically for bonding acrylic to various surfaces, these adhesives provide optical clarity and flexibility. Brands like Acrifix and Evostik provide exceptional results.
• Epoxy – A two-part adhesive that cures to a rigid, durable bond. Epoxy has high shear and tensile strength perfect for load-bearing projects.
• Polyurethane – Flexible and waterproof, polyurethane glues like Gorilla Glue expand to fill gaps while bonding. Great for outdoor applications.
• Cyanoacrylate – Commonly called “super glue”, cyanoacrylates provide quick bonds for small-scale projects. They lack long-term durability.

Consider the type of project when selecting an adhesive. Acrylic adhesives excel when optical clarity is key, while epoxy suits heavy-duty structural applications.

Step 2: Preparing the Surfaces

Proper surface preparation is vital for acrylic adhesives to bond correctly. Follow these steps:

• Lightly sand the Perspex and wood with 120-150 grit sandpaper to create a rough surface texture.
• Clean thoroughly with isopropyl alcohol to remove any oils, dust, or debris.
• Avoid over-handling the surfaces after cleaning to prevent transferring dirt or oils from your hands.

Some adhesives like epoxy also require “keying” the surfaces, which produces an intricate pattern for the glue to grip. Lightly score the Perspex and wood in a crosshatch pattern with an X-Acto knife before sanding and cleaning.

Step 3: Applying the Adhesive

With clean surfaces prepped, it’s time to apply the adhesive:

1. Follow the adhesive manufacturer’s instructions precisely. Do not improvise.
2. Apply a thin, even layer on both surfaces. Too much adhesive makes the bond weaker.
3. The adhesive must cover the entire bond area. If possible, apply to the smaller piece for more control.
4. Avoid air bubbles by gently pressing materials together, forcing bubbles to the edges.
5. Use clamps, tape or small nails to hold the Perspex and wood securely as the adhesive sets. Do not move or stress the materials until fully cured.
6. Acrylic adhesives require a long cure time, up to 48 hours. Be patient for maximum strength.

Step 4: Achieving an Optical Bond

For clear applications where the adhesive will be visible, like a display case, extra steps ensure optical clarity:

• Select the clearest drying adhesive like Acrifix 1R0115.
• Apply the thinnest adhesive layer possible, ideally 0.05 – 0.1mm thick.
• For bubble-free application, use adhesive tape or LM glazing film to gently lower Perspex onto the wood from above.
• Cure the project vertically with Perspex side down to prevent drips marring the surface.

With care, optical bonds between Perspex and wood can be strikingly clear and beautiful.

5 Tips for Successfully Gluing Perspex to Wood

Follow these tips to achieve success gluing Perspex to wood:

1. Test adhesive compatibility and application on scrap pieces first
2. Avoid over-clamping, which can squeeze adhesive away from the bond area
3. Let adhesive fully cure before stressing the bond through movement or weight
4. Consider reinforcing structural joints with discreet brackets or corner braces
5. For outdoors, use marine-grade adhesives and seal project edges against moisture
