How to bond acrylic?

Know More About Acrylic

When you use acrylic sheet, you may encounter a situation where you want to glue the acrylic together. Maybe it is wood? Could it be metal? It may also be that several acrylic boxes are glued to each other. During this process, I think you may have some doubts, such as what glue to choose, such as how to operate, then in response to these questions, I wrote this blog hoping to help you.

Bond acrylic to wood

Yes, acrylic can of course be glued to wood. We often encounter such situations in our lives. For example, when installing acrylic windows, windows do not only refer to household doors and windows but are more likely to be outdoor ones such as shed windows, boat windows, etc., so of course, they will touch wood.

How can I glue acrylic and wood together? Here we provide two methods.

Use a drill.

This method is actually very easy to understand. It’s like hitting a nail on the wood, but the nail passes through the acrylic.

First of all, we need to put the acrylic on the wood first and find the most suitable fixed position you think;

Then choose a suitable drill bit. Note that it must be a suitable drill bit for plastic products. Drill holes for both acrylic and wood. Be patient and cautious during the drilling process. Pressure must be uniform when applying pressure. Do not allow the acrylic to hit Hole and overheating, causing the acrylic to crack;

Use wood screws to screw the acrylic onto the wood until the screw head is flush with the surface. You must also remember to tighten it. Do not use excessive force, otherwise, the acrylic will still be at risk of cracking.

Use epoxy glue

The reason for using epoxy resin is that it does not require a chemical reaction to bond acrylic and wood together.

First, use sandpaper to polish the wood. At the same time, clean the acrylic surface to make it clean, then apply a thin layer of epoxy resin glue, clamp the material together, and wait for the glue to completely solidify.

Bond acrylic to metal

Adhesive acrylic to metal, although this kind of scene is actually relatively rare, it is not completely absent. For example, some metal product manufacturers often use acrylic as the background board to display metal samples, so it is necessary to glue the two Together.

Epoxy resin glue.

We can still use epoxy glue, but this time it is a two-part epoxy. The fully cured two-part epoxy will have excellent hardness and provide a tough protective coating with good heat resistance.

When gluing acrylic to metal, both materials should be roughened in the area to be bonded so that the glue has good adhesion. Acrylic can be treated the same as wood with medium-grain sandpaper, and steel wool or files can be used on metal.

After applying the glue, wait for the glue to cure completely.

HY-303 special metal glue.

However, for some metals, the bonding strength of epoxy resin type glue is not up to the requirement, and the curing time is also very long. In the above situation, it is recommended to use instantaneous type HY-303 special metal glue for bonding.

The first step is to do a good job of surface treatment. Use dry cotton cloth or sandpaper to remove dust, oil stains, rust, etc. on the adhesive surface. Use a detergent when necessary, and the sanding should not be too rough and dry. If alkaline substances remain, curing will be accelerated; if acid substances remain, curing will be slowed down.

Apply glue. When the shape and material of the adhered object are the same, apply glue on any side; if the shape and material are not the same, apply glue on the side of the bonding surface, or the side with a smaller area, or the surface with slow curing speed, or Difficult to penetrate the surface.

After applying the glue, align the position and overlap it, and it can’t be moved. Otherwise, the bonding strength will be affected. Press to keep the adherend in close contact, and then wait patiently for the glue to completely solidify.

Bond acrylic to plastic

The connection between acrylic and plastic should be the most widely seen in our lives. For example, in handwork, how to make an acrylic box? Then you need to bond all the acrylic sheets together.

Gluing acrylic resin to acrylic resin or other plastic materials is relatively simple because the material is the same, it will be relatively easier when you choose the adhesive, but please remember to read the instructions before proceeding.

Where there is almost no stress at the joint, such as in signage applications, adhesive tape can be used to glue the plastic together. Because of the lightweight of acrylic and many other sheet-like plastics, you can even use double-sided tape, although this connection is unlikely to survive long periods or where moisture is present.

To achieve a stronger connection, acrylic cement, and other plastic safety adhesives can be used. Whenever you glue acrylic, this is the key to removing contaminants such as grease and dust. If left, they may destroy the strength of the glue, so consider using a plastic cleaner to clean the material thoroughly.

Once again, strictly follow the manufacturer’s instructions on the adhesive and make sure that the glue is placed within the recommended time frame.

Bond acrylic to glass

The bonding of acrylic and glass is also very common. After all, the glass itself is very similar to acrylic, but acrylic is lighter. Therefore, acrylic has an advantage when weight and ease of handling need to be considered. Acrylic bonded glass often appears in the case of building aquariums or installing some acrylic partitions in existing aquariums.

No matter what the situation is, the first step is still cleaning. You must remove all dust, dirt, and other dirty materials to ensure that the acrylic and glass are clean. If you need to use a cleaning agent, please read the instructions carefully to ensure that the cleaning agent can be used with acrylic. Some cleaning agents can damage acrylic.

When choosing glue, you can use epoxy glue and adhesives suitable for use with plastics. Standard silicone can also be used, but it cannot be stored for a long time, especially in a high-humidity environment.

After applying the glue, wait patiently for the glue to solidify.


Yes, almost all manual work is difficult but difficult is also very fun. It just requires you to pay some patience. The process of pasting acrylic is not complicated, but you still need to be careful and pay attention to safety.
