What You'll Learn
Using glue to attach plastic to a mirror
When using glue to attach plastic to a mirror, it is important to select an appropriate adhesive to ensure a strong and long-lasting bond. The type of adhesive used will depend on the specific materials being bonded, the environment the bond will be subjected to, and the desired appearance of the final product.
One option for attaching plastic to a mirror is to use epoxy glue. Epoxy glues, such as Loctite Epoxy Gel, can create strong and impact-resistant bonds with various materials, including metal and many rigid plastics. This type of adhesive is suitable for outdoor and vertical applications, making it a good choice for attaching plastic to a mirror. However, it is important to note that epoxy glues may not be suitable for bonding directly to the reflective surface of the mirror, as they can cause delamination. Instead, epoxy glues are typically used for repairing mirror housings or backing materials.
Another option for attaching plastic to a mirror is to use a silicone adhesive. Silicone adhesives are known for their strength, elasticity, and excellent resistance to moisture and weathering. They can also be used as sealants, making them a versatile choice for bonding plastic to a mirror. Silicone adhesives are expected to last over 30 years in all weather conditions and can tolerate a wide temperature range. However, one drawback of silicone is that it can be messy in small applications and may require a greater degree of skill to apply neatly.
When working with any type of adhesive, it is important to follow safety precautions. Wear safety goggles and gloves to protect yourself from sharp edges and small pieces of the mirror or plastic. It is also crucial to work in a well-ventilated area, as some adhesives may have strong fumes. Always read the manufacturer's instructions for the specific adhesive you are using to ensure proper application and curing.
To attach plastic to a mirror using glue, start by cleaning and preparing the surfaces to be bonded. Ensure that the mirror and plastic are free of any dirt, grease, or debris that could interfere with the adhesive bond. Once the surfaces are prepared, apply the adhesive to the back of the mirror or the plastic, following the manufacturer's instructions for the correct amount and application method. Carefully bring the two surfaces together and apply pressure to ensure good contact. If necessary, use clamps or tape to hold the pieces in place while the adhesive cures. Finally, allow the adhesive to cure completely before handling or using the bonded assembly.

Preparing the surface for gluing
Clean the surfaces
Start by cleaning both the plastic and mirror surfaces with a suitable solvent. Isopropyl alcohol (rubbing alcohol) is recommended for cleaning the plastic, followed by a glass cleaner. Ensure that the mirror surface is also thoroughly cleaned and free of any dust, grease, or residue. This step is essential, as glue may not adhere properly to dirty surfaces, and contaminants can weaken the bond.
Dry the surfaces
After cleaning, make sure both surfaces are completely dry before proceeding. Use a lint-free cloth or air drying to remove any moisture or solvent residue. It is important to wait until the surfaces are entirely dry to touch.
Roughen the surfaces (optional)
Consider roughening the surfaces of the plastic and mirror slightly to create a better mechanical bond for the glue. This can be done by gently sanding or abrading the surfaces with fine-grit sandpaper. However, be cautious not to create visible scratches or damage the finish. This step may not be necessary for all types of adhesives, so refer to the instructions of your chosen glue.
Prepare the workspace
Ensure your workspace is clean and free of dust or debris that could contaminate the glue. It is advisable to work in a well-ventilated area to avoid inhaling any fumes from the adhesive. Additionally, gather all the necessary tools and materials, including the adhesive, gloves, safety goggles, and any clamps or supports needed to hold the pieces in place while the glue cures.
Choose the right adhesive
Select an adhesive suitable for bonding plastic to glass or mirrors. Some recommended options include Glue E6000, Loctite's rearview mirror adhesive, or a two-part epoxy specifically designed for this purpose. Consider the curing time, flexibility, and strength of the adhesive to determine which one best suits your project. Always read and follow the manufacturer's instructions for the chosen adhesive.
By carefully preparing the surfaces of the plastic and mirror through cleaning, drying, and optional roughening, you create the optimal conditions for gluing. Following these steps will help ensure a strong and long-lasting bond between the two materials.

Framing a mirror with plastic clips
Step 1: Measure the Mirror
Start by measuring the outside dimensions of your mirror. You will need these measurements to cut the framing material to the correct size. Make sure to measure accurately to ensure a precise fit.
Step 2: Choose Your Framing Material
You can use a variety of materials to frame your mirror, such as wood, plastic, or metal. Consider the style and decor of your space when choosing the material and colour of your frame.
Step 3: Cut the Framing Material
Using the measurements from Step 1, cut the framing material to size. For a neat finish, cut the corners of the framing material at a 45-degree angle so that they fit together to form the corners of the frame. You can use a mitre saw or a hand saw for this step, depending on your tools and expertise.
Step 4: Mark the Location of the Clips
Place the cut framing material against the mirror and use a pen or pencil to mark the locations of the plastic clips. This step is important to ensure that you avoid the clips when attaching the frame to the mirror.
Step 5: Attach the Frame
Now, you have a few options for attaching the frame:
- Glue: You can use glue or adhesive to attach the frame directly to the mirror. This method may require some trial and error as you need to ensure a secure bond without the glue affecting the mirror's surface.
- Hanging Frame: Alternatively, you can create a hanging frame by attaching sawtooth hangers to the back of the frame and screwing the frame directly above the mirror, allowing it to hang like a picture. This method avoids the plastic clips altogether.
- Washers: If you want to keep the plastic clips in place, consider using washers between the mirror and the frame. This method can provide a secure fit and a neat finish.
Tips and Tricks:
- When cutting and assembling the frame, take care to wear appropriate protective gear, such as safety goggles and gloves.
- Sand the framing material if necessary to ensure a smooth finish.
- If using glue, work in a well-ventilated area and follow the manufacturer's instructions for safe use.
- Consider adding a beveled edge to your mirror for an elegant touch.

Using a wetting agent to attach plastic to mirrors
When attaching plastic to mirrors, one of the challenges is ensuring that the mirroring chemicals flow evenly over the plastic surface without beading up. Water has a higher surface energy than plastic, so water molecules are more attracted to each other than to the plastic. This results in the water beading up and rolling off the plastic surface, preventing an even application of the mirroring chemicals.
To address this issue, a wetting agent can be used to lower the surface energy of the water, allowing it to flow more easily over the plastic surface. Wetting agents, also known as surfactants, reduce the surface tension of liquids, enabling them to spread out and make better contact with the surface to which they are applied.
In the context of mirroring plastics, a wetting agent can be applied to the plastic surface before immersing it in the mirroring chemicals. This helps break the surface tension of the water, allowing the chemicals to adhere evenly without beading up. The wetting agent lowers the surface energy of the water, making it more attracted to the plastic surface and enabling a more effective coating process.
It is important to select a suitable wetting agent that is compatible with the specific mirroring chemicals being used. Additionally, the plastic surface should be thoroughly cleaned with isopropyl alcohol (rubbing alcohol) and glass cleaner before applying the wetting agent to ensure optimal results.
By using a wetting agent, you can improve the adhesion and flow of the mirroring chemicals, resulting in a more uniform and effective attachment of plastic to mirrors. This technique can enhance the quality and appearance of the mirrored plastic surface.

Types of plastic that respond well to mirroring
Plastic mirrors are generally made by placing the plastic in a vacuum chamber and coating it with metal vapour. However, this may be challenging for DIY projects.
Acrylic mirror sheets are a type of plastic mirror that has gained popularity in recent years. They are made of a plastic polymer, allowing them to be customized to almost any size and shape. Acrylic mirrors are solid and durable yet lightweight, making them easy to manipulate and install. They are also impact-resistant and shatterproof, making them ideal for use in gyms, dance studios, martial arts schools, and malls. However, one drawback of acrylic mirrors is their tendency to absorb moisture, especially in damp or humid conditions, which can cause warping and distortion.
Another type of plastic that can be used for mirroring is PLA, which has been found to respond well to spray silver products. Epoxy resin, when used with a wetting agent and sensitizer, can also be mirrored using spray silver.
Overall, while glass mirrors may provide superior quality and precision of reflection, plastic mirrors, such as those made from acrylic or PLA, offer advantages in terms of customizability, weight, impact resistance, and ease of installation.
