Display cabinets are a great way to showcase collectibles, and Plexiglas is a popular material for constructing them. Plexiglas is a brand name for sheet acrylic, which is durable, shatterproof, lightweight, and easy to work with. When building a display cabinet, it's important to consider the design, cutting, and assembly process. During the assembly, the type of adhesive or mounting method plays a crucial role in ensuring the cabinet is safely and securely attached to the wall. This can be done using screws, plastic wall anchors, epoxy, or tape, depending on the wall material and the weight of the items being displayed.

What You'll Learn

Using plastic wall anchors
Plastic wall anchors are ideal for attaching items to drywall, especially when wood studs are unavailable. They are also suitable for thin walls where standard drywall anchors are too thick.
To use plastic wall anchors, you will need a drill, drill bits, a screwdriver, and a hammer.
First, create a pilot hole by tapping a nail into the drywall. The pilot hole should be smaller than the width of the anchor. You can also use a drill bit to create the hole, but be sure to consult the instructions on the drywall anchor package to select the correct size.
Next, place the anchor in the pilot hole and tap it into the wall until it is completely inserted. The anchor's plastic sleeve should have a flange that rests flat against the face of the drywall.
Then, place a Phillips or flat-head screwdriver in the notched head of the anchor and turn it clockwise. Apply firm, but not hard, pressure to draw the anchor into the drywall. Continue turning until the anchor is flush with the drywall, being careful not to twist too hard to avoid stripping the head.
Finally, add the provided screw to the drywall anchor. You can also use a wing-style anchor, but you will need to detach the bolt from the wings before sliding it through the hole in the item you are attaching. Turn the screw clockwise until the item is securely fastened, but be careful not to overtighten.

Gluing with epoxy or hot glue
When it comes to gluing plastic, it's important to first identify the type of plastic you're working with, as different plastics require different types of adhesives. For instance, plastics in categories 1, 2, 4, and 5 are very difficult to glue, and you'll need to look for an adhesive specifically designed for polyethylene or polypropylene. Category 3, PVC, is commonly used in plumbing, and can be glued using a two-part primer and PVC solvent cement. Category 6 plastics, on the other hand, are made of polystyrene, and can be bonded using poly cement, epoxy, or cyanoacrylate.
Now, if you're looking to attach plastic bars to a display cabinet, either epoxy or hot glue (such as the Infinity SuperTAC 500 Plastic Bonding Glue Sticks) can be used, depending on the type of plastic. Epoxy is a strong adhesive that can augment the structural strength of the plastic and provide good chemical resistance. It is created by mixing a hardener and a resin. However, it is important to note that some plastics, such as polyethylene and polypropylene, have very low surface energy, making it difficult for the epoxy to properly bond. In these cases, you would need an adhesive specifically designed for these plastics.
Hot glue, or hot-melt adhesives, also come in a variety of formulations, but not all of them are suitable for bonding plastics. However, there are some strong hot-melt adhesives designed specifically for bonding plastics, which could be a good option for attaching plastic bars to your display cabinet.
When using epoxy or hot glue, it's important to follow the instructions on the product carefully. Make sure the surfaces are clean and dry before applying the adhesive, and consider sanding the plastic surface if it is very smooth, as adhesives tend to bond better to rougher surfaces. Additionally, ensure that you are working in a well-ventilated area, as the fumes from some adhesives can be strong.
Keep in mind that attaching plastic bars to a display cabinet may also involve other considerations, such as the thickness of the cabinet walls, and whether you need to cut the bars to size. You may also want to explore other attachment methods, such as plastic anchors or screws, depending on the specific requirements of your project.

Attaching to thin wall material
Attaching items to thin wall material can be challenging as the wall may not be able to support the weight of the object or the force used to attach it. Here are some tips for attaching plastic bars to a display cabinet with thin walls:
Firstly, consider using an adhesive. Construction adhesive can be applied in zigzags or waves along the back of the plastic bar, ensuring coverage across the entire surface area. Press the plastic bar onto the wall firmly and allow the adhesive to dry. This method is quick and easy, but may not be suitable for heavier items or items that will undergo stress or tension, as the adhesive bond may not be strong enough to withstand significant force.
Another option is to use plastic wall anchors. First, drill a hole into the wall at the desired location. The hole should be slightly larger than the width of the anchor. Then, screw the screw into the wall anchor and gently tap the screw head with a hammer to prevent bending. Finally, screw the plastic bar into the wall anchor. This method provides a stronger hold than adhesive, but it does require drilling into the wall, which may not be possible or desirable in some cases.
If you are concerned about the weight of the plastic bars or the strength of the attachment, consider using a combination of adhesive and wall anchors for added security. Additionally, be sure to clean the wall thoroughly before attaching anything to it, as dirt, grease, or other substances can interfere with the adhesion process.

Using drywall screws
Drywall screws are commonly used to hang cabinets, but they are not ideal for this purpose as they are brittle and can snap under too much torque. They are also typically too short to properly secure a cabinet, and are not designed for hardwood materials.
However, if you are set on using drywall screws to attach plastic bars to a display cabinet, here is a step-by-step guide:
First, use a stud finder to locate the studs in the wall. You will need to drill your screws into these studs to ensure the cabinet is properly supported. Mark the locations of the studs, and use a level to draw a straight line across the wall to indicate the bottom length of the cabinets.
Next, attach the plastic bars to the display cabinet. You can do this by drilling holes into the cabinet and the bars, and then using screws to attach the bars. Make sure the bars are securely attached to the cabinet before proceeding.
Now, you can attach the cabinet to the wall. Drill pilot holes through the cabinet, centering the holes over the studs. Use long drywall screws, at least 2.5 inches in length, and drive them through the holes and into the studs. Make sure the screws are tight and that the cabinet is securely attached to the wall.
Finally, you can remove any ledger screws or holding screws you used to support the cabinet during installation. If there are any gaps between the cabinet and the wall, you can fill them with a strip of moulding. Cut the moulding to the appropriate length, stain and finish it to match the cabinet, and then nail it in place.
While drywall screws can be used to hang cabinets, it is important to note that they may not provide sufficient support, especially for heavy cabinets or those made of hardwood. For a more secure installation, it is recommended to use cabinet screws or other specialized hardware.

Drilling the right-sized hole
Choose the Right Drill Bit
Firstly, you need to select an appropriate drill bit size. Measure the diameter of the screws or bolts you will use and choose a drill bit that is slightly smaller. This will ensure a snug fit for your plastic bars. The drill bit size should be compatible with the screws you intend to use.
Create a Template
To ensure consistent placement and spacing of the holes, consider creating a template or jig. This tool helps you measure and mark the exact spots where you need to drill. You can make your own template at home using cardboard, paperboard, or MDF board. A template will help you achieve precise measurements and save time.
Mark the Spots
Before drilling, mark the spots where you will create the holes. You can use an awl to create small indentations on the surface of the cabinet. This will prevent the drill bit from wandering off course. Alternatively, you can make light pencil marks to indicate the centre points.
Apply Masking Tape
To prevent splintering around the drilled holes, apply masking tape or painter's tape over the marked spots. Painter's tape is preferable if you want to avoid leaving any residue on the surface. This step will help you achieve a clean finish.
Drill the Holes
Now, it's time to drill! Start with a smaller drill bit to create starter holes, and then switch to a larger drill bit that matches the size of your screws. Drill slowly and carefully to ensure accuracy. Remember to wear appropriate safety gear, including eye protection, when operating the drill.
By following these steps, you will be able to drill the right-sized holes for attaching plastic bars to your display cabinet. Take your time, and ensure that your measurements are accurate for a professional and secure finish.
