Gluing an acrylic display case requires careful preparation and the right adhesive to achieve a strong, clear bond. Here's a step-by-step guide:
1. Choose the Right Adhesive
- Solvent Cement: This is the most common and effective adhesive for acrylic. It works by slightly melting the acrylic surfaces and fusing them together, creating a very strong and nearly invisible bond. Brands like Weld-On are popular.
- Acrylic Glue: Some adhesives are specifically formulated for acrylic, offering good bonding strength and clarity.
Important: Do not use regular super glue (cyanoacrylate). It can craze or cloud the acrylic, ruining the appearance.
2. Prepare the Surfaces
- Clean: Thoroughly clean all surfaces to be glued with a dedicated acrylic cleaner or a mild soap and water solution. Ensure there are no oils, dust, or fingerprints. Dry completely with a lint-free cloth.
- Sand (Optional): Lightly sanding the edges to be bonded can improve adhesion. Use fine-grit sandpaper (400 grit or higher) to roughen the surface slightly. Remember to clean the sanding dust before proceeding.
3. Application
- Capillary Action: Solvent cement is very thin and works best by capillary action.
- Dry Fit: Assemble the display case pieces and use tape to hold them in place. Ensure a tight fit between the pieces.
- Apply Cement: Use a syringe, applicator bottle with a fine tip, or a small brush to apply the solvent cement along the joint. The cement will flow into the gap.
- Direct Application: For certain designs, you may directly apply a small amount of the solvent cement to one surface before joining the pieces.
4. Curing
- Secure: Keep the pieces clamped or taped together until the adhesive has fully cured, usually at least 24 hours. Refer to the adhesive manufacturer's instructions for specific curing times.
- Ventilation: Work in a well-ventilated area as solvent cement can release fumes.
5. Clean Up
- Avoid Excessive Glue: Try to avoid excessive glue, as it can mar the appearance.
- Remove Excess: If there's excess adhesive, carefully scrape it away with a sharp blade after it's completely cured.
- Polish: For a smooth finish, you can polish the edges with acrylic polish.
