Bonding acrylic to acrylic requires a specific type of adhesive to create a strong, clear, and durable joint. Unlike many other materials, acrylic can be tricky; using the wrong glue can lead to cloudy seams, weak bonds, or even cracking the plastic itself. The ideal adhesive will either chemically weld the pieces into one solid piece of plastic or form a powerful, invisible bond that holds up over time.
Whether you’re building a display case, repairing a picture frame, or working on a DIY craft project, selecting the right product is crucial for a professional-looking and long-lasting result. From specialized solvent cements to versatile super glues, this roundup covers the top-performing options to ensure your acrylic projects are a success.

It sets rapidly in less than 60 seconds to create a high-strength bond between non-porous materials. The thicker formula is a key benefit, as it provides a slightly longer setting time to allow for better positioning.
This solvent-free, water-based glue uses advanced cyanoacrylate technology for a safer user experience. The high viscosity (HV) formula is excellent at filling gaps up to 0.25mm wide between materials, which can be crucial for achieving a strong bond on surfaces that are not perfectly mated. This makes it a robust and reliable choice for various bonding tasks.
SCIGRIP 10315 Acrylic Cement
SCIGRIP 10315 is another professional-grade solvent cement specifically designed for bonding acrylic plastics. Like the Weld-On product, it creates a chemical weld rather than just a surface bond, resulting in joints that are extremely strong and often as durable as the acrylic itself. This is the type of adhesive used in industrial and commercial acrylic fabrication.
It is ideal for creating clear, bubble-free seams in acrylic displays, models, and structures. For the best results, it should be used with a syringe applicator for precise control. While it requires careful handling and good ventilation, its performance for acrylic-to-acrylic bonding is considered top-tier by professionals and serious hobbyists alike.
Buying Guide: What to Look For in the Best Adhesives for Bonding Acrylic to Acrylic
When I need to glue acrylic to acrylic, my first thought isn’t just about grabbing the strongest glue I can find. It’s about finding the right type of adhesive that will actually work with the material. Acrylic is a type of plastic, and many common adhesives can actually damage it, causing it to crack or craze, which looks like a bunch of tiny, ugly stress cracks. The goal is an invisible, strong bond that looks like one solid piece.
The most important concept to understand is the difference between a mechanical bond and a solvent weld. A mechanical bond, like what you get from an epoxy or super glue, works by sticking to the surface of the acrylic. It can be strong, but it often leaves a visible glue line. A solvent weld, however, is the gold standard for acrylic. These adhesives don’t just stick the pieces together; they temporarily soften the plastic, allowing the acrylic molecules from both pieces to intermingle. As the solvent evaporates, the two pieces essentially fuse into one. This creates the strongest and clearest bond possible.
For this kind of project, I always look for adhesives specifically labeled for acrylic or polystyrene. The main types are solvent cements and specialized acrylic glues. Solvent cements, like those containing methylene chloride, are fantastic for capillary action. This means you can hold the two pieces together and apply the cement to the seam; it gets pulled in by capillary action, creating a seamless weld. They are perfect for tight-fitting joints. For filling small gaps, a water-thin cement is my go-to. If I have a slightly larger gap to fill, I might use a thicker, gel-like cement that doesn’t run as much.
Beyond the type, I consider the set time and the application. Fast-setting cements are great for small projects, but they give me less time to adjust the alignment. Slow-set cements are better for large or complex assemblies. I also think about safety. Many of these solvents have strong fumes and can be harmful, so I always work in a very well-ventilated area, ideally with a respirator mask, and wear nitrile gloves to protect my skin.
Finally, the application method matters. Many solvent cements come in a bottle with a fine needle applicator, which gives me pinpoint control. For larger surfaces, I might use a special applicator bottle designed for capillary action. By thinking about the bond type, the product’s formulation, and my own safety, I can choose the perfect adhesive from a list of the best adhesives for bonding acrylic to acrylic surfaces and get a professional-looking result every time.
FAQ
Can I use super glue or epoxy to bond acrylic?
You can, but I generally do not recommend it for a clean, professional finish. Super glue (cyanoacrylate) and most epoxies create a mechanical bond that sits on the surface. This bond can be brittle and may not withstand stress well. More importantly, it often leaves a visible, cloudy glue line. For the strongest, clearest bond that makes two pieces look like one, a solvent-based acrylic cement is far superior.
Why did my acrylic crack or turn white after gluing?
This is a common problem called “crazing,” and it usually happens for one of two reasons. First, you might have used the wrong type of adhesive. Adhesives that are not formulated for acrylic, or those that are too aggressive, can introduce stress and cause these tiny micro-fractures. Second, applying too much adhesive or forcing the joint can put excessive stress on the plastic, leading to cracking. Always use a cement designed for acrylic and apply it sparingly.
How long does it take for acrylic adhesive to fully cure?
This depends entirely on the product. A water-thin cement can set up in a minute or two and handle light handling, but it can take 24 to 48 hours to reach its full strength. Thicker gel cements take longer to set initially. While the bond might feel strong after a few hours, I always wait a full 24-48 hours before subjecting the project to any significant stress or pressure to ensure the solvent has completely evaporated and the weld is at maximum strength.
What is the best way to apply adhesive for an invisible seam?
For an invisible seam, the capillary action method is my preferred technique. I start by ensuring the edges I’m joining are smooth and fit together tightly. I then hold or clamp the two acrylic pieces together in their final position. Next, I use a bottle with a fine needle applicator to run a tiny bead of a water-thin cement along the top of the seam. The liquid is instantly drawn into the joint by capillary action, welding the pieces together from the inside out without a messy glue line.
Are there any safety precautions I should take?
Yes, this is very important. The solvents in acrylic cements are potent. I always work in a well-ventilated area, like a garage with the door open or outdoors. I wear nitrile gloves to protect my hands and use safety glasses to protect my eyes from splashes. A respirator mask rated for organic vapors is also a good idea to avoid inhaling the fumes. Always read the safety instructions on the product label before you begin. Following these steps is crucial for a successful project when using the best adhesives for bonding acrylic to acrylic surfaces.
