How To Glue Two Pieces Of Perspex® Cast Acrylic Together
If you’ve never worked with Perspex® cast acrylic before, you should know that the glue used to join two pieces of Perspex® cast acrylic together is very different to your multi-purpose household glue. Unlike typical household glue, Perspex® cast acrylic glue (more accurately referred to as cement) works by bonding the particles of each edge together. And because this glue is specially designed for Perspex® cast acrylic, it cannot be used on any other material. So before you start any DIY projects using Perspex® cast acrylic, make sure you purchase the right glue!
For the purpose of joining two pieces of Perspex® cast acrylic together, you will need a product called Magma Bond C1 (similar to Tensol™12). This versatile glue can be used for general work that doesn’t require high bond strength. But note that this is not recommended for joining different materials together - such as Perspex® cast acrylic and wood.
Now that we’ve established the difference between Perspex® cast acrylic glue and normal household glue, it’s time to learn how to join two pieces of Perspex® cast acrylic together!
A Step-by-Step Gluing Guide For Perspex® Cast Acrylic
1.Choose Your Work Area.
When selecting your work area, avoid glass or paper surfaces, and rather choose a concrete, metal or wood surface.
2.Prepare The Joining Areas
Ensure that the surfaces you are joining together are clean, smooth and flat. You can sand each edge lightly, or use a router to ensure the surfaces are ready for gluing.
3.Wear The Right Safety Gear
When dealing with or cement, make sure you wear gloves and safety glasses to avoid contact with toxic chemical solvents.
4.Pour The Cast Acrylic Cement Into The Applicator Container
Using a funnel, pour the cementing liquid into the container until it is about ¾ full.
5.Position Your Perspex® Cast Acrylic Pieces
Put your Perspex® cast acrylic pieces together in the position you want them to be joined. For a 90-degree angle: use a combination square to ensure your pieces are properly aligned.
6.Squeeze A Little Air Out Of The Applicator Container
Air pockets can cause to pour out in a splatter and spoil the sheeting’s surface. That’s why you should give the container a gentle squeeze to allow some of the air out before application.
7.Apply The Perspex® Cast Acrylic Glue
Hold the two pieces of Perspex® cast acrylic in place with a steady pressure (use a clamp if you battle with this) and position the tip of the applicator container near one end of the join. Gently squeeze a straight line of along the join – the cement will run in between the joined edges.
Perspex Tip: If the Perspex® cast acrylic cement drips onto an unintended area, it’s best to leave it to evaporate, as you can spoil the sheeting surface by wiping it off.
8.Leave The Perspex® Cast Acrylic Glue To Set
Hold the join together (with your hands, or a clamp) for a few minutes, and then leave the cement to set. It should take 24-48 hours for the Perspex® cast acrylic pieces to fix firmly together.
You should now have a lovely clear join that’s ready for action!
