What is Plexiglass?
Plexiglass is made of polymers of methyl methacrylate. So in other words, it’s made of plastic.
The scientific name of the compound is PMMA, but it’s commonly known as plexiglass or acrylic sheets.
Plexiglass is a practical alternative to glass because it’s shatter-proof, unlike glass. It’s lightweight and more flexible, so it can be used for many purposes without breaking.
Moreover, it’s more transparent than glass so that it can be used for printing.
Lexan is another polycarbonate plastic commonly associated with plexiglass, but while plexiglass is used for aesthetic purposes, Lexan is more often used to serve as a tough, protective covering.
However, it attracts dust and scratches easily, so it shouldn’t be used for purposes where it’s subject to mechanical wear.
Moreover, plexiglass changes its color over time and turns yellow, unlike glass, which maintains its color.
Nevertheless, due to its versatility, plexiglass has become extremely popular. It’s commonly used for car windshields, for example.
How to Maintain Plexiglass
Although durable, some people make mistakes while maintaining plexiglass, affecting its appearance. Here’s how to maintain it properly!
- Use the right cleaning agent when you’re cleaning your plexiglass. Some chemicals, like ammonia, can ruin it. A mild cleaning solution made of water and dish soap is strong enough to remove stuck debris without affecting the chemical composition of plexiglass.
- Don’t use a dry piece of cloth to clean the plexiglass. This will rub the dust particles into the sheet and cause scratches.
- If your plexiglass sheet gets scratched, you can remove the scratches using an abrasive polish. For more stubborn scratches, you can use sanding and buffing.
- Be careful while handling plexiglass sheets. Too much pressure can cause cracks.
What is the Best Way to Cut Plexiglass?
Several tools and techniques are available to help you cut plexiglass for various purposes.
Luckily, any DIYer can master these techniques fast, as long as you know the proper practices and take suitable precautions.
Thin plexiglass is the easiest to cut. All you need is a level surface that won’t wobble and a ruler to ensure you have the right measurements.
This method is called “scoring and snapping” and is best to use if you have a small DIY project that involves cutting plexiglass sheets into simple shapes.
Note: This method won’t work if your plexiglass sheet is too thick!
For more accurate cuts, you can use a circular saw. The teeth of the blades are able to cut through thick sheets of plexiglass with no issues.
This process is faster and gives accurate results.
If you wish to cut plexiglass into various shapes, you can use a jigsaw. Using the up-and-down motion, you can cut plexiglass sheets into circles, curves, and other irregular shapes to finish various DIY and professional projects.
How to Cut Plexiglass Without Breaking it
Plexiglass can make picture frames, printing sheets, windows, tabletops, and more.
Due to its versatility, it can be used for several DIY projects as it can easily be handled with your workshop tools. Here are some tips to help you cut it properly!
➢ Plexiglass comes with a protective film that protects the sheets from scratching. You should leave the protective film on while cutting and shaping it.
➢ Make sure that you’re using the right tools and pressure. Otherwise, you’ll be left with irregular cuts and rough edges.
➢ You’ll have to spend some time smoothing out the edges.
How to Cut Thin Plexiglass
Plexiglass is exceptionally durable but not difficult to cut if you have the proper knowledge.
Learning to cut thin plexiglass depends on using the right tools and techniques.
1. First, consider how thick your sheet is because it will help you choose the right tool to cut it. Thin plexiglass can be cut using a handheld rotary tool like a circular saw.
For thicker plexiglass, you should use a scroll saw.
2. Thin plexiglass is easy to cut for DIY projects. The following method works when you want to cut your sheets into simple shapes made of straight lines. Here is how to do it.
3. Place the plexiglass sheet on a flat work surface. Make sure that there are no objects that can affect the accuracy of the cut. The table or workbench should be level and clean.
4. Use a measuring tape or ruler to draw a line using a grease pencil or a dry-erase marker to show where you want to cut the plexiglass.
If you make any mistakes, erase the drawing and start again to make sure that there will be no errors. Don’t smudge the line to ensure your cut will be accurate.
5. Use a glass cutter to score the plexiglass along your drawn lines. Do this about 10 or 15 times until you see a deep groove.
This is where the plexiglass will be cut. If you can’t find a glass cutter, use a utility knife
6. Flip the plexiglass over and repeat the scoring process on the other side. Follow the same line until you’ve made a groove.
If the cutter doesn’t work, you should use a special scoring tool. Deeper cuts allow you to finish your job accurately and fast.
7. Move the plexiglass sheet carefully and bring the scored section to the end of your work table.
The part that you want to cut should be hanging off the table. This is how you’ll be able to snap it easily.
8. Use a C-clamp to secure the plexiglass sheet. This will prevent it from moving so your cuts will be accurate, and the sheet won’t accidentally break.
Ensure you don’t tighten the C-clamp too tight, as it might leave a dent in your plexiglass sheet.
9. Apply downward force along the scored line. The plexiglass should snap and break; however, the edge will be visible and affect your finished project’s overall look.
If the sheet doesn’t break easily, use your utility knife to cut it properly.
10. Use a power saw or sandpaper to smooth out and buff the edges of the plexiglass.
Use 120 or 180-grit waterproof sandpaper and a rubber or wood sanding block to smooth the rough edges.
It would be best to switch to finer grits, like 600-grit sandpaper, when the edges become smoother.
11. Start buffing with a quality buffing pad. Use a polishing compound to give your plexiglass the perfect finish.
How to Cut Plexiglass Without Cracking it
If you’re not careful while scoring and snapping your plexiglass sheet, you might accidentally crack it.
This is why most DIY enthusiasts and professionals prefer using a circular saw vs a table saw.
This method works best if you have a thick sheet of plexiglass and helps you finish your project quickly with accurate results.
How to Cut Plexiglass with a Circular Saw
Use a circular saw to cut your plexiglass sheets into straight lines to make fast and accurate cuts.
1. Before cutting, check out the blades of the circular saw. The teeth should be evenly spaced and the same size to guarantee that the cut will be accurate.
A fewer number of teeth on the blades ensures that there will be no dust or debris flying into the air.
Use a carbide-tipped circular saw blade to accurately cut through sheets without dust flying into the air.
2. Place the plexiglass sheet on a sawhorse to keep it flat while you’re using the circular saw.
Use a ruler to make a mark using a dry-erase marker to draw the line where you’ll attempt to cut the plexiglass sheet.
Ensure the two halves are appropriately balanced, so they don’t fall to the ground when you’re done cutting.
3. Align the circular saw’s cutting guide with the mark you’ve drawn using your marker.
4. Start your circular saw and bring it to full speed before attempting to cut the plexiglass sheet.
If you use the circular saw before the blade rotates at full speed, the teeth might snag on the plexiglass sheet and cause a chapped or inaccurate cut that you’ll have to fix later on.
5. Wearing protective goggles is essential when cutting a plexiglass sheet with a circular saw.
They will protect your eyes from flying particles that could potentially cause serious damage.
6. Apply some force to push the circular saw forward along your drawn line.
Make sure that you apply steady force to prevent the teeth on the blade from jamming.
Going too fast can cause the saw to catch on the sheet.
If this happens, stop and bring it back to the original pace, and then push the circular saw again through the sheet.
Best Way to Cut Plexiglass Curves
A jigsaw enables you to make circular cuts or curves in the sheets of plexiglass. It can also make straight cuts and other irregular shapes, so you should get one if you’re working on a complicated project.
Here are the steps to create curves for different DIY projects!
1. Pick an uncoated blade with fine teeth to cut plexiglass without debris and dust flying over. You should have some extra blades ready, so you can replace yours when needed
2. Place the plexiglass sheet on a sawhorse. Ensure that the sheet you’re using is stable and doesn’t move to guarantee the accuracy of the cut.
3. Use a stencil, a round object, or a compass to draw the curve or circle you’re cutting. Use a dry-erase marker to draw the line.
Having this line while using a jigsaw is crucial to guarantee that there will be no mistakes while you’re cutting the plexiglass sheet.
If there are any mistakes, erase the line and draw it again to ensure the accuracy of the cut.
4. Ensure you’re wearing your safety goggles while using a jigsaw. Splinters and dust can fly in the air and cause severe damage if they hit your eyes.
5. Use a drill to make a hole in the plexiglass sheet. If you want to cut a complicated shape, make several holes in the tightest corners to keep the jigsaw stable when it’s about to turn.
Otherwise, the blade might bend or break while you’re trying to turn it.
6. Fit the jigsaw blade through the hole in the sheet. Bring it to full speed before attempting to use it to cut a circular or any other shape.
A jigsaw moves slower than a circular saw, so you’ll have to wait until it reaches its full speed.
Be careful while using the jigsaw because the blade can break and injure you or others around you!
7. Follow the guide marks on your plexiglass sheet and apply moderate pressure while using your jigsaw.
If you feel the blade is catching, you might be going too fast. Stop and let the jigsaw return to its original speed.
