Cutting and seaming solid-surface materials like Corian can be tricky, especially if you have zero experience working with such materials. Fortunately, there’s plenty of information available to help you accomplish a DIY cut and seam with ease. Before you break out hack saw and cleaning cloths, you’ll want to familiarize yourself with a few basic steps.

To cut and seam Corian, builders will need to research the right cutting tool. Then, gather supplies, put on safety gear, and prepare the solid surface material. Check alignment and secure the material, then cut. Clean the seams and apply epoxy. After letting the materials harden and set, sand and buff to finish.

In this article, we’ll go step-by-step and explain how to cut and seam Corian correctly and efficiently. After reading this guide, you may feel more confident about tackling a Corian-based project. You may also experience better, cleaner results.

Research Cutting Recommendations

It’s vital to spend a little time researching the proper cutting tools before attempting to cut and seam Corian. If you’re not experienced in cutting this type of material, you may accidentally choose an incompatible cutting tool. The results could be disastrous for both you and your Corian material.

Consequently, it’s crucial to peruse helpful manufacturer documents before gathering your supplies together. After all, not all cutting tools are created equally. Some might be too small or weak to handle Corian, while others may be overpowered and challenging to control.

The most commonly recommended device for cutting Corian material at home is a standard-sized circular saw. But you could also opt to use a beam, drop-cut, or radial arm saw. It would be best if you always used toothy blades that are approved for use with hard plastics.

Once you feel confident that you know which tool to use, you’ll want to begin gathering your materials and supplies together. It can be frustrating to pause a project halfway through because you need a new saw blade or a different epoxy type.

Gathering the right supplies before preparing your Corian material is essential to enjoying a high-quality cut and seam job.

Gather Your Materials

There are quite a few items you may want to have on-hand before cutting and seaming Corian. While the material itself is crucial, there are also a few adhesives, sealants, and cleaning tools you’ll want to secure.

It’s a good idea to come prepared with:

  • A pencil, pen, or marker
  • Safety gear
  • A circular saw
  • Masking tape
  • A straightedge tool
  • Clamps
  • Guide fences
  • Seam support strips
  • Silicone caulking
  • Epoxy glue
  • Several cleaning cloths
  • Rubbing alcohol
  • Thick wooden blocks
  • Sandpaper of various grits
  • A compact sander
  • A buffing pad

While this may seem like quite a long list of supplies, each item is necessary for the job. When choosing a marker for your material, it may be best to use one that can settle into plastic surfaces. It’s also worthwhile to look for a marker with a fine or medium tip, and one with ink that contrasts with the color of your Corian material.

The silicone caulking that you choose should be a close match to your material’s color as well. This way, the caulk can hide the seams and form a more attractive and protective border along your material’s edges.

Before moving on to the next step, remember to ensure that your circular saw’s blade is in good shape. Also, be sure to check all of your safety gear for signs of damage. Wearing a cracked pair of safety glasses is just as dangerous as having no eye protection.

Put On Your Safety Gear

Once you’ve gathered all of your tools, supplies, and Corian material together, you’ll need to suit-up for success. This means donning your necessary safety gear. While you may want to skip or ignore this step, doing so could lead to a painful injury. Whenever you’re operating power tools, you’ll want to protect your eyes, hands, and face.

This means putting on a pair of wraparound safety goggles or safety glasses. You’ll also want to slide your hands into a pair of durable, form-fitting work gloves. If possible, you may also want to apply a chain mail weave over these gloves. Reviewing official safety recommendations can help you familiarize yourself with the proper safety apparel.

It’s also vital to wear a protective face mask before cutting into Corian. Airborne particles can be harmful if inhaled. If possible, choose a mask with a built-in respirator. And remember, though you may feel silly or overprotective while putting on your safety gear, you won’t feel quite so awkward if your gear helps to save your life or keep you safe from harm.

Lastly, you may want to consider using earplugs. The average circular saw generates a reasonable amount of noise, which could contribute to long-term hearing loss. Wearing sound-canceling headphones or earbuds could help reduce or prevent hearing loss associated with power tool usage.

How to Cut and Seam Corian Step By Step

How to cut and seam Corian.

1. Draw Your Cuts

Once you’re safely ready to go, you can take your pen or marker and begin drawing your planned cuts. You may want to begin with a pencil, especially if you’re not accustomed to using a straightedge or ruler for assistance. Of course, your masking tape may also come in handy for this step.

You can place masking tape along the borders or edges of your Corian material and draw your cutting line atop the tape. This will protect the underlying material while also helping you achieve a more exact cutting line. The tape could act as a supplementary guide while you apply your guide fences.

The straight-cut fences should be secured via wood clamps, though spring clamps can also be used for this part of the process. Once your material is secure, you could measure your pre-cuts to ensure they’re correct.

Drawing your cuts beforehand is crucial to achieving a high-quality seam. If you need to make a few more adjustments, you could attempt a ‘dry run’ with your circular saw before taking final measurements.

2. Check Your Alignment

Go ahead and grab your circular saw, but don’t plug it into a power source yet. Lift any security covers and unlock any safety mechanisms to allow the blade to come into contact with the material. Then, slide the circular saw down the length of your fences.

A straight cut guide for circular saws is crucial for this step. If you don’t already own a sturdy pair of guiding fences, you may want to check out the Bora WTX guiding fence.

With a 50-inch cutting length and a rugged aluminum body, it’s bound to help you cut Corian more efficiently and precisely. It can also withstand the force of a sliding saw, making it ideal for this particular step.

While you slide along the guide fences, check to ensure that your blade is consistently aligned with your cutting line. If it isn’t, you’ll either need to double-check your line’s accuracy or adjust your fences. Still, this should only take a minute or two.

3. Secure Fences and Clamps

Once you’re entirely comfortable with your prospective cut, you’ll want to make your final measurements. Double-check your clamps to ensure that your guide fences don’t wiggle or shift during the cutting process. Finally, you’ll connect an appropriate circular saw to a power source and begin cutting the Corian material.

4. Carefully Cut

When making your cut, you’ll want to ensure that the blade is set to a slightly greater depth than your material. This ensures a clean slice that looks professional, maintains the material’s integrity, and is easy to wipe clean and adjoin to other pieces.

Take your time when cutting through the solid-surface Corian material. Wood is far easier to penetrate than Corian is, so you’ll need to slow down your feed speed for this project. However, you should always be moving slightly forward through the material.

If you stop in a specific place while attempting to make your cut, you may end up with burned material. The rapidly spinning blade produces a certain amount of heat, as does the small motor in your saw. Because of this, the acrylic components that make up the Corian could begin to melt and crumble.

Not only will this result in an acrid, toxic smell, but it will also damage your material. Should you need to pause or take a quick break from cutting, you can turn the power off on the saw and remove it from the material when the blade is stationary. Never pull an active saw from Corian that is still in the process of being cut.

Not only is it dangerous to do this, but it could also result in an uneven and unsightly cut. Still, when you’ve continued through the Corian and finished your cut, you can unplug your saw and store it away for later use.

From this point forward in the cut-and-seam process, you’ll primarily be working with epoxy glue, silicone caulking, and cleaning rags.

5. Wipe and Clean

Go ahead and grab a few cleaning cloths or rags. You may also want to locate your rubbing alcohol. Using one of these cloths, wipe any excess debris or splinters from your newly cut edge. You’ll want to keep your safety gloves on for this step.

You have to wet a separate cleaning cloth with alcohol and wipe the same edges once more. Any leftover dust or residue will wipe clean once you apply rubbing alcohol. You’ll also end up with a surface that adheres to other materials well. When you’re seaming, this is crucial.

Without contaminating your newly cleaned edges with body oil or dirt, go ahead and ready your support strips and caulking. If you’re unfamiliar with caulking, you may want to review a quick guide on how to use a caulking gun effectively. Otherwise, you may be in for quite a mess.

6. Apply Support Strips

After cleaning your Corian material, you’ll want to take a moment also to wipe your seam support strips. You can use the same alcohol-dampened rag to do this, though a clean cloth may provide better results.

You’ll want to wait for any remaining alcohol to evaporate. Then you should begin to apply silicone caulk to the edges you intend to join. Press your seam support strip beneath the seam, being careful not to exert too much pressure.

Wait several minutes before moving on to epoxy application and setting. This will give your support strip additional time to settle and secure itself. Having a little extra patience during this step can help ensure that your final result is both durable and attractive.

While you may not feel like these support strips are necessary, a countertop or solid-surface piece of furniture can suffer without them. Corian can be a heavy material, and it requires a substantial amount of support to remain level.

As such, though it may be tempting, it’s crucial to take your time with this step and ensure that your support strips are secure and set. Doing so could mean the difference between a long-lasting Corian centerpiece and a misshapen DIY construction disaster.

7. Apply Epoxy and Set

Working with epoxy glue can be a challenge. Not only do epoxy glues form a relatively permanent bond, but they can also emit some toxic and unpleasant fumes. If you’re not wearing proper safety gear, including gloves, a face mask, and eye protection, you may be putting yourself at risk while working with epoxy glue.

Before applying your epoxy adhesive, you may want to turn on nearby exhaust fans or open a few windows. If you’re installing Corian kitchen countertops, you may want to try using your oven’s exhaust fan to keep your home’s interior air from becoming toxic. Still, this part of the cutting and seaming process should be completed away from small children and pets.

Prepare your epoxy glue according to the manufacturer’s recommendations. Then, apply a thin layer onto the edges you intend to join. You could use a small paintbrush to achieve an even coating, but most store-bought epoxy glues include an application brush that is designed for the job.

You’ll also want to paint a thin coating of glue onto the support seam you placed. Be sure that the glue you apply will adhere to the bottom surface of your cut Corian. You’ll also want to employ your wooden blocks. Apply a coating of epoxy to your blocks and place them on the pressure points of your structure.

When you apply your Corian material to this sticky surface, it will adhere beautifully and experience outstanding support. The wooden blocks will help prevent any warping in the material that may result from a lack of support. They’ll also act as a secondary form of anchoring for the Corian.

While the seam support strip is bound to grab onto the edges of your material, the wooden blocks can help lock the Corian onto the structure more permanently. You can use spring clamps or other types of material-safe clamps to help expedite the setting and sealing process.

Be sure to allow for plenty of time before attempting to sand or buff your nearly joined surfaces. If you act too soon, you may damage your epoxy’s bond, resulting in a loose and shifting surface. Check the manufacturer’s curing recommendations listed on your epoxy glue’s packaging or simply wait a full 24 hours.

8. Sand and Buff

Finally, you’ll want to sand your set pieces. Start with coarser sandpapers and slowly transition to finer, less abrasive options. Doing so can ensure you enjoy an even, smooth finished surface. However, while Corian is rather solid, it isn’t impervious to sanding damage. If possible, try to sand your material by hand.

If you’re unable to sand manually, you could use a power sander. You should still set this device to its lowest possible settings to avoid inflicting any damage to your newly set Corian pieces. Over-sanding could result in weakened seams and discolored material.

When you’re satisfied with your Corian’s surface quality and feel, you’ll want to begin the buffing process. Fortunately, you don’t need to use any expensive oils or waxes to bring out your material’s attractive shine.

Simply use a power sander and buffing pad to get rid of any stray particles, strands of dried epoxy, or bits of errant caulk. Reviewing a finishing and polishing guide can help you keep your Corian looking its best.


Learning how to cut and seam Corian material doesn’t require hours of study. If you can identify the best cutting tool for this solid-surface stuff, you’re on your way to getting the job done. After outfitting yourself in safety gear and preparing your material for the cut, you can secure your Corian and your tools with a few well-placed clamps and fencing.

Take your time while making the cut, ensuring that you’re practicing proper safety techniques and aligning the blade with the pre-drawn line. Afterward, you’ll want to wipe your new pieces down with a dry cloth to remove any shaved particles. Doing so can help your epoxy set more quickly and hold more effectively.

After giving your material plenty of time to harden, you can remove weights or blocks. Be sure to sand the Corian and buff it clean before giving yourself a pat on the back.
