Best way to cut corian?
« on: February 16, 2020, 09:58 AM »
Hi guys, I need to cut corian to size and make a few holes in it to mount a toilet. I have not worked with this material before so to avoid any mistakes I'd like to fall back on your expertise.

Unfortunately I am a bit limited in my tools at the moment as I am 750 km from home to redecorate an apartment in Germany, high up in the mountains near the Swiss border.

What I have with me is the TS55, the router, jigsaw, and drill with hole saws.

What would be the best way to do this? Is this sturdy material, or easy to mess up?

BTW, my view now:

Anything Tungsten will do the trick. To make sure you get nice edges I would cut oversized and clean up with a router (as far as stuff is in sight). To glue Corian onto anything use acrylic, preferably in the same colour.

If you can, use the special saw blade FS sells. Its geometry is better for the intended use.

I use the blade Festool sells for solid surfaces.

As noted above a slight over size cut and router clean up is good practice. You can cut to size if the edge detil will remove any defects.

If you're doing a build up use the recommened adhesive. You'll need the proper gun for the adhesive.

The stuff gets slick as snot, use spring clamps and back up blocks. Hot glue the blocks on, denatured alcohol disolves the hot glue for removal.

With build up, always over cut and router trim back.

I use drywall shim to make the templates.

Hole drilling, I prefer a sharp toothed hole saw over an abrasive hole saw. Do not use an auger or paddle bit.

If you need to build up the edge to make the top appear thicker than the sheet material. Pretty common practice.

Scuff sand where you need to glue, wash clean with denatured alcohol.

The gun and adhiesive tube is visible in this picture.

Thank you for answers. I work for an interior decorator and he slipped this in at the last moment when I was already loading the van and didn't have time to research this and properly prepare.

I have the standard blade and the special laminate blade with me, so I'll cut it oversize and then trim with the router.

I do not have any special glue with me like the 2 part glue you show. I only have standard construction glue with me, called 4tecx High Tack and considered as an excellent general purpose glue for a wide range of materials. Would that suffice or do you really need special glue?

I do a fair bit of Corian fabrication and I would strongly advise you to only use the 2 pack adhesive as mentioned by the other posters.

I have heard of people using CA glue with success on very small pieces, but if you are glueing edges to create what appear to be thicker panels, you will need the proper adhesive.
Also, to ensure the manufacturers warranty would be valid, you have to use the correct adhesive.....Sorry Alex....!

You have to use the proper adhesive. There is nothing that sticks well to solid surface material.

Any chance your there long enough to order the product and gun to assemble later in the week?

Make sure you order the proper color, otherwise you may have a visible seam line along the edge.

Nice looking area you'll be working in by the way.

Be especially careful protecting your lungs from the dust.
Cutting synthetic “stone” composites produces about four times as much silica dust as cutting granite.

Thank you all for your answers, I will track down the proper glue, my designer is in contact with his supplier to have it send out to me. I won't be needing it until next week.

I do not need to polish it, designer wants the matte look, apparently that's totally the thing now over here.

And I'll wear my respirator when cutting it.  [smile]

To 'glue' Corian and such onto different substrates (for instance plywood) my go-to furniture guy uses "Simson Professional BSR 50-10 Acryl Universeel (wit)", and so do I : ) . Dots or beads, not full area's.

Usually Scotch Brite is used. The finer the higher the gloss.

Check with the supplier for the recommended adhesive to mount the top to the cabinet. I use Sil-A-Bond.

Also if the top of the cabinet is filled solid, cut a lot of it out. The wood expands and contracts differently than the solid surface.

Looks like I’m mistaken.
Striking out looking for what I thought I heard or read about it having four times as much silica.

Everything I see comparing synthetic stone to granite says it only has twice as much silica as granite.

“The countertops are made from processed quartz, a material containing silica levels as high as 90 percent, or twice the amount found in granite.”

This place says it’s up to 95% silica but they sell dust collection systems.

I don't know, don't ask me such difficult questions!  [smile]

It is the first time I'm working with this stuff. I didn"t even know you can sand it.

I asked my designer to ask his supplier and the answer he got back was that you can use any good construction glue to glue corian on other materials, he specifically mentioned the 4tecx glue I have. But you have to use the 2 part glue Tom mentioned if you want to glue 2 plates of corian together, and then you can sand it to make the connection seamless. Looks like I'll have to do both.

But you have to use the 2 part glue Tom mentioned if you want to glue 2 plates of corian together, and then you can sand it to make the connection seamless. Looks like I'll have to do both.

I'm going to explain an earlier statement I made. The reason you should not place solid surface matierial on a full top cabinet is they move very differently. Solid surface moves with changes in temperature, wood moves with changes in moisture. You don't want the products fighting with each other.

Never use an adhesive that hardens for the install, it must stay flexible, why I use Sil Bond. A veryslight gap to the wall is acceptable. The tops move.

A few pointers on using the two part adhesive;

Get extra mixing tips---at least six more, that should give you 8 tips. I buy them a box of 50 at a time.

Make sure you get the gun for the 2 part.

Place the tube in the gun, it will only go in one way.

Remove the caps from the tubes, do not install the mixing tube yet, hold the open end of the tube about 1" above scrap card board, squeeze the trigger until you get material to just expose.

Install the mixing tube, again over the cardboard squeeze the trigger until you get a dollop of adhesive on cardboard about 1" in diameter and 1/8" high. This gets the tube "primed".

You must do the above every time you need to apply adhesive.

Run a bead about 1/4" from the edges, run a squiggle between them.

Once done applying install the build up, next step, remove mixing tube, reinstall caps.

A few on doing the work;

MAKE A TEMPLATE

Make sure you glue on the back up blocks. Any other way is a lesson in frustration.

Clamp the build up where you want it, glue on the blocks with just a corner touching the build up.

Install one piece of build up at a time.

Practice with how you put the clamps on, you can move the build up around with the clamps when the adhesive is wet.

If there is a corner that needs build up, use a lap joint.

DO NOT wipe off any squeeze out, sand it off latter.

You'll need build up along the unseen sides. I use 15/16" strips of MRMDF (thickness assumes 2 pieces of build up stacked), you can use scrap solid surface.

I flush everything up using 2200's with special bits in them, then I sand.

Try to do any polishing before installing.

I'm sure I forgot something---good luck.

The one with the octagon weighed over 600 pounds. There is a staircase in a location where you can see the bottom of the top. It is kinda hollow, but appears solid. Forgot, the leg you see with the outlet/receptacle is hollow solid surface.

Wow, so much info, I knew you guys wouldn't let me down.

Thanks Dan for that resource article, that's gonna come in handy.

And thanks Tom for that very detailed explanation, I'm sure that will save me some frustration indeed.

Looks like working with corian is a whole trade by itself, my head's still buzzing from learning how to plaster the last 3 months, now I'll have to find a corner somewhere to stuff this information.

Tom, I won't be glueing this onto wood, but on a built-in water reservoir for a toilet like this:

One more point to add to Tom's detailed info.....

Wherever you make a cutout in the Corian, dont leave any  sharp internal corners. Always leave a small radius in the corners. For example, the cutout for that rectangular Flush Valve, I would make a template jig and cut it out with a router.

Good Luck with it Alex!

One addition to Tom's detailed description is you only have about 5 minutes working time before the epoxy starts hardening both in the mixing tube and your project. Thats why the extra mixing tubes are recommended. A couple of dozen 2" spring clamps are your friend for small projects, I have 100+ for corian countertop glueups.

 [eek]  Blimey!,....The weather must be a lot hotter in Canada than I have been led to believe!

Even in the height of Summer over this side of the Pond, you will get 15 to 20 mins before the adhesive sets hard.

In February in the UK, in an unheated workshop, its closer to 45 mins......

The glue nozzles are a one time use, but you do normally get 2 with each tube of 2 part adhesive....

Told you there were little things I forgot. Thanks for covering them.

One more thing----scuff sand where you're going to apply the solid surface adhesive, 150-180 grit will work.

I'd still use Sil-Bond to mount the cover to that frame.

Clamping the build up for the piece that will go on that frame, I'd have about 150 clamps on it. I have ~600 2" spring clamps and run out at times.

Alex, go back and look at the pictures I my previous posts, they will make this all much clearer.

Depends on where you live, this area can see highs close 100F and lows to -25F. I also never work in an unheated shop in Winter or an uncooled shop in Summer. I was also lead to believe all you got was rain and fog, LOL.
 
I would also assume being on a different continent you might have a different epoxy supplier hence the difference. So maybe when Alex does his glueup he can pass on his experience, like Tom and I have passed on ours.

 A very simple glueup might take 2 tips from my experience, on some larger jobs I've 8 or 10 tips.

In an earlier post I stated "clamp on the build up, install the glue blocks".

To be clear this is a dry fit. No adhesive until the blocks are in place.

I would suggest to think about using magnets to stick it to the metal in-wall frame. While the mechanism can be serviced solely through the hole (the plate with the buttons goes to) it can be beneficial to have a way to access the inside of the wall in a non-destructive manner.

I'm curious too about handling seams. Do you use painters tape or something similar along each edge to prevent squeeze-out from contacting the finish surface and trim off any ooze. Or is there very little extra is applied properly. If you want to fill right up to the edge as Alex asks about it would seem you can't hold back too far from the edge as you might with wood glue.

I don't have anything coming up in the near future like this but would like to know how to handle it if/when I do.

Dupont do some excellent guides. I've attached a few that might be of use regarding the various questions posed in this thread.

Solid Surface adhesive, no matter whether its Corian or another make, is very fluid and spreads very easily when 2 surfaces are clamped.

For example, in the picture posted previously by Bob D,.... 2 good beads along that edge are all that is needed and when the 2 sections are clamped together, the adhesive will spread out and ooze from the front and back. Once cured, the excess is machined off and sanded .......DO NOT ATTEMPT TO REMOVE ANY OF THE EXCESS ADHESIVE WHILST IT IS STILL WET......!

Excess clamping force is also to be avoided.....If you over clamp the joint, too much adhesive is expelled and it is known as "Starving the Seam".
Very accurate machining, preparation and cleaning(especially the light colours) is the key to achieving a "seamless" joint in the mating surfaces.

Little pin holes can be filled if necessary afterwards, but if you have applied the adhesive in the correct manner and to the correct quantity, this scenario will be avoided.

@Alex  Corian is not the only 'sheriff' in town. And the competition has some nice resources for craftsmen. Like this one:

Just a little OCD Bob, LOL
That would be spacing the ones with the barcode sticker evenly...

How on earth do you have an orange clamp in there?  I would have to throw that away instantly, having one rouge clamp would drive me nuts.

Anyway,  Alex, nice work site, no different than what anyone working off the NJ turnpike would see every day of the week.  [big grin]




Proof that one can never have too many clamps. :-)

Sorry Alex, couldn't resist.

Now back to our regularly scheduled program.

Once the pieces are placed on the adhesive, the least of your concerns would be the bar codes. Limited time to get these on.

I'm already nuts, that clamp has no affect on me [big grin]

You're correct, one cannot have to many clamps, I have ~600 of these 2" clamps and run out at times. Color be damned..... [scared]

The reason for the tight clamp spacing, is to get a "seamless" seam you need some glue squeeze out. The clamps spaced this way prevents voids in the bead of squeeze out. This bead of squeeze out gets sanded off after the adhiesive cures, this process creates a "seamless" looking joint.

For top surface joints I have vacuum clamps that draw the joint together, done properly is is very difficult to find the seam/joint.

Just one more question, if you glue the seams, do have to make absolutely sure it is filled in one go? Or is it possible to apply a bit more glue later if you find any dimples?

A proper bead and clamping solves the void issue. This is one of the most important processes in solid surface work.

I've had it go both ways, sometimes I can add some adhesive, other times I've had to insert a Dutchman.

Tom, I assume you start in the middle and then work to each end?

I'm left handed, work right to left with the clamps. Never found a need to start in the middle, don't recall ever having a "trapped" piece of build up.

Thanks everyone, I understand enough to get myself in trouble now. :-)

JK, I think I've got the gist of it. Thank you all.

For clarification that was not my pic but one I re-posted from earlier in the thread.

@GarryMartin thanks for that, seems I got some reading to do.

@Alex  Corian is not the only sherrif in town.

Well, it is for me now, hier in m'n hutje in de bergen. Stuff's already bought and paid for. When the designer first told me he  wanted to use corian he only asked me if I could cut it. Well, why not I thought, I have the special blade for my saw, and I have  a router. Just another composite material, no fuzz. I didn't know it is a kind of tricky material that needs its own special approach.

But I don't shy away from a challenge and am always eager to learn new things. When the designer heard my questions about the glue he just said, sod it, lets just tile it over like the rest of the bathroom. But then we'd have to trash the corian, and people say I'm a handy guy so I try to live up to that reputation. If I mess it up I can still revert back to tiles.

@Alex sounds like a perfect situation for getting some experience with this stuff. An easy going client with a backup plan and material on hand.

WHOA!  [scared] That seems somewhat abusive towards my people.

And I'm not sure how I'd manage that, I've only got one, and I'd like to make good use of him for the rest of my life.  [big grin]

Yes, good to try new things Alex and next time you'll know just what to do.  8)

I have not done a worktop in Corian or other engineered material yet but I expect to one day soon so glad this subject came up.

Wife has been hinting at me to build a countertop with some storage underneath in the laundry room next to the washer and dryer.

Thanks for posting the guides @GarryMartin
