Working with Solid Surface Material such as Corian™, a Follow Up

I was talking to Kyle Carpenter at a few weeks ago about working with Corian™ and some of the other materials used in solid surface countertops.  I asked him to send me a scrap piece or a drop end for me to practice some cuts,  seaming and  edge build-ups that I could form into a finished edge profile.  Thankfully this past weekend we were blessed with spring like weather and I was able to work outside.  You will need a level area to work in whether you do this inside or outside.

Since this was the first time I had worked with solid surface material, I was a little timid at first. However, after making my first few cuts I breathed a sigh of relief. First attribute I noticed was that since there was no grain in the material, chip out was not an issue. In fact I used my standard project set up without any issues.  I cut the material using my Bosch 36V Circular saw. The saw is several years old and the blade, a Freud Avanti is more than a year old.  The cuts I made were very smooth and would need little work before using them as seams.  Now I will emphasize that you will need to perform what is called the “mirror cut” to achieve a perfect seam that cannot be seen once epoxied together. This cut is covered thoroughly in the upcoming article.

I am now putting the finishing touches on our article for working with solid surface countertop materials so be on the look out for it.  What I can say  is that I worked with Corian™ material and I was surprised at the ease and workability of the product.  The highlight for me was cutting thin strips that I would use for my decorative edging, stacking them to form a thick edge, epoxying them together and then finishing them with my Skil 2 hp. router. Watching the edge transform from the rough glued up layers into a finished edge with a profile was akin to watching a butterfly emerge from a cocoon.

I sanded the surfaces up to 220 grit. Already i could tell that I could achieve a high gloss finish much easier than I could if this was wood I was working with.  There are some areas that will be covered in the article in detail, that I think a homeowner should pay close attention to, but all-in-all the material was much easier to work with than I had expected. Basic woodworking tools were used. The saw I have already mentioned. I used a Swanson Straight Edge for straight cuts. I used a Skil router and a Skil bit for the edge profile, but I used a 1/2 inch Bosch twin fluted bit for my seam cuts.  For clamping I used a Bessey “Bag of Clamps” on the edge build-up and for joining seams I used the same Irwin bar clamps I use on all of my projects.

After finishing the seams and edges and the sanding, I wish I had more material to experiment with. I know you can shape the material with heat and probably many other things you can do with it that I am not aware of. But for just plain countertops, if you can work with wood, then you can work with this material.

    If you are writing an article on working with Corian you may want to start with duPonts booklet “How to work with Corian in the home workshop” . It is now available on my site. along with my line by line notes to this 1995 classic.

    I can also give you many insights into Corian, since I have worked with the plant engineers and have spoken at length with its inventor Dr. Slocum.

    I am thinking of using products other than Corian (ex Silestone, Oakite, etc.) and am curious if they wold be as workable as Corian. I also would like to know f they can be obtained easily.

    I would think the surfaces would all work similar. But I would check with Kyle at Solid Surface. Here is his website. I have found Ed also to be a very valuable advisor on questions I had regarding working with the material.
