Corian joint

FastEddie | Posted in Construction Techniques on June 4, 2009 08:06am

Found this joint is a countertop when I went to inspect the project.  This had been installed about a week before.  I am really surprised that the installer did not catch it, and the gc proj mgr did not either.

    Sweeett.....you need a bigger base for the monitor- it doesn't fully hide the joint.

    Could something have stressed the joint before it fully cured?

    Like a PC tower crammed under the counter or something.

    Even a hack would have done a better job a hiding that.

    Personally never worked with the stuff.

      I don't think so, the edges of the corian joint were clean as if they were waiting to be bonded."Put your creed in your deed."   Emerson

    is there a heat source nearby or is the sun coming through the window and hitting it.i used to work in a cabinet shop. one day we had made some corian counter tops they were a dark quartz color we set them out on saw horses in front of the shop to finish sand them. when we set them up they were in the shade but in the after noon the sun shined on them four about an hour while we were gone  lunch and some of the joints that had been glued up the day before came apart.

    I see 2 problems. Joint wasn't clamped and wrong color seam-fill.

    Normally I'd have less than half that wide of a joint. Hot melt glue wood or corian blocks to the top and close it up with handscrew clamps till the seamfill squishes out evenly and leave enough for a bond/blend.

    If that was top was for me, it'd be getting redone.

      I'm with you - get it redone / installation finished.

      Although FastEddie might be on to something.....

      Not positive what that white thing is under the right side - file cabinet maybe?

      I'm working in that.  Have not done the punch list walk through yet ... it's going to be a doozey.  I was rushed last time and didn't have time for a good review, but it looks like the millwork was not built according to the approved shop drawings.  :)    Like ... mdf where cabinet grade ply was spec'd.

      I don't think it was heat related, or split by an outside object.  It's a bit of an awkward installation, about 30 ft long with a dog leg in the middle, and I think they got in a hurry.  And maybe the adjoining walls were not exactly where they were supposed to be."Put your creed in your deed."   Emerson

    Hacks-R-Us?

    looks like a solid surface edge on a laminate top.  No matter what it is, it wasn't done right.

    Try cleaning out the caulking, installing draw bolts underneath and maybe, just maybe you'll get lucky and not have to tear it out and recut/reglue.

    Was it seamed on site? Is it actual "corian" or another brand like LG or Meganite? I know that some of the Meganite adhesive was bad, but the suppliers were sending it out and anyway. We had glued one up and the stuff never cured. They replaced all of the material, but the day and a half of labor was wasted. If it's Corian, they should be using Corian brand adhesive and not the Hanex or what ever brand is laying around. Was there no scab under the seam? What method of seaming was used? Butt joints are worthless especially when they are floating like your appears to be. A scab under the seam would have helped, but there should have been a wavy edge or some other type of seam done. I'm not the final say in solid surface for sure, but it looks like a poor job. It's definitely the wrong color adhesive. The stuff for that color should have been clear with a black tint. Even still, that wouldn't cause it to fail, but shows that the fabrication was poorly done.

    Thats a redoe for sure. When I was doing Corian that splice wasnt approved. It had to have a backer under it. Since it was 30' long they probably made that joint on site I'm guessing and they rushed it. The different color is not so bad as we (sometimes) did that on request.

    It should be a fairly easy fix for them. Especially ifn they want their money lol. I have had worse like once while routing out the sink the bit came out and demolished that under mount sink. Threw that router out the window too after that.

    Of course we installed Corian only. The rules for joints may be different for other manufactures. And it has been 18 years ago since I did it.

      Maybe you're not seeing it right.  The subsrtrate is a double layer of mdf, the majority of the top is formica, and the edge is corian."Put your creed in your deed."   Emerson

        Oh, I didnt see the fomica. Did they splice the dbl layer at the same spot? And the corian doesnt have any epoxy in it either nor look like it ever did.Due to the recent state of the economy, the light at the end of the tunnel has been turned off

        1. FastEddie | Jun 06, 2009 03:15pm | #16

          I'm going back today to do some more work and I'll check the whole thing closely this time.  I suspect the entire top is jointed there, they probably made it in the shop in 3-4 pieces and assembled on site."Put your creed in your deed."   Emerson
