OT: Need Advice for Gluing Corian to Corian

Ok, I have a small project that is taking on a rediculous life of it's own. About a month (ok 3 months...I've been procrastinating on this one for a reason) the soap dish in my daughter's bathroom came loose and I had to remove it. It is a corian shower surround with a corian soap dish in each corner. One of them came loose because the original installer used some type of adhesive followed by a bead of silicone to install it and after 12 years it finally failed. After calling DuPont Corian, they only sell their "special adhesive sauce" to their distributors, you can't buy it retail. Well, they give me the number of their distributor in our area and they only sell it to certified DuPont Corian installers. So, I have an alternative which is to buy a product called Seam-It from Glue Warehouse which looks great but after talking to really helpful guy there, at almost $50 bucks for a single tube their glue, of which I'll only use a very small fraction with the rest being wasted, I also find out they have a special gun that dispenses the two parts and mixes them in a 10:1 ratio. He says, don't worry about the gun, just dispense what you need manually and mix it in about that ratio and you can skip the $70 gun they sell to go with the product. At this point, he kinda comes clean and says, really, any acrylic to acrylic epoxy will work for your application. I asked about Weld-On and he said he wasn't sure but maybe. Exhaused, I am reaching out to the RC / CMAS community for advice. Short of spending $50 bucks on Seam-It or getting some installer out here to gouge me to install a stinking soap tray, I need some advice from anyone who has had success gluing corian to corian. Thx!
 
what about waterproof epoxy? you can get the 2 part setup at HD and it might just work. I would make sure to clean the surfaces of soap before you glue. I'm talikng about the liquid version and not the clay type.
 
The corian glue kit is just color matched acrylic epoxy.

Yeah, I was starting to wonder if that's the case. What should I use, the folks at Weld-on said weld on 40 which is now sold under the brand Scigrip. Only available in pints which is way more than I need.
 
Yea I would give that a try and they sell it at home depot. Once it drys silicone all around it for more support. They r marking it way up on u at 50 bucks a tube.
 
Thanks guys. Got it done w some advice from a guy who has been installing and repairing corian for over 30 years.
 
For the soap dish I used a 2x4 cut to the correct height to support it. Then I used glue from a hot glue gun in 2 small spots where the dish met the shower surround to hold it in place for initial bond supported by the 2x4 in my case. Basically on the backside of the soap dish where the greatest surface area makes a bond I applied silicone first, leaving the two spots for the hot glue. I then spread the silicone evenly w my finger on the back side of the dish, applied the hot glue to the two spots I left for it and pressed the dish in place to be supported by the 2x4. I used 3m blue to mask and remove from the dish and surround so there was no mess from that initial setting in place.

After it set for about 6 hours, I proceeded to run a small clean silicone bead around the perimeter of the dish, on the underside too.

The guy I talked to steered my away from the marine epoxy, basically I did what he would have done if I paid him $125 to drive and do the same thing. I had all the materials on hand besides the silicone I wanted to use so it was a few bucks and a little time on my part to get it done.

He made a good point in that having the ability for the dish to give or "break away" on impact in a shower if someone slips might be a good idea. I considered that as well since it is a kids shower.
 
I would use the loctite tubes. Call loctite first though, I called to verify it would bond to stainless to drywall. They have a great customer service.
 
That was my inclination as well but got the advice from a guy that works with the stuff for a living after telling him that was my plan. He was really decent about walking me through it. If it fails, I will probably go that route next but I'm surprised by how solid it actually is now that it has cured. The adhesive from the original install failed because it got brittle over time and just gave out.
