Epoxyed sink to corian counter.
 
So how do you cut though the epoxy on a bathroom sink to countertop (undermount)? Plus they over did it with the epoxy. I took my oscillation saw. And went through a couple blades and still didn't cut the epoxy out. Need to replace the sink.

No clips. Or silicone. All epoxy. It's at my brothers place . If it were anyone else I would even mess with it.

I've already googled it alot. Several people asking how to cut through it but no answers that I saw. Any suggestions on how to remove sink?.https://uploads.tapatalk-cdn.com/201...b101fb93e5.jpg

Heat the sink with a propane torch till the epoxy melts??

(No clue, Just throwing one out there.)

I put a sink removal bit on a router: https://www.amanatool.com/57166-carb...th-of-cut.html

It's pretty dusty.

The guy in the above video is an idiot. All non-solid surface sinks must be mechanically fastened. No Liquid Nails as it will bleed through some stones, just silicone to act as a gasket while a HUSH does the work: https://www.braxton-bragg.com/index....bc/0,8459,9145

I think that was just silicon. Didn't see epoxy on the flange when he dropped it down .

I wish this was just silicone. It has twice the epoxy it needs.

Think the corian will do ok with me and a torch? It's only bright white now.......lol

Yikes. In pieces? Put down lots of cardboard for protection, then hammer, chisel, grinder with vacuum shroud.....There's a chance it could crack, though.

My fear is cracking the counter.

China bowl - Wouldn't risk trying to break the sink up. Really stuck with using a grinding wheel to cut sink free just belwo the epoxy. And then grind or belt sand the epoxy off.

I'd take the top free and do the removal outside, if possible.

How big a concern is dust? I haven't swung a hammer in a while and I've never done this and I'm not sure it'd work, but - could you cut all the way around the bowl just below the counter with a grinder and cut-off wheel to remove everything but the rim, and then use a grinding wheel to take the rim off once it's gone? Unless there's an epoxy-dissolver of some sort, that'd probably be what I tried.


Or use the bit Kowboy posted, but I'd probably try it with tools I had first if it was a one-off thing.

Faster typing than me :thumbsup:

If that is a porcelain bowl, I'd pull the top and chip off as much of the polyester (it's not epoxy) as possible. Tape some tripled up paper towels to the joint, saturate them with acetone, cover them with clear plastic wrap to prevent evaporation, and tape the plastic wrap. You should be able to get the polyester to fail.

You could simply buy another sink with a footprint larger than the existing. Cut through the top with a jigsaw, secure the new bowl in place, run a bowl finishing bit around the raw edge, sand and refinish the top.
