replacing bathroom sink & it's stuck

michee

I have a top mounted sink on tile and it has rusted through. Have removed caulking, all plumbing and undersink clamps. Have tried pounding aroung edge with a putty knife and it seems like it is SUPER GLUED...lol. Don't want to crack tile. Any suggestions?

That is not very common to have a metal Bathroom sink. When it was originally installed, there may have been a heavy bead of caulk applied under the rim before installation. Can you post a pic?

It was porcelin or cermic coated white over metal or whatever. Probably the cheapest sink you can buy...ecomony wise. Sorry to have misled you.

Michee, Welcome to the Forum
I have not done this but what I might try is to get a pint can of Acetone and try to get some under the rim from the top side with the aid of a putty knife.

Use gloves and eye protection and use sparingly. Acetone is nasty.

Thanks! At this point I am to the point if I can't do it, I'll have to hire someone. They'll probably end up breaking the tiles anyway. Does acetone eat away caulk? I don't know?

PaliBob

It will at least soften up thick caulk. Try hammering a putty knife under the sink rim and pounding UP on on the bottom of the sink bowl.

Will try the acetone tomorrow morning. Have been working on throughout our conversations, and not much success. I'm sure some contractors when remodeling have faced this dilemma but have yet to get feedback. They're probably so busy they can't see straight.

I want to tell you how much I appreciate your responses and advice. I'll let you know what happens.

Warmest Regards

Put some of my leftover acetone and pushed it with my putty knife under the free rim. Wiped up the excess and will try to kkick it's bum tomorrow early a.m. . I am exhausted as of now. But still might try some later. I think I become obsessive or fixated when I can't fix something...lol. Thank you so much for your fast responses and great ideas.
Warm Regards,

Any rust would have nothing to do with adhesion. It's likely just a good bead of caulk. You might try a heat gun along the edge and lifting with a stiff putty knife.

You didn't say what kind of edge you have. It may be a self rimming sink, or one with an metal trim ring. You could also use thin wood, or plywood on the tile as a barrier, and push in a chisel to break the bead loose, while using the heat gun.

HEY just wanted to say a big THANK YOU. I ended up using a putty knife that I heated up with my hairdryer on high and it did the trick.

Congratulations to you and to the cabinetman for the Heat Gun suggestion.
