Re-Caulking a Sink

johnc777February 6, 2013

I have a typical cast iron top mount sink on a laminate countertop. The caulk around it seems to be deteriorating and if I look under the sink I can see some discoloration in the particle board in spots. I guess that means water is getting under there. I'm wondering if it would be better to pull the sink completely out, clean up any old caulk, and apply a bead of fresh silicone (that's what I should be using, right)?

Or can I get away with just cleaning up what's visible and maybe running something like a utility knife blade or scraper under the rim of the sink to remove what I can. Then apply a fresh bead of caulk along the edge???

You'll have a neater and probably better sealed job if you pull the sink, clean it up and reinstall

Just remember that a cast iron sink is very heavy.

I kinda figured that pulling the sink would be better. I'm a little worried about the weight too. Not that I can't pick it up but rather setting it back down and making a mess of the caulk job.
