I've got a metal sink that has a thin protruding caulk line around it
on top of the corian countertop. I'm not there right now but I did
see it and I'd say it's around 1/8" or less bead around sink whick
lays on top of countertop. Part of the caulking is kinda rough or
scraped up while the other parts are still smooth. It's not leaking
any water underneath but for the future, what's the best way to try to
remove the roughed up portion and recaulk it? I'd probably try to
use my finger to run the new caulking around. I'm thinking it's
probably best to remove the old as much as possible before recaulking.
I don't mean that I'd lift the sink but rather try to remove as much
caulking with the sink in place. If I do remove the old stuff and
being it's like 1/8" protruding, what's the best way to remove it
while not damaging the countertop. I know Corian is resilient but I
really don't want to scape it any more than necessary? I do not know
how hard the old caulking is but as I recall I touched it and it felt
stiff but I didn't put my fingernail into it. If it matters this sink
installation and house is about 6 years old.
I have no idea what was used. If it was truly caulk, I would start with
a razor blade scraper. If it was some form of epoxy, it may be much
harder to cut and to remove. I doubt that it is epoxy because it is
messed up. Sounds like someone got into the caulk with the wrong type
of scrubber or wrong chemical.
Again, I would start out with a razor blade scraper or really sharp
carpenter's wood chisel.
