I’m evidently on a hot-glue kick lately. This bath mat requires just
three materials: shelf liner, hot glue, and 175 wine corks.
For the record, I’m against sealing my wine cork bath mat.
I mean, corks are exposed to the moisture of wine for decades and seem
to hold up fine, right? But several readers insisted cork needed to be
sealed, so I did some research on sealing cork. It seems the best option
is probably a sealant that’s made for protecting the cork foot beds of
sandals such as
Birkenstocks. I bought a 2oz. jar of Sure Foot’s Cork Renew for $5 at my local shoe repair shop.
Today I started applying the sealant one row at a time. I didn’t like
the glossy, tacky feel of the sealant, so I was hesitant to keep going.
My compromise: I painted the cork sealant on only half the bath mat,
and I’ll compare the results in a few weeks. After letting it dry for a
day, I’ll start the test on Monday and keep you posted with the results
UPDATE: I recently tossed out the bathmat
because the sealed side got too gross (with lint and debris sticking to
it) and because the corks started popping off more frequently. No sign
of mold. It lasted 18 months. Not bad. I plan to make another (unsealed)
cork bath mat with better glue soon.
CONCLUSION: Unless you are in the habit of creating a
swamp of your bathroom floor every time you shower (and you know who
you are), unsealed wine cork bath mats can be expected to hold up as
well as most store-bought bath mats. Because common sense isn’t as
common as one might hope, I’ve put together a mini tutorial for keeping
your bathroom floor dry, and thus lengthening the life of your bath mat.
