We bought a house a month ago and just noticed water discoloration marks developing around the kitchen faucet (undermount sink). What do I need to do to protect the wood? It was a flipped house so it is new, and I have no idea what they used to seal the wood. I have tried to research this question, but I'm unclear about if I need to do anything to remediate whatever damage may have already happened, or how to proceed if I don't know what kind of sealant or protector was already used. I do not see any caulk around the base of the faucet. Thank you!
Wood and an undermount sink is going to take regular maintenance. That maintenance can be as simple as wiping up any spills promptly, and applying mineral oil every week or so, or you can go whole-hog into trying to convert your wood countertops into plastic ones with coats of polyurethane.
Friends who made the choice just do the regular oiling, perhaps some wax occasionally.
