I bought an antique wooden cabinet with a veneer finish and a gorgeous Talavera pottery Mexican vessel sink, and I hope to combine the two to create a unique bathroom vanity. My brother is all set to drill a hole in the top of the cabinet to put the plumbing.
But here's the problem: he told me I need to waterproof the top of the cabinet or I'll ruin the wood veneer. Any ideas on what kind of product would best do the job? He thought maybe some type of marine varnish.
