Awesome information on this site. My skills would not be nearly as developed if it weren’t for it!! So I have made a few sets of coasters. Made from cherry, oak, and other hard woods. I cant figure out what the best thing to seal them with is? Something that is easy to wipe off and dose not leave a ring… Iv tried mineral oil but condensation from a cold glass will still leave a ring. Its easy to repair though, just reapply. What should I try next? Thanks Jon

I’ve used wipe on poly with good results. It doesn’t build up like brush on so the water doesn’t run off onto the table, but it seems to keep the water rings from setting in.

epoxy based resin. Mix the 2 parts as directed then apply. There is a short pot life after mixed. Heat with a heat gun or a small torch to make it flow. It seals like glass.

I will try the poly and see how it works. Don’t have any epoxy laying around. I will go experiment with tung, Danish, and blo too latter. I was being lazy and looking for a quick answer. Thanks guys!

I would use several coats of oil based poly. I have numerous rings from glasses on my end tables with water based poly, but my dining room table that I finished with about 6 coats of oil based poly I can leave a glass sweating on there all day and there is no ring.
