This is a GREAT clear finish for the Rustoleum Chalked paint on little used furniture like an adult dresser or nightstand, picture frames, baskets, and many other small items which see little or no use either than looking pretty! I am sure it would not/never hold up well on a bathroom vanity countertop with all the moisture. I have used this very often for a clear sealer over chalk paint and I definitely recommend it over the Rustoleum chalk paint, just not for a vanity top.
I totally agree with marine spar varnish, chalk paint is not designed for wet areas the marine spar varnish will give you the most life out of your countertop.
Spar varnish is the best because it is made to be used near water. That is what the boats are coated with. I do not think a chalk paint counter top will last very long in the bathroom. You may want to try a good epoxy or resin.
I was wondering if you could help me with something -- I have an entirely oak kitchen. I know it's the rage now to paint or gel stain cabinets. I've been considering ...

Definitely poly. Better yet--use a marine spar varnish as it is water resistant/water proof.
I am not sure how durable this is going to be for you which is why I suggested the marine spar. I think it will last much much longer this way.
Hi Lisa, you can buy a nice matte clear coat as well, mask off around it and it won't ruin the nice matte look of the chalk paint

Lisa: especially on a countertop --- wax would not hold up!
Definitely poly.
Because of the water present in bathrooms, I'd recommend poly. Several coats.
Best product would be Minwax Helmsman Spar Urethane.

Personally I would only used paint specific for countertops. Should be epoxy based
Hi! Poly will give you more durability. Stay safe!

Hello,
I would make sure the Varnish/Finish you use if water proof otherwise you are going to have to keep re-doing it! Maybe Yacht Varnish - Clear!
Hi Lisa, definitely the marine spar varnish, it's designed for use outdoors, so moisture won't be an issue for it!
Hello Lisa,
You could use clear Contact.
Marine spar varnish would be a good option to go to. Poly is also a good choice.
Vanity tops get a lot of use so going with something very sturdy to keep it dry is best.
Poly is more durable the wax.
