How do I seal a soapstone sink (outdoors)?
I am in the process of restoring a soapstone sink that has been on the property 50+ years and painted numerous times. I am enclosing the base with reclaimed wood and the sink is almost ready to seal it. What product or steps should be used to enhance the natural beauty of the sink and protect it from the elements. Thanks!

hi - i looked up sealing soapstone and this is what i found -
"Soapstone oil is not sealing or protecting the stone, it is only “speeding up” the natural darkening process. Soapstone is non-porous and, unlike marble and granite, does not need to be sealed."
Maybe use turtle wax on it if you want water beading?
I agree with Kate. It does not need to be sealed but does oxidize from minerals in the stone. Mineral oil, paste wax would protect it and slow down the oxidation process. Anything else , like poly, varnish, would just float on the surface crack and flake or peel off.

You could use a penetrating stone sealer that would be used on stone tile. According to the previous post, soapstone is non-porous however a stone sealer would not hurt it. You can even apply the sealer over glass tile when it's mixed media tile and glass is non-porous.

The vanity top in my guest bath appears to be soapstone - but I’m not sure after reading the above, what it is?. I realized shortly after we moved in that it was VERY porous: I spilled a few drops of Neutrogena shampoo and within a half hour, there was a stain I still cannot remove. Recently, I was cleaning the drain - I use vinegar and baking soda - and drops of vinegar left permanent marks that appeared to eat the finish.
