New-refinisher

Haha - the consequences of not doing enough research!

Im working on my first refinishing project and made a very dumb mistake. I’m used to painting old furniture, not staining. I am refinishing a very solid kitchen table and applied Varathane Poly + Stain and didn’t wipe the excess. Just brushed it on. I know... So now the poly + stain is dried and very thick. I can see wood grain in some places but not overall. It looks like paint at this point. What can I use to thin it out but not strip completely? I tried mineral spirits but I think because there is poly in the mixture, it’s not working...
