TheFirePoppy Posted January 16, 2018 Report Share Posted January 16, 2018 Hi folks, I'm a total newbie. I cut a cookie from a fallen oak tree at work to make a sign/keepsake for my sister's wedding. She plans to keep it on her doorstep as a welcome sign, so it will be exposed to weather changes (though covered). After some research, I'm tempted to go for CAB-laquer for the finish, but am wondering if anyone has a different opinion on that? Also, if I do go with CAB-laquer, is there a sealer or something else I should put on it first? (Already did a pentacryl soak before sanding and whatnot, and will woodburn their family name into it this week - also open to advice on that!) Photo of the slab attached. Thank you so much for your expertise and guidance! Cheers! Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted January 16, 2018 Report Share Posted January 16, 2018 Either an outdoor oil product, such as a deck sealer, or spar varnish. You need something flexible, that cookie will move a lot. Judging by the pic, it is fresh cut and green. Prepare to "Release the Crackin'!"

Chet Posted January 16, 2018 Report Share Posted January 16, 2018 Welcome to the forums. If that is still green then it is definitely going to move and in all probability crack. I would probably use deck sealer like mentioned above, and re-apply every so often at least until it settles down. Quote Link to comment Share on other sites More sharing options...
RichardA Posted January 16, 2018 Report Share Posted January 16, 2018 And then an epoxy pour all over it. Quote Link to comment Share on other sites More sharing options...
drzaius Posted January 16, 2018 Report Share Posted January 16, 2018 That's a very good looking chunk of oak. The pentacryl should help mitigate the shrinkage, but I have no experience with it myself. As for finish, I'd encourage you to use something that doesn't impart a high gloss, cause that'll make it look more like plastic than wood.
