Topic tags/keywords: question wood oak

I’m finishing this old oak log from a barn built in the early 1900’s. It had some wood rot I chiseled most of it out and have been sanding a lot!! But no matter how much I sand I still get flakes breaking off. So my first question is do I need to keep sanding until it stops or will putting a poly or a lacquer stop it from flaking. 2nd question there are some soft spots in the wood I just can’t get to with the tools I have would a wood hardener help with that at all. And my final question is can you spray a poly through a spray gun I’ve seen lacquer sprayed so just wondering. Plus any tips would be greatly apriciated.

You can soak the punky areas with CA glue which a move done by a lot of turners. I would stop sanding personally. I don’t think youre ever going to solidify something that old and worn.

My goal would be to firm up any punky areas with wood hardener or CA glue and knock off any heavy ridges to prep the surface for finish. Poly or lacquer should firm it up quite a bit so youre not losing flakes but I wouldn’t ever expect 100% on a piece like that. Eventually youre going to have to say enough is enough ya know.

You can definitely spray poly through a gun. I do believe water based is preferred but ill defer to others with more knowledge on it.

Kinda what I was thinking. Thank you for the advise I’ll look into CA glue. This project is definitely more difficult than I expected but I couldn’t just let them turn it into fire wood.

“Git Rot” is an epoxy made for stabilizing and hardening punky wood. I assume it’s still made—if not, there should be substitutes available. Supposedly it is absorbed into the punky wood via capillary acttion. It’s quite thin to help in this, but like any epoxy, it will run right out of any holes that go clear through.

Just checked. You can get it from Amazon. I hope you can stand the fact it isn’t cheap.
