Hi. I started making guitars and basses myself, but the problem is that I'm Korean and I live in Korea where there's not a really wood worker's heaven. I couldn't even find a wood store that deals birdseye maple. Anyway, I bought some Buckeye burl from overseas and I thought I would be able to get Minwax wood hardener to stabilize it, but there's no company where deals that. Not even other wood hardeners from other companies. But while I was google researching, I found out that the concrete hardener is commonly used in the construction site in Korea. You know, to harden the floor for the heavy vehicles wouldn't damage it. Then I thought, it must be just another chemical to soak into the small holes in the concrete and gets hardened overtime, it might work on wood! But I don't want to ruin 100 dollars pieces of wood to see if it works. Is there anyone who tried this? Concrete hardener on wood?
