Topic tags/keywords: wood finish

Hi everyone… First post here very exciting. I’ve just finished building this table. I’ve sanded it and was about to finish it with watco Danish oil. However, I can’t stop noticing this yellow discoloration on one of the table top boards… I’m sure you can see it and I promise it is much worse in person. I’ve tried aggressively sanding it and can’t seem to get anyway. I experimented with the rest of that board with the Danish oil and it just makes the yellow stick out more. Aside from painting the table does anyone have any suggestions for getting rid of or minimizing
the yellow? Also does anyone know why it’s yellow??

Thanks.

Ben

I would replace the board. It is just part of the board. Some are lighter, some darker, some have a different color. I have my own trees cut at a sawmill, so I know they are from the same tree, but there is still different coloration in some trees..

Replace the board, there is a lot of variation in coloration between trees.

I agree, replace the board if it really bothers you or if you use Watco try one of the colors they offer which should make all the boards the same. For some wood the natural color will eventually change as it ages and become more uniform.

Where do you plan to use the table? If it is outside in the elements I do not recommend using Watco oil. There are better products for that.

Thanks everyone. Not sure if I’m going to have the willpower to change it. I’m using it indoors hence the watco.

If you don’t, you will be sorry every time you look at it.

Ha! Yeah it bugs the crap out of me. It was screwed and glued on. Glued on each of the bottom cross supports and at the two ends. Not sure if I’d be able to get it off. What do yoh think?

Before I tore it apart, I’d try to lighten it. Start with plain old bleach. Then, if that doesn’t give you the results you want, go with some oxalic acid.

Also, for bleaching, pool shock is a good choice because you can mix it to whatever concentration you want.

You can test it on the spare part of the board you mentioned.

Tries the bleach… Didn’t make any difference at all. Im not sure the oxalic acid will work bc it’s not like weathering… It’s just a different color. I dunno. Anyone have experience trying to separate something glued on like that?

Personally on something like that I would go the other way and stain it. General Finishes “New Pine” gel stain is a light yellowish stain that tries to replicate what pine does after a while in the sun where it gets a mellow yellow color. Could try it out on a scrap. Then if its close do 1 coat on that board and 2 light coats on the rest.

Hmm that’s fair. I think I’m going to remove it. Does anyone have any ideas as to the best ways to do this? I’m thinking of just a hammer and chisel but open to ideas.

Are u going to stain the table when ur done? If so I’d say the color of the board will blend in much better so I’d leave it. Another thing u might try is to set the whole table outside on a sunny day. Seem like the sun changes the color of pine pretty fast so it might blend the other boards to match.
If u have to remove it I’d suggest a oscillating tool to cut that board at the glue joints. U might b able to steam it depending on what glue u used but u run the risk of that effecting the glue joints around it.
