Title: Sticker Stain
Post by: Scott G on May 30, 2007, 12:37:09 PM
does anyone know how to get rid of sticker stain on oak timbers?  The stain can not be planed out.

I'm not sure which post to answer...... ::)

I'd try oxalic acid to try to reach the stain. A pic of the stain would be great, and some info on the stickers used to get the stain would help.

Oxalic acid info (http://www.alsnetbiz.com/homeimprovement/oxalic_acid.html)

Won't allow me to upload a picture (files are too big?).  But it is an oak sticker on an oak timber that just sat there a little to long and has visible white/yellow mold.  then after planning it is a darkened area that really sticks out after applying finshing oil

Then the oxalic acid might be your best bet.

See the Help button above for the photo help (great tutorial). Shows how to downsize the photo's to 450 pixels and under 35k file size (resize to 450 first tho). All files start out too big, from my camera anyway.  :)

I see your pics (good job  :) ), but need some interpretation.......(the work is done when you have them in your gallery...just paste them into your message window.  Also, you can go back to a message and modify it, to include your pics and an explanation). :)

The pics look like you tried some bleach or oxalic acid, and managed to get rid of some of the stain. True?

It makes me wonder of there might not be a market for sticker stain. 
Something like "Fairy ladder" or "stack blush".  :P ::) :D

Stack Blush. That's good Tom. But Fairy Ladder, now that's down right poetic. :)

If you haven't already, I would try some bleach - maybe 70% water and 30% bleach (or 50:50).  Scrub with a plastic brush after 5 minutes and then rinse good with water.  If you are worried about the effects of bleach, try it on a small spot first, but I don't think anything bad will come of it - it just might not work though. Call me an optimist, but I think some of what you are seeing might fade with time.  Maybe you could try some benign neglect and give it a couple of weeks w/o doing anything.  :)  I remember obsessing over a few spots like that on my timbers (especially the braces which I crossed up and stacked w/o stickers - planned to be working on them in a few days but a few days turned into a few months...), but now I can't find any of those spots in my house.  Maybe they are covered up with other mistakes now.  :)

"Fairy ladder" or "stack blush", now that's just too funny Tom.   :D  :D

Nothing but planning has been done to that piece.  I will try the bleach and see how that works, but I don't think it will go away with time.  I guy I work with tried that and he still can see it after two years. 

Thank you for your suggestions

Unfortunately, you are probably stuck with it since it is a chemical reaction that has occurred.  Kind of like gray stain from oxidation of some woods like hackberry.  Once it is there, it is not easily reversible.

Nothing but planing? I can understand that for the first pic shown, but how about the 2nd pic? Was some bleach or other chemical used on it? They don't appear to be the same piece.

The photographs, while maybe could be called sticker stain, look to me to be white rot fungus.  It happens when the stack gets wet or when the stickers and the wood are both green.  I'll bet the fungus has entered the board and you won't get it out.  I would throw away the sticker too.

Obviously it was a very wide sticker. (unless that's a closeup shot)
Most stickers I use are only 2" wide and are fully air dried or kiln dried before I put any wood of any value on it.
Never ever stick wet wood with wet stickers......

The bleach lighten the stain but still shows up to much to put it on a show face.  I am going to have to hide it up againts a wall of ceiling. 

But the sticker was 7" x 11" piece of oak that sits on the ground and just wicks moisture from ground, so it is always wet.  I have started to groove the bottom stickers with a chainsaw to help air dry the tops of the stickers. 

Most of the stickers I use are 3x3 or 4x4 dunnage nothing special.  I have come across a company in Ontario that produces grooved stickers.  I have only order a handful to try out and I absolutely love them.  They have completely eliminated the sticker stain problem on those few stacks.  I am in the process of trying to get the approval of replacing all of my stickers with these groozed ones. 

www.breezedried.com  is the website.  At about 2.50 / sticker for a 3x4x48" they are really worth it.

Here is an older thread that will give you some good info on drying stacks and stickers.

Member Flip had some stickers for sale  in the commerce section too.
