problems of discoloration of fumigated larch veneer after sanding4/5
Guys need your suggestion as early as possible. i am facing problem in discoloration of fumigated larch veneer after sanding. if any one worked on such problem or having any idea please shear. problem is shown in picture also....plz download and then see
Does the color change on the fumigated piece have something to do with your color scheme or is the fumigation done just to kill off bugs.
Reason I ask...if you sand a bleached piece of wood too aggressively; you can sand right through the bleaching effect.
Is it possible that you sanded the fumigated piece too aggressively, and sanded back to the original color of the wood.
It could be the sander itself....try a simple hand sand with 320. Does the fumigation process make the wood rough...do you sand the veneer prior to fumigating it.
I had the same issue with fumed qtr. fig eucalyptus. It appears it as though the color lightens up, but as soon as you hit it with a clear finish the color comes back. I am assuming it will be clear. Try a small piece and see what happens, I'm sure you'll see some positive results. Also, I wouldn't go any higher than a 180 grit before shooting it.
