I just bought four bare door slabs, birch veneer. They looked fine when I got them and were very smooth, so I just wiped them off and applied a light layer of boiled linseed oil. The doors looked great and I let them dry overnight. In the morning, I wiped them w/ dry cloths to pick up any residual oil, and applied Arm-R-Seal; they still looked great. This morning, when I went to lightly sand them, I noticed gray flecks all over the doors. You can’t see them until you get fairly close, but they are there, very obviously. Did the linseed oil react somehow with whatever is in the birch? I am mystified. Thanks for any info. john. UPDATED: I dug into the wood w/ my knife, and the specs are deep, nothing superficial that somehow landed on the Arm-R-Seal. All I can then imagine is that something reacted w/ the birch. Any ideas?

Alas! A few woodworkers I know had no positive clue, either, but the company shed light on the subject. A rep said that they see these flecks on the particle board layer under the thin veneer, and suspect that my flecks are those suckers bleeding through. The veneer is very thin (I got residential doors), but they do make a commercial grade door that has a thicker veneer, which will minimize the problem (they did not say “eliminate”). IMO, bag the thin veneer and only make doors that people will (may) be happy with when they finish them! Had I only known….

Have your say...
