ᐅ Laminated beech wood boards show very different results after oiling.

Hello, I’m a bit confused... About four weeks ago, I bought laminated beech boards for the shelves of our room divider at the hardware store. At first, I only bought five pieces, because the rest had some defects. The boards were properly sanded and then treated several times with linseed oil. The result was perfect... wonderful color and surface.

This week, I picked up more laminated beech boards from the same hardware store (same manufacturer, again beech). I followed exactly the same steps as with the first boards. But the result... a disaster... what is this??? The boards now look completely different!! I didn’t even know that beech could darken this much... see the result for yourself. What should I make of this? Is this normal??? Best regards, Steffi33

The oil was very fresh. We have a paint manufacturer in town who also sells linseed oil at their factory outlet. Earlier, I oiled a leftover piece from each of the two wood batches again… the effect is the same as before – one piece is light brown, the other deep dark brown. Best regards, Steffi33

This just goes to show: oil is not all the same.

There is a misunderstanding here. The oil used was always the same (the same can)... It actually depends on the wood. It would be more accurate to say "beech wood is not the same as beech wood."

I actually find the very light first option quite surprising. I usually know oiled beech wood to be darker. Even within the panels, you have different shades on the individual lamellae. Depending on how the panel is assembled, you can get very different variations. Of course, you can hope to find wood that happens to react less darkly to the oil. It might be better to tint the oil slightly to avoid everything turning too dark. Alternatively, you could use oil with light pigments.

If you prefer a lighter look, go for birch or maple flooring.
And visit a reputable timber supplier or joiner who can cut your floorboards from a large panel. Ideally, with continuous lamellae. This way, you’ll have a better chance of achieving uniform shades.
