Although we use the most premium and hard wearing Baltic Birch available, you’ll still find several football, oval, or irregular shaped patches in either side of Baltic birch. Even the highest grade of Baltic birch allows for patches. While at first glance they might seem unsightly, they’re indeed correcting a worse problem that you wouldn’t like any better – such as knots or discoloration. Fortunately, patches are color matched, so they blend as best as they can to the surrounding areas.
