In this clip we're going to talk about raised grain, which is a phenomenon your going to have to deal with with you, when you're staining wood. Basically when you apply moisture to the surface of a piece of wood, the grains at the surface of the wood are going to raise up a little bit. Now you can, you can minimize this problem by first conditioning the wood as we talked about earlier with the, with the way it deals with the penetration of the stain, but it also, conditioning the wood also minimizes the raising of the grain. Let's take a close look and see if we can see some raised grain on the surface of this Birch plywood. It's a very subtle effect, it's very difficult to see, but you can definitely feel it as you run your fingertips over the surface of the wood. You can feel the sort of bristliness of the grain.
