I am making some trim board. We had some ash wood milled and kiln dried for this. I primed it with a trim primer (it is very thick and white) and already put on 3 coats of trim enamel paint (water based). On some of the board, where there was a variety of colors in the grain, the lighter areas are bleeding through the paint and show up as yellow. My question is two-fold:
- What can I do now to fix this?
- What can I do better for the next pieces to prevent this from happening? Since we have to paint this in the house, it would be great if anything oil/solvent-based can be avoided
