Hello All .. hope you can help. I stained a new (I'm pretty sure it's pine) garden gate with a medium brown wood stain. I have to re-do it every two years because the knots tend to bleed. I scrape off the dried sap first. Since it needs doing again, I'm thinking of rubbing down the knotted areas and applying a few coats of knotting solution before I stain it again. I'm using black this time. My problem is that I don't know if the knotting solution will stop the stain from setting in the wood. Any comments would help a lot. Thanks in advance.
