All right, I tried this on a scrap piece (of thin birch ply). I sanded it to a very smooth finish, then masked it with painters tape - pressing it down really tightly along the edge. I then rubbed the stain in (Wattle colourwood pigmented stain) with a cloth as per instructions. An hour later I removed the tape and the line was nice and straight with no bleed!
So, at least this combination works ok with no bleeding: Birch ply + smooth sanding + painters tape + Wattle pigmented stain. |
