I'm trying to apply Minwax Polyshades espresso stain after having applied a coat of Minwax Polyshades pecan to solid pine wood. I pre-conditioned the wood and applied two coats of the pecan. I'm using an old t-shirt to apply the stain as I find it works best to prevent blotching and air bubbles.
Now, I'm trying to darken the wood tone a bit in general but especially along the edges and the knots. It doesn't seem to be working for some reason, and I'm wondering if it's because Minwax Polyshades includes the polyurethane finish and so my third coat of espresso stain is not able to adhere to the wood.
Do I need to apply multiple stains of espresso? Or perhaps sand more before applying the espresso? Or is this all I can get with a product like Polyshades that includes the polyurethane finish?
Thanks for any help!
