The substrate should be sound, dry, non-dusty, and non-oily. Remove any loose or flaking material. If the stain was an oil based stain, you should sand the wood down to the bare wood (water-based products will not bond with oil-based product coated surfaces). If you are unsure, we do sell sample sizes so you can test for adhesion and appearance.
