Hi Sarah,AFM safecoat clear penetrating oil performs best when used on its own and is ideal for unfinished butcher block countertops since it's a food grade product.Since we are not familiar with the product already covering your surface we can't say for sure whether our product would properly bond over it.This product needs to be able to penetrate the surface which can be difficult when another product is blocking application.If the current stain is a well dried, oil-based stain I would recommend getting a test sample of our product, and trying it in an inconspicuous area to see how well it bonds.
