We just sanded and finished an angeline wood floor 10 inch -22 inch planks. The homeowner installed flooring. The floor is full of sticker stain, we were aware it was there and assumed (i know) that the homeowner was aware that it does not come out. My question is has anyone finished an angeline floor and will the stains diminish at all over time. Finish was emulsion and street shoe.My thought is they are there to stay.

You think correctly, I am afraid. It is extremely unlikely that the sticker stain will fade over time. Although the floor may darken a bit, so too will the stain.
