Correction: I should have said: "hold the scraper at an acute angle," meaning maybe 10-15 degrees from being parallel with the surface. Just experiment and you'll find the right angle. The lacquer thinner may be necessary in any case if the spray has gotten into microscopic pores/pits in the marble. Just go easy with these steps and it should work out fine.

Thank you! I'm just seeing your post that says "correction" - was there one before that?

No...I just wanted to make clear that I originally wrote "oblique angle" (it was late at night when I posted :-) ), and should have written "acute angle." I thought I would do a second post, rather than just edit my first one since I didn't know if you had already read it. Doing a second post was a way to get your attention again if you had already read my first post and gone away :-).

Thank you! So try just the plastic scraper first, and then a lacquer thinner if needed? And lacquer thinner is safe on marble tile? Thank you!

Does marble get sealed? Lacquer thinner will eat through anything.

laurenjean and paintguy-

It''s true that lacquer thinner is a powerful solvent, but

1: If the marble is sealed, all the overspray should be on top of the sealer and the razor blade should remove all of it overspray, making a wipe with lacquer thinner unnecessary.

2. If there is no sealer, a wipe with lacquer thinner shouldn't hurt marble. (Marble is typically damaged by acid compounds, like lemon juice, or alkalis, like drain cleaner. If one has concerns, you could test the thinner on a marble scrap or a small unnoticeable area. However, if it's real marble, and not some man-made composite, there should not be an issue.)

3, Sealer can be reapplied in any case...it's not like trying to match a stain.

Thank you! It's new construction and I don't think they sealed the marble tile backsplash. I think we'll try to tackle this tonight! Thanks for all the advice.
