Should grout be scraped before a grout color sealer application?

Q. Should grout be scraped before a grout color sealer application? I want to put color sealer on top of grout that has already been sealed. Is it necessary to first scrape the clear sealer off of the grout? 

A. There is a quick test you can do to determine whether the grout color sealer will properly absorb and adhere to the grout. Apply the grout color sealer to a small area in an inconspicuous spot. Let it cure for 24 hours. Then, take a piece of tape, press it firmly down on the test area, and then rip it off. If the color does not appear on the tape, then the grout will take the grout color sealer. If grout color sealer appears on the tape, the floor will need to be stripped. Be careful to select a floor stripper that is appropriate for your floor type to avoid damage. Once the grout lines are thoroughly stripped, cleaned, and dry, the grout color sealer should adhere. Do not scrape the grout.
