How do I remove cured epoxy grout film from the face of tiles?
Use a neutral pH detergent/water solution (electric dishwasher detergent works very well) along with a sponge and extra LATICRETE SpectraLOCK PRO Grout Part C powder. Apply the soap/water solution to the face of the tile in the affectd area(s) and then sprinkle the LATICRETE SPectraLOCK PRO Grout Part C powder onto the wet area. Use the sponge to scrub the surface with some pressure to “abrade” the haze off of the tile. Conduct a test area in an inconspicuous area to verify suitability of this method for your tile or stone and to determine results.
