The title says this is a sealer. The bottle says this is a grout release. Which is it? This is not actually a grout sealer correct?

Hello, If the name on the bottle is UltraCare Grout Release then it is not a sealer, it is a high-performance sacrificial coating that protects the tile or stone surface from grout stains, improves cleanability and reduces the risk of grout haze or film residue when grouting.
