Review on 🛡️ The Floor Guys' Grout & Granite Penetrating Sealer: Effective on Marble, Travertine, Limestone, Slate. Shields Against Water and Oil Based Stains. Specifically for Flooring and Showers. 1 Quart Size by Kyle Wesener

Lasted a month or two after installing the kitchen floor before grouting. Wife complains so I used that. Was hoping it would work otherwise you'd have double gripe for both being idle and using a bad product. And so last night the woman "accidentally" splashed SPAGHETTI SAUCE directly into the joint. Tension mounted as she wiped them away with a damp kitchen towel. Did I pass the male test? Or would I always hang my head in shame? Wiped right away, no stains. I applied with 1/2" art brushes; bought 20 packs cheap here and just threw them away. Won't show up on tile once dry so no excess to wipe off unless it's a big blob. Two coats applied a day apart; first soak and heavy, then light cleaner.
