Review on 🔲 Waterproof Dark Grey Grout Pen: Tile Colorant and Sealer Marker - Dark Grey, Narrow 5mm Tip (7mL) by Leroy Jacobs

Loved it! You changed my kitchen. When our contractor installed the backsplash in our kitchen, he used an almost gray grout that was so light it looked white. You couldn't even tell we had tiles there. Bought it in dark gray and it worked great! Gave us the contrast we needed. Tip: you will get it in a tile, there is no way to avoid it. Just leave it on for a while and come back 20 minutes later with a damp rag and it will instantly wipe the tile but not the grout (if you try sooner you'll wipe the grout). I left some overnight and had no trouble taking them off. Highly recommended. I wish I had sooner.
