Review on Revive & Waterproof with Grout Pen Tile Paint Marker: Yellow Cream, Narrow 5mm Tip (7mL) by Anil Jaimes

***upgrade. It will not take long. The painted mortar on the floor came up immediately. If water is spilled on the floor, the paint will peel off even after a few weeks. I was very sad after painting all the grout on the bathroom floor. money down the drain. It's like the markers we used to decorate folders at school. Shake and inflate the tip to fill before and during use. Apply light pressure. Come back if you have to. I tiled the entire back wall of my shower in about 15 minutes. The tip of my pen is fine. As long as you don't apply excessive pressure, the tip will not wear out. I will be back to order more to grout the tiles in the kitchen. Very easy to use. Simply wipe tiles with a damp cloth when they get dirty.
