Bought three sets and tested on beige tiles. The paint dries quickly and is easy to use, but results depend on the tile and the size of the crack. To me, our tile is a mix of colors, so the beige filled the crack with a gummy substance, but it's slightly noticeable afterward. In the first photo, the beige doesn't blend and doesn't give the desired effect. Blending is the way to go as the tile is a variation of the colors I mixed with the wet paint to match as the color changes. The paint dries quickly so I used styrofoam and just a smear of white and beige. Also use a razor blade to scrape off excess paint. Although the crack is slightly visible, it's much better than before and cheaper than ripping floors apart. Watch the video for an example.
