Amazing Transformation
These grout pens are great to use and really transform the appearance of tiles, whether brightening faded white grout, or changing the colour completely. You need to press the nib down to get the paint to flow, which you'll find yourself repeating frequently. Don't press too hard, as the nib eventually works its way inside the pen, so the less pressing the better. You can go at grout completely free hand, give it 5 mins or so to dry, then wipe over with a dry, preferably textured/micro-fiber cloth, to remove any excess on the tiles themselves. Don't worry, it comes off the tiles very easily. We used dark grey to make the 1/3 brick finish of our white tiles stand out, and we're really pleased with the results. I've bought another pen to keep as spare and use to touch up a few areas that were proving tricky to reach as the original pens ran out. The only down side is that painting the grout a darker colour shows you if/where it wasn't grouted very neatly to begin with!! I had to sand a few areas first to get the lines looking neat.

Results of the dark gray
The pen works well The finish looks brilliant, but definitely no where near up to 60 linear metres like that say, I've not did a complete measure yea. I've got a much bigger project next to do will the light gray so I'll keep you up dated on that one. The big one will be how long will it last. Lastly for the coverage lve got so far l think it's a bit expensive,but l do recommend the rainbow grout pen every one got the own opinion.
