Review: Transformed my floor! - See photo for before and after!!!! These pens are amazing!! The 2 pens did a very large kitchen space, so easy to use! Dries quickly and had no problems from mopping the floors etc. highly recommend
Review: Great product to bring new lease of life to old grout - Easy to apply and brought a new lease of life to our tiles. We were really surprised just how fresh and modern the grout pen made them look - a great way to overhaul a bathroom without re tiling or re grouting. Only thing would be to maybe make the nib silicone or a more durable material. The ink goes far but the nib wears down pretty quickly meaning we needed several pens in the end and not just the one claimed int the advert - but as they are so inexpensive and the result was great that wasn’t a huge bother. Great overall results that seem to last well so far. Did the floor tiles too with a lighter grey with similar results.

## Questions & Answers

**Q: The Grout Pen I received has a dry white tip, is it broken or did I receive the wrong colour?**
A: Tips need to be primed before use, all brand-new Grout Pens have a dry white tip until they are activated.

**Q: The tip of my Grout Pen fell out or is worn down, is my pen broken?**
A: Tips are designed to be removable so when a tip becomes worn or damaged it can be taken out and flipped over. If the tip falls out do not worry, simply put it back in and keep working.

**Q: Do I need to press down hard while moving the pen along the grout lines?**
A: Pressing hard will damage the tip. It's better to prime the pen by pressing up and down until the ink flows to the tip. Once the tip is fully saturated, lightly move the pen across the grout line.

**Q: The colour of the pen cap is not exactly the colour I want**
A: The Grout Pen colour chart is a good representation, please keep in mind that computer screens can display slightly different colour spectrums, it is recommended to do a small test area first if you are not sure about the colour.

### ⭐⭐⭐⭐⭐ Amazing Transformation
*by M***N on 14 May 2025*

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.
