Review: The before and after speaks for itself! - Easy to use. True to colour. The grout in our bathroom was very dirty and discoloured. Needed a good deep clean, after a scrub and using this pen our bathroom looks brand new and sparkling! We have floor to wall tiles and I managed to do about 90% of the room before the pen ran out. Have purchased another! Very impressed :)
Review: Great looks lovely and clean - Brilliant product, definitely goes a lot further than I thought it would. I bought these to try and revive a wet room floor, I ordered two just to try thinking I’d need at least four if it looked ok, two did the whole shower and the rest of the en-suite floor. The shower area is mosaic so much more grout. Nice paper shade of grey so a definite grey but looks nice and clean rather than a dirty white look. Easy to use, the big perhaps a little thick and the only thing is it wears away eventually so don’t be too rough with it and don’t get it wet at all as one of mine wore away that i couldn’t use it anymore, I think because the original grout was quite gritty this happened, otherwise I’m sure it would be fine. Easy to use and didn’t need to shake it every five seconds it lasted a long time. Left overnight then mopped and showered today seems perfectly fine. Can’t comment on how long it lasts or anything yet but a cheap way of tidying up the shower and I have done the wall tiles with the white ones a year ago and it still looks good as new so hopefully this will last the same and only need done every few years. Much easier than taking out old grout and making a real mess. All in all very happy

## 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.

### ⭐⭐⭐⭐⭐ Brilliant!
*by C***Y on 13 August 2024*

These grouting pens are a godsend! I've been using them for years and transformed many a tile job with them. Sister had just got an extension fitted and new kitchen but as part of the old kitchen tiles were still left in she was looking at replacing them...much more costly than a grout pen! I suggested using the grout pen, which she'd never heard of before...In just over an hour the job was done and they looked like they'd just been newly fitted. They went from a dirty old white grout on white subway tiles to a lovely clean and new looking tile job...money and time saved...and also kept rubbish out of the landfill too which we should all be doing where we can! Just make sure to shake the pen ever now and then during application for ease of use.
