## 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.

### ⭐⭐⭐⭐⭐ Great results 👍
*by D***Y on 23 October 2025*

Does what it says. Easy to use and good coverage.

### ⭐⭐⭐⭐ Easy to use although be aware it is a blue-grey colour
*by D***X on 21 June 2024*

I like these grout pens. They do a great job of refreshing grout. Used lightly, one just draws lines along the grout. Any overspill on a tile can be wiped off. Some people think the nib is too soft, falls out etc. I found using in lightly and slowy means I have no issue with the nib. I found this grey pen to leave a blue-grey colour, not light grey. This was fine for me, but may not suit everyone.
