I have used in both bathroom and kitchen on white grout and they’re fantastic. Two pens were more than enough for the kitchen. For my shower tiles, approx 6 Sam I used 4. Not because the ink ran out, but because the nib starts to blunt and the drawing line becomes thicker. To keep the lines consistent I switch pens more regularly. Long lasting as well. The colour is black, as for it being waterproof it is to an extent. The kitchen area hasn’t required a touch up in 18 months. The bathroom, as it has shower watering hitting and more abrasive cleaner used does start to come off but a quick touch up every 6 months works well. Brilliant value for money and so much easier than re grouting. Dries quicker. Great coverage. Highly recommend. Review: Really Effective - These are great, bought white to touch up the Kitchen & black to Revamp the Bathroom. After reading other Reviews about the nib, I suggest running the Pen along the grout with light Pressure to protect the nib for longer use. I was able to use the whole Pen. The black is a bit more tricky & took a little more Patience, I used wipes as I went to tidy up. Worth the effort & now just need to see how it fairs with Water when using the Shower. Both look Fab & like they’ve been freshly Grouted. ## Features - Contains a mixture of 5-Chlor-2-methyl-2H-isothiazol-3-on und 2-Methyl-2H-isothiazol-3-on (3:1) (CIT/MIT).

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy application, instant impact! *by J***. on 8 November 2025* These grout pens are the best way to transform your tiles!
