Easy application, instant impact!
These grout pens are the best way to transform your tiles! 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.

Great grout refurbisher
I've already used these, follow instructions regarding cleaning of grout and it's easy to use, covers really well and lasts, even when using a steam mop, usually re paint around every 12 months, I have the black cus I've got black grout, can't comment on other colours.

Grout pen
Works good on flat surfaces but find when your working down the wall tiles you have to stop and shake it every 30 seconds otherwise it runs dry so it’s abit difficult to use in that sense. But would recommend as once it’s on it looks great and lasts years

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.

Does what it says!
So easy to use and loads in the pen. My black grout had gone white with limescale and looked naff. I did all round my bath/shower and around the sink all in one pen so have one spare! Agree bit fiddly when going across tiles (left to right) but you just have to tilt pen nib downwards when marking grout. The up and down was easy, although I just drew upwards, i found when going down it made the nib of the pen fuzzy. When it got sparse i just gave the pen a few shakes and depressed on the nib. I did not have any issues with drips or the nib overflowing with paint/ink. Result was amazing. Looks just like it did when i first tiled it! Whole process was about 30-45 mins. Left overnight to dry. Totally revamped my bathroom. Definitely recommend.

Just awful!
What a waste of money and time and energy. It’s awful to use and you cannot get a steady line. Then as soon as tiles get wet (obvious they will in a kitchen or bathroom) it comes off. In the end we had to scrub all the black pen off the grout and re do it on white! Wasted 3 hours and £7, not happy!

This pen was excellent. My black grout was faded. The pen was extremely easy to use, easy to wipe off. The nib just flowed along the grout lines with ease. No oder. I bought the double pack but didn't need the second pen. The whole thing was much fun and had such great results, I wish I had more to do!

So wie beschrieben

This completely rejuvenated my dated wall tiles when I redid my floor and shower. You can’t really mash it, because the grout will chew up the end of the pen a bit, but it works great and wipes off the tile easily if you get any outside the line. It’s best to keep the pen angled downward, so change your hand position if you’re working on a wall nearing the floor. I really like this stuff and absolutely would recommend. Clean the grout first though! Especially if it’s in a kitchen where the grout could be greasy. Fun D.I.Y toy, can change the whole vibe with very minimal effort.
