Works well and updated my floor to new
I was hesitant this would work but it made my grout look brand new. My original black grout never dried black and so I didn’t like how it looked. Using this one gave me what I was looking for with black on black. One pen, narrow size, was enough for my bathroom floor. Using a damp towel, I was able to wipe the excess off the tiles but not off the grout. It’s just liquid so it’s not going to fill any cracks.

Worked Great & Easy to Use
This product worked great on my black grout ! The black grout was very inconsistent in color and this pen completed the look. The pen was easy to use. I reached out to customer service about getting a new tip for my pen and they were extremely helpful. It was sent in a timely manner with a thank you note signed by Ashley :)

Awesome and Easy Grouting
I liked that it was TRUE BLACK. It went on black & dried black in minutes. Doesnt smell and the single large pen was enough to complete my entire counter top grouting. Couple of "could be better" things. The large tip is very big. (1) If they just included the smaller tip it would be perfect. Suggest scraping away any excess grout before it dries, otherwise you may have to scrub for clean lines. (2) They should include cleaning steps for excess or grout spillage. Its washable, but with some effort. After first attempts , I ended up using the large tip.on its side. It dried true black quickly (photos), but I definitely recommend waiting the 6 hours before getting tiles wet. Bottom line: I am happy with the results. I would buy the smaller tip pen for any tiles smaller than 10x10. My tiles are 12x12 and the tip was even too big for the grout lines. Finished grout looks clean & definitely black. Would recommend.

Great product! Really works!
Love it! The color is vibrant and bold. Works great with my white and grey tiles. My old grout color was starting to look really gross to be honest, and no matter how much I would scrub and sanitize it the stains wouldn’t come out. So I decided to get this product to seal and color them darker so that it wouldn’t be a problem and it’s totally worth it so far. The value is great for the amount you get. I see a lot of people commenting that it doesn’t last very long, but if you’re a frugal, inventive and imaginative you can make it go A LONG way. What I’ve done to extend the life of this pen is to consistently flip the tip over and over once it starts to run low on paint and press down on the tip every time it starts running out. This has extended the life of it so much that I was able to do my entire bathroom tile as well as all of the tile in my entry way. Be creative and you can make the paint go a long way!

Not good for shower
Used this in my shower, unfortunately it comes off when I clean the shower. Looked great, but it just comes right off when I have to clean my shower. Would be great for walls that don't get scrubbed.

Remarkable little grout pen!
Why did you pick this product vs others?: Great product! I used it to give my fireplace tiles a face-lift from dirty white to black. It got the job done and it looks amazing. Ps. I tried a black permanent marker to see if it would have the same effect and it doesn't!

Grout pen
Was super easy to use! 1 pen completed about half of my bathroom tile. I recommend cleaning your tile prior to using. Dries fast and looks great.

Terrible. Don't waste your time or money
Grout Pen Black Tile Paint Marker: Terrible. I applied this on a Friday and wiped it down on a Monday and 75% was on the cloth after one DAMP swipe. Needless to say it all came off with just a cloth and water. You're better off using a sharpie or Crayola marker.

Excellent coverage, makes grout and tiles look new. Such fun to use too. Not sure on longevity but can always touch up again. Would recommend!

Habe den Stift bestellt, da wir in der Dusche (auf dem Boden) Kiesel haben. Die sind zwar toll, aber als kalkhaltiger Stein darf man keinen vernünftigen Reiniger verwenden und so leiden auch die Fugen, heisst irgendwann kalken sie ein wenig zu. Ursprünglich anthrazit hatten sich die Fugen zu einer nicht näher bestimmbaren Farbe entwickelt, heisst, wurden unansehnlich. Da es den Stift LEIDER nicht in anthrazit gibt - komischerweise bei keinem der Hersteller! - fiel die Wahl auf schwarz. ACHTUNG: den Stift gibt es in zwei Größen, heisst Füllmenge UND Breite der Spitze, mit sehr geringem Preisunterschied. Ich hatte zuerst den grossen=dicken Stift. Von dem was rauskommt, gleich. Nur ist die Spitze bei dem dicken Stift auch wesentlich dicker, was vor allem bei feineren Arbeiten, wie bei mir "Malen nach Zahlen zwischen den Kieseln", nicht hilft! Da empfehle ich lieber zwei "dünne" Stifte. Der dicke Stift hat eine Spitzenbreite von ca. 0,5-0,7 cm, der dünne malt zunächst mit ca. 0,2-0,3cm, bis er anfängt auszufransen, dann ein bisschen dicker. Die Stifte sind praktisch, lassen gut mit sich arbeiten. ACHTUNG: Bevor Sie den Stift für den Boden verwenden - vor allem unter der Dusche - vorher alles nochmal gründlich schrubben! Das habe ich vor dem ersten Versuch nicht gemacht und die Farbe ging relativ schnell ab. Nun mit Putzen alles schön neu "verfugt" und es scheint zu halten. Wie lange es an so undankbarer Stelle wie unter der Dusche halten wird, kann ich noch nicht sagen. Bisher macht es einen sehr guten Eindruck. Und auch wenn ein bisschen was hin und wieder nachgerarbeitet werden muss, das ist allemal einfacher, als neu zu fliesen. Empfehlenswert!

Aunque me parece muy caro para la cantidad que trae es muy cómodo de aplicar Ya he encargado más .Lo que no se es la durabilidad con el fregado ya que yo lo he usado para las losas del suelo

Good pen, wide to fit the wide grout lines. Good coverage easy to use. Tip. Have a damp cloth handy to wipe any errors, but you can use a blade to remove also once dry. I would recommend this pen.

Wir haben anthrazitfarbene gosse Fliesen im Eingangsbereich, Gäste-WC und HWR. Die Fugen waren am Anfang anthrazit, nach sehr kurzer Zeit wurden sie immer heller, schliesslich waren sie weiss. Nachdem wir den Fugenstift large schwarz benutzt haben sieht alles aus wie neu. Schwarz wird in der Fuge zu anthrazit. Auch nach mehrmaligen Wischen gibt es keine Veränderung. Wir sind begeistert. Ist absolut zu empfehlen.
