Rainbow Chalk Markers Limited Grout Pen Black Tile Paint Waterproof Tile Grout Colorant and Sealer Pen - Black Narrow 5mm, 2 Pack with Extra Tips (7mL)

These were crap and extremely hard to use on grout lines, I ended up repainting them as it did not look good

I’m on track to use 6 pens to cover a large area (kitchen, dining & living room) Eventually they will dry up obviously but useful volume of each pen is satisfactory. Easy application, but if you want a good result be prepared to lay on the floor and go slow. It’s looking great imo and am having fun doing it little by little. We clean these floors without much water and cleanser, so am not afraid of washing it off, they seem pretty permanent. For me it’s a 5 star product.

Best grout pens around! I moved into my apartment and it was all white, I thought I would have a go at a grout pen and seeing if I could make it look better. These are so worth the money as the transformation of my bathroom is amazing! The coverage is great and they are very easy to use. I used these in January and it still looks the same so the pen liquid is very durable. It takes around 2 minutes to dry. The pens are the size shown on the advert, however one pen lasts a long time!

Kann ich nur empfehlen, Fugen aufgewertet und hält jetzt seit 2 Jahren

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.
