Great product to bring new lease of life to old grout
Easy to apply and brought a new lease of life to our tiles. We were really surprised just how fresh and modern the grout pen made them look - a great way to overhaul a bathroom without re tiling or re grouting. Only thing would be to maybe make the nib silicone or a more durable material. The ink goes far but the nib wears down pretty quickly meaning we needed several pens in the end and not just the one claimed int the advert - but as they are so inexpensive and the result was great that wasn’t a huge bother. Great overall results that seem to last well so far. Did the floor tiles too with a lighter grey with similar results.

Amazing Transformation
These grout pens are great to use and really transform the appearance of tiles, whether brightening faded white grout, or changing the colour completely. You need to press the nib down to get the paint to flow, which you'll find yourself repeating frequently. Don't press too hard, as the nib eventually works its way inside the pen, so the less pressing the better. You can go at grout completely free hand, give it 5 mins or so to dry, then wipe over with a dry, preferably textured/micro-fiber cloth, to remove any excess on the tiles themselves. Don't worry, it comes off the tiles very easily. We used dark grey to make the 1/3 brick finish of our white tiles stand out, and we're really pleased with the results. I've bought another pen to keep as spare and use to touch up a few areas that were proving tricky to reach as the original pens ran out. The only down side is that painting the grout a darker colour shows you if/where it wasn't grouted very neatly to begin with!! I had to sand a few areas first to get the lines looking neat.

Good value for the price but pen is for a one use only as the tip doesn't last
Used this on my kitchen floor. For me the thickness of the pen was perfect as the grout lines on the floor were quite broad. I managed to get the grout covered and I've mopped several times and so far its stayed on so this is obviously great, but after a few tiles the tip of the pen started to wear down and got quite frayed which I then found difficult to cover the grout I got there in the end and was happy with the floor.

Really great way to update and refresh tiled areas!
Used the dark grey pen to update our utility room. Really easy to use, would recommend cleaning the grout as well as you can before using. Made the mistake of not doing this and then pen nib of my first pen got ruined. It’s worth to keep pumping the pen nib and shaking (with lid on) after each bit. This helps keep the paint flowing and gives better results and prevents drying out. You can go slightly onto the tile and then the pen wipes off really easily with a slightly damp piece of kitchen towel or cloth. This helps give a nice smooth finish. Really happy with results! Took about 3 pens to complete the room but if you’re careful with the nib when using I think you’d be fine.

Amazing product
Brilliant product, I used the dark grey on my white grout and the tiles look absolutely fantastic. I'm really pleased with the end result. The only thing I had a problem with was the nib of the pen. It was a little too wide but the pen easily wipes off the tiles once it's dried. I would highly recommend this product if your on a budget or not, youu won't be disappointed

Worked perfectly! Excess paint is easily removed from ceramic with a light scrub, leaving a nice sharp line. I had to blend in new subway tiles with an existing wall. I guessed on the grout color and sure enough, it was lighter than the original. Before scraping all the grout out and replacing everything, I figured I would give this a try. I was concerned that the excess paint would get on the tile and look bad, but it comes off with ease even after it’s dried. What a time and money saver!
