Fantastic product
This product far exceeded my expectations. Incredibly easy to use - I drew down the grout line and immediately wiped along the line with a wad of kitchen towel. It removed all excess colour and left a pristine line as shown in the picture. The colour density is great, the colour is uniform throughout regardless of how โgrubbyโ the original grout was looking. It has transformed my tired looking kitchen floor back to new looking and it makes me very, very happy. I have steam cleaned the floor since applying and everything is still perfect. I would recommend this product.

Works well but beware the big nib!
This works brilliantly and has transformed my bathroom tiles. Easy to use but you have to judge when to wipe off the excess - too soon and you wipe from the grout, too late and it takes a fair bit of scrubbing to get it off the tiles. Also wasnโt expecting the nib to be so thick - I bought the large as had quite a lot to do but was just expecting a bigger volune not a bigger nib so be prepared for that. It doesnโt show it on the picture and this made the job slightly trickier.

Not as good as advertised
The colour and size are okay but the paint nib kept falling out during use even though I was not putting pressure on it, I kept having to put back in which made the whole application process messy and tedious.

So so
Brought 4 or 5 of these, the nips far too big, but u buy a small one and the nib just goes to bits, colour is ok but it gonna take at least 5 more to finish my bathroom touch up

Ich dachte es wรคre nicht so grau die Farbe aber habe diese trotzdem dann verwendet. 1 Stift hat fรผr das kleine Badezimmer ausgereicht, damit die schwarzen Fugen weg waren. Hoffe, dass das Ergebnis nun auch so bleibt. Vor 2 Stunde gemalert.

Super easy to use. Makes such a difference, brightens the room. So far I've bought 6 to do kitchen, dining, laundry, small hallway & a bathroom. Also bought the smaller pen head for another bathroom.

It covers well. Dries quickly. I am doing it in sections because the grout width is less than the extra wide (15mm) but more than the 7mm width. I have to clean the excess as I go. Because it dries quickly you need to clean the excess off the tiles right away. It is is slow going but the result is very nice. Seems to be durable so far.

This was just perfect. Big improvement. I used the light grey as I was told its better to use the light colour and they were right. People have commented how great my tiles look now.
