Winter grey good with white tiles
Lots of reviews here saying 'Winter Grey' is useless as it's white. It's not, it's got a very slight grey tint to it which is exactly what I wanted to define my white kitchen tiles (grout was white before). Hopefully the photos show this well. I think with darker tiles, yes, it would probably look stark and almost white because of the contrast. I bought this and 'Light grey' to compare light grey on white grout next to white tiles comes up very dark grey. So, in summary, 'winter grey' is good for white or very pale tiles and 'light grey' probably better for dark tiles. Hope this helps .

Easy to use, look good but do come off quite easily
I love these pens, they are super-easy to use, non-toxic, good colours - the only thing is they do come off quite easily as they are water soluable, but if you don't mop too often, it lasts a while, and re-applying is quick and the pens are cheap so it is fine with me.

Easy to use and do the trick
Love these grout pens for touching up grout. I used on my kitchen and bathroom floor tiles and they have lasted 3 months and counting with no fading or cracks. They have an antibacterial coating it says on the packaging, so was easier to use these pens to cover the grout rather than scrubbing with rubbish grout cleaners. Also very easy to wipe excess off, so can be done in a rush. I also use a steam mop with blasts of steam directly on them and they have lasted well

Good product but not quite the colour I was expecting
Product is easy to apply and works well to refresh the old grout. Although described as winter grey I would say it is more like a winter white. It's a shame that it is not quite the colour shown on the chart. I'll live with it as it is as I think the light grey will be too dark.

Over the moon with the results!
This is the best thing I’ve ever purchased! I have Matt grout on my floor which is now two years old and because it’s porous, It has stained easily with footfall. I have used every grout cleaner I think on the market, every magic sponge, every bleacher but nothing shifts the stains. This was my very last attempt before paying a fortune to have the grout chipped out and relaid with silicone. I am over the moon. The pictures don’t do it justice. It looks just as nice if not better than when my floor was first laid. I can’t thank unibond enough for this product!

Colour chart incorrect
Don't waste your time or money relying on the colour chart, unless you want black or white. Ordered Winter Grey, the colour of the pen received looks nothing like it, it's more like Light Grey. Yet a reply from the company says "The Winter grey is very similar to the light grey which can be confusing." If they think these colours are similar, are they colour blind!

Quick fix but not waterproof
Really good for the price as opposed to getting tiles redone, took about 20 minutes. it’s definitely my mistake as it does say water based however it is definitely not waterproof or even water resistant, don’t make the same mistake as me and use it for bathroom floor tiles 🤦🏻♀️, I’m not mad as I’m going to use this for my kitchen tiles also, and get a waterproof one for the bathroom floor.

Fabulous results! Highly recommend!
Really impressed, had my doubts when ordering, as if heard good and bad comments! But, i can honestly say this pen has transformed my kitchen wall tiles!! They were looking tired and quite dirty looking, as i have white tiles with with grout... so i bought the winter grey grout pen , and they now look like new!! I bought 2, but only needed the ine, and still have some left!!! Would def recommend... for a marker size pen, it goes a long way!!!

Für durch Malerrenovierung farbverschmutzte Fliesenfugen prima geeignet. Der recht hohe Preis ist wohl der Farbenvielfalt und der geringeren Nutzung gegenüber normalen Permanentmarkern geschuldet.

If you don't have a large area this is the perfect "Tile Paint Marker" to touch up your grout. After using it, to cover my bathroom grout that had turned an unpleasant color over the years, my tiled bathroom looked like new. The only drawback using this pen is that grout can be abrasive and it will gradually wear the tip down. It did maintain it's shape enough to finish my small bathroom though. All in all a perfect way to refresh that aging discolored grout.

I used this product to do my shower grout and it looks great. That was 3 months ago. So when I needed it for chips in my kitchen tiles tried it and it covered it beautifully, Beats replacing all the tiles
