Rainbow chalk markers grout pens
Great stuff! I was a bit dubious about grout pens, having read varying reports, but these pens more than delivered. I used the light grey, and was very impressed with how well they covered my old grout. So good, I'm gutted I haven't got any more tiling to use them on lol.

Easy to use although be aware it is a blue-grey colour
I like these grout pens. They do a great job of refreshing grout. Used lightly, one just draws lines along the grout. Any overspill on a tile can be wiped off. Some people think the nib is too soft, falls out etc. I found using in lightly and slowy means I have no issue with the nib. I found this grey pen to leave a blue-grey colour, not light grey. This was fine for me, but may not suit everyone.

Amazing Transformation
Product arrived quickly. Instructions were easy to follow. Colour was perfect if a little darker than my previous original grout. I had previously tried use cheaper alternatives with little success. The product was perfect. The paint/ application was smooth and steady. 1 pen did my entire bathroom. (9 ish 600x600mm tiles) with plenty of paint left over for areas I had missed.

The light grey colour has a very blue undertone
Product works well and is easy to apply on smooth clean grout. (The nib will wear quicker if you have old/ uneven grout and use too much pressure). Purchased to cover white grout lines on my grey bathroom wall tiles. My tiler put light grey grout on the floor and white grout on the walls so I was hoping to match the existing floor grout colour. I like that product has anti-mould properties. The grey was a light-medium depth in colour, leaning more towards medium when applied- it was quite a bit darker than my existing floor grout. I only needed one coat, but it showed up very blue against my tiles which ultimately clashed and would have made my bathroom look too cold/ sterile. (My tiles are more like a natural stone grey effect so they have some warmth to them). Luckily I just used it on a test patch out of sight in the corner of the room. I'm going to look for another product with a better colour match. Unfortunately I cannot comment on the longevity of the product or the anti-mould functionality. I think this is a great inexpensive option and product if the colour matches for you.

These are amazing. l have tried many ways to clean my home grouts before. But nothing other that regrouting ( which is a time consuming, labour intensive, expensive process) worked before this. But this product is so so amazing. Its as easy as using a marker and all you have to do is draw lines with it on your grout to hide the dirt and provide a very clean and fresh look to your grouts. How many pens you need depend on how much dirty your grout is. In my case, one pen pretty much covered about 150 feet of grout surface. Very happy to have discovered this product. Grout cleaning is not such a big headache anymore!

Sehr gute Preis Leistung, hebt bei mir in der Küche schon seit über 2 Jahren. trocknen bei richtigem Lagern mit Deckel auch nicht schnell aus. Und mit zwei Stiften können auch 2 Leute gleichzeitig Fugen nachziehen.

Marre de récurer à la brosse à dents pour un résultat qui ne reste que 2 semaines. J'ai investi dans ces crayons, très simples d'utilisation. En un seul passage, mon carrelage a un bon coup de jeune. A voir dans le temps, je reviendrai sur mon commentaire pour l'évolution

Wie auch die anderen Farben, gute Deckkraft und gutes Volumen.
