### ⭐⭐⭐⭐⭐ Great Grout Pen
*by M***T on 26 January 2026*

For such a small product, it has done a wonderful job.

### ⭐⭐⭐⭐ Easy to use
*by A***E on 25 July 2025*

Works well. Easy to use

### ⭐⭐⭐⭐⭐ Brilliant stuff, why did I not find it earlier? 100% effective, makes tiled areas look fresh/ new.
*by E***N on 13 August 2021*

Loved this grout pen, left wondering why I didn’t know about it earlier. I am sure we all dread the day when the grout looks grubby and all you can think is re- grouting and the headache that will bring never mind the mess, costs etc. Well I can confidently say 100% this is all the stuff you will require. Some light preparation required ie cleaning the tiled area and let it dry. You pump/ depress the nib to get it flowing and then you find out how addictive this is, honestly I don’t think that I will ever re- grout again, all that is required is a steady hand and a damp cloth just in case you stray out of the grout line, easy. The end result is fantastic ( I was a wee bit disappointed that I had finished) and the area looks refreshed and actually New, no joking this stuff is so good I purchased another one for an elderly friend and although it hasn’t been applied as yet,I know she will not be disappointed. 100% one of my best DIY purchases, if you have the will to try you will not be let down ( No Expertise Required) and you will definitely be glad of the savings you make by not employing someone else to do it for you. Haven’t tried the floor one but I would 100% be looking to use it if I had floor tiles. This pen comes in different nib sizes so check your requirements before purchasing it. The colours are amazing and most people will find exactly what they need. The price for one pen enabled me to do the tiles behind the cooker with ease and no sign of it drying out whilst in use, pretty sure I could still get a touch up done if needs be. Take a look at the results off other work ( I don’t have a before& after but it truly is brilliant) and see for yourself. Long lasting result, waterproof ,has an anti - mould/ bacteria ingredient. You will love it .......
