Review: Easy to use. True to colour. The grout in our bathroom was very dirty and discoloured. Needed a good deep clean, after a scrub and using this pen our bathroom looks brand new and sparkling! We have floor to wall tiles and I managed to do about 90% of the room before the pen ran out. Have purchased another! Very impressed :)
Review: Ha sido muy fácil usarlo y el resultado es muy bueno. Pedí el gris claro y quedó perfecto. Es lo estaba buscando.

- For use on unsealed grout only: Grout pens may not stick to sealed grout. Test grout with a few drops of water. If the grout does not absorb water within a minute, it means that the grout is likely sealed

Great product, so easy to use, literally just need to draw lines through the grout, that’s it and it’s done. No harsh chemical smell either. Regarding the colour, the chart shown is what the colour looks like on the paper but since grout is a different texture, therefore the actual colour would be lighter.
