Review: Great for a room refresh - Superb. Massively refreshed my hallway
Review: Very effective product, but nib doesn’t las - This is great stuff, I was amazed how good it was at making my ancient discoloured grout white again. It’s easier & cheaper than regrouting (especially if you have to hire a tradesman to do that) & you’d never know the difference. Unfortunately the nib collapsed so I had to order another one. The second pen seemed harder to get the white stuff to come out and it began to get too fiddly and time consuming, especially as I had a whole kitchen to do. As others have said, the nib is a design flaw. It’s hard to get the contents to come out without pressing the nib to activate it, but pressing the nib means it wears out pretty quickly. In the end I abandoned the pen & tried applying white paint with a small brush, wiping off any excess as I went. Looks just as good and much quicker. Also free as I already had the paint.
