Review: These pens are grout! - Never thought I'd find myself impressed with a grout pen, but here we are. previously tried the cheap ones you'd find in pound shops or your usual budget diy shops and have been left less than impressed, but these pens work perfectly. They're nice and... runny? good flow and coverage, the colour matches my dark gray slate tiles perfectly and they're super easy to use and clean up should you make a mistake. To get them flowing and working well, you just give them a good old shake, press the tip down on a hard surface such as the back of the packaging and repeat until the tip is covered.
Review: Easy, but colour is Grey. - Really easy to apply, but I’d say colour is grey, not Dark Grey as stated.
