Great Consistent Product

Purchased this after having it recommended as a "true black" grout, that is, it is black and stable with little or no fading to dark grey/black. I'm glad I followed the advise, consistent color over the 2.5 bags I used. It's important to try and keep the water/powder ratio as close through each mix but it works very well.

Great colour, quality and price!

As a first time tiler and grouter I found this stuff really easy to use and the ivory colour was a lovely contrast against the cream tiles. Would defo recommend easy to mix and spread! Easy to wipe off afterwards too!

Easy to use and very effective

I needed to carry out some maintenance in our bathroom which included some repair work to both the wall and floor tiling. I only needed a relatively small amount of black grout but this was the smallest pack I could find. It mixed really well and was so easy to apply. During the application process any surplus was easily removed and the areas cleaned up really well. I left the grout to dry thoroughly over several days and the finished result looks brilliant. Thank you.

Just the job it was easy to mix and apply for a small repair.

Difficult to work with

I'm a DIY enthusiast not a tiler. But jeez I found this grout difficult to work with. Sets too quickly, and very hard to clean. Because it dried too fast, I had to grind it out of the first wall I did and regrout. It cracked and didn't fill the gaps properly, ended up leaking around the shower. I'd avoid unless you are well experienced with it.
