Rated 5 out of 5 by from Great product This was my first time grouting and this product was great and made the job easy. Mixing instructions and consistency was great and the product spread well. Wear thin gloves to avoid the colour getting in and around nails

Rated 5 out of 5 by from Good stuff Got this to grout a 2mm gap between large tiles in the bathroom and around shower. Very easy to mix up and use. Very messy though so make sure you put something down beforehand

Rated 5 out of 5 by from Only choice for me I would only consider this grout. Follow the instructions and you can't go wrong. My advice would be to always wear a mask while mixing. The dust is extremely fine and will always get in your lungs.

Rated 5 out of 5 by from Great colour & product I used this with black tiles. I was going to use black grout but had run out. This looked like a great alternative,as it gives a contrast to the black tiles rather than black on black. Mixes well smooth consistency and goes on well. just remember to get plenty of wipes and a spreader / cleaner just for this colour as you will not be able to use it for any other colour after as it stains everything. I have a bucket of them for different colour grouts... Performs very well in wet areas too, kitchen splashback shower areas etc
