What is the best or most popular grout colour for riven black slate floor tiles?

Hello Ron

The most popular choice of colour for grouting black slate floor tiles is our Anthracite Ultracolor Plus grout from Mapei.

This is dark enough to hide a multitude of sins over time but is light enough to see a little definition between the grout lines and the tiles.

For further advice on grouts and grouting, please feel free to call our sales team on 01283 730388 who will be happy to advise you.
