Morning all

I'm laying slate down on our limecrete floor, but want to darken the mortar used for the grout. Has anyone done this? I know a pigment can be used for plaster, but can't think of any good reason why it can't be done for a grout mortar as well. Or is there some other way this should be done?

Thanks

Thanks Tony

I've got about 50sqm to grout when all done, but will be doing adjoining rooms at different times. Therefore I was thinking of making a mix with lime putty. That way I can do a large batch and store it until required for each stage - easier than trying to ensure the colour matches.

Will putty be strong enough for a floor grout though? I will be leaving 10mm spacing between tiles

That's great, thanks for your help tony
