Hey everyone. I'm getting ready to tile my pool, I have these really cool grey tiles but I can't find a matching grey grout/ mastic / adhesive to go with them. Have you guys ever heard of using concrete colorant to tint the grout? I'm thinking of getting white grout and adding some black concrete colorant to make grey. I did some samples and it looks really nice but I'm worried about it changing the properties of the grout. I only need about 1% by weight to get the color I need. Any experience with this kind of thing out there?
Thanks in advance for the help and advice.
