The editor that vector2 showed you earlier is not available in 2010. As
Jeff stated in his response it was changed in 2011. So unless you are going
to upgrade to the newer version you will not have access to that. Sorry.

I'm not that familiar with Revit 2010 but if this is a texture-mapped material, try increasing the Bump; this map is usually a black-white inverse of the original texture map, so increasing it may pop out the grout lines more.
