Here is an odd one. The owner wanted black grout between the limestone. But instead of a regular cementious grout they used black sand mixed with other things he refers to as sweepings. They mixed with some sort of acrylic binder. Now when the rains come the grout is partially washing out. They want me to fill in what is missing (It's not dramatic) with more sweepings and then possibly mix with something a little more binding than the acrylic to help it all stay in place. A little like doing Little Richard's hair. Any ideas?
Thanks
Baird
