Flagstone mortar matching or polymeric sand to blend uniform color

David MickIrish

I have a very large flagstone patio. About 75% of it is very intact. The remaining mortar grout has been damaged. I took out all the loose grout. I went to a local supply house for mortar "that matched" and unfortunately it didn't match that well, even after it dried. Is there a way I can use some sort of polyermic sand that would coat the existing/stable joints as well as coat the new mortar so it blends together and doesn't look patchy?? Or any other suggestions?? Thanks in advance.
