Man did I do it now. We put in a flag patio last summer. I had to have surgery and as a result the emps I had work for me did a shoddy job. As I want to make good on this mess even at the great expense it will cost. I need some advice. When stones were set, many were not cleaned or grout smoothed. Grey matter everywhere now. There are areas of pretty thick stuff to clean. I heard today that sandblasting will clean up things pretty well. Any thoughts? Secondly, is there any resource to learn an economical way to cut flagstone to fit tightly w smaller joints? Are there templates? What do you guys do to get stone to cut and fit nice and tight? Just need to get some tips to be a better installer. Really need help here thanks!!!
