not having used this material, the method's still the same,,, crack repair's not like repointing,,, when you repoint, the reservoir's there & & just needs cleaning & filling,,, for proper crack repair, you need to CREATE the proper sized reservoir ( usually by chasing the crk w/diamond blade & 4" grinder ),,, google/ging that material & see what the product sheet says it needs for the repair to be acceptable,,, otherwise, if you don't feel comfortable doing that, pick the masonb w/whom yhou are most comfortable,,, saving a couple $$$ will haunt you IF the repair's ineffective as you'll just call in another guy & pay more $$$ not to mention listening to your bride, nagzilla, remind you she liked the 1st 1 better :furious: brides always 2nd guess !
the above poster, pwgsx, likes caulk in moving joints,,, i'm hesitant joining that opinion :whistling2:
