filling the gaps in flagstone
(charleston, s.c. usa)
i'm starting my flagstone patio in 4 days. i have a 4 inch sand base. im looking for something to sweep in the gaps and just add water. what about sweeping in quickrete and misting water onto patio? will ths harded? i'm nervous to just use sand due to heavy rain in s.c. (on the coast)i dont want it to wash out. mortar seems to be very time consuming. any ideas?
