I live in an area with bad freeze/thaw cycles (Northern Michigan). A customer wants a flagstone patio set in mortar. I’m afraid the mortar will crumble and look bad in a few years. I was thinking setting the stone in sand and ‘grouting’ with polymeric sand.
Has anyone tried this? How does it work?
If so, how deeply should the cracks be filled with polymeric?
How much polymeric is used assuming joints of 1″ or less on the stones?
I’m doing about 1150 s/f of patio.
Thanks
John
