I set 6 4x4 fence posts yesterday using that quickrete for setting posts. You just pour it into the hole then pour water in and it sets. 4 of them hardened up well but 2 just didnt. I can wiggle the post like the concrete didnt get hard enough or something. i removed one and it just wasnt dry, so i re dug out the hole and re-did it. Better this time but still not solid like the others were. Wonder if the sackrete brand would have done better..anyone had this problem with this?
Thanks
