Soooo got a bit giddy and started mixing my sand and cement ready to lay some pavers, filled the barrow with sand and cement powder, churned it all up, then noticed some ominous clouds. 10 minutes later it was hammering it down, stupid me. Now i moved the barrow into shelter before it rained, however it’s been sat there a day and obviously the sand wasn’t bone dry, do we think this is usable by adding the required water? Do i treat it like it’s just sand and add some fresh cement powder? Or do I just sack off the lot and go fresh?
