Me and a mate layed a concrete slab base and it has turned out pretty well on saturday 28th June yesterday.

This morning I removed the covers and the slab is looking good and is hard. Tonight and tomorrow they are predicting showers and what I want to know is should I cover the concrete again or is it now ok for the rain?
