Hi everyone,
just wondering if anyone knows if we HAVE to cover the slab in our alfresco area or if it is only to make it look nicer. We were told that we need to cover it with another layer of concrete/exposed aggregate or something like that but not sure if that is just to make it look nicer or if it is must for another reason cracking or something??

Eventually down the track we might like to cover it with something but atm just trying to prioritise what is a must and what isn't as we are really tight on money and moving in to our new house in about a month.
Thanks for your help
