    I was planning on making a concrete slab tomorrow to form the base of a new shed.

    Temperatures overnight are forecast to drop to -2° C. Am I likely to cause a curing/freezing problem as the concrete sets or will it be fine if I cover it with a couple of sheets and some polythene over the top?

    I would wait, It's not worth the risk

    If it was forecast to be 1 or 2 maybe but -2 is quite a hard frost and its going to go off so slow this time of year you'll struggle to get bleed water off it before having to slap covers on and it'll leave an awful finish on it.

    If you do go ahead use more than polythene, use something insulating like cardboard/ old carpet/ hessian etc.

    I went ahead and protected the new stuff with some old carpet.

    For what it is worth I am an idiot who bought a 6x8 shed to go on a 5x7 base so I only had a to build up a 12 inch wide L shaped to extend the base. The finish doesn't matter that much as it will be hidden.

    Fingers crossed.
