What type of damproofing can we put over new concrete floor in garden outhouse ?

Wooden garden outhouse 15x10 had leaking roof which damaged the wooden flooring, roof newly repaired, all wooden floor taken out to base concrete and had new concrete put down 3 weeks ago, only to realise we should have done some reseach first as we should have been advised to have damp proof membrane put down under the concrete. We were then advised to have 2 coates of Epoxy Liquid membrane painted over the concrete, however we have been quoted £800 to have this done, could we buy the Epoxy liquid and do the job ourselves ? If not can you advise if there a cheaper solution ? Many Thanks
