CURING MACHINE

A curing machine for curing freshly-laid concrete slabs has a sprayer for spraying a curing agent-in particular, a dispersion-onto the fresh concrete slab in order to prevent premature drying out of the concrete. The curing machine includes a controller which works together with an operating unit for the automatic actuation of a pump and of shut-off elements of the liquid system of the sprayer. The controller is configured such that, by manual actuation of the operating unit, at least two operating modes from the group comprising filling mode A, spraying mode B, mixing mode C, and cleaning mode D can be selected, wherein, after selection of an operating mode, the at least one pump and the shut-off elements assigned to the selected operating mode are actuated in such a way that the selected operating mode is executed.
