Please do not drive on the concrete after 24 hrs unless you want to risk
damaging it!! It is scientific too. The mix , site preparation and

wetting it down in hot weather is a good idea as it prevents it curing too
quickly as the water content drops while the chemical reaction is strongest.
This helps prevent cracking and crazing. Concrete gets progressively stronger
with time , that can be years but is sufficiently strong enough for most
domestic usage after 7 days,with care. Once it is cracked,or marked it is
permanent. Patience required!
