Concrete develops its strength by the reaction of water
with cement, so it should be prevented from drying out
too quickly, otherwise a weak, poor quality surface
may result.
As soon as the surface is hard enough to resist marking,
cover the concrete with plastic sheeting or waterproof
building paper and secure well, especially on the edges.
This will keep the moisture in.
Another method is to spread a layer of hessian or sand
over the surface and keep moistening it continuously.
This process of keeping your concrete damp is known
as “curing”. Your concrete will continue to gain strength
for at least one month provided curing is continued for
that time. |
