Pour, Finish, and Cure Concrete Deck 21
3. The first module can be bull floated to final level while the second module is being poured (see
Figure 6-5). Edge all concrete/metal frame joints.

4. Pour, screed, float, and edge any remaining modules. After the concrete deck surface has hardened, brush
with a broom to provide safe traction.
5. Clean concrete splatters from the painted frame members with a wet sponge before they dry, and before
applying a liquid curing agent.
6. Apply liquid curing agent to complete concrete pour and finish (see Section 6.3).
6.3 Moist-Cure Concrete Deck
For proper curing, the surface must be kept moist for seven days. If the top surface is allowed to dry out during this
time, the finished surface is prone to unsightly spalling and surface cracking. Hot weather, full sun, and windy
conditions all accelerate surface drying.
The easiest way to keep the surface moist for seven days is to roll or spray on an epoxy-based concrete curing
solution immediately after final finishing. These epoxy-based curing products are available at contractor-supply
companies. They both seal in moisture for slow curing and protect the surface from salt and corrosion.
Some curing agents can have adverse effects on steel surfaces. Please refer to assembly prints for proper
curing agents.
Alternately, the surface can be covered with continuous plastic and kept moist by frequent flooding beneath the
plastic for the seven-day cure period.
