PART 3 - EXECUTION
3.1 CONCRETE PROTECTING AND CURING
A. Refer to Specification Section 03 30 00, "Cast-In-Place Concrete" for information and
requirements for concrete curing procedures.
B. General: Protect freshly placed concrete from premature drying and excessive cold or hot
temperatures. Comply with ACI 306.1 for cold-weather protection and ACI 301 for hot-
weather protection during curing.
C. Evaporation Retarder: Apply evaporation retarder to unformed concrete surfaces if hot, dry,
or windy conditions cause moisture loss approaching 0.2 lb/sq. ft. x h before and during
finishing operations. Apply according to manufacturer's written instructions after placing,
screeding, and bull floating or darbying concrete, but before float finishing.
D. Formed Surfaces: Cure formed concrete surfaces, including underside of beams,
elevated or supported slabs, and other similar surfaces. If forms remain during curing
period, moist cure after loosening forms. If removing forms before end of curing period,
continue curing for the remainder of the curing period.
E. Unformed Surfaces: Begin curing immediately after finishing concrete. Cure unformed
surfaces, including floors and slabs, concrete floor toppings, and other surfaces.
F. Cure concrete according to ACI 308.1, and the following methods:
1. Curing and Sealing Compound: Apply uniformly to surface areas designated to
receive curing and sealing compound, in a continuous operation by power spray or
roller according to manufacturer's written instructions. Recoat areas subjected to

heavy rainfall within three hours after initial application. Repeat process 24 hours later
and apply a second coat. Maintain continuity of coating and repair damage during
curing period.
3.2 LIQUID FLOOR TREATMENTS
A. Hardener-Sealer Treatment: Prepare, apply, and finish specified concrete floor areas
according to manufacturer's written instructions.
1. Remove any overspray of curing compounds, or sealers, and any additional oil, dirt,
laitance, and other contaminants and complete surface repairs.
2. Apply to concrete after time-period recommended by floor treatment manufacturer.
