Curing helps produce high-quality concrete floors. If a floor is to receive a coating before it is put into service, however, the choice of curing method affects preparation costs. Choosing the right curing method will keep the preparation costs as low as possible. Five frequently used methods for keeping concrete moist and the floor preparation methods to be used with them are as follows:
Method 1: Adding water externally. This retains mixing water in the concrete by keeping the concrete wet during the early hardening period. Preparation for coating requires only scrubbing the floor with an organic acid to etch it slightly
Method 2: This process involves covering the concrete surface with reinforced waterproof paper or plastic sheeting to prevent moisture loss. Again, prepare by etching with organic acid.
Method 3: This technique involves applying membrane or film-forming curing compounds in order to prevent evaporation. Preparation for coating after this curing method requires a costly solvent mixture.
Method 4: Applying dissipating membranes leaves an easily removed residue. Scrubbing with an organic acid will suffice as preparation for coating.
Method 5: This method uses hardeners such as sodium silicates to slow the evaporation of water. A solvent is not needed for floor preparation, but a stronger organic acid treatment is necessary.
