Jgbigard,
You said " Then I also take sodium silicate and mix with 1 part water, put
into sprayer and spray the completed concrete pour or ferro-cement to seal the
surface to lock in moisture so will cure and not dry."
Can you give us an example of when you would want something to cure and not dry? And what Kind of sprayer are you talking about? A paint turbine? High pressure?
Thanks
Ron, a pumpup garden sprayer works best for this process, aslo I did a search for "concrete curing" and found this information on the internet.
"For centuries curing concrete has been accomplished by bathing green concrete with water, moist straw or burlap blankets. Actually, Water Curing concrete consistently for 14-28 days remains a sound method of curing concrete, but labor conditions have rendered this method impractical except for extremely unique projects.
During the chemical age of the 1950's, in an attempt to reduce labor costs and increase consistency, curing concrete with Thin Film Curing Agents came into practice. This time also marked advent of retarders and accelerators – some of which may not have a positive affect on concrete quality. Thin film curing agents, typically acrylic resins or wax, are designed to remain on top of the concrete during the 28 day curing process. Even distribution and thickness of the film layer is critical to obtain the desired mvtr - as such proper application is critical. When functioning properly these films dissipate by the conclusion of the curing process. However, variance in temperature, weather conditions and exposure to UV light make the timing of this process unpredictable. If dissipation is incomplete uneven blotchy appearance may occur. In almost all cases grinding, stripping or shot blasting is required to commence with permanent sealing or coating, which adds additional labor cost and time cost."
