More about Water-Based Dissipating Resin Concrete Curing Compound
The curing of concrete impacts its final strength and durability. In order to properly cure, concrete needs an adequate amount of water, both at the surface and within the material, for extended periods of time. Various methods can be used to reduce the loss of water from concrete during cure, including covering wet concrete with impervious paper or plastic sheets, or applying membrane-forming curing compounds. Concrete curing compounds are liquid-applied and conform with ASTM C309. They come in a range of types, with base material options including acrylic or styrene copolymers, chlorinated rubber, waxes, and hydrocarbon resins. Some curing compounds are temporary or "dissipating" and break down in about 4-6 weeks from exposure to normal construction traffic and UV light. Other curing compounds are more permanent and will remain until removed; within the more permanent types, some are considered sealers as well and curing compounds. Both water-based and solvent-based formulations are available, though water-based are more common. In addition, curing compounds can either be clear or white when they dry, where white-pigmented products can be used in hot, sunny weather to reflect solar radiation and keep the surface cooler.
This CP focuses on water-based curing compounds that are unpigmented and dissipating. They fall under ASTM C309 Type I, Class B. These products may be used on interior or exterior, vertical or horizontal concrete surfaces. Once the product has dissipated and/or has been removed, paint, adhesives, sealers, densifiers etc. may be applied to the concrete.
