Stone Mason Concrete Accelerator is a non-corrosive liquid for portland based cement mixes. It accelerates cement hydration resulting in shortened setting times and increased early compressive strengths, ideal for very cold conditions reducing the time that concrete must be protected against freezing. It speeds finishing operations and form removal in any weather condition. It provides early strength development similar to that provided by calcium chloride but without the corrosive effects.

Use with Stone Mason Vinyl Cement, Surface Bond Fiber Cement, Patching Cements, Foundation Insulation Cement, Glass Block Mortars as well as Concrete and Mortar Mixes.
