Slow Willie Concrete Retardant is an easy to use powder that will give you more time before the mixture sets. Easily mixing into the concrete, the concrete retarder gives you up to 3 hours of setting time for one yard of concrete, without affecting the structural strength of the mixture. Operators will have an easier time getting their pump to the proper clean out location before the mixture sets, making the clean out much easier.
Slow Willie Concrete Retardant contains 20 16oz. bags per box.
