What happens here

After control joints are cut, apply a surface retarder (like Day One) using a sprayer. This product slows down the curing of the top layer of concrete, allowing for a longer workability window to achieve a smoother finish. This is not water, but a specialized chemical mix designed for concrete finishing.

Goal: Extend concrete workability for a smoother finish

Tools and materials

Sprayer — Applying surface retarder evenly
