Densi-Proof + Surface Repeller: 
Designed for brand new, clean concrete and the sooner you get it on, the better. The best time to apply it is right after the finishers come off, since it also provides a superior concrete cure. This is because Densi-Proof plus Surface Repeller holds the hydrates in, allowing more cement to ultimately be used. What this means is you don't have to wait 28 or even 45 days or more to protect your concrete. It can be protected immediately.
