Using this specific product

PROSOCO Sure Klean Heavy Duty Concrete Cleaner is listed here as the Concentrated concrete cleaner version for concrete, driveway, and walkway. For cleaning or sealing masonry, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Concentrated concrete cleaner; related versions can use different timing.
  • For concrete, driveway, and walkway, pay particular attention to surface porosity, temperature, moisture in the substrate and rain forecast.
  • Do not let the cleaner dry onto the surface.

How to check readiness

Test a small area and watch for the stated rain-free and cure times. Use the stated range for this formula; rinse sooner if its directions tell you to stop for irritation.

Avoid this mistake

A dry-looking surface can still be taking up a sealer or repellent.
