Rm43 is takes about a week to show visible results. But nothing will grow for year of treated ground. Moss will still probably grow. With that said, I would not use it on the stairs as run off could/ would leach into the surrounding plants. It says it on the directions. My walk way is in the same condition. I tape this to a paint pole extension and clean the cracks. https://a.co/d/0d4X6uCL I don’t have a pressure regulator on my washer so I’m limited to 2600 psi, it creates a fucking mess. So I use a hose and with jet, that washes out the sand also but not as heavily.
