Our brick steps have had to have some work in the past. Re-pointed and patched last year... we already had moss and weeds growing on steps. We pressure washed and waited a week until really dry. Sprayed product on and really pleased so far. water beads up and steps are dry much faster than before
This was early November 2020
application went really well and were super pleased with the look and the water beading on the bricks
wife believes the bricks look newer and leaves clear with the wind and don't stick
happy wife = happy life!

I recommend this product for use on red clay brick and mortar surfaces
