I'm just wondering if anyone has done this and if it worked well.
We have a concrete basement staircase that is a bit so-so and would need a renovation.
Right now, there is some sort of tile history that is starting to come loose in some places.
Since it's shaded all day and when it rains, it stays constantly damp and has a lot of algae, making it very slippery.
Is pressure washing a good idea or has anyone done something else that's effective?
