My front porch and steps are made of concrete. Water from the lawn sprinklers pools on one of the steps because the step apparently wasn't finished quite level. The water pools, then evaporates, then pools again on the next cycle, etc., etc. It's not deep -- it evaporates within an hour or so on a warm day. But when it's more or less dry, it's greener and greener, apparently from algae forming.
Is it possible to "refinish" the top of a concrete step in a manner both practical and aesthetically pleasing? If it's hundreds of dollars, I'll live with the "moss." But if there's a cheap and effective remedy, I'd love to know about it.
