I live in So Florida and its very humid here. I have an old chicago brick driveway that's sealed but keeps getting moss growth on it and when I pressure wash it I lose a lot of sand from the cracks. Any help on how to get the moss to stop or remove it easier?
The moss is growing because there is a source of moisture present (likely the ground beneath the pavers. The only way to reduce the moisture is to provide a better drainage layer under the pavers, but that means removing them and adding extra gravel and sand below, which turns into a big job (and likely not worth it). The pressure washing could be making things worse if you are removing even more sand from between the stones.
If permitted in your area, you could try spot spraying with a weed killer.Member
