(Don’t mind the message😁 )Been thinking of options so it doesn’t need power washed every month
algae -- have to keep it dry! is it at ground level where water accumulates after a rain ?? Clean it ( pressure wash! again!), get it BONE BONE dry ( if you can ) then use an outdoor concrete sealer ... Seal-Krete makes a good product .. but prep is everything!
You'll probably need some form of fungicide to keep the mold from coming back. You also should reroute any water that is getting to the area from down spouts or A/C condensation. If you can keep the area dry you are halfway home.
Try Never Wet. It makes water roll of of things. Use several coats after you have thoroughly cleaned and let dry.
Use bleach water. Will kill mold
Use Spray & Leave on it and it will be taken care f!
If you don't mind it power wash it twice a year. That is what we do with our sidewalks.
Vinegar will kill what you've got growing there. It may need to be done several times a months but it works with a quick rinse.
