Slippy Steps And Flag Stones In Wet Weather.

After a time natural stone steps and paving such as flag stones tend to build up a layer of algae and lichens which become slippy in wet conditions.These are in effect small micro plants feeding on the build up of humids and nutrients on the natural stone over a period of time. The best course of action is to apply jeyes fluid to the area with a watering can then leave for 3 weeks then pressure wash the area or apply a patio cleaner.The jeyes fluid will kill the moss and lichens making them easier to remove.
