I chose a still damp day in early November to apply the product as during these conditions the moss is more receptive to taking in the chemical than it would if the moss were frozen. With an eye on the weather forecast I managed to get a short break where no rain was going to fall as I did not want the spray diluted too much before it had chance to work.

For lightweight and maintenance use such as controlling algae, Patio Perfect can be used at a dilution rate of 1 part to 50 parts water which makes the product very cost effective. As I had got allot of heavy moss growth to control I chose the normal dilution rate of 1:20, and prepared for a full scale assault! Taking into account the product label I kitted myself up with required protective clothing and mixed up the Patio Perfect.

For best results, and like all other hard surface cleaners I have used the product should be applied to thoroughly soak heavy moss growth. Interestingly by the time I had finished spraying, the areas I had treated first had begun to darken. After three weeks the moss was totally dead apart from a few green patches that I had missed spraying! I shall mix up a further small quantity and treat these in the next few days.
