Finally a product that works and actually does what it states. I needed to paint a customers fence that was full of green growth, pump sprayed this on 1 week before scheduled to paint, went back 1 week later and was amazed, much better than I had hoped for. Even the neighbours were asking what I had used, so passed on my new findings.
Great product, great price!
Thank you.

Used this product before and it is brilliant, sprayed on patio and by the next day most of the algee had lifted, no washing down needed, if there is a stubborn patch just reapply and lightly brush if needed.
