## Questions & Answers

**Q: I have a lot of moss and algae growing on a painted rendered cottage, is this a good product for use before repainting?**
A: I only used it on patio and it was not very effective so gave up using it.  I have painted rendered walls on house and my decorator applies a decorating exterior algae remover and leaves for 24 hours before hosing down, using stiff brush on stubborn stains.  He then applies algae inhibitor before painting walls with exterior wall coating.  I believe both these products are available from Amazon.

**Q: Does the product remove black mould from natural stone?**
A: Did not work for me. I now use a pressure washer with a patio cleaning head and get perfect results which last for several years.

**Q: Is this definitely good on roofs and gutters?**
A: I don’t see why not but I use it for the algae on my terrace and have not used it on roofs and gutters. It works very well for me.

**Q: can it be used on a balcony covered with a rubber membrane**
A: Don't know Joyce.  It's really good stuff, doesn't smell chemical but reckon it must have something potent I it that might damage rubber.  Think I'd get on to the company if it were me best regs cathy
