## Questions & Answers

**Q: Can it be effective for red & black algae on cream-rendered exterior walls, without damaging the render finish?**
A: Green Clear PRO can be used to kill and remove red and black algae on cream coloured render. A soft brush can be used to remove organic growth on badly contaminated areas.

**Q: How would your product be applied to a house roof?**
A: Green Clear PRO is usually applied by a sprayer. In the case of house roofs, depending on access, it can be sprayed from a ladder or scaffolding. If the roof is not that high, then it can be applied using a sprayer and an extendable lance.

**Q: Does it also clear weeds, please?**
A: Green Clear may kill some types of weeds, but is not regarded as a weed killer. It would be best to purchase a specific weed killer for that purpose.

**Q: Is this product animal/bird friendly?**
A: We would not classify the Green Clear Pro as animal or bird-friendly immediately after application. Once dry, it is totally safe for birds and other animals to walk on.

**Q: Is the product acidic?**
A: No, Green Clear is not acidic.
