## Questions & Answers

**Q: If we use this adjacent to the grass will it kill the grass? TIA**
A: My patio is adjacent to a grassed area but I was careful not to let the solution run off onto the grass. I didn't want to take any chances and the grass is okay a week later.

**Q: Anyone tried this on black mould in a house**
A: No sorry worth a try though?

**Q: Will this damage artificial grass that is next to my patio?**
A: Hi, yes be careful to cover up plastic grass as I found it can turn the edges brown if the product gets orcruns on it. I used an old sheet to cover the grass area where the spay was going. Hope this helps!

**Q: Do you need to dilute this with water ?**
A: It’s ready to use.  I used it straight from the tub on the patio, but diluted it for use on the decking. Not sure if it’s suitable for decking but it came up great.
