## Questions & Answers

**Q: If it leaches onto the nearby grass, will it kill the grass?**
A: I must admit I have just used it on my driveways and garage roof tiles which are well away from my lawns.  A general weed killer does leach into lawns and kill grass of course when mist spraying, but I'm unsure whether a moss killer does the same.  They are different chemicals for different applications, so hopefully it "may" not affect your grass too much.  But I am no expert in this subject.

**Q: What benefits does the Pro version provide  over  the basic  one.**
A: The Pro Version is a lot more concentrated. It should be used if heavy contamination or large areas are to be treated. Hope that helps, Josh@Smartseal

**Q: What is the difference  between this product and the pro version?**
A: The Pro Version is more concentrated.  Hope that helps, George@Smartseal

**Q: How many sq meters does 5ltr do?**
A: 5litres of moss clear, diluted 3-1 will cover approximately 60-80 m2 dependent on method of application and degree of infestation. Hope that helps
