Frequently Asked Questions

Q. Can I use this product on Tarmac driveways?

A.NO-Resolva Moss killer is ideal for block paving and permeable driveways, but it should not be used on non-permeable driveways such as tarmac. This is to prevent run-off into watercourses.

Q. Following the label instructions, I noted that it is not recommended to use this product after 18th September. Why is this?

A. It is only registered for use between April and 18th September by the authorities, and in trials we noted that the product doesn’t work as well as in warmer weather.

Q. Does Resolva Moss killer kill weeds too?

A. Although it is only registered for moss kill, there may be incidental weed leaf burn, but the active product does not kill the weed down to the root.

Q. Can I kill moss on my lawn with this product?

A. No, this product will also damage lawns
