Default Resurfacing drive - best moss/lichen/algae killer

The drive is to be resurfaced but before I have it done I want to get rid
of Moss etc.

Thoughts are to give a double treatment a couple of weeks apart before
machine brushing (Bobcat mounted brush) to remove the dead moss and loose
surface dressing.

Glyphosate will be used also as a systemic weedkiller.


Glyphosate will kill growing plants, but it won't touch moss.

Any recommendations on the best *moss etc* killer applicable during Feb/
March months - staining will not be a problem due to the resurfacing.


Ferrous sulphate (iron II sulphate). Light green powder. You can get
it pretty cheaply if you buy it from ebay or amazon.

It will oxidise to some extent when you mix it with water, and then a
bit more when it's exposed to the air. It can stain concrete orange.
