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.

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

Cheapest would probably be salt grit, or normal salt.
I did my path a few winters back and when the rain washed it away, it was
immaculate. The remainder of the paving was still green where no salt had
been applied
