I hope you can all help me as you did with the advice i got in laying the patio
i have an East facing garden that has a 36sqm patio laid in Indian sandstone on a full bed of motar with cement pointing.
Some of the lighter/whiter flags have now got a green algea forming on them
Is there a product to either get ride of this or stop it all together
Cheers
Craig

In short: Annual jetwash (that's what I do with my own, anyway).
