Green Flags

[con1_uk]

I only had my new Indian stone flags laid in the summer and the are already green. Do I need to keep powerwashing then or is there something better to prevent the green?

Thanks.

Try Jeyes fluid diluted to the correct strength. If the slabs are north facing then unfortunately they will always be susecptible to going green.

Thanks for your reply.

Is that to clean the stone or to prevent them going green once cleaned?


Thanks.

Both.

try to avoid power washing them, they will wear down very quickly if you do it too often
