Poly carb roof

[Andy]

@daveyboy you did tell me once before but I can't find it. Hypo 14/15 % how much for a 2%. Mix in a 5lt sprayer. And will 2% be ok on a poly roof.

If it is 14% and you want 2% then that is 714ml hypo and then top up with water to 5l

If you assume it is 15% to be safe then 666ml hypo

I sometimes use it on roofs but usually i mix it a bit weaker and spray it twice but 2% will be ok
