'GREEN CLEAR' PRO Kills & Inhibits All Green Growth- Safe, Quick & Easy
Product Reviews
By Ian Cunningham

This stuff is brilliant. I have a brick patio which for most of the year is in the shade. It was regularly green with moss but not now. One treatment with this product keeps it moss free for at least a year. No more pressure washing!

By Chris Shorter

We have used this product on our club tennis courts and it seems very effective in killing the moss after about a week- though one needs to be careful not to use it when rain is expected in the next few hours as that reduces its effectiveness. I would certainly recommend the product.

By M Heffron

I purchased this back in April of this year but haven't got around to using this until now. I have more block paving than you can shake a stick at and I must confess I was a little sceptical as to whether this would work and how easy it would be to use. I applied using a 15 ltr Solo backpack. I was conscious having watched the videos that I needed to ensure a good covering. I have to say 24 hours later, some areas of moss have shrivelled to black others are now brown. The very heavy areas are still green but are not looking as healthy as they were 24 hours ago. So far, so very good.

Product FAQs

Q: How long after applying green clear pro can you put climashield roof coating on Thanks

Chris Clarke

A: You would want the roof to be dry for around 2 days prior to applying the roof coating. Moisture can act as a barrier for the coating to adhere to the surface.
