Hi there,
I'm starting a new project to improve the shady area along the side of our house. I'm particularly keen to improve the view from the laundry (picture below) and would like to go all out on this small section of the fence by installing a lovely vertical garden....

My first step is going to be to paint the whole fence along the side border of our property (around 30 metres) a charcoal colour.
This product looks to be what I might need...

However, the fence is looking a bit green in places (see the next two pictures), so I'm not sure if I can paint directly onto the fence, or if I should give it some kind of treatment first... I'd be really grateful for any advice...


With thanks,
Anna
