Treat fence before re-painting?

[Ljc1980]

It's been several years since I last painted our fences. I think I used ducksback red/cedar paint/stain.

Id like to crack on and repaint it all but it's now got green algae on a quite a bit of it.

Should I be treating this or trying to remove prior to reprinting?

Any recommendations on products to use would be great!

Thanks

you can jetwash it off, that will take you back to bare wood. If the day is sunny it wll probably be dry enough to repaint the next day (fences are thin, exposed to the air on both sides, and dry out quickly.

Warn your neighbour, because the flying water is dirty, with bits of stain and wood in it, and will ruin washing or mark cars and other clean surfaces.

There is a treatment/product to remove this, but JohnD’s suggestion is cheaper and better

I used a stiff brush to clean down out pannels then Ronseal Fence Life Plus hand painted over top.

Probably 160ft + back featheredge fence to paint both sides..
