Hi,
I had a leaky gutter which I fixed. Where the leak ran down the wall theres a decent growth of moss and I'm trying to remove it. Its a wet dashed finish so I cant scrape it off. I'm reluctant to use a wire brush as some guy I had in before did this and damaged the surface exposing bare stones.
Ive tried 2 moss killing products(cant remember names). I followed the instructions on them carefully and the moss looks dead, completely brown but its still stuck hard to the wall. I expected it to be easily washed off after it died? Do I need to just carefully wirebrush it or is there another way?
I also did the moss between my patio slabs at the same time and Ive had to wire brush that moss out because it didnt really loosen up, which I could have done without wasting money on a moss killer!
Can someone please enlighten me?

Thanks

Richard

Use a power hose.

Thanks guys. Ill try the vinegar trick! Powerhose wont move this stuff as it currently is. Ive just been cleaning my patio with the powerhose and I had to wire brush the moss from between the slabs first.

Thanks

Ahem!!!
Use a more powerful powerhose. It will work.

if your using a power hose hire a decent one with a motor never mind these fecky things that run off the mains and pump water through a narrow nozzle. A good power hose will knock the house down by removing cement between the mortar so be careful with it.

Thanks guys, I'm afraid of damaging the dashed surface if I use a 'proper' powerhose. I'll probably try vinegar and yard brush first

I use a Hand held Scraper on the Patio...this Tool is specially made to fit between the Slabs and "Hooks" the Weeds out very easily...the Moss can then be removed with a Wire Brush...

If you've still got the problem after all the above suggestions, a local farmer told us to use Sulphate of Iron to kill the moss in our lawn (applied September to March).

I'm pleased to say it worked so, if anyone can tell you whether there's a method of using it on a vertical surface without staining, it may be a cure?

Thanks Blowin/geranimo. I ended up using a wire brush on the patio and powerhose on the wall
