Green SLIME on pathways making things difficult.

sunny2004

I have green slime, it's not an obvious moss, just slimy when wet, covering all of my external paths.

Firstly what is the best method for removing it ?

Some facts,

I do have a drainage problem in the garden. But I have always had the problem.

It wasn't a problem for the last ten years, but got bad last year, so I power hosed it during the summer and it's worse now...

I have been told that power hosing it can cause small pits to allow it get a Better hold this year,..

HOW DO I DEAL WITH IT ? The slime..

And is there any product to seal the pavements ?

Thanks again.

Jeyes fluid or a spray with diluted bleach will work on most surfaces

While that sorts killing it it seems to only work short term.

I would love to have some way of sealing the pathway to prevent or slow its return.

Jeyes fluid at 150mls/5L water should kill it.

What type of paths are they? Concrete, gravel, slabs, paving?

Self-leveling concrete would work if they're concrete paths and the gaps are a few mm's. A scud-like mix would do for deeper concrete or slabs. Gravel needs to have the source killed and treated as soon as it returns, while paving needs more sand/grit maybe with a residual herbicide added.

Concrete paving it's perfect without cracks or holes. It's a little rough after power washing but not an issue under foot.

Could I use thompsons sealant on it ?
