5 Litre Concentrate Spray & Leave Cleaner - Patio Fencing Decking - Green Mould & Algae Killer

Q: How good is this for thick moss and do you need to dampen or crush the moss to let the product in?

I would suggest the best results are obtained by: 1. removing most of the moss manually first i.e. scraping the moss of the driveway 2. spraying thoroughly with moss remover - avoid run-off. Preferably ensure that rain is not forecast for at least 2-3 days. 3. after 2-3 days brush off remaining moss and then clean brush to prevent transferring moss elsewhere. Repeat annually, or as required.

Q: can this be used to remove moss on my roof

It gets rid of moss on the drive so I think it would do the same on roofs. If the roof is sloping be careful where the liquid runs down. I’ve used it with a brush on fence panels as well as with a watering can on the patio, drive and stone garden ornaments. It’s good stuff!

Q: do i add water to product in pints please

I found the Jarder to work very effectively by diluting one part of the Jarder to five parts water. I suppose you could make the mix more concentrated by mixing one part Jarder to four parts water. So in answer to your question it is one pint of Jarder mixed with five pints of water. I used a garden spray to apply mine which worked very effectively.

Q: When is the best time of year to apply?

I don’t know if there’s an answer to that one. I guess you can apply it anytime. However, it’s pointless if it’s likely to be washed away by rain before it has had chance to work. Also, if it’s for getting rid of moss it’s probably best to wait until spring when the moss is at its worst after a damp winter. You can always do it again in late summer to try to stop some of the moss forming.

This works so well!

I initially used this product on my fence which had turned green. After a couple of days, I could notice the difference and after a couple of weeks, the fence looked like new. I have subsequently used it on the brickwork on my house and it has produced excellent results. Highly recommend!

Amazing product

We've moved into an older house and the fencing was pretty old and green with mould, debated replacing it all together but thought we'd give this a try and it got rid of all the green mould completely ! We had some patches on the patio too and it cleaned it right up ! Would definitely recommend this to anyone.
