Patio Magic question

[peter2407]

Its that time of year again. I have a heavily stained decking area. I have sprayed/brushed on patio magic as today is a dry day. How long to leave it before hosing/jet washing?

 

[DannyB]

Don't! I was always told just to leave it to the sun and rain to let the patio magic work best. Jet washing will just wash off the patio magic. That's what I do and it seems to work.

I usually wash down first to remove all the surface dirt, then put on the patio magic and leave.

It should be applied to dry decks when no rain expected for a few days

It's been a bad winter for the green stuff.

In my case, even the tried and tested Patio Magic has struggled to keep my teak decks green free (applied end October as usual 4:1 mix).

I was given a strong recommendation for this product recently.

Don't think it's quite the same formulation as Patio Magic. Has anybody else tried it?

BTW (sorry for the drift) I was very impressed by this stuff for cleaning green and grunge off the coachroof.

Doing nothing is skill .
Similar product to patio magic applied over the boat and canvas by spray in early November and I haven't washed the boat since - only spot of green is a bit I must have missed. There is a light coat of dirt of course - but no green.

Reminds me of a quote ............. I had to look up who it was . Not Ronnie Barker as I thought but A A Milne.

Apply when dry. Leave for a week.
Rinse off with a hose.

Yes but it's no good putting it on top of grime - it only gets rid of the green, it won't dissolve dirt...

I use 'Wetandforget', Costco sell it in 5 litre bottles for about £20 and its labelled for Professional use only, so I imagine it's stronger than Patio Magic. I dilute it as recommended at 1:5 and use about 2.5 litres for my 37'. One coat gets rid of all the green in about a week, I usually give two applications about 2-3 weeks apart at the start of the season and one at the end.
This winter was the worst I've know for algae growth at Plymouth

I bought 5l of Aradet Bac 50 which is C10-C16 Alkyl Dimethyl Benzyl Ammonium Chloride (50%). This is basically super strength patio magic and I dilute it down myself (1l to 5.5l H2O). Works just fine. I think I've got enough to last a lifetime! The supplier is R&D Laboratories Ltd,Unit U, Enkalon Ind Estate, Antrim, BT41 4LJ, Northern Ireland. They posted it out to me, can't remember the price but works out much cheaper than patio magic.

Surprised that no one else seems to use Algon. About a fiver in Trago Mills for 2.5 litres, always does the job for me, have been using it for about 10 years. Cleaned my teak decks at the start of the year, applied Algon and they still look great, no green mould at all.

Unlike everybody else I rinse off my now-annual patiomagic application about an hour after applying. Start by wetting green and dirty decks on a dry day, apply around 5:1 patiomagic to the decks via one of those pump-up spray bottles from the garden centre, so I use hardly any of it anyway. Leave it an hour and then give the boat it's first scrub of the season with starbrite deck cleaner. Green stuff comes away with the Starbrite scrub and doesn't come back; decks stay algae free all season and as the mooring is at the shady end of the marina close to a line of trees I think that's pretty good.

Benzalkonium chloride is a surfactant so it will help

what's one of them?

And if you don't then rinse it off, it will just settle on the surface again leaving it dirty as it dries out...

If you say so.

I've often wondered. How do you manage to post on here without internet access? Sounds very economical. Please tell.
