Patio Magic

[SimbaDog]

Purchased some today for my teak, do I need to spray it on when it's dry & no rain forecast?

 

[sailorman]

Hot n sunny is best but you may have to wait a while :nonchalance:

 

[photodog]

Just lather the stuff on.... It's best if it doesn't rain for a while... Don't feed any to fishes or other water stuff.

Apply when dry and no rain for 24 hours. I use it on canvas and ropes and apply it with a brush - much more controlled than a spray.

Thanks :encouragement: Presumed that was the case. Never tried it before.

It's brilliant at stopping stuff turning green and gets rid of any green that's there. Just brush or spray it on and leave it to dry.

+1 Brush does the job with minimum waste (aka polution)

it is rather toxic to water-living animal life. Have a look at the MSDS.

That said, used carefully.....

Surely Patio Magic should be kept well away from aquatic life? If you use it on a boat it will end up in the sea and .........just read the label

not benzalkonium chloride

Tankers use a contact biocide with limited dispersion characteristics, so that the A/F lasts 4 - 5 years.

Drops of Patio Magic, or wash-off from decks and ropes will disperse freely in water and kill aquatic organisms by, basically, causing the cells to leak.


Benzalkonium chloride is a useful chemical e.g.

It is used in:

hand sanitizers
skin antiseptics
throat lozenges and mouthwashes
spermicidal creams
treatments for herpes, cold-sores
hygienic towelettes and wet wipes
spray disinfectant
algaecide for clearing of algae, moss, lichens from paths, roof tiles, swimming pools, masonry and in horticultural greenhouse disinfection

BUT it is highly toxic to fish (LC50 = 280 μg ai/l), very highly toxic to aquatic invertebrates (LC50 = 5.9 μg ai/l), moderately toxic to birds (LD50 = 136 mg/kg-bw), and slightly toxic to mammals (LD50 = 430 mg/kg-bw).

in the case of aquatic invertebrates, that means a small crab weighing 10g (about 2oz) will die if it is in contact with about 2 millionths of a gram of the active ingredient of benzalkonium chloride. The LC50 rating is that at least 50% of them will, anyway.

But it will keep your decks clean I suppose you could try washing down with plain sea water more frequently.

I am only going to spray the boat with 25 litres of it so should be OK

Don't you understand? It dries in the teak and never ever comes out, ever...and you can ignore the bit on the instructions about not using it near aquatic life, that just concerns pond 'n fish tanks apparently.

At least that's what I read on this forum....so it must be true.

But hey as you say, at least you'll have clean decks.

Got some to use on the toerail and other greening bits on Storyline but after reading the warning label I did some research online and then did not have the heart to use any. Does anyone know if it is any more/less toxic than boracol which is supposed to do a similar job ?

Also fwiw, it is very toxic to cats so be careful if you use it at home.

NOt sure if you have come across Wessex Chemicals two part system? I have never used Patio Magic on Teak as the WC system is so effective and harmless to aquatic life. Only ever put it on the canvas green bits, well watered down and allowed it to dry in - works great all season.

double post.

Used at recommended concentrations, Boracol and Patio Magic probably have similar levels of benzalkonium chloride. Boracol's main chemical ingredient however is disodium octaborate, which is a powerful fungicide. It's this which helps keep teak looking clean, as much of the apparent "dirt" on teak decks is in fact tiny specks of fungal growth.

Boracol contains ethylene glycol as a carrier, which helps to ensure good penetration into the teak. Carefully applied, when rain isn't likely for 24 hours, the likelihood of a significant amount of benzalkonium chloride being washed into the sea is minimal.

Be careful if spraying. It is quite nasty stuff and may cause breathing problems if inhaled. I prefer to use a brush when applying it.

Yes, have got the two part system and it has been great on the handrails but the plan was to use the patio magic first on the toerail.

This sounds like the definitive answer and the best way to go imo

"Carefully applied, when rain isn't likely for 24 hours, the likelihood of a significant amount of benzalkonium chloride being washed into the sea is minimal"

I'd like to see the basis for that hypothesis and a definition of "minimal".



By chance my HSE users' committee posting today included this wee document:-

Our friend, benzalkonium chloride, features in it around p30 !


What is really exercising the minds of the environmentalists in EU is the use of nano materials, even from such materials as human cosmetics and some weedkillers.
