How do you use Patio Magic - dilution, rinse, scrub etc?

PM doesn't seem to do anything to waterproofing.

Examination of label will confirm whether they are the same thing.

Some mould killers are bleach based which I suspect will not be good for fabrics or line.

That Wet & Forget claims to not contain bleach - I guess it is very similar to Patio Magic (and Boracol). I doubt it damages proofing - when we apply Patio Magic or Boracol to our canvas, we usually follow up with an application of Fabsil to the seams and other stitching a week or two later.

Countless threads on here extoll the virtues of Patio Magic so I went out and bought some; needless to say it doesn't tell you how to clean spray hoods and ropes with it!

So:-

Do you dilute it?
Do you thoroughly wet the item or just spray it on
Do you need to scrub as well
Do you wash (e.g. ropes) before or after application or not at all
Do you rinse off afterwards
Instructions say it takes several days to work on a patio - do you need to keep it from drying out?

Any other hints and tips>

It doesn't clean anything, just stops it going green in the future.

Not true! It does not clean in the same sense that soap and scrubbing does, but almost all the discolouration of teak decking is due to mould growing in the grain. Things like Patio Magic and Boracol kill that mould which then washes out completely naturally with wind and rain. Our deck was looking very discoloured - I applied a coat of Boracol and waited - a week later it was looking a lot cleaner and three weeks (and a couple of heavy showers) later, it looked like new.

I was applying some Patio Magic to an area of our side deck that was beginning to go a bit green a couple of months ago and mixed up too much of it. I was left with a large cupful to get rid of and was going round to the marina facilities block to pour it down the sink. On my way round, I met a friend who has a yacht about 15 years old. The deck was looking very tired - he has always been very dismissive of chemical treatments and scrubs the teak aggressively with the result that the grain is now pretty damaged. I asked him if I could use up this cupful of PM on his side deck and brushed it over - a couple of weeks later he came round asking what on earth it was because that couple of square feet of deck was now spotless and he wanted to treat the rest of the boat!

I bought some Patio Magic a year or so ago, damned if I can remember where I put it! :nonchalance:

It's not very expensive! Boracol seems to last longer, but is several times the price. Boracol has two ingredients - one is fast acting and short lived, the other is slower acting and longer lived. Patio Magic only has the first one. I do prefer Boracol - it's what Halberg Rassey and X-Yachts recommend - but it is so much more expensive that I can apply three full coats of Patio Magic and still be in-pocket.
 
No one is bothered by this when they are splashing it on their canvas and/or decks..............

In the dilutions and amounts used it pales into insignificance next to anti-fouling or cleaning products in grey water...

Read back - I certainly don't agree with "splashing it around" - I apply in a very controlled manner using a brush and only when rain is not forecast for several days. I don't think spraying is a good idea, but I do tend to get jumped on when I dare to suggest that spraying is a bad idea.
 
I've reminded my self now.
what i'm talking about I guess is , is Patio Magic the same or similar to generic brick cleaner ?
I have some and wondered if i could use the brick cleaner on my patio as well as using it on the boat to dissolve beasties on my prop ?

Ah, I would be very careful of anything labelled "Brick Cleaner" - some products by that name are very strong acids and will do serious damage to most things they touch.

Patio Magic contains Benzalkonium chloride which is a good mould killer but not at all corrosive and not particularly harmful to most animals - if you have squirted drops up your nose, or into your eyes recently, you will have been applying it - admittedly in low doses. It is not good for microscopic marine life, so it does make sense to minimise the amount that you let leak over into the marina

Great post, as ive been looking into using patio magic on our canopy for the spring clean. I assume it doesn't cause damage to the canopy windows if you ended up getting a little bit on them ?

Honestly, no - it is very mild on all surfaces. Try to avoid long term contact with your skin - it can be a bit irritant. When I first did our deck, I made the mistake of kneeling on a damp patch of deck and didn't change my trousers - my knee was red the next morning.

That's the problem with wearing red sailing trousers, never did see the point of them.

I used some last year, using the dilution that my neighbour in the marina had used. Sprayed it on using a garden insecticide sprayer and diluted, I think, 3 parts water to 1 part patio magic. Left to dry for 48 hours and then scrubbed / washed off. The result was OK and a big improvement on what it had been but still not perfect.
At SIBS last year I arranged for Arun Sails to take my sails, spray hood and cockpit enclosure for valeting and the covers to be reproofed. Certainly more expensive than patio magic but the result is fantastic. They did some minor repairs to both sails, restitched parts of the spray hood and enclosure, put new clips into the spray hood as required and it all looks as good as new. Definitely money well spent and the way I will do it in future.

Apply 3 or 4 to 1 when weather is dry for 24 hours at least. Just spray on and LEAVE. Do not wash down ever. The rain will take it off along with fine brown powder. It goes on working if using on teak deck and gets the mildew out of the grain giving a light wood colour that does not get so hot in the sun.

a better product for wood is Britons mmc plus, by the same manufacturer. MMC - moss mould cleaner

Strangely, I have used this product on my patio of all things. I used it at 4:1 and sprayed up to a wrought iron gate. I ended up with lovely clean slabs in the back garden with clearly defined line under the gate to the horrible green slabs at the front. I've done the obvious now and await as they start to match.

I sprayed the timber on the boat at the last visit (however toxic, you don't let much get away; hardly any hit the ground!) and came home. Looking forward to the results at my next trip. Thanks to this thread for the reassurances about no damage to materials; I sprayed inside too and will got some on the lining.
