I know to leave a 1:4 mix on for a week, and apply with a sprayer, but .... Can it be applied when the surface is wet, and how long should be allowed before any expected rain?

How to Apply
(2.5 litre and 5 Litre Patio Magic )
The most efficient way to apply Patio Magic is with a low-pressure garden sprayer. You can also use a watering can fitted with a rose – this will be even quicker but surface-area coverage will be low.
Once applied, just leave the product to dry on the surface. Finish. Do not hose down the surface.
Please refer to Coverage Chart for dilution rates and surface-area coverage.
When To Apply
The surfaces should be dry before being treated.
Saturate the surfaces with the diluted products.
Do not apply the products if rain is expected in the following 5 or 6 hours.
The longer the product takes to dry on the surface, the better. To avoid rapid evaporation, Brintons should ideally be applied in the late afternoon or early evening.
Sensitive Surfaces
Discolouration : very rarely, some concrete and other hard surfaces may turn rusty-brown shortly after treatment ; this is a normal reaction to the treatment within the growths, and the discolouration will soon dissipate.
Timber (garden furniture, decking) : if the mould has been allowed to turn black and is deeply ingrained, the dead mould spores can easily be trapped by the fine wood splinters and removal by the elements may not be possible. You can help to lift the dead growth with a light brushing about 3-4 weeks after treatment, and we suggest you then re-treat the surfaces.
Marble : we don’t recommend use of Brintons on marble. Although our products will kill the mould and algal growths that often affect marble, removal by the elements of dead (and discoloured) growths in the veins will not be possible.
Terracotta pots : Patio Magic is an ideal algaecidal disinfectant for terracotta. The products will kill mould and algae on terracotta pots but, as when using other cleaners, a chalky residue may often appear on the dry surface. And, because of the extreme porosity of terracotta, re-treatment is likely to be required after a few months.

I found this on sale in the local hardware shop yesterday - so bought a container to try it out.
Is there anything on the boat it is not safe to spray it on? The instructions don't mention anything about canvas, ropes and so on.

No, it's fine on all that stuff. I mix a bucket of it up and chuck my ropes in for a week to get all the green out of the ropes. Works brilliantly.

I do similar with Boracol - works wonders on the ropes, also excellent on the canvas - paint on with a brush.

Spray is fine for patios. For a boat where presumably you don't want the stuff everywhere it is probably better to paint it on.

I brushed on Patio Magic to a sailcover and after an hour the green stuff was going, going, gone...
Aparently it rained later that evening but that was weeks ago and the green stuff hasn't come back! By the way, some of the diluted PM was splased onto the boat and 'magically' the green bits around the deck fixings also became clean of the afore mentioned green stuff.

no, it's safe. Really. Truly. Just read the MSDS about what it does to the bugs and beasties.

You're better putting it everywhere on a boat - anywhere that rainwater gets, which is where the green algae grows. It doesn't contain any bleach or acid so is as safe as anything.

Paint it rather than spraying - it is quite nasty for the environment, so you want to minimise run-off. Don't apply it if rain is expected over the next few days. Like Boracol, it will work better on teak if the surface is moistened every day to help it soak into the grain - this time of year is good provided there is a window of several dry days expected - you'll get a coating of dew every morning to naturally moisten the wood and improve penetration. In the middle of summer, you should mist it with water from a hand sprayer every morning for the first two or three days.

The joy of PM is how easy it is to use - I think you are making hard work of a simple job. I just spray it on with a garden spray bottle on a dry day, when rain isn't forecast for a few days. Takes me about half an hour and I don't revisit it. Did mine at the end of last season and the green is just returning in a few places where water sits. I'll do it again in the next couple of weeks and won't expect to touch it again until the end of the season. Keeps Treadmaster looking cleaner than anything else does.

All I'm recommending different to you is moistening it every day. In warm weather, it drys quickly and at that point it is effectively frozen on the wood till the next time it rains or you wash the boat at which point it gets washed off. If you mist it periodically (as is recommended for Boracol - which is effectively the same stuff), you give it the ability to sink deeper into the wood.

I am not sure that it gets washed off, I apply it with a garden spray (lightly) on a dry day, it soaks in to the surfaces and I forget about it, six months later the teak is still white. Great stuff, I wish I had discovered it years ago.

I poured it on (dilute) using a watering can with sprinkler to ensure a really good soaking. Had more control than a spray which can get blown into water unless windless day and does help to get it down reasonably quickly.

I spray it on my patio but have to be careful about ventilation because any small amount I inhale makes me choke, so I paint it on when treating my teak deck. I would advise being very careful when applying, especially about getting any inside the boat.

Great stuff. Maybe my sense of smell has gone as when diluted and either used in a garden sprayer on covers or with a watering can on teak it's the easiest thing in the world to use…

From past experience, I am afraid what you say will fall on deaf ears!
I pointed out the environmental damage it could do to marine life some months ago on another thread but nobody cares so long as it is easy to use and keeps their boat clean.

Hmm, I wonder if it can be mixed with a slightly water soluble paint... };0)
