Where mould/algal growths have turned black, in the worst cases this process can take several months.

The pigment in black mould can cause surface staining which will often remain even after the mould itself has been killed. Patio Magic will normally help to dissipate such staining over time, but may not completely remove the stains.

Liverwort : Patio Magic does not kill liverwort, which can easily be confused with moss and which often inhabits the gaps in such surfaces as block-paved driveways. We suggest treatment with Weedol Max which is available from garden centres and DIY stores.

Lichen : most lichens are extremely hardy. Though not designed for this purpose, Patio Magic will kill most lichens over a period of time, which may be anything from 2 weeks to 6 months. Thereafter, natural weathering will also take several months to remove the dead growths.

Patio Magic has a secondary slow-acting cleaning effect on most surfaces. This effect, which is helped by weathering, depends entirely on a number of factors including ; the porosity of the surface, the product dilution rate, the level of biological growth, exposure to the elements and the weather conditions. In most cases, for example an exposed non-shaded patio, the best results are often seen anywhere from 2-4 months after treatment.

Re-Growth and Maintenance

This also depends on the factors mentioned above.

As a guideline, we find that treated/exposed stone patios will generally be protected from re-growth for about 6-9 months after the first treatment, and often longer after subsequent treatments. Re-growth on wooden fencing will rarely occur within 12 months of treatment.

If the treated area is permanently shaded or collects water run-off, algal re-growth will be quicker.

Children: Patio Magic is non-acidic and contains no bleach. But, as with any household cleaner, please take normal precautions and keep our products out of reach of children.

Pets: as a precaution, keep pets and wildlife off the treated surfaces until they are dry (if they accidentally walk or sit on the wet surfaces, then promptly rinse their paws or fur in clean water). Once the surfaces have first dried after treatment, they will be entirely safe for pets.

Plants: do not splash or spray directly onto plants ; if you do this by mistake, then simply flush them with plenty of water.

Fish: do not allow any run-off into fish-tanks or ponds, or contact with any aquatic life.

Brintons Patio Magic is approved for use in Great Britain, Northern Ireland and the Republic of Ireland.

Please read all instructions and precautions on the product label carefully before use.

Is it OK for my children to walk on my patio when I’ve just used Patio Magic?

As a precaution you should keep your children (particularly if they are bare-footed) off the surface until the product has first dried. And, as with any domestic cleaner, always keep the container out of reach of children.
Please read all instructions on the product label carefully before use!

If I use Patio Magic on my patio, will it be safe for my pets and other animals to walk on ?

You should keep pets and animals off the surface until the product has first completely dried on your patio (this will often be about 4-5 hours). If they walk or sit on the damp or wet treated surface, then just wash their paws or fur in a little water. Once the surface has completely dried, it will be safe for pets and animals.

How about squirrels, birds and other wildlife ?

The risk of any danger to wildlife is very low. We suggest you discourage birds from drinking directly from the wet surface until it has first dried after treatment, and other wildlife from walking on it.
Do not allow any run off into fish-tanks, ponds, or contact with any aquatic life.

Will Patio Magic damage my grass and plants ?

It can do - therefore avoid spraying or splashing directly onto plants (particularly delicate ones) or grass ; if you do splash or spray them, then simply flush them with plenty of water. Hardy plants and trees will not often be affected, but you should nonetheless hose them down if you have sprayed them with Patio Magic by mistake.

There was some run off into soil by my patio and pathway – will it cause a problem ?

A limited amount of run off into soil will not normally cause any damage to plants, and the product will naturally biodegrade over a period. If a lot of the product, or diluted product, has run off into a patch of soil, then you can flood the area with water from your hose.

When is the best time to apply Patio Magic?

First of all the surface should be dry, otherwise the product will not be so effective.
The best results are obtained when the product is allowed to dry slowly on the surface. So, the ideal time is late afternoon or early evening, in overcast conditions. But you can apply it at any time.
It should not be applied if rain is expected in the next 5 or 6 hours, as it might just be washed away.

What is the best way to apply Patio Magic?

The most efficient and economic way to apply it is with a low-pressure (manual pump-action) garden sprayer ; this will allow you to spread it over the surface more evenly, and you will cover more m2 per litre.
It is even easier to use a watering can fitted with a rose, but you will not normally get such high m2 coverage.
Rinse out your sprayer or watering can after use.

Can I apply Patio Magic with a high-pressure sprayer ?

Absolutely not ! High pressure power washers can easily damage the surface you’re treating by removing a fine layer of the surface, and you should particularly avoid splashing any of the product into your eyes.

Does Patio Magic contain chemicals ?

Yes it does, in low but effective concentrations. Patio Magic is a broad-spectrum anti-bacterial and ant-viral disinfectant, a detergent, and has fungicidal/algaecidal properties. It doesn’t contain any bleach or acids and is very effective against mould, algae and mildew.

Does Patio Magic also remove Lichen ?

There are very many varieties of lichens (which are algae-fungi combination organisms). Although some are quite hardy, most will be killed by Brintons. Some dead lichens will not be removed by the elements.
Lichens can take many years to grow and are an important part of our environmental heritage ; as a general rule we recommend you don’t use Patio Magic on surfaces inhabited by lichens, unless they have become real eye-sores.

If the product is biodegradable, how does it continue to work for several months ?

In fact it is “readily biodegradable” according to OECD standards, which means that it degrades faster than just “biodegradable” products. Nonetheless, a very small and diminishing quantity of the detergent will remain absorbed, particularly on porous surfaces, for some time, and will continue its cleaning action and prevention of re-growth.
If the surface is continually wet, or where puddles form, then re-growth will occur much quicker.

How long will it take to work ?

There’s no clear answer to this, because it depends on a number of variable factors : the type and porosity of the surface, the type and level of the growth, the dilution rate, surface exposure to the elements and of course the weather conditions (frequent rain will help the detergent action). There are many millions of varieties of mould, mildew and algal growths and all will react in a slightly different way to the treatment.
Generally speaking the mould or other growth will normally be killed in 2-5 days. It will take longer for heavy growths.
Then the detergent action will slowly work for several months, and very often the best results will come between 2-4 months after treatment. But please note that if the surface isn’t openly exposed to the elements, the cleaning effect will be more limited.

My concrete path seems to have gone rusty-brown in patches. What’s happening ?

This is a reaction in the growth to the treatment, and the dead growths can be finely ingrained on the surface. As the mould is killed the detergent action will slowly react with weathering, and the discolouration will dissipate. This can take anywhere from days to (very exceptionally) several weeks, depending on how ingrained the dead growth is on the surface.

Can I use Pation Magic to clean my bird-bath ?

Yes : empty or drain your bird-bath and leave it to dry before treatment. After treatment, leave it for several days and then rinse it out thoroughly with water before re-filling and replacing it. Because the presence of water in bird-baths encourages rapid algal growth, re-treatment will often be needed more regularly than on other surfaces.

Can I use Patio Magic on marble ?

Delicate surfaces such as marble and alabaster : we suggest you treat a small discreet patch first. The deep veins of marble can contain green or black mould and, while there is a chance of discolouration of the mould after treatment, removal of the dead spores by weathering will not be possible in most cases.

What is the shelf life of Patio Magic?

The product has a virtually unlimited shelf life. If left outside the label and the liquid colouring may fade, but the product will remain effective for many years.

Can I use Patio Magic on swimming pool surrounds ?

Yes – but try to limit over-spray into the pool itself as much as reasonably possible.

What is the difference between Patio Magic and MMC-PRO ?

Both products should be diluted 1:4 (or up to max 1:9), but MMC-PRO is a more concentrated version of the product for use only by professionals and contractors. As a result the product generally provides an additional 2-3 months protection from re-growth.
