Patio Magic! Concentrate: Ideal for Patios, Paths and Driveways (Kills Algae and Lichens), 5 Litres

Product Information

Put it another way; Patio Magic will kill whatever is growing on your patio and ruining its appearance, but based on the results of my testing, it won’t remove it. Patio Magic! makes light work of the hardest of jobs, and is suitable for use on patios, driveways, masonry, greenhouses, fences, and a large variety of other hard surfaces (see below) A5: Protection can last for about 6-9 months after the first treatment, subsequent treatments can help extend the length of protection. Areas permanently in the shade, or prone to collecting water will have a reduced period of prevention. Some products may be delivered straight to your door from one of our suppliers and these products will be labelled within the product description.

DIY Gardening tested Patio Magic in April 2022 on a concrete slab that was dirty and had lichen growth on the surface – this is common and found on most external hard surfaces and is what makes them look grubby. As you can see from the before and after photos, Patio Magic does work, but only if you’re very patient. Antibacterial - This patio cleaner does the job effortlessly with no need for any bleach or acids which is great for if you have children or pets.

If you want to seal your patio, you’ll need to power wash it first to completely remove any contaminants before the sealer is applied. A4: The primary function of Patio Magic! products is to kill green mould and algae and lichens you will normally see the results of this within 2-4 days. Some lichens can be very hardy and results may take longer.

Based on my experience, mould, lichens, moss, and other similar organic matter won’t start to regrow for at least a year and possibly much longer if the patio is located in a sunny spot.

It reacts with other chemicals, where it can give off fumes. It can’t be mixed with weedkiller for example. Unlike Patio Magic, in my tests, I found that this chemical will dissolve the organic matter growing on the patio and in many cases, it got get rid of it in less than an hour. The ready-to-use version doesn’t go very far and costs much more per square metre but has the advantage that you don’t need to mix it with water. Patio Magic kills and controls green mould and algae and is a dynamic algaecidal detergent which works without the need for manual scrubbing or pressure-washing
