Patio Magic! 16491 Concentrate: Ideal for Patios, Paths and Driveways (Kills Algae and Lichens), 2.5 Litres

Wish I'd taken before and after pictures! This did a great job. My patio area was really discoloured after the winter period with slippery green areas. Followed the instructions and poured this all over. I didn't use a hard bristle brush to work it in even though it says this is not nessasary. If it doesn't look like it's doing much after a day or so don't worry as it keeps working as the days go on. Our patio came up looking like new!

It does what it claims! Mild algae on block paving, gone overnight at 1:9 dilution with water. Patio needed stronger solution at 1:4 to kill thicker build up and moss and took a couple of days longer to do its job. Also cleaned algae from wooden fencing. Lost a star as it's a small container and at the stronger dilution doesn't go very far. I used a sprayer but with a watering can I would have struggled to cover the area needed.

Patio Magic! 16491 Concentrate is fantastic for keeping patios, paths, and driveways clean. Very effective and easy to use, it made a noticeable difference in no time. I’m so happy with the results that I will definitely be buying again and would recommend it to anyone looking for a reliable outdoor cleaner!

As a homeowner with a patio, paths, and driveway that were suffering from an unsightly invasion of algae and lichens, I was in dire need of a solution. Patio Magic! Concentrate proved to be the answer I was looking for. The first thing that struck me was the ease of use. The concentrated formula means a little goes a long way. I mixed it with water as per the instructions and applied it to the affected areas using a simple garden sprayer. The application process was straightforward, and I appreciated that the packaging provided clear guidelines on dilution ratios and safety precautions. The results were nothing short of remarkable. After just a few days, I began to notice a significant difference. The algae and lichens on my patio, paths, and driveway started to fade and eventually disappear entirely. It's as if the surfaces underwent a magical transformation. The cleanliness and visual appeal of my outdoor areas were restored, making my home look significantly more inviting and well-maintained. What impressed me even more is that Patio Magic! not only removed the existing algae and lichens but also acted as a preventive measure. Even weeks after the initial application, my surfaces remained algae and lichen-free. It's like a protective shield for outdoor areas. Another noteworthy feature is the product's biodegradable nature. I appreciate that it's not harmful to plants or pets, so I could apply it with confidence, knowing that my garden and furry friends were safe. The 2.5-litre container provides ample product for multiple applications, which is great value for the price. Given the results I've seen, I consider it a wise investment in the maintenance and longevity of my outdoor spaces. In conclusion, Patio Magic! 16491 Concentrate is a game-changer for anyone dealing with algae and lichen problems on patios, paths, and driveways. It's easy to use, highly effective, and provides long-lasting results. I couldn't be happier with the transformation it brought to my outdoor areas, and I highly recommend it to anyone looking for a reliable solution to revitalize and protect their outdoor spaces. This product lives up to its name, truly delivering "magic" for your patio and more.

Cleaned the patio well but needed to go over it with a jet wash afterwards to lift off more stubborn algae

It takes a few months to notice the difference, but it does work eventually.

I have a 12 sq metre, Indian Sandstone patio and have used Patio Magic on it about ten times or so over the last 3 years. It has never failed to clear the algae, except once, when it rained unexpectedly a few hours after I had covered the patio. By using the recommended 1-4 concentration ratio, I get three watering cans out of one 2.5 litre container. I use these three watering cans as one application for my 12 sq metre patio, (so one 2.5 litre container does me for ONE generous covering). If it has not rained for two days before and it is not going to rain two days after you put the PM onto the patio, there is not a problem. You simply pour the solution onto the patio and that is it. It does work when wet but I have found that it does seem to work better when it is dry. It also shifts stains left by the removal of patio pots and on my red brickwork which has plants hanging over it. If Patio Magic has not cleared any algae you might have within two days, try again with a stronger concentration. Stained brickwork or moss will take a bit longer. By way of comparison, I have also used Jeyes Fluid which says it cleans patios. You use the same 1-4 concentration as Patio Magic. You have to rinse your patio, apply the solution, take a hard brush and go over it, wait for 10 minutes, then rinse the patio again. I did this 3 times using progressively stronger concentrations and putting more effort in with the hard brush. But it did not shift even the easiest algae stains which Patio Magic generally clears in a day or two. Two quick warnings. I used my watering can to apply PM onto the patio but forgot to wash it out. The next day, I used the same watering can to water the geraniums and I killed them all, so it is worth washing the watering can after each application. When you cover your patio with PM, please think of our gorgeous garden birds who will think the puddles are water. Birds drinking any patio cleaning solution will suffer a painful death, so please could I ask you to be careful on behalf of our bird population which suffers so much anyway. I cover my patio after the birds have gone to bed.

Repeat purchase, Great job, spray and leave
