How to get rid of green film from paving stones and patio? Effective methods

Annoying green cover such as algae, moss or lichen will grow on almost any surface under the right conditions. Over time, airborne particles such as dust and dirt combine with the sand in the joints to create an ideal place for green cover to thrive. Shady places, damp conditions, humid areas and prolonged periods of wet weather accelerate growth. The best way to get rid of green growth is to be proactive and remove it early. Below, we’ll give you a few tips on how to remove green film, whether it’s from stones, pavers, outdoor furniture or a patio.

“Green plaque” is usually a combination of algae, mosses, and/or lichens: Algae and mosses are plants that we generally don’t appreciate. They form an unsightly coating by spreading wildly and uncontrollably. Green coverings should be removed because they can cause slippery floors when wet. In addition, it should be mentioned that over the years it decomposes the surface of the material.

Here are some steps you can take to limit the growth of green cover:

1. keep your patio or walkway clean. Make sure dirt, leaves, mulch or debris do not accumulate. Clean the surface weekly with a broom or blower.

3. Remove any new moss quickly. As soon as you see a greenish growth, remove it. If left unchecked, it will grow quickly and take root in the joint sand. Once this happens, removal is more difficult and time consuming. Sand could then also be reduced when removing the green cover, and new joint sand will need to be added.

If you discover green cover on your paved surfaces, you can often combat it yourself. The goal here is to remove it from the surface without affecting the polymer sand in the joints. To avoid damaging the joints, you should complete this task on a day when the surface is dry and the sand is firm.

With the last few weeks of the cold season flying by, early March is a good time to start cleaning your patio before spring. But what should you use? The following common household remedies can get rid of moss, algae, lichen and other fungi in just a few minutes.

Removing green growth with vinegar

White vinegar is great for removing stubborn dirt and household stains and can even be used in your garden.

This eco-friendly solution should be made with equal parts white vinegar and water to correct discoloration and remove stubborn stains. First, move all plants and furniture out of the way before sweeping the area to get rid of the green buildup. Use a weed removal tool to remove weeds from the patio before you begin cleaning. Mix the 50/50 solution in a large watering can and generously apply the liquid to the green cover.

Let it sit for 20 minutes. Although 20 minutes may not seem like a long time, this naturally acidic solution works wonders on stubborn dirt and deep-rooted grime. Use a clean garden brush to sweep away the solution. Pour some additional vinegar on any remaining weeds to kill them naturally. Wash the patio with clean water to remove any remaining residue.

Especially in spring and summer, many people choose to use a pressure washer to clean pavers. Unfortunately, there are two major drawbacks. First, it rips the grout out of the patio tiles, which can cause the tiles to shift. Second, the pressure washer could damage the tiles, making the structure of the tiles more porous, which will lead to green coverings penetrating deeper into the tiles. And that will cost you even more time and energy the next time you need to clean the tiles.

Beautify your patio with baking soda
