    Getting rid of moss is simple with these super quick and easy steps. Read on and we’ll show you how to get rid of moss on paths and driveways with ease.

    1. 1

      Make a solution of 23L of cold water to 600ml of liquid bleach in a bucket

      Select your moss killer. You can buy commercial products but an easy homemade moss killer using diluted bleach to prevent discolouration is also a good option. Simply mix 23L of water and 600ml of liquid bleach, such as Domestos, in a large bucket.

    2. 2

      Add the solution into a spray bottle

      Put your diluted bleach solution into a spray bottle. A garden or backpack sprayer is your best option here for quick and easy coverage.

    3. 3

      Spray the solution onto the moss

      Spray the moss-affected areas. Make sure that there is full coverage to get the full effect of your homemade moss killer.

    4. 4

      Leave to soak for around 15 minutes

      Leave it to soak. When it comes to understanding how to get rid of moss on concrete even homemade solutions need time to work! For your bleach solution to fully kill off the moss it requires around 15 minutes.

    5. 5

      Remove the bleach solution completely with warm water

      Use clean, warm water to fully rinse the area. This includes any mossy areas you have treated. You need to make sure you fully remove all traces of bleach to ensure it doesn’t adversely affect the concrete, tarmac or another driveway surface.

    6. 6

      Leave for a few hours

      Leave it for a few hours. By the time you come back, you should find that the moss has been killed off. To be sure, check the colour. Dead moss will have turned a yellow colour.

    7. 7

      Use a hard-bristled brush to remove the moss

      Work methodically across your drive.

How to prevent moss coming back after moss removal

Now you know how to remove moss from tarmac and driveways, you can use these steps to avoid it returning:

  • ✦

    Test the soil pH level.

  • ✦

    Give your driveway plenty of sun. Driveways are often close to lawns and as moss loves acidic soil it's best to test the soil pH level. If your lawn’s pH level is below 6 use agricultural lime to control the acidity.

  • ✦

    Take care when washing your driveway. Moss survives best in areas of shade. A great way to ensure your drive and paths have plenty of sun is to cut back large bushes or overhanging trees. This will stop them from blocking sunlight.

You may want to clean your drive to keep it looking its best but damp, moist conditions are ideal for moss growth. Avoid flooding your drive and try to wash it during the day when the sun is out so it is fully dry before the cool evening.

Can moss damage my driveway?

Moss can potentially damage your driveway if left unchecked. Moss tends to thrive in damp, shaded areas and can quickly spread across the surface of your driveway. As it grows, moss can create a layer of moisture, leading to increased water retention and potential cracking. The roots of moss can penetrate and weaken the surface of the driveway over time. Additionally, moss can make the surface slippery, posing a safety hazard. It is advisable to remove moss from your driveway promptly using methods such as pressure washing, scrubbing with a stiff brush, or applying moss-killing solutions to prevent potential damage.

How to Effectively Remove Moss from Tarmac Surfaces

The sight of moss growing on tarmac surfaces is not only unsightly but can be hazardous, especially during wet or winter months. Moss absorbs moisture and can lead to slippery surfaces, which can cause accidents. In addition, moss left unattended can accelerate the deterioration of your tarmac driveway, causing damage over time. Therefore, it is important to remove moss as soon as possible to enhance the safety and longevity of your tarmac surface. In this blog post, we will walk you through proven methods of removing moss from your tarmac surfaces.

Pressure Washing: This is one of the most effective methods of removing moss from your tarmac surfaces. However, it is advisable to use a medium-pressure washer, not a high-pressure one, to avoid damaging the surface. You can also apply a moss and algae remover along with a biocide to the surface before pressure washing to enhance the effectiveness of the process. Be sure to wear protective gear such as gloves, glasses, and a respirator to stay safe during the process

Brushing with a Stiff Broom: Brushing the surface with a stiff broom can also help to remove moss from your tarmac surfaces. You can use a scrubbing brush or a deck brush to achieve the desired results. Be sure to apply some water and a biocide before brushing to enhance the effectiveness of the process. After brushing, dispose of the debris and rinse the surface with water to remove any remaining moss.

Chemical Treatment: You can use chemicals such as bleach, vinegar, baking soda, or proprietary moss and algae removers to eliminate moss from your tarmac surfaces. However, it is important to follow the manufacturer’s guidelines on the usage and application of these chemicals. Wear gloves and a respirator when handling these chemicals to avoid direct contact with them.

Hot Water Treatment: Pouring hot water onto the moss patches on your tarmac surfaces can help to kill the moss and loosen it for removal. You can also use boiling water with a combination of salt or vinegar for an effective and natural solution. Be careful when handling hot water to avoid burns.

Preventive Measures: Prevention is always better than a cure. You can prevent moss from growing on your tarmac surface by regular cleaning, trimming overhanging trees, and improving drainage. Additionally, it is important to keep the surface free from debris to prevent the accumulation of dirt and moisture.

With our top tips to remove moss from your driveway and learn how to prevent it coming back, you can keep your driveway and paths looking their best with ease.
