How to permanently remove moss from concrete? Moss is a common problem on concrete surfaces, especially in shady or damp areas. While it may look decorative, moss can actually damage concrete if left for long periods of time.

What’s more frustrating, is moss tends to grow back even after you’ve spent all that time scrubbing and cleaning the area! This is because many people mistakenly believe that you can just pull out the moss with your hands clean the area and you’re done.

But in reality, it’s not that simple! Moss thrives because it does not need to be rooted in the ground, like weeds and other plants. Not to mention, the fact, that moss is able to spread by releasing spores, and each spore can grow an entire colony.

Fortunately, however, there are a few effective ways to remove moss from concrete “permanently” So, if you’re tired of fighting a never-ending battle against moss, here are 7 Ways To Permanently Remove Moss From Concrete.

7 Ways To Permanently Remove Moss From Concrete

  1. Moss Killer
  2. Mold Remover
  3. Bleach
  4. Vinegar
  5. Baking Soda
  6. Boiling Water
  7. Pressure Washer

The first step is figuring out what type of moss you have growing on the surface? If it’s a thin layer, for example, then all you need to do is use an Acid-Based Cleaner.

One product we recommended is the Wet & Forget – Moss Mould Lichen & Algae Remover this is a very powerful mold stain remover.

Thicker types of moss on the other hand will require other methods to permanently remove it from the concrete! Some moss may be tougher than others, so it may require repeat treatments.

How To Remove Moss

1. Moss Killer

The best way to kill moss on concrete is by using a product that’s designed to kill the moss including the spores so it can’t spread and grow back.

There are a few moss killers on the market, but we recommend using a non-bleach formula like the SmartSeal moss killer and Algae Killer as this won’t stain, nor will it damage your lawn if you’re cleaning a pathway close to your grass!

How To Apply:

The best time for applying Moss Killer is early spring, however, this product will work no matter what time of year it is! Moss Killer works best when applied before the moss has grown out of control. But, for best results, you should apply it in dry weather.

  • The best way to apply moss killer is to spray the entire area with this solution and leave for at least two hours, after this time you should start seeing the moss turn yellow.
  • After a couple of hours, the dead moss can be washed away by hand or by rain! Depending on the size of the area your moss killer should be able to do this in one application.
  • If this is not the case, then we recommend a moss killer called “Smartseal Moss Cleaner” which is perfect to use on Roofs, Driveways, Patios & Walls.

2. Mold Remover

Another great way to permanently remove moss is to use an acid-based cleaner mold removal, also known as mold remediation, mentioned earlier. This is good for using on roofs, walls, patios, or even block paving.

What’s good about mold remover is they are Bleach-free, which means your not using any harmful chemicals that could cause harm to your surrounding plants or grass!

How To Apply:

  • When using an Instant Mold Stain & Mildew Stain Remover you will want to make sure the surface is cool to the touch and free from dirt, grease, or wax.
  • You can use a brush, roller, or pump sprayer to apply it evenly across the surface. You then leave it for 15 minutes so that it can start working on breaking down the moss.
  • After 15 minutes using a garden hose or a pressure washer rinse off the area until all evidence of cleaner and moss has been removed. If there is still some residue left behind, repeat these steps until gone!

Although we have provided some directions, when it comes to using a mold remover, it’s very important that you still read the instructions very carefully as these solutions are very powerful!

3. Bleach

Using bleach to remove moss is another good option, however, it’s also a strong chemical that will not only remove the moss from concrete but, could also end up harming your plants if your are not careful so you need to apply it with care.

Bleach is effective in killing moss but can also be harmful to the environment, so use it with caution! and watch out for any surrounding plants. One bleach we recommended is the Simple Green Oxy Solve Total Outdoor.

How To Apply:

  • To start make sure you clean the area you want to treat. Then mix the bleach with 1 part Oxy Solve with 20 parts water in a bucket.
  • Leave the bleach for a couple of minutes, then using a hand brush give the mossy areas a good scrub until it’s all removed.
  • After scrubbing, rinse off the area with a pressure washer (or garden hose) until all evidence of bleach and moss has been removed.

You can also use this method to clean driveways, sidewalks, or any other concrete surface! Just remember like all chemicals make sure you always read the instructions first and take the necessary precautions.

4. Vinegar

So why would anyone think that vinegar could kill moss? Well, in fact, vinegar contains acetic acid which is an effective way to kill moss on stone or other hard surfaces.

Vinegar works very similar to most Commercial Moss Killers and will kill it within a matter of hours, and again you will notice this when the moss starts changing color and goes yellow.

How To Apply:

  • The Calyptus 45% Pure Super Concentrated Vinegar is perfect for removing moss and is Highly concentrated and very powerful.
  • It can be diluted up to 1:8 with water or used at full strength. For light moss growth, we recommend a dilution of 50:50 vinegar with water.
  • Spray the mixture onto the mossy areas and leave for at least 15 minutes. This will give the vinegar time to work on breaking down the moss.

Important: If you have pets that go outside make sure they don’t have access to the area until the vinegar has been rinsed off completely as it can be harmful if ingested!

5. Baking soda

Baking soda is another great option that works to deplete the acidic levels in your garden, which will stop moss from growing on any surface.

  • A good mixture would consist of about one tablespoon of baking powder and a gallon of water mixed together before being sprayed onto wet or dry surfaces where you want it removed for an instant result!
  • You can also mix equal parts vinegar with baking soda (about half a cup each) then apply this gel-like liquid directly over top of all areas affected by Mossy Growths as well.
  • Just be sure not to get too close if using Vinegar based because while they work very similarly when applied correctly both have different dangers associated so always use caution whichever method is chosen. 

6. Boiling Water

Using boiling water is another way that can remove moss from concrete. This method is more gentle than the others and has no chemicals involved, so it’s a good option if you have plants on your driveway or porch.

Be sure that all areas are free from any other obstructions before beginning this process – such things will only make removing moss growths much harder.

How To Apply:

  • Take boiled water in an open container with about one-gallon capacity be careful not to spill onto hand when pouring.
  • Pour over the moss until wetted completely through then wait approximately 15 minutes during which time steam heat generated should kill of the moss
  • Boiling water is a simple and effective way to kill moss without using any harmful chemicals!

7. Pressure Washer

A pressure washer is a powerful tool that you should always wear protective gear before using it, this could include rubber gloves and safety goggles.​

How To Apply:

  • It’s a great way to remove moss from concrete as it quickly and easily blasts the dirt and debris away.
  • This method does use water, so be sure to check your surroundings for any valuable items or plants that may get wet and damaged in the process.
  • When removing the moss you need to watch out for spores, they can easily snap away from the main plant and contaminate the ground and other surfaces.

Pressure washers should be used only as a last resort or as a finishing touch because they require much more caution while using than any previous method mentioned.
