If you were wondering what moss is, you have come to the right place. Moss is part of the plant family called “Bryophytes”. The resilient plant has existed for millions of years. Moss is a rootless species and it does not grow wood or flowers. Many plant species produce seeds for reproduction however moss produces spores. Spores are a cell that certain fungi, plants and bacteria produce. 

Moss can be found in all sorts of habitats, it has spread around the globe within its millions of years of existence. Some of the places you can find moss are:

  • Rain Forests
  • Wetlands
  • Gardens 
  • Caves
  • Urban Areas (Driveways, walls and pavements)

One thing these different environments have in common is that they all have tendencies to harbour dampness and moisture which is what allows moss to flourish in terms of growth. Moss will not grow well in dry conditions due to the lack of water.

When it comes to concrete floors it is very common for moss to grow. Especially if the surface is fairly moist and slightly shaded throughout the day. These are the perfect conditions for moss to grow. It is vital that moss is maintained as it can become a slipping hazard. This is because moss can make walkways and paths dangerous to cross. 


Remember that before removing moss from concrete floors, it is important to take the necessary steps to prepare the concrete. This includes sweeping the area, preparing the correct cleaning solution, scrubbing the area after application of the solution, and rinsing the area. Be prepared to repeat this process a few times until the moss is completely removed. This can often be a time-consuming process but with the right tools and techniques, you can restore your concrete floors to their original condition.

Once this method is used, after about 24 hours the moss should die and turn orange or brown. When moss is in this condition it makes it easier to remove with a metal rake. 

When growing, moss roots grow very shallow, so raking will become more simple to remove the whole plant. Once you have collected the moss, you should dispose of it in sealed bags away from your lawn. 

Killing the moss is one step, but keeping it from growing again is another. This can only be done by changing the conditions in your lawn that led to its initial growth. The growth of moss isn’t necessarily determined by the condition of the soil. But, moss is an indicator of some soil problems.

This is the method you need for the driveway as this ensures 100% of the moss is killed and stopped from growing again in the future. 


Sodium Percarbonate is amazing at breaking down single-celled organisms like moss as it only includes water and oxygen indicating it does no damage to the environment. 

This is a process that occurs once Sodium Percarbonate has been applied to moss.
