Tarmac is one of the most popular modern materials in use today, often found across playgrounds, communal outside spaces, driveways, and pavements to name but a few uses. First and foremost, to clear up a common question. How do you remove moss from tarmac?

And while in terms of its structure tarmac is sturdy and reliable, with very few drawbacks attributing to health and safety, there is one big obstacle which can lead to safety challenges and most certainly has an aesthetic impact on the way the tarmac looks.
The growth of moss on tarmac is a problem which largely grows and expands with time; with the rough texture tarmac making it a breeding ground for moss and algae which thrive on damp surfaces which hold water.

Moss spores can set in the nooks and crannies across the surface of the tarmac, protecting them and allowing them to grow into established moss sites.
Removing or killing moss is not difficult – in fact, most of us do it regularly simply with the sole of our shoe or a high-powered hose. But how do we get rid of moss in the long term, and ensure it does not come back?

The process and Preparation

Step one calls for preparation – that is providing yourself with a clear surface on which to work your moss killer into the tarmac surface.

This is easily achieved with a stiff broom, brushing away as much debris and loose moss as possible so that you are left with a surface that is open to the spores and root growth of the moss.
You also want to ensure during the preparation step that you make sure your driveway or tarmac area has the sun shining on it as much as possible – not only does this help it dry more quickly after treatment, but it will also help in the long run by preventing the area from continuing to stay damp and wet.

Treatment – How do you remove moss from the tarmac?

Without getting into the complicated cleaning processes, this is where you have a couple of different options.

· The first option is to treat the area with a chemical cleaner and then rinse it away using a pressure washer. The treatment is designed to kill the root of the moss and algae, and the pressure washer is used to blast away the evidence and clean the surface of all moss spores.
As with any cleaning process, the drawback is that this option renders the surface hazardous until it is completely dry, and you will need to brush up the dead moss and remove it in order to ensure it doesn’t re-seed.

· The second option is much simpler but a little more of a long-term solution without the same satisfying instant results. This process involves spraying the surface with a long-term moss killer which will activate over the course of a few days – inhibiting regrowth and slowly killing the existing moss.

Removal and Maintenance for the Tarmac drive

This is where a professional will always win out over a DIY job – primarily because you can rest assured any decent professional cleaning company will remove the debris after the treatment.
After all, who wants dead moss knocking around across their driveway?!

And finally, to future maintenance. This will largely depend on the site you are treating, as a great deal of moss growth is born because of a damp and shaded patch of tarmac which is shielded from direct sunlight.

If you are able to cut back overhanging branches and trees to expose the tarmac to more sun then great – if not, a professional cleaner will be able to coat and treat the area annually with a moss killer to keep the problem at a minimum.
