what is the best way to remove moss from tarmac

There are many methods to remove moss and algae off tarmac. However, the best ones should be designed to address the root cause. This article will cover a few of these techniques, as well as HG Algae or Mould remover. If you aren’t sure which method to use, here are some common household items that can be used to remove moss and algae from asphalt.


Among the many ways to remove moss from tarmac, bleach is one of the most effective. However, it is important to mix the bleach properly, as dilute bleach won’t be powerful enough to kill stubborn spores. For best results, use straight bleach with a solution of 85% bleach. This solution will penetrate the pores of the asphalt, killing moss spores. This bleach mixture is inexpensive and easy to use. It is a great way to get rid of moss right at its source.

BAC 50 moss killer is the strongest available moss kill solution and is sold in professional strength. It contains 40% of Didecyldimethylammonium chloride. AlgoClear Pro is the professional version of the latter. Both contain the same ingredient, but the latter is only sold to businesses and tradespeople. However, BAC 50 is the cheapest solution by volume.

Washing powder is another effective way to kill moss. You can find biological washing powder in most garden centers. Sprinkle the powder on the moss with a spoon. Apply the powder on tarmac surfaces on a day of high rain chances. The water will activate the killing process, causing the dead moss turn brown instead of green. Next, use a stiff brush to remove the dead moss.

Another effective moss killer is ammonia. It contains copper sulfate and ferrous ammonium sulfate. One gallon of solution can be used to treat 1,000 square feet of asphalt. Use the product with care and wear protective clothing. It can cause skin irritation so make sure you use protective gear before applying this product.

Baking soda

A simple solution to kill moss is baking soda. Mix eight tablespoons baking soda with a quart water. Allow the solution to sit on the moss for 10 minutes. Then, brush off the dead moss. Repeat as necessary to remove the moss from your asphalt. You can also use dry baking soda, which works well on patio furniture and walkways. The baking soda should be evenly distributed on the area with a broom and scrubbed in.

Spraying a solution of one percent vinegar and nine parts water can also be used to kill moss. Apply the solution to the affected area and let it dry completely before washing it off. After a few days, scrub any remaining moss off the area with a stiff deck brush. You can also mix baking soda and water to make a paste to kill the moss if you don’t have a sprayer.

Another option to kill moss on asphalt is to apply baking soda to the underlying layer of the tarmac. To use baking soda as a cleaner, you should first soak the moss in water. Once you have applied the baking soda, wait for at least two days before rinsing it with a pressure washer or hose. After this time, you can apply a fresh layer of baking soda and rinse it off with water. This way, the moss will be dead and you’ll be able to enjoy the new asphalt again.

If you do not have access to a pressure washer or a garden hose, you can also apply household bleach. To remove moss from pavers, mix equal parts of household bleach with water. Mix the bleach solution and leave it to sit for about 15 minutes. Once the bleach solution has dried, you can sweep it away from asphalt or pavers. However, you should remember to use protective equipment, such as gloves, safety glasses and a filter mask.

HG Algae and mould remover

HG algae and mould remover is a powerful solution to the problem of moss on tarmac. It can effectively remove the growth within 36 hours. It works by penetrating deep into the concrete. For several months, the product prevents further growth of algae. This product is non-toxic and can be used on a wide variety of surfaces, including tarmac and concrete.

When the moss is still small, you can easily remove it using a garden hose or a power washer. However, if the moss is rooted deeply, you may need to hire professionals to do the job. Regularly washing the surface will remove dead moss and algae. You should also remember that moss can be brought in by plants and air and can rest on the surface.

If you need to quickly address the problem, a moss-removing spray containing HG algae and mold remover is a great option. Be aware that bleach can cause damage to driveways. Make sure that the moss has completely dried before you scrub it. You can also spray baking soda with bleach. These solutions are not as effective than HG algae or mould remover.

After cleaning the affected area, apply the HG alga and mould remover. This prevents any further growth and is extremely effective. Protective gloves and eye goggles should be worn before you use the product. You should also consider hiring a professional to clean the tarmac for you, as improper cleaning can lead to further property damage and increased health risks.

Sodium percarbonate

Sodium percarbonate, a powerful cleaner, kills moss by reacting to water and oxygen to create a bubbling liquid. The solution engulfs moss, killing its roots and spores and stopping re-growth. Because sodium percarbonate is made of only water and oxygen, it’s safe to use on a large scale without risking the health of the surrounding environment.

This solution doesn’t require water rinsing, which makes it a very safe solution for most types of paving surfaces. Sodium percarbonate reacts with water and begins to work as soon it is mixed. This cleaning solution is also effective on wood shake and asphalt shingles. To remove moss, you can use a mixture of 50 percent household strength sodium chlorite and water. Once the cleaning is complete, you can apply zinc strips to help prevent regrowth.

Before you apply a cleaning solution to large areas, make sure you test it on a hidden area of the pavers. Mix it with other chemicals to avoid chemical reactions. Also, make sure you’re wearing protective equipment, such as safety glasses, gloves, and a filter mask. Wear closed shoes, and be sure to ask for the advice of a professional before using any chemicals.

Besides using a moss-removal solution, you can also use oxygen bleach to clean hard surfaces. This is safer than chlorine bleach, and it won’t cause any color changes to your clothes or damage the plants around you. Another inexpensive solution to remove moss from asphalt is using vinegar. Vinegar contains acetic acid, which kills moss spores. Cleansing vinegar should be applied to surfaces using a 5% or 6% solution.


Bleach is the best way to get rid of moss from asphalt driveways. However, the driveway surface may be affected by the bleach. While the bleach will help to kill the moss, it can also make the driveway surface more porous. Bleach stains will turn yellow. A white vinegar solution can also be effective at removing moss from driveways. It is safe to use in any home environment, but it is best to follow directions carefully.

You can use a mixture of vinegar and 20 ounces bleach to remove moss from your driveway. This solution should be mixed with 5 gallons water. Then, apply it to your asphalt driveway. Let it work for around 15 minutes before you scrub. After that, scrub the area with a stiff push-broom or deck brush.

Preparing the driveway for bleaching is essential. You must first clean the area with a brush and water solution before applying the bleach solution. Use the solution as a solution and leave it on the surface for 15 minutes. To remove any bleach residue, scrub the surface once more. Once the mixture has dried, rinse it off with water. Do not forget to wear rubber gloves to prevent skin irritation.

Bleach is the best way to remove a thick layer of moss from a driveway. It can be used on asphalt as well as other surfaces. It is also safe and sustainable. You can also use baking soda or a garden knife to reach the areas between stones and asphalt. Apply the solution over the affected area and let it sit for at least 30 minutes. Then, use a scrub brush to scrub out the excess moss.
