Ideally, remove any excess debris. We don’t recommend washing the surface prior to application as the product must be applied to a dry surface.

On a cool dry windless day, when no rain is expected for 4-5 hours. Often the evening is best when evaporation of the product is minimal. This will ensure that the surface to be treated stays wet and works for an extended period.

Once the area has been thoroughly saturate and dried. Leave the growth to start decomposing for 2-3 weeks (the longer the better!) then prior to painting or staining. The surface will also be sterile reducing possible contamination of the new paint with algae and fungi.

Once the surface is clean and dry, you can paint or stain over the area and this extending the life of the painted surface as it not only removes moss, mould, lichen and algae, but also the surfactant action helps remove dirt and other residue that could cause fading or chipped paint. Spraying your outdoor house surfaces annually will extend the life of your paint and keep paving looking fresh and new.

Our product doesn’t contain bleach or ammonia but animals must be kept off the treated surfaces until dry. If your pet accidentally walks or sits on the treated surfaces, wash their feet and bottoms with fresh water. Subsequent rainfall poses no issues to your pets.

Our aftercare to ensure no damage is done to any plants is to rinse them with water from the hose when we have finished the treatment(s).

How long it takes to work is totally dependent on the intensity of the contamination of mould, algae or lichen. For mild contaminations, results can be seen in days. For more stubborn infestations can take approximately 2-3 months to see improvements. In very severe cases of contamination it may take 6-12 months to work. The good news is that when Moss Ninja is called again the following season, the clean up results will occur within weeks!

Most definitely! But if your deck is older and has never been cleaned, it may be noticeably blackened with the contamination. In this case, it would be advantageous to wait a month after the application and give the area a light brush with a broom or scrubbing brush with warm water to remove it. The good news is that you should only have to do this once and then the maintenance becomes so easy.

Absolutely! To remove moss on grass first water the infected area lightly being sure not to saturate the moss. Do this late in the day when the sun is low so that evaporation is kept to a minimum. At worst you may get slight burning on the grass but it will recover very quickly. It may take a couple of goes until you have the contaminated areas covered. Give the treatment some time to tackle the moss and then rake the dead moss out. To help your grass recover from the moss infestation provide the area with garden lime to change the ph levels. If it's early spring or autumn, overseeding and fertilising should do the trick.

Depending on how porous the surface is, you may need to apply more often. It’s worth checking the surface for any signs of regrowth regularly, especially during the wetter, colder months. For most applications, once per year should suffice.

The major advantage of using our services is there is no damage to the surfaces treated and our method is kind to the environment. Common cleaners containing bleach can often damage surfaces, but we use a product that contains no bleach, ammonia or harmful chemicals. Some of our ingredients remain active on the surface killing any new spores that might arrive preventing regrowth. Once we have applied our product to your required areas, the wind and rain will interact with our ingredients and over time leave your outdoor surfaces looking like new!

The product we use at Moss Ninja is extremely versatile and can be used on all kinds of outside surfaces. For a full comprehensive list of the areas that Moss Ninja treat please click here.

The product we use contains no bleach, ammonia or harmful chemicals so we can happily treat your surfaces knowing that no damage will be caused. On first application the product may turn concrete an orangey brown colour. This reaction is completely normal and shows that the product is doing its job! The discolouration will dissipate over a short period of time and is not permanent or harmful.
