Rapid Application Moss Mould Lichen & Algae Remover
Rapid Application for moss removal, mould removal, algae removal & lichen removal is a sister product to the original blue Wet and Forget Moss, Mould, Lichen & Algae Remover. They have exactly the same active ingredient (unique to us) and will cover a similar area. It is only the faster application, using the revolutionary Reach Nozzle that is so different!
-
Rapid Application is non caustic and non acidic and contains NO bleach which gives it an endless shelf life.
- Rapid Application is safe to use on ANY exterior surface. ONE product to clean ALL exterior surfaces!
-
Rapid Application is your concentrate and garden sprayer all in one.
That means NO mixing! NO Measuring! NO mess! - The most outstanding feature of Rapid Application is its Reach Nozzle with its unparalleled reach of 8m or 2 storeys without using a ladder!
How amazing is that? You don't need a ladder to remove moss, to remove the lichen or black fungi from outdoor surfaces!
- For large concrete driveways, paths and more importantly, your roof - the revolutionary Reach Nozzle gives you an incredibly fast application - more than fifty times that of a garden sprayer.
IMPORTANT: You can't use regular Wet & Forget 5L (blue) with the Rapid Application hose fitting. It will NOT work as dilution rates are very different!!

FAQs and Guides
Will Rapid Application affect my pets?
Not under normal circumstances but normal safety precautions prevail. If they accidentally walk or sit in the product - wash their feet and bottoms with fresh water as a precaution.
If I am on tank water, can I use Rapid Application on my roof?
Sure can. But you must disconnect the water supply to your tank for 3-4 weeks or have at least 36ml of rain to remove the concentrate. Wet and Forget has been used for over 35 years to treat biological growth on roofs.
Do I have to use Rapid Application all at once?
No, but good planning is essential. Work to a pattern so you know where you have started and stopped. The product is fine if left in the spray container as it does not deteriorate when it has been diluted.
How long will Rapid Application last in the container?
Rapid Application has unlimited shelf life. Always the container out of reach of children.
How long does it take Rapid Application to work?
It is totally dependent on the intensity of the contamination. If it is really light you will see results within days. Otherwise it may take approximately 2-3 months to see improvements. Your concrete may turn an orangy brown when the Rapid Application is applied. This is normal and shows you have had a good reaction. The discoloration will dissipate over a short period of time and is not permanent. The good news is that when you use it again the following season, the clean up will occur within weeks. In the very worst case scenario where contamination is extreme, it may take 6-12months.
What is the coverage area of Rapid Application?
Every 2L pack covers between 100-300m2 depending on the porosity of the surface and the level of contamination. ie painted surfaces will use less product but porous surfaces readily absorb the product and therefore coverage could be in the range of 100-150m2.
When is the best time to apply Rapid Application?
On a cool, dry windless day and when no rain is expected for 4-6 hours. Often the evening is best when evaporation of the product is minimal. This will ensure that the surface to be treated stays wet with Rapid Application for an extended period.
Will Rapid Application damage my plants?
Not unless you are directly spraying it onto the plants. If you accidentally do this, then rinse the plants down with water from the hose. Or better still, protect them with paper or plastic to avoid overspray.
Will Rapid Application remove the mould off my timber decks?
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 of Rapid 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. Also check out our other product, Hit The Deck, for a more instant result (although it does involve more elbow grease!)
Will Rapid Application get moss out of lawns?
You will need to use Wet and Forget as the dilution rates are different. Firstly lightly water the lawn but not enough to saturate the moss. Do this late in the day when the sun is low so that evaporation is kept to a minimum. Dilute the 5L Wet & Forget 7 parts water to 1 part Wet & Forget and spot spray the moss. You may have to give it a couple of goes until you have it under control. At worst you may get slight burning on the grass but it will recover very quickly. Rake the dead moss out. then sprinkle lime over the area as this is usually a sign that your pH of the soil is not quite right.
How much Rapid Application will I need to clean my roof?
The average 3 bedroom tile roof is approx 150m2 but because of the undulations of the tile profile the actual area is a lot bigger. Therefore an average tile/concrete roof would require 2 x 2L packs, depending on how porous the surface is and how much biological growth is present. For an average 3 bedroom tile roof with lichen you would require 3 x 2L packs depending on the total area if it is covered with lichen. For best results, spot spray the lichen, leave for 10-15 minutes and then respray the lichen and the entire roof to ensure the plant absorbs the Rapid Application thoroughly. The first application is to dissolve the waxy surface. The 2nd spray will then penetrate the lichen.
For green moss and black mould, one application is normally sufficient. Your roof will normally take between 6 & 12 months to come clean. Again, this is totally dependent on how bad the contamination is.

Removing Lichen from any Exterior Surface
- Visually, section your area off into manageable parts.
- Spot spray the lichen within each section.
- Leave for 15-20 mins (while it is still damp) and then respray the lichen and the entire area of that particular section to ensure the plant absorbs the Wet & Forget/Rapid Application thoroughly.
- The first application is to dissolve the waxy surface.
The 2nd spray will then penetrate into the roots. - This will ensure much better results for you. Remember that it will still take time to decompose and break away.
