How much area does Wet & Forget Rapid cover?

Every 2 litre pack will automatically mix water from your garden hose to get coverage of 200 square metres in 10 minutes. Some surfaces e.g. painted surfaces will use less but porous surfaces readily absorb the product and therefore coverage could be in the range of 200 square meters.

Can I change the specified ratios given in the instructions?

No. Wet & Forget Rapid Sniper Nozzle is designed to mix the perfect ratio of 'Product to Water' for you everytime regardless of water pressure. It will deliver the perfect solution for all outdoor surfaces from the simplicity of your garden hose.

What outdoor surfaces can Wet & Forget be used on?

Wet & Forget can be used on an extensive range of outdoor surfaces including tarmac, concrete, decking, roof tiles, Artificial Grass, Astroturf, bowling greens, bricks and paving, canvas tents, caravans, static caravans, caravan awnings, motorhomes, conservatories, fibreglass boats, greenhouses, golf greens, limestone, sandstone, marble, outdoor furniture, outdoor pots, outdoor painted surfaces, pool surrounds, shade sails, slate, solar panels, tennis courts, yacht sails.

Should I sweep or wash the surface before applying Wet & Forget?

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

When is the best time to apply the product?

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 with Wet & Forget for an extended period.

Can I paint or stain over Wet & Forget?

Once the surface is clean and dry, you can paint or stain over Wet & Forget. Wet & Forget is great for 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 with Wet & Forget will extend the life of your paint and keep paving looking fresh and new.

How soon after applying Wet & Forget can I start painting?

Thoroughly saturate the surface with Wet & Forget on a cool, dry day. Late in the day is best. Leave the growth to start decomposing for 2-3 weeks (the longer the better!) then prior to painting or staining, gently pressure wash the surface - growth, dirt and residue will come off faster and easier. The surface will also be sterile reducing possible contamination of the new paint with algae and fungi.

Do I have to use it all at once?

No, Wet & Forget is fine if left in the spray container as it does not deteriorate or go off when it has been diluted. Plus it will not damage your garden sprayer as the product is not corrosive.

Will it affect my pets?

Although Wet & Forget doesn’t contain bleach or ammonia we recommend keeping your animals off the treated surface until it is dry, to ensure they don't ingest any of the product. If they accidentally walk or sit in the product wash their feet and bottoms with fresh water as a precaution.

Will it 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.

How long is Wet & Forget's shelf life?

Wet & Forget has an unlimited shelf life so it will last forever in its container! Natural light does not damage the efficiency of the product. For safety, always keep the cap on tightly and the container out of reach of children.

How long does Wet & Forget take to work?

How long Wet & Forget 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 Wet & Forget 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 Wet & Forget is used again the following season, the clean up results will occur within weeks!

Will it remove the slime 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 Wet & Forget 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.

Can I use Wet & Forget to get moss out of my garden grass?

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.

Dilute the solution using 7 parts water to 1 part Wet & Forget formula and spot spray the moss. It may take a couple of goes until you have the contaminated areas covered. Give Wet & Forget 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.

How much water should I add to Wet & Forget before application?

Wet & Forget RAPID Application mixes with water automatically for you from the garden hose regardless of the water pressure in your area.

How do I apply Wet and Forget RAPID APPLICATION to a surface?

Wet & Forget RAPID APPLICATION simply plugs onto your garden hose and automatically mixes the water for you regardless of water pressure in your area. There is a nozzle attachment you can swap around to give you a wide FAN spray to cover large flat areas rapidly or swap it around to create a SNIPER Jet that can reach up to 8 metres. This is great for reaching high areas from the safety of the ground.

When should I apply Wet and Forget to a surface?

If you are applying Wet and Forget to an outdoor surface such as a patio, deck or driveway, always do so in dry conditions. Applying the solution in warm, dry weather when it hasn’t rained for several days. If it rains 4-5 hours after you apply the Wet and Forget, you will need to reapply once it is dry again.

How often does Wet and Forget need to be applied to surfaces?

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

What are the benefits of using Wet & Forget?

The major advantage of using Wet and Forget is the fact that it will not damage the surface you are applying it to. Common cleaners containing bleach can often damage surfaces, but Wet and Forget contains no bleach, ammonia or harmful chemicals and therefore won’t damage surface areas. It is very fast to apply, all you have to do is wet the surface and forget it!

In comparison to harsh jet washers, which can leave marks or even take chunks out of softer surfaces, the application of Wet & Forget is gentler so will not damage surfaces.

Can I use Wet and Forget to clean AstroTurf?

Yes, certainly. Be sure to have enough Wet & Forget before you start! A full pitch should need up to 4x 5 litre bottles. For AstroTurf pitches that are sand-filled or sand-dressed, make sure the pitch is liberally soaked with water.

For dealing with black fungi, leave Wet and Forget on for up to 2-4 weeks and use a sweeper to pick up dehydrated fungi off the surface. The protective nature of Wet & Forget means that the AstroTurf won’t become contaminated until up to year after initial application.

Can I store Wet & Forget in a place where the temperature drops below freezing?

We do not recommend storing Wet & Forget in an area that could freeze or have temperatures below 5 degrees. The bottle could potentially crack if it freezes.

What ambeint temperatures can I spray Wet & Forget RAPID on outside surfaces?

We recommend that the RAPID bottle is stored inside at room temperature for 24 hours before spraying during cold weather. This ensures the contents are not frozen thereby preventing the automatic mixing with water.
DO NOT spray on outside surfaces below freezing as this will prevent the absorbtion into the surface.

When should I use the fan application tip?

The ""FAN TIP"" setting is best for general application and large surfaces at ground level. If you have a large patio, driveway, tennis court or pool deck you can treat the area quickly with the wide fan spray.

When should I use the jet tip?

The ""JET TIP"" setting is best for distance and height. If are cleaning a roof or trying to reach a two story chimney you will need the ‘JET SETTING'.
(Insert image from J23 below text)

INSTRUCTIONS FOR USE: 1. Connect your garden hose to the sprayer via the black nozzle screw. 2. The pink end spray tip has two settings for how the liquid disperses, take the small pink tip, and rotate it so the black nib is inserted into the circle outing for a jet spray, or alternatively insert into the whistle shaped outing for a flat fan spray. The jet spray is for distance & height and the flat spray is for general application. 3. After choosing your desired dispensing method, turn your water supply on at the water tap. 4. Turn the bottle tap on by turning the black nozzle so the arrow points at the ‘ON’ setting. This setting mixes and dilutes the solution ready to dispense. 5. Apply the product to the surface you are cleaning, ensuring you thoroughly saturate the surface. Do not hose the surface first, the solution must be applied to a DRY surface.

PLEASE NOTE: Do not apply if rain is expected within 4-5 hours of using the product. Wet & Forget Rapid is best applied in overcast and dry conditions, to avoid evaporation. Keep away from treated surfaces until dry. Test spray a small area for colour change if spraying near dark powder coated aluminium & joinery.

This is a guide only and strength may be increased if contamination is heavy. Please ensure you wear eye protection and rubber gloves when using this product. A second application 1-2 months after the first, may also assist in treating persistent contamination.
