FAQs

What is the dilution rate and coverage area?

Wet & Forget is concentrated therefore dilute Wet & Forget 1 part to 5 parts water. Every 5 litre pack yields 30 litres of product to spray. With this you will get coverage of between 100 - 300 sq m depending on the porosity of the surface ie painted surfaces will use less but porous surfaces readily absorb the product and therefore coverage could be in the range of 100-150sq m. We recommend using a garden sprayer.

Can I change the specified ratios given in the instructions?

Yes. For instance if the contamination is extreme, increase the strength for a quicker reaction. However, if you have cleaned the surface previously with Wet & Forget and you want to give it just a maintenance spray, you can decrease the strength if the contamination is light. The cleaning process will still be as effective.

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, Astroturf, bowling greens, bricks and paving, canvas tents, caravan awnings, conservatories, fibreglass boats, greenhouses, golf greens, limestone, sandstone, marble, outdoor furniture, outdoor pots, outdoor painted surfaces, pool surrounds, shade sails, slate, tennis courts, yacht sails.

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

Ideally, remove any excess debris. It is not necessary to wash the surface prior to application - 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 has become clean you can paint or stain over Wet & Forget. It is great for extending the life of the surface as it not only removes moss, mould, lichen and algae, but also the surfactant action helps remove dirt and other residue. Spraying your house annually with Wet & Forget will extend the life of your paint.

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, 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. Plus it will not damage your garden sprayer as the product is not corrosive.

Will it affect my pets?

Not under normal circumstances. However, keep 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 will it last in the container?

Forever and light does not damage the efficiency of the product. But always keep the cap done up tightly and the container out of reach of children.

How long will it take 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 orangey brown when the Wet & Forget 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.

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.

Will Wet & Forget get moss out of lawns?

Sure will! Moss on lawns 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 5Litre 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. Broadcast area with garden lime to change the ph levels. If it's early spring or autumn, overseed & fertilise.

How do I prepare Wet and Forget for application?
