Wet & Forget

Yes. 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 just as effective.

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.

Wet & Forget has unlimited shelf life. Always keep the cap done up tightly and the container out of reach of children.

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 discolouration 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.

Dilute Wet & Forget 1:5 (1 part Wet & Forget to 5 parts water). Every 5L pack makes 30L of product to spray. With this, you will get coverage of between 100-300 sq metres depending on the porosity of the surface and the level of contamination, i.e. painted surfaces will use less product but porous surfaces readily absorb the product and therefore coverage could be in the range of 100-150sq metres.

On a cool, dry windless day and when no rain is expected for 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 Wet & Forget for an extended period.

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 immediately wash off the product with fresh water as a precaution.

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.

Most definitely! However 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 help remove the dead growth. The good news is that you should only have to do this once and then the maintenance becomes so easy.

Sure will! 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 Wet & Forget 1:7 (1 part Wet & Forget to 7 parts water) 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.

The average 3 bedroom tile roof is approx 150 sq metres, 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 5 litre 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 5 litre packs depending on the total area covered with lichen. For best results mix the Wet & Forget and spot spray the lichen, leave for 15-20 minutes (while it is still damp) and then respray the lichen and the entire roof to ensure the lichen absorbs the Wet & Forget thoroughly. The first application is to dissolve the waxy surface and 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.
