Application & Tips

Application: Apply Wet & Forget Outdoor Ready-To-Use to a DRY outdoor surface until thoroughly saturated. Wet & Forget is best applied in cool, dry conditions to avoid evaporation. Do not use if rain is in the forecast within 4-5 hours. Avoid application during the warmest part of the day or on unusually hot days, to avoid evaporation which can dimension results. Temperatures need to be above 32 degrees during application and for approximately 5 hours after.

You'll never have to wait for results after your first initial cleaning; you'll move to an annual maintenance application to keep those surfaces mold-free.

Reaction Time: Once treated with Wet & Forget, green growths such as algae will clean up within a few days or weeks in most cases. Black stains caused by mold and mildew can take a month, sometimes several months. Worse-case scenario, heavy black stains that have built-up for many years can take six months - 1 year to come clean. Be Patient. Good Things Take Time.

Treating Moss: To get rid of moss, thoroughly saturate the moss making sure the Wet & Forget Outdoor soaks through and comes in contact with the surface the moss has attached itself to. Over the next few days or weeks, you'll notice the moss turning brown, curling up and detaching from the surface. The wind and rain will help wash away any remaining moss.

Treating Lichen: Lichen is a complex combination of fungus and algae that have learned to live together, forming a unique type of growth. Lichen can cause pitting on outdoor surfaces. The symbiotic relationship between the fungus and algae makes lichen very hardy and difficult to get rid of. But don't worry--even this robust growth is no match for Wet & Forget Outdoor. Use a garden sprayer to thoroughly saturate the lichen with a solution of 1 part Wet & Forget Outdoor and 5 parts water. Wait 15 minutes, and spray a second time. The outer shell will soften during this time so Wet & Forget can penetrate the lichen's inner layer. It is best to spray lichen on a day that is not too sunny, to prevent rapid evaporation and to allow Wet & Forget more time to work.
