5L Wet and Forget

Wet & Forget is the safest, most effective way of removing moss and mould from ANY exterior surface. When applied, it immediately attacks that unsightly moss, mould and grime. Then Mother Nature takes over. The weathering process gently takes the decomposing material away bit by bit without scouring the surface it has infested.

How to apply Wet & Forget

  • Sweep all leaves, dirt and other debris off the surface before application to allow for maximum penetration of the active ingredients.
  • Dilute one part Wet & Forget to five parts water (1:5) in a garden or backpack sprayer.
  • Spray the affected area to the point of saturation. Do not hose off.
  • Apply during overcast, dry conditions to avoid accelerated evaporation.
  • Do not apply if rain is expected in the next 12 hours.
  • Lichen requires a second application within 15 minutes of the first.
  • Keep children and pets off the treated surface until dry (normally 1-2 hours).
  • If badly contaminated, apply a second application one month after the first.
  • When to expect results with Wet & Forget
  • Algae will disappear within days.
  • Moss will turn brown within a few days and other light growth will decompose within a few weeks.
  • Black mould will noticeably improve within 4-6 months, however if the area is heavily contaminated it will take 6-12 months.
  • Lichen requires two applications within 15 minutes of each other and will take 8-12 months to decompose.

Note: It is normal for some treated surfaces to turn an orange/brown colour after application. This discoloration indicates a good result, however it is not permanent and will soon disappear.
