Rapid Mould Algae Remover 2L Hose End

Rapid Application moss, mould, lichen and algae remover is the new and improved ready-to-use hose end version of the original Wet & Forget outdoor concentrate. Rapid Application features a patented nozzle design that allows the product to reach up to 8 metres (2 storeys). Rapid Application works exactly the same as the original Wet and Forget 5L concentrate, and covers the same minimum area.

AUD $99

Rapid Application works in exactly the same way as the original Wet & Forget concentrate, however it has been made easier to use and faster to apply! Rapid Application has a unique combination of biodegradable selective fungicides to target moss, mould, lichen, algae, and general biological growth. Like the original Wet & Forget concentrate, Rapid Application kills the spores. The weathering process gently removes the decomposing growth over time without damaging the surface it has infested.
Works exactly the same way as the original Wet & Forget 5L concentrate.

How to apply Rapid Application

  • Sweep all leaves, dirt and other debris off the surface before application to allow maximum penetration of the active ingredients.
  • Attach to a standard garden hose.
  • Rapid Application is best applied in overcast, dry conditions to avoid accelerated evaporation.
  • Do not apply if rain is expected within the next 12 hours.
  • Spray the affected area to the point of saturation. Do not hose off.
  • Keep children and pets off the treated surface until dry (normally 1-2 hours).
  • Lichen requires a second application within 15 minutes of the first.
  • If badly contaminated apply a second application one month after the first.

When to expect results with Rapid Application

  • 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.
