How much product will I need for a roof? (For the average 3 bedroom, single storey house)
2 x 5L Wet & Forget or 2 x 2L Rapid Application (you will get the same coverage from both products)
If you have lichen on your roof you will need 3 x 5L Wet & Forget or 3 x 2L Rapid Application (needs 2 applications to penetrate the lichen)
Helpful Hints:
- Total saturation of the surface with this product is essential in order to obtain a good kill of the moss, mould, lichen, algae and fungi.
- Make sure the surface is dry in order to get the best penetration of the growth with the least amount of evaporation.
- If you have lichen, spot spray the lichen, leave for 15-20 minutes and then respray the lichen and the entire roof to ensure the lichen absorbs the Wet & Forget thoroughly.
- Then allow the surface to weather naturally and nature will take its course. The growth decomposes while the rain gently removes it from the surface over time.
- Your roof will normally take between 6-12 months to come clean.
- After intial application use as a maintenance tool. Only re-apply at the first sign of regrowth.
