How to Apply Moss & Mould Control

How It Works Best

Moss & Mould Control works best by simply spraying onto the surfaces to be cleaned and letting the weather do the work. If surfaces are not fully exposed to rain or are vertical, you may need to lend a hand by washing off remaining grime with a garden hose.

For best results, apply when it is dry and overcast. This avoids the solution evaporating before it can get to work. Do not apply if rain is expected within 4 to 5 hours of application.

Directions for Use

  1. Shake well before use.
  2. Mix 1 part concentrate to 10 parts water (a 5L bottle makes 55 litres of solution).
  3. Spray on liberally with a garden sprayer or watering can to all outside surfaces, making sure the area being treated is thoroughly saturated.
  4. For heavily soiled areas, leave for at least one week and clean with a brush as necessary. Otherwise, leave for the weather to finish its work.

Working Time

Moss & Mould Control is not designed to be an instant cleaner. Its gentle formulation is designed to clean outside surfaces over 6 to 12 months for the dirtiest surfaces. For best results, it is important the mixing instructions are followed carefully.

Timber Decking

Pinus Radiata or Kwila decking surfaces that are exceptionally dirty usually exhibit a black fungus. Once treated with Moss & Mould Control, you may need to remove the dead matter with a brush. To prevent the fungus reoccurring, treat your decking on a regular basis.
