When to apply Simply Gone

It can be applied all year round to treat problem areas but for the best results:

The surface should be dry before treating
Do not spray if rain is expected within 24hrs of application (The longer Simply Gone dries on the surface - the better the results)
Do not spray if the temperature is below 8ºc
Do not spray during a heat wave (To avoid rapid evaporation, ideally spray early morning or late afternoon)

RESULTS

These will depend on many contributing factors: correct dilution and application, type of surface, extent of growth and the variety of algae, moss, fungi, mould, lichen, plus weather conditions and likelihood of precipitation.

As a rough guide:

Algae, fungi & moulds	Results should be seen within 2 - 4 days after application. NB In some cases, once the algae is killed, it turns black - this may take up to several months for the natural elements to remove.
Moss	Results should be seen within 5 -21 days after application. NB Some mosses are very compact & difficult to penetrate the stem structure, therefore consider brushing off any heavy growth before treatment.

Once the plants are dead the 'weather' will gradually erode them away and the surface should start to clean and brighten for the next 4 months. If you want a more instant clean eg moss on tennis courts, you can brush the surface 14-21 days after application once the plants are dead and roots have lost their adhesion.

NB Lichen is a very tough plant structure and once sprayed can take up to 1 year for the weather to remove naturally.

THE PREVENTATIVE PROGRAM

At least once a year spray your required 'clean' area with a 1:20 dilution of Simply Gone. This will kill any spores on the surface and will prevent new growth from six to 12 months depending on weather and wind conditions.

NB when you see an infestation of algae, moss or fungi appearing spray immediately to prevent it from deteriorating the surface or spreading to other areas.
