Troubleshooting

Moss not browning after 24 hours

Ensure the product was applied thoroughly and evenly. Reapply if necessary, ensuring coverage of all affected areas. Check weather conditions; heavy rain immediately after application can reduce effectiveness.

Product seems to be running off the surface

Apply the product more sparingly. The maximum recommended application rate is 100ml per m². Use a fine mist setting on your sprayer to ensure even coverage without excessive pooling.

Accidental application on plants

Immediately rinse the affected plants with plenty of water. While designed for hard surfaces, contact with foliage can cause damage.
