- Brush off any dirt or loose debris from the surface
- Lightly dampen area with water
- Apply NEAT using a watering can or sprayer (do NOT dilute)
- Work in by brush or stiff broom
- Make sure that surface area doesn't dry out
- Leave on surface for 1-2 hours before rinsing off
- Rinse area with water or use pressure washer if available
It is important the surface remains damp during application, as the product becomes inactive once dry. Most ingrained organic matter and grime will be removed after one application, but sometimes a second application may be required to remove all black and white spot algae. If a second application is required, leave to dwell on the surface for a longer period (2-3 hours) before rinsing or pressure washing off.
