Engineered Fiber Matrix® (EFM) is mixed at 27 kilograms per 379 liters of water and applied with approved hydro-spraying machines using a 50-degree fan-type nozzle for 100% soil surface coverage. Directions outline a two-step process combining fertilizer and seed with EFM, detailed tank loading and agitation steps, and spraying in opposing directions. Application rates vary by slope from 3,360 to 4,480 kg/ha, and EFM is not recommended for slopes greater than 1H:1V. Best results and more rapid curing are achieved at temperatures exceeding 60°F (15°C), with equipment flushing required to reduce health and equipment hazards.
Key Points
- Engineered Fiber Matrix is mixed at 27 kilograms per 379 liters of water in a low water-to-product ratio; do not add additional tackifiers or polymers to this pre-mixed formulation.
- For maximum performance, apply in a two-step process, with fertilizer and part of the seed first, followed by EFM at 27 kilograms per 379 liters (22.7 kg bale/316 liters) over freshly seeded surfaces.
- Application rates are 3,360, 3,920 or 4,480 kg/ha based on slope condition, with slope interruption limits of 15 m on 3H:1V slopes; EFM is not recommended for slopes greater than 1H:1V.
- Best results and more rapid curing are achieved above 60°F (15°C), and hydraulic equipment should be flushed after each application as residual compounds may form and can be hazardous to human health and equipment.
