This guide outlines step-by-step application and loading procedures for Profile® HP-FGM and ET-FGM for hydroseeding and slope stabilization. It details equipment requirements, two-step and one-step application options, and specific mixing instructions, including loading order, water levels, agitation, and minimum mixing times to fully hydrate fibers and activate bonding additives. It provides a loading chart by tank size, recommended application rates by slope condition, and slope interruption limits. Additional notes address hose applications, rough or irregular surfaces, and residual material in tanks, along with a visual key showing proper and improper coverage and thickness at various application rates.
Key Points
- Follow manufacturer equipment instructions, use an approved hydro-spraying machine with a 50-degree fan-type nozzle, and apply from opposing directions for 100% soil coverage.
- For maximum performance, apply agronomic formulations with 50% of seed first, then apply HP-FGM or ET-FGM at 50 pounds per 125 gallons of water over freshly seeded surfaces.
- Loading charts specify the number of 50-lb bales and treated area at application rates from 2,500 to 4,500 lb/acre for tanks from 250 to 4,000 gallons.
- Application rate and slope interruption limits vary by slope condition, with recommendations for below ECB or TRM, as infill for TRM, and for slopes greater than 1H:1V.
