M-Binder Tackifier-Soil Stabilizer

Yes. For dry application, load M-Binder into a broadcast or shoulder-bag spreader and spread at 1.5–3.25 lbs per 1,000 sq ft over seeded areas. The fine powder may require occasional tapping of the hopper to keep it flowing consistently. After spreading, water the area thoroughly to activate the tackifier. You can also mix it with water in a bucket to create a slurry for small areas, or use a hydroseeder tank for larger projects.

No—rain actually activates it. M-Binder is designed to swell into a gel when wet, bonding seed and soil together. Users report it holding seed in place through multiple heavy rainstorms. You can even apply it during rain, since moisture immediately triggers its binding properties. Once dry, it forms a firm membrane that reactivates with each subsequent wetting. For steep slopes or extreme rainfall, increase the application rate to 3–4 lbs per 1,000 sq ft for extra holding power.

Yes. M-Binder is 100% organic, non-toxic, and biodegradable. It is derived from the seed coating of Plantago insularis—the same plant family used to produce psyllium fiber in human dietary supplements. It contains no synthetic chemicals, petroleum products, or polymers. It is safe to use near ponds, streams, wells, and aquatic habitats. Comparable psyllium-based tackifiers meet the Lake Tahoe BMP requirements for non-toxicity to plant and animal life. Keep pets off treated areas until the tackifier is watered in and dried (about 12–18 hours) simply to avoid tracking powder.

Coverage depends on application rate and slope. At the standard rate for flat to gentle slopes (1.5–2 lbs per 1,000 sq ft), one pound covers approximately 500–667 sq ft. At heavier rates for steep slopes and erosion control (3–4 lbs per 1,000 sq ft), one pound covers about 250–333 sq ft. Check the product weight on your bag and multiply accordingly. For hydroseeding projects, plan on 60–160 lbs per acre depending on slope severity.

Absolutely. The dry application method is the simplest approach for homeowners and small projects. Broadcast your seed first, then spread M-Binder over the top with a broadcast or shoulder-bag spreader. Water thoroughly to activate. You can also mix it with water in a five-gallon bucket to create a slurry and apply with a watering can or pump sprayer. The hydroseeder method is best for large-scale projects and steep slopes, but it is completely optional for residential use.

Yes—over-application can create too thick a barrier over the seed, inhibiting germination and emergence. This is documented by Caltrans and other agencies that work with tackifiers. Stick to the recommended rates: 1.5–3.25 lbs per 1,000 sq ft for most applications, up to 4 lbs per 1,000 sq ft for steep slopes and dust control. When in doubt, start at the lower rate and increase only if washout is a problem. The reactivating nature of M-Binder means one application at the right rate provides ongoing protection—more product does not always mean better results.
