The Soiltac worked great. It was perfect for the project and let me sleep like a baby unless a hurricane was forecast. I just mixed it in a two gallon pump or back pack sprayer and sprayed it liberally (about 2 gallons of 40:1 mix per 9 square yards) on where we'd seeded. A 40:1 mix equals 3.2 ounces of Soiltac per gallon of water. Any sprayer will do, but be sure to rinse it well after use.
While not advertised as a tackifier it is listed in their rate table:
http://www.soiltac.com/application-rates.aspxI forget how I stumbled upon them. I wanted an organic guar gum tackifier, but couldn't find one readily available. While not organic, Soiltac seemed to be safe and environmentally friendly.
It was very hard to find information on tackfiers and when I did their ordering system would be terrible and they would only deal in huge quantities.
Soiltac has an easy online ordering system and they will sell in 1 quart or 5 gallon "sample" quantities. They were very helpful and would promptly answer any question.
It is pretty versatile. I plan to always have some around for holding problem drainage areas in place.
I also used Greenview Grass Seed Accelerator paper mulch which also seemed to help hold the seeding in place. I threw the mulch on at least an hour after spraying the area with Soiltac because I didn't want the mulch soaking it all up.
