Floyd County, Iowa | I used to have our road sprayed with lignin (tree sap base). It was great until it rained, then washed away. For the last 7 or 8 years, I've used magnesium chloride, and really like it for dust.
Upside is that it will stay much longer. We have it done twice a year, and the guy charges about $430. This is for 2 applications, and we have him do a 400 foot section each time.
Downside is that when we get snow, and it is just below freezing, the mag chlor will keep the snow melted, so I know what it can do to the underside of our vehicles. | |
