FibraTac Powder Tackifier is a 100% natural, non-toxic tackifier that is sold in convenient 20 lb pails. This tackifier not only helps as a lubricant to improve spraying of the mulch slurry, but also has remarkable adhesive properties. This tackifier takes less time than other powdered tackifiers to mix into the slurry, and with less lumping. FibraTac powder prevents soil and sand erosion and fugitive dust. It binds seed, fertilizer and mulch together with the soil to control erosion and enhance seed germination. Used for normal to moderate slope conditions.
