ReitenRight is installed as a top-dressing to your sand arena and takes between 1-3 hours depending on the size of your space. We typically advise our clients to divide the arena into 4-5 equal sections and distribute an even amount of ReitenRight within each section. You can use an arena tractor bucket, a manure spreader or simply hand rake ReitenRight into the top layer of sand. Once ReitenRight is evenly spread it is best to thoroughly harrow or drag your arena to blend it with your current footing. It typically takes 3-4 weeks for ReitenRight to completely settle.
