25kg bags of MAG Chloride for easy handling. Mag flakes applied in recommended rates to your indoor footing acts as a humectant to attract and retain moisture from the air within the particles of your footing. You need only to groom the footing on a regular basis as to keep your footing performing well and dust free for rider and horse.

There are an infinite number of blends of arena materials that are used by equestrians in indoor arenas. The common problem in all footings is pulverized by the hoof action of constant riding and pounding. There is no limit to the formulas of footings for each individual facility. The common denominator is that over time they all break down. And dust becomes a problem. Even rubber products will break down and eventually become airborne dust particles.

Applying MAG to an indoor ring is all art and little science. Recognizing that footings are very individual, the objective in all footings is to maintain a consistent level of loose material to provide the desired amount of give.

The objective of proper dust control using MAG is to 'sneak up' on the correct amount and NOT OVER APPLY. When applying the product, always apply conservative amounts over a period of weeks, allowing ring use to mix the product into the footing to achieve the desired level of dust control.

The worst thing that you can do when using MAG is to water your ring. ONCE YOU COMMIT TO USING MAG, it is very important that all watering for dust control is halted. The reason is simple: You are applying a dust control agent at the surface, and gravity and hoof action will help it to penetrate the footing, coat all the particles of footing and hold them down on the arena floor where you want them. By watering after you have applied MAG, you are rinsing the product off the top and into the subsurface.

The amount needed varies depending upon your ring, but generally speaking, we find that it takes 2 to 4 pallets of MAG to achieve complete dust stabilization. Once the ring is completely stabilized you NEVER need to water again. In fact, watering the ring after it is stabilized with MAG is counterproductive and only rinses the dust control agent into the base where it does you no good. We recommend a maintenance dose of approximately one pallet per year to touch up around doorways where traffic and rain may remove the treated footing, and also to combat dust arising from other materials that are added to the indoor arena such as contaminants from boots, hooves and manure.

MAG will last forever, or until you wash it away with water or add new footing.

This is the most important part of any successful program: Maintenance, you change the oil in the tractor, the car, and grease and maintain all the other tools of horse management so why wouldn't you also maintain your riding surface?

We recommend that you regularly groom your riding surface with either a tine harrow or other drag-type device which will pull the footing up from the base and turn it over. Even an old piece of chain link fence dragged behind a machine will smooth out and level the riding surface. More often than not, the highest levels of dust are seen when grooming an untreated indoor ring. The best grooming devices are ones which have 'teeth' that will dig into the footing and fluff it and turn it over while smoothing it out at the same time.

So regular grooming is the No.1 way to properly maintain your indoor ring once it is treated for dust. Next, a small maintenance dose of MAG for use around around the doorways and problem areas is recommended. The average 30m x 60m indoor ring will take three pallets of MAG to fully stabilize and then one pallet of MAG per year to maintain. Compare these costs to the costs of a sprinkler system and frozen footing in the winter.

The is a side benefit to MAG stabilization that has not been mentioned: freeze proofing your ring. You will never again be forced to shut down in winter because the water saturated footing in your indoor froze up, and you could not ride in it because it is like a frozen moonscape. MAG will keep the same consistency in your footing throughout the year including those sub-zero days when you were not able to ride because the indoor was hard as a stone.

The term 'this is not rocket science' comes to mind first. Think of applying MAG to your indoor as though you are fertilizing your lawn. You want to get even, thorough coverage. To do this we recommend the use of a broadcast spreader, or rotary spreader. Using a rotary spreader, fill the spreader to capacity and begin at the far end of the arena away from the 'stockpile' of MAG.

Open the spreader up to full capacity (wide open) and then begin by making a checkerboard pattern going north and south in your arena and then east and west over the same area in a checkerboard pattern. When MAG is properly applied, it will look like it just snowed a light snow in the indoor. You will immediately see MAG start to pull in moisture and dissolve into the footing. This is what its supposed to do and what will effect dust control.

This is only the first application but because all footings are different, and dust levels vary widely, this is a starting point that is more than half way to complete control for the average indoor. Next we suggest that you 'sneak up' on the final amount needed for complete dust control in your indoor. Continue to add MAG, but do so at much lower levels until you have achieved complete dust control.

It is very important to not over-treat. Over-treating will result in a fully saturated, muddy , slippery, wet footing, that will compact and work against you. If you do make a mistake, and one week after treating find that you have over treated your indoor, then use a sprinkler to rinse away some of the product and drive it into the subsurface. This must be done with great care to avoid over rinsing and losing the job that you just worked so hard to do. With so many different types of footing, it is impossible to speculate about how much MAG it will take to stabilize or how much water it will take to "remove" some of the MAG that was over applied. As stated up front, this is not rocket science, and as a stable owner and barn manager, you know better than anyone that common sense is the best guide.

While the first day after the first treatment you may think that you are all set, we find that a week or two later dust may begin to break through a little as the fines underneath the surface begin to work up and need to be treated. Typically a small maintenance dose of MAG is required from time to time to suppress new fines as they develop in normal ring use and around doorways and entries where rain may wash away some of the treatment, or where dirt and other sources of dust are dragged in to the arena.


  • Prepare the arena to be treated by grooming and levelling
  • Use a checkerboard pattern to apply product evenly
  • DO NOT WATER - EVER! (It is ok to "spritz" the ring once)
  • Thoroughly rinse down all equipment after each application.
