What’s happening in this video…A urethane top coat [Garon Hi-Gloss] being applied to an aircraft hangar floor at 3 mils thick with a 3/8″ hair nap roller.
Following the top coat application on this aircraft hangar floor is a light broadcast of aggregate [Garon Grit 60] at the rate of 1 lb. per 100 sq. ft.
To ensure the aggregate embeds in the top coat, the floor coating is rolled again with a 3/8″ hair nap roller. This provide the ultimate performance flooring. Typical hangar floor painting without this step will never last and the potential for slip and falls will definitely be on the high side.
Broadcasting an aggregate into an epoxy floor coating is an excellent way to achieve traction enhancement while maintaining the aesthetic look of the concrete floor coating.
Frequently asked questions about adding traction enhancement to garage floor coatings for an aircraft hangar facility…
Why is aggregate broadcast into some floor coating systems?
Well, aggregate is broadcast into concrete floor coatings for many reasons. One is to provide safe footing to those who will walk on the surface. Another is to comply with ADA and OSHA. ADA demands a 0.6 coefficient of friction on the floor surface.
The regulations are the same for both private and public facilities. There are a lot of lubricants and oils in this environment and these products can produce slip hazards on the flooring surface.
The selection of the aggregate size, meaning mesh size, is pivotal. It’s vital to select the correct aggregate to broadcast. Typically a 46 to a 36 aluminum oxide aggregate broadcast into a urethane top coat will give an adequate amount of traction.
Keeping people on their feet and giving them the confidence to perform their work routines by eliminating most slip and fall accidents helps workers focus on their responsibilities without an ever present worry of slipping and falling.
The selection of an appropriate aggregate for those areas where needed, especially where the jet aircraft is being maintained by airmen or on the private side by the technician, is usually where that aggregate is going to be broadcast into the coating.
In other dry storage areas, there is not going to be any aggregate broadcast because extreme conditions are not present as described above.
Does broadcasting an aggregate into concrete epoxy coatings have anything to do with durability?
Broadcasting will definitely increase the durability of airplane hangar flooring. When broadcasting, depending on the type of broadcast chosen, there is an option to apply a pound per 100 square foot that’s considered a light broadcast. That’s just really to keep people on their feet.
But of course when broadcasting to excess, or as it is called “beaching” the aggregate, a double broadcast flooring system will provide a much tighter matrix providing more longevity and traction for the floor
So there are two types of sand use in an aircraft hangar flooring system. One is ADA compliance and the other is a component that’s essential to what is called a broadcast system. The latter would be the more adequate for longevity.
