Full broadcasat disater

[JD2773]

I did a full broadcast of 6mm flakes on a 400 sq ft two car garage that is only 2 years old. I made sure to prep the floor with multiple cleanings with muriatic acid. After waiting 3 days for the floor to dry and 24 hrs after the first coating of exopy was applied, my helper applied the second coat while I applied the flakes with spiked sandals. I applied 80lbs of flakes and made sure that no visible epoxy was "shining" though. I waited 24hrs until I picked up all the loose flakes. After I used the floor scrapper I could see the disater of a project that I had. The pictures below is what it looks like after the cleaning. The floor was preped well and the outside temp was 75. The only thing I can think that might have caused this is that my helper applied the expoy to thin in areas.

My thoughts to fix this was to apply a single topcoat, spread with flat blade squeegee, back roll the topcoat and then apply more flakes to the bare spots. Then apply a second topcoat. I'm not sure if that is sound or not. Originally I was going to apply Rust-Oleum EpoxyShield 2-part Clear High-gloss since I got 2 boxes very cheap. But, not sure if that is the proper product to use in this situation. My thoughts is to get a Polyaspartic a Polyurea instead. But, not sure how much would be needed in this kind of application.

What epoxy product did you use?

I used ArmorUltra Epoxy

I used ArmorUltra Epoxy

ArmorUltra is a 100% solids epoxy and is plenty thick enough for a full flake broadcast when applied at the proper coverage rates. Your suspicion of the helper applying too thin in areas would be accurate. There are a couple of different methods for fixing the problems. Applying a clear coat, applying more flakes, and then more clear is one way. Another is to apply another color coat and broadcast again. However, I would recommend contacting ArmorPoxy and discussing it with them first.

 

[Garage Flooring]

One thing that helps a lot on a full broadcast is to make sure you sand between the flake and the clear. Broadcast to complete rejection, vac, sand, vac then clear. It is hard to tell from the photos but a couple of layers of clear may make this floor look way better.

 

[Armorpoxy]

We agree, clear and re-broadcasting can help to fix this. Did you prime this floor first as priming makes the epoxy sit higher on the floor and not absorb in so that they hold the flecks much better?
