Yes, another Rust Bullet thread 
I have a two-car garage with one stall being extra deep which is where my workbench and tools are. Since I can't move all of my stuff out of my garage and keep it out there for multiple days, I decided I'll do it in sections. I decided to do this smaller back section first (170 sq/ft) to work on my technique and test the product.
Here I'm getting ready to grind with a 7" angle grinder with shroud, Diamabrush, and 14 gal Ridgid shop vac with drywall bags.
Part way done, having to stop to clean the filter multiple times. Turns out the cheaper bags from Amazon are in fact cheaper as both of them ended up blowing out before anywhere near full, meaning the filter got clogged.
Finished grinding and patched the floor with Rustoleum Epoxy Floor Patch
No pictures of it after I ground the patches, but the Diamabrush made quick work of it.
First coat down, it really soaked in
Second coat
Third and final coat after a few hours of curing
Overall I'm pretty happy so far. The roller marks ****, but one of the main reasons I went with Rust Bullet and applied it myself is that my garage already has a ton of flaws, so I don't need a show-quality floor. I want a durable floor that can be touched up if needed and doesn't break the bank.
I finished applying this just last night (about 12 hours ago), and I can already walk on it. Despite 50% humidity at 60 degrees, the time it took for each coat to be tack free was only about 3 hours (I applied 3 coats in roughly 10 hours). I'll let it set up over a few days before moving stuff back onto it.
What I'm going to do with the rest of my garage floor is another story. It would be a lot to grind by hand, and there is a considerable amount of spalling which needs some type of skim coat (using the epoxy patch would take forever). More on that on post #8
Lessons Learned
1. Roller Marks
As you can probably see in the pictures, there are some pretty bad roller marks. I might have used a wrong roller cover, as I used a 3/8" nap Purdy Professional cover. I may not have mixed the product well enough, despite mixing the 1 gallon for 3 minutes, and mixing in between coats. No matter how long you mix you can't get it to be homogeneous due the the aluminum content.
However, I think the biggest thing is the technique. I'm good at back rolling, and maybe this is due to the roller cover, but no matter what, rolling forward created a different texture than rolling backward, and a slight difference in texture is very obvious with this stuff. I realized on the final section of the 3rd coat that if I held the roller extension almost parallel with the floor it provides the most uniformity as there's no downward pressure when pushing forward. It didn't help that my last roller cover seemed out of round too (I used a new cover for each coat).
Also, this may have to do with the product starting to set up between coats. When I poured out the product initially (around noon), it was like water. But each time I poured more it was gradually getting thicker.
2. Coverage
I used 1 gallon for 3 coats on this 170 sq/ft section. I made sure not to apply it too thick, but then noticed that it had not seeped into any little holes in the concrete that I didn't patch. On the 3rd coat I went back and filled the holes using a little brush before rolling on the 3rd coat, but now you can see those spots I touched up. Oh well, better to have a coating there so that nothing can seep into the concrete.
3. Solvent Fumes
The fumes are brutal. I wore a respirator when applying, but unfortunately had no ventilation in the garage because any bit of draft would have caused stuff to blow onto the paint. The smell was so strong that it seeped into my house, and I woke up this morning and it was really strong. It was below 50 degrees this morning, but I had to open up the windows.
4. Cleanup
Buy the solvent when you order from Garage Flooring LLC. I didn't, and I didn't wear gloves during the first coat. You can remove this stuff from your hands just fine with Xylene before it dries, but once it does it's on there and it remains sticky for some time.
