Getting started with the epoxy kit
I looked at the garage floor and decided it was finally time to do something about the cracks and the dusty, uneven concrete. It had been bugging me for years. I ended up buying a standard epoxy floor kit from a local paint supplier—not the top-tier professional grade, but something around 150,000 KRW that claimed to be ‘easy’ for homeowners. The guy at the shop gave me a quick rundown on using epoxy primer and then the base coat, but he talked so fast that I barely caught the part about the curing time. I figured I would just wing it on a Saturday morning.
The reality of preparation work
The biggest mistake was underestimating the prep work. The instructions mentioned cleaning the surface, but they didn’t really emphasize that the concrete needed to be bone dry and perfectly sweeped. I spent almost four hours just scrubbing and trying to get rid of oil stains near where I park my car. My back was killing me by the time I actually cracked open the cans. Using the epoxy bond was surprisingly sticky, and it got everywhere—on my shoes, the edges of the wall, and eventually a little bit on my hair. I kept thinking about those news stories I read about construction sites using steel plates and epoxy to fix structural columns, and I felt a bit silly for thinking my garage project was remotely comparable. It’s definitely not the same kind of stress, but the smell was certainly overwhelming even with the door wide open.
Struggling with the drying process
Once I started applying the mixture, the clock became my enemy. The instructions said the pot life—the time you have before it starts hardening in the bucket—was maybe 30 to 40 minutes. I felt like I was running a race. I was sweating through my shirt, trying to get an even spread across the concrete without leaving any obvious lap marks. Looking back, I definitely didn’t mix the hardener well enough in one corner, and even now, two weeks later, that specific spot feels a bit tacky when the weather gets warm. It’s annoying to look at every time I pull the car in. It wasn’t the disaster I feared, but it’s far from the smooth, professional finish I saw on the label of the paint bucket.
The lingering smell and second thoughts
For the first three days, the entire house smelled like chemicals. My family kept asking when I was going to be ‘done’ with the garage, and I didn’t really have a good answer. I used a bit of transparent silicone around the edges where the epoxy didn’t quite reach the baseboards, but it looks a bit messy. I’ve seen people talk about using special heat-reflective paints for roofs or industrial-grade urethanes for professional spaces, and I can’t help but wonder if I should have just left it alone or hired someone who actually knew how to balance the temperature and the application thickness.
Is it actually worth the effort
I’m currently standing in the garage looking at a couple of spots where the dust settled before the coating fully cured. It’s frustrating, but it’s covered now, which is better than the crumbling concrete I had before. I still have about half a gallon of the stuff left over in the basement. I’m not sure if I’ll ever use it for anything else, but I can’t quite bring myself to throw it away either. It’s sitting there on the shelf, a constant reminder that some DIY projects are just meant to be ‘good enough’ rather than perfect. I think I’m done with floor projects for a while, though.
That silicone sealant does look a little awkward around the edges, doesn’t it? I’d have probably gone with a dark grey to better hide any imperfections.
