New slab about to be poured.

mx,

Epoxy doesn't really "stick" to the surface. The beauty of epoxy is that is soaks into the cured concrete, much like water does, and then hardens into a tough plastic. The surface smoothness has little to do with this.


But a smooth surface will be much easier to clean, as mentioned, and as the high spots in a rough surface will wear faster and begin to expose the concrete color under the epoxy color. If you want the natural look you could use clear marine epoxy. It's amazing how hard and durable an epoxy soaked concrete surface can be! But don't use the clear stuff if it gets sun on it.

Cool.....I guess this is like so many other things you go searching for on the internet leaves more questions than answers. I've about given up on doing the whole floor but I may do the welding equipment room, the tool room and maybe even the machine shop room floor along with the office space. My garage floor that is attached to the house has a nice sealed surface that is pretty easy to clean but it is slick as heck when it is wet especially if there is the slightest bit of oil on it. Right now it is so packed with tools and equipment that if you did slip you would never hit the floor anyway.:laughing:

I plan on turning the garage back over to the wife if I ever get my shop done then I'll probably have to take some additional insurance out on her or place some padding on the floor just in case.

I was wondering if a light broom finish would be an okay surface for an epoxy floor finish? I hate to pay a finisher to put a nice slick finish on it and have to pay someone to sand it down so that the paint can stick to it. What do you guys think?

I finished by garage floor somewhat smooth and when I epoxied it, there was some small packets of sand to mix in the paint before it gets put down. It is just enough to make it not slippery when wet and yet not rough. It works for me. Good luck.
