USE Concrete Floor Grinder to do the prep work
The outcome of the epoxy is determined by the floor prep, a poor prep may even cause a decent epoxy to fail. When we talk about the floor surface preparation, someone recommends to use water and acid to do the prep work, but this is never a good idea. A concrete floor grinder with a good dust shroud will be ideal to do prep work. Also if you choose the stand-up walk behind concrete floor grinder, it will save your back and hours of hard labor. As for the grinding wheels or grinding pad, 7” grinding cup wheels with 12 segments will be good if you use hand-held angle grinder, if you use the stand-up walk behind concrete floor grinder, metal bond diamonds and 10” grinding discs will be ok. Different hardness floor require different diamond grit level, but 30# grit is pretty typical for this type of work.
Clean Up the Moisture in the concrete slab
Before doing epoxy work, pls check whether there is moisture in the concrete slab, 100% solids epoxy doesn’t allow the concrete to release moisture, because the moisture can cause the epoxy to bubble and fail.
So, if the weather in your area is humid or rainy, pls put a intact vapor barrier underneath the concrete slab
Urethane top-coat after the epoxy
I usually apply a urethane top-coat after the epoxy. This is to add scratch, stain, and chemical resistance. It won’t add slip resistance unless you add a non-skid additive.
