Can you put epoxy over self leveling concrete?
Another huge benefit to using epoxy for a self-leveling overlay is the fact that epoxy itself is a sealer. In theory, assuming your floor doesn’t require more than one coat of epoxy self-levelling overlay, you could do one coat and your floor would be level, sealed and the colour you want.
How do you prepare a concrete floor for epoxy?
Prepping Your Concrete Floor
Before you apply any coating, you need a clean, dry floor without debris, moisture, cracks or holes. Give the area a thorough sweep. Clean up any grease stains with a degreaser and a stiff brush. You don’t need to remove all of the discoloration, just the greasy residue.

How do you even out a concrete floor?
The easiest way is to use a self-leveling compound, also called liquid floor underlayment or floor resurfacer, within sections of level-cut rails. The material flows out like thick syrup, then hardens into a smooth, perfectly level surface, sometimes in less than an hour.
How do you level uneven concrete?
Grind any high and inconsistent spots into the same level by moving the grinding plate back-forth and sideways. Mix your leveling compound into a thin and consistent paste. The paste seals the floor cracks. Spread the leveling primer on the surface using a soft bristle push broom and ensure the layer is smooth.
