The Concrete Network on Surface Preparation

For Concrete polymer-modified overlays:
Contractors and manufacturers are split between roughening the concrete by mechanical profiling or acid etching. Large or difficult surfaces will usually be mechanically profiled.
Acid etching can provide adequate surface preparation for horizontal installations of coatings, and toppings in areas that are well ventilated and require a sparkand/ or dust free environment. But they will not remove petroleum-based products or animal vegetable oils from the concrete.
After acid etching is done- the surface must be neutralized. Bonding problems can occur if acidic residue remains on the concrete.
For Floor Coatings in Industrial or Commercial Applications:
"Mechanical profiling is the method of choice." Thomas Kline of Structural Preservation
William Perenchio of Wiss, Janney, Elstner Associates, Inc. notes that "acid etching should only be done when no alternative means of preparation is possible."
