1. All paints include instructions on the container which also specify typical coverage. Typical elastomeric paints go on think (~15 mils), and will only cover 120 sf/gal. Most also require 2 coats for a waterproof seal, which will require twice as much paint (bringing coverage down to just 60 sf/gal for 2 coats).

2. For fresh concrete, never been painted before, it is 120 square feet per gallon for the first coat. A second coat would be about 150 square feet per gallon.
