Base Coat: one gallon covers approx. 50 sq. ft.
Finish Coat: one gallon covers approx. 50 sq. ft.

So 0.378 pounds per square foot of paint-like stuff is better than 41 PSF of 10" cinder block? WOW!

BTW: the problem with "snake oil" (a popular cure-all) was that it didn't really have any snake oil in it.

Maybe that's why it worked sometimes, somehow...
