"thick paint" is very vague. what is thick to YOU may not be thick to me. It depends on the type of paint, ( latex, alkyd, enamel etc,) -it's actual viscosity, how you apply it ( brush, roller, spray etc ) and finally the smoothness of the surface. 5 gal could cover anything from 500 to 2,000 square feet. - An average household latex applied to a smooth surface with a roller will cover about 300 sq.ft. per gallon.
