lockdown801 Posted April 5, 2010 Report Share Posted April 5, 2010 I just purchased 2 gallons of spectrum. I was wondering how much area will each gallon effectively cover? I am tearing out my interior of my ram mega cab so I can use this stuff top to bottom. Quote Link to comment Share on other sites More sharing options...
Reallunacy Posted April 5, 2010 Report Share Posted April 5, 2010 Their site says: Specification Weight per wet gallon = 12.5 lbs. Weight per cured gallon = 10.2 lbs Coverage: 1 gallon = 40 sq ft @ 40 mils thick (40/1000") or 1mm Suggested Thickness: Minimum = 40 mils (1mm) Reccomended thickness = 80 mils (2mm) Maximum = 120 mils (3mm) on the spectrum page. http://www.secondskinaudio.com/sound-deadener/spectrum.php#tab5 Quote Link to comment Share on other sites More sharing options...
