How thick will adhesive be if you spread At a rate of 5 US gal per 100 sq. ft.?

1 gallon is 0.1336806 cubic feet.





0.1336806 ft^3 / 100 ft^2 = 0.0013368 ft thick = 0.016 inches


~= 1/64th of an inch per gallon, so... 5/64th of an inch -- slightly over 1/16th of an inch





.How thick will adhesive be if you spread At a rate of 5 US gal per 100 sq. ft.?
A gallon is 231 cubic inches.





5 gallons spread over 100 square feet is





5*231/(100*144) = 0.080 inches





It is common in dealing with adhesives to talk about ';mil thickness';. Mils are thousandths of an inch, so in this case, the thickness is 80 mils.





If the adhesive has a volatile component, aqueous, organic (VOC), or a combination, it will start to shrink in thickness immediately after application, so that the final thickness will be less by a factor of





(100-%voc)/100





If the adhesive contained 20% volatiles, the thickness would be reduced by a factor of





(100-20)/100 = 0.80





so the final thickness of an 80 mil coating of adhesive with 20% volatile content would be 64 mils.
