Calculate how many tubes of sealant you need to fill a joint of a given size.
Sealant Tubes
— tubes
Standard 10.1 oz tubes.Usage Tip
Use a backer rod in deep joints so the sealant bonds to just two sides and can flex without tearing.
THE MATH
joint volume (cu in) = linear feet × 12 × width × depth
fluid ounces = cu in × 0.554
tubes = round up( fluid ounces ÷ 10.1 )
fluid ounces = cu in × 0.554
tubes = round up( fluid ounces ÷ 10.1 )
Sealant fills a joint of a given width and depth. The volume is the joint cross-section times the length, converted to fluid ounces and then to standard tubes.
Enter the joint length in feet and its width and depth in inches.
A standard tube holds about 10.1 fluid ounces.
