Roof Coating Dry Film Thickness
Dry Film Thickness (DFT) is the thickness of a roof coating after it is dry or fully cured. Use the solids by volume property to quickly compute application DFT using the following formula:
dft = 16 x (% solids by volume)
Maintaining Coverage Rates
Measuring Wet Film Thickness
A toothed wet film gauge is useful for verifying application thickness while the coating is still wet. Place the gauge at 90 degrees to the coated surface. Read the largest tooth that is wet.
