Convenient Chart For Gallons of Polyurea required to Cover 100 ft2 of Substrate
 
 

Typically, manufacturers and suppliers of raw materials publish theoretical data for the coverage of coatings of a generic nature. Coverage is estimated using 1600 ft2/gal/mil applied. Losses are estimated with reference to wind conditions, overspray, and samples taken. The following charts are developed by actual weight measurements with controlled conditions using pure (PDA specifications) polyurea.
Data  

:

Specific Gravity of Iso = 1.12g/cm3

Specific Gravity of Resin = 1.02g/cm3

Elastomer Density = 60 lbs/ft3

Lbs/gallon of Material = 8.93

One Drum Set = 910 lbs

 

Step 1– Choose the desired coating thickness

Step 2 – Estimate the percentage lost to over-spray and handling

Step 3 – Determine the gallons of PCSI polyurea to cover 100 ft2

Chart 2 can be used to estimate the number of square feet that a drum set can cover.
 

Specific Gravity of Iso = 1.12 g/cm3

Specific Gravity of Resin = 1.02 g/cm3

Elastomer Density = 60 lbs/ft3

Lbs/gallon of material = 8.93

One Drum Set = 910 lbs

 

Step 1 – Chose the desired coating thickness

Step 2 -  Estimate the percentage lost to over-spray and handling

Step 3 -  Determine the number of square feet a drum set of PCSI polyurea will cover
