Hello,

I am trying to provide an estimate for materials (sand, lime putti) quantities and costs per square foot, for a future project. Do you have any recommendations for this? Currently I am using the thickness 1.25" and weight. For example 1 square foot plaster @ 1" thick weighs approximately 12 lbs. A project that is 10 square feet would weight 120lbs which is 3 bags of sand weighing 40 lbs each.

How would much putti is used per square foot?

Thanks

Mike
