How to Use This Calculator

Enter Floor Area (sq ft) and the Layer Thickness (inches) for each coat.
Set the Number of Coats (typically 2-4 for a finish floor).
Input Oil Coverage (sq ft/gal) for the linseed oil hardening finish.
Review Total Material (cu ft), Clay Soil (cu yd), and Sand (cu yd) needed.
Calculate oil quantity from coverage to order the correct amount of boiled linseed oil.

How the result changes with Floor area (sq ft)

Total material (cu ft): Total volume of earthen floor material for all coats.
Clay soil (cu yd): Volume of clay soil (~40% of mix).
Sand (cu yd): Volume of sand (~40% of mix).
Chopped straw (lb): Weight of chopped straw fiber reinforcement.
Linseed oil (gal): Gallons of linseed oil for floor sealing.

Identify Input Parameters
4 parameters
Floor area (sq ft) = 200, Layer thickness (in) = 4, Number of coats = 2, Oil coverage (sq ft/gal) = 200 = 4 input(s) provided
Calculate Total material
Total material = volPerCoat * numCoats
133.33 = 133.33
Calculate Clay soil
Clay soil = round((totalVol * 0.40) / 27 * 100) / 100
1.98 = 1.98
Calculate Sand
Sand = round((totalVol * 0.40) / 27 * 100) / 100
1.98 = 1.98
