Floor prep bag estimator

Floor Leveling Compound Calculator

Estimate self-leveling compound or floor patch bags from floor area, average depth, waste, bag yield, and bag cost. It connects flooring, tile, garage floor tile, and floor mud takeoffs before the finished material goes down.

Floor prep depends on product and substrate

This calculator estimates bag counts only. Primer, lath, substrate strength, moisture, temperature, minimum and maximum depth, damming, expansion joints, and manufacturer instructions control the real pour.

Floor leveling compound formula

Leveler ft³ = floor area × average depth in ÷ 12

Order volume = leveler volume × (1 + waste %)

Bags = order volume ÷ bag yield

Sample takeoff

A 120 ft² floor at 1/4 in average depth with 10% waste and 0.5 ft³ yield per bag needs about six bags.An 11.1 m² floor at 6 mm average depth with 10% waste and 0.014 m³ yield per bag needs about six bags.

Floor Leveling Compound Calculator FAQ

How do I calculate floor leveling compound bags?+

Multiply floor area by average depth, add waste for low spots and mixing loss, then divide by the yield per bag.Multiply floor area by average depth, add waste for low spots and mixing loss, then divide by the yield per bag.

Can I use this for feather finish patch?+

Yes if you enter the correct average depth and product yield. Very thin skim coats should use the product coverage chart.Yes if you enter the correct average depth and product yield. Very thin skim coats should use the product coverage chart.

Does this check floor deflection or moisture?+

No. Floor flatness, deflection, moisture, primer, and product limits must be checked before pouring.No. Floor flatness, deflection, moisture, primer, and product limits must be checked before pouring.
