Marine paint consumption calculator
Calculate marine paint quantities from area, dry film thickness, volume solids, coats and losses. Switch between metric and imperial units.
How much paint does the job actually take?
Area, DFT, volume solids, loss factor. The gap between theoretical and practical consumption is where jobs go over budget - so dial in the loss factor honestly, not optimistically.
// theoretical spreading rate
SR (m²/L) = VS% × 10 ÷ DFT = 18.8
// practical consumption
V = AREA × COATS ÷ SR ÷ (1 − LOSS)
= 5,000 × 2 ÷ 18.8 ÷ 0.65 = 820 L
SR (m²/L) = VS% × 10 ÷ DFT = 18.8
// practical consumption
V = AREA × COATS ÷ SR ÷ (1 − LOSS)
= 5,000 × 2 ÷ 18.8 ÷ 0.65 = 820 L
