Work out stain coverage instantly with clear inputs, formula shown and shareable results.
Stain per coat is the area divided by the stated coverage per litre, multiplied by the number of coats, then rounded up to whole tins. Bare and end-grain timber can absorb twice the stated rate on the first coat, so quoted coverage figures are best treated as the second coat value.
Volume needed
litres = area / coverage per litre x coats
litres = area / coverage per litre x coats. Stain per coat is the area divided by the stated coverage per litre, multiplied by the number of coats, then rounded up to whole tins.
Bare and end-grain timber can absorb twice the stated rate on the first coat, so quoted coverage figures are best treated as the second coat value.
Enter area to stain, coverage per litre, number of coats, tin size. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
