Work out varnish coats instantly with clear inputs, formula shown and shareable results.
Volume is area over coverage times the number of coats, and drying time counts the gaps between coats, which is one fewer than the number of coats. The gaps-between-coats detail is what turns a three coat job into a two day project rather than a three day one.
Volume
litres = area / coverage per litre x coats
Drying time
hours = recoat time x (coats - 1)
litres = area / coverage per litre x coats. Volume is area over coverage times the number of coats, and drying time counts the gaps between coats, which is one fewer than the number of coats.
The gaps-between-coats detail is what turns a three coat job into a two day project rather than a three day one.
Enter area to varnish, coverage per litre, number of coats, recoat time between coats. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
