Estimate how much wood stain a deck or fence needs.
Total stain area is the surface times the coats, divided by how much a gallon covers to find the gallons needed, and shown as a quart equivalent for small jobs. Stain coverage depends on how dry and porous the wood is, so checking coverage avoids buying far more or far less than the job needs.
Wood Stain Coverage
Gallons = surface area x coats / coverage per gallon
