Frequently Asked Questions
What coverage rate should I use?
175 square feet per gallon is a commonly cited coverage figure for deck stain on wood, though this varies by product and by how porous or weathered the wood is. Check your specific stain product label for its stated coverage rate.
Does this include railings, balusters, or stair risers?
No, this calculates the flat deck floor area only. Railings, balusters, and stairs add significant additional surface area and should be estimated separately and added to the total.
Why do I need more stain for a second coat than the floor area alone suggests?
The first coat often soaks into the wood grain more than the second, but this calculator uses the same coverage rate per coat for simplicity. In practice a first coat sometimes uses somewhat more product than later coats on the same surface.
