How to Use This Calculator
Measure your deck area (length × width) and select wood type and condition. Choose number of coats (2 recommended). Calculator accounts for different absorption rates.
Why Accurate Deck Stain Matters
Wood type and condition dramatically affect stain absorption. Weathered and pressure-treated wood can absorb twice as much as new wood. Proper estimates prevent running short mid-project.
Common Mistakes to Avoid
Not cleaning deck before staining, applying when wood is wet, insufficient drying time between coats, staining in direct sunlight, and using interior stain outdoors.
