About this calculator
Overview
Staining your deck not only enhances its appearance but also provides vital protection against UV rays and moisture. This calculator helps you determine how much stain to purchase, accounting for the floor, railings, and stairs. Most standard stains cover between 200 and 300 square feet per gallon for the first coat.
💡
Pro Tips
Always buy about 10% more stain than calculated to account for spills and touch-ups.
Clean your deck thoroughly with a deck cleaner before applying any stain.
Test a small, inconspicuous area first to ensure you're happy with the color.

Fun Facts
"New wood often absorbs more stain than older, weathered wood."
"Staining should ideally be done when the wood is dry and the temperature is between 50°F and 90°F."
"Quality stains can last 2-3 years on the floor and even longer on railings."
Formula: Total Area = Floor Area + Railing Area + Stairs Area; Gallons = (Total Area × Coats) / (Coverage per Gallon)
