The amount of stain needed to cover a 900 sq ft deck typically depends on the type of stain and the surface's porosity. On average, one gallon of stain covers about 200 to 300 sq ft. Therefore, for a 900 sq ft deck, you would likely need 3 to 4.5 gallons of stain, so purchasing 4 to 5 gallons is advisable to ensure full coverage. Always check the manufacturer's instructions for the specific product you are using.
