Area covered = length × width; Wood stain needed = ceil(length × width × coats ÷ cov × (1+waste ÷ 100)). Variables: length = length in m, width = width in m, coats = coats or layers, waste = waste allowance in %. Fixed values: cov = 10.
What do I need to enter?
You need length (m), width (m), coats or layers, waste allowance (%). Results update as you type.
