Boxplot, the line in the box illustrates the median MC of five boards. The top and bottom of the box present the 25th and 75th percentiles, meaning 25% of the values are below the 25th percentile and 25% are above the 75th percentile. Approximately 95% of the values are expected to be within the upper and lower limits of the whiskers. The individual replicates highlighted with numbers in the graph (number 20, 22, 46, 52, 72 and 73 described in Table 1) are outliers, circles had 1.5–3 times higher or lower values than the height of the box (25th–75th percentile), and asterisks had values more than three times higher or lower. A–D: coating systems described in Table 2
