Abstract

End coatings are typically used to help prevent end checks on sawn lumber during the drying process. These drying defects can cause a loss of valuable lumber. This study was conducted to look at the effectiveness of three different types of end coatings. After 1 year of air-drying, boards with each of the three end coatings were compared with each other, and they were also compared with untreated control boards. Although all three end coatings were found to be effective in decreasing the amount and severity of drying defects compared with the untreated controls, there were no significant differences in effectiveness among the three types of treatments.
