Table 2. Quantitative assessment of surface checks for each pre-treated specimen after 515 days of air drying

Treatment	Average check width (mm)	Average check length (mm)	Number of surface checks	Total area of surface checks (cm2)	Primary defect type
C	5.29	316.61	3	66.99	Splits, surface checks, end checks
ES	2.25	292.92	11	72.49	Split, surface checks, biological deterioration at the cross section
EC	3.75	268.38	5	50.26	Split, surface checks
LC	1.98	316.44	5	31.32	Suppressed surface checks, end checks

C: control, ES: end sealing, EC: end coating, LC: lateral coating.
