Table 7 Mean glueline shear strength (SS) and percent wood failure (WF) of black spruce surfaces prepared by sanding using three grit size programs and three feed speeds for samples without and with an aging treatment

From: Evaluation of two surfacing methods on black spruce wood in relation to gluing performance

	Unaged samples	Aged samples	Adhesion loss (%)
SS (MPa)	9.5^a (0.1)^bA^c	7.5 (0.1)B	22
WF (%)	54 (2)a	42 (2)b	22

^aMean of 270 replicates (three sanding programs and three feed speeds pooled)
^bStandard error of the mean in parentheses
^cMeans within a row followed by the same letter are not significantly different at 5 % probability level
