I have about 125 bdft of rough cut 5/4 Maple a couple years old. When I sticker'd it I threw on a couple of sandbags on top to add some weight . The bags broke (fell apart ) and covered the wood with sand. A broom helps but not enough and I hate to run it through the planner like it is. Any ideas other than hosing it off ? ( Lesson learned , never use sand bags for weight )
