The Sanding Process
Following 7 days curing the deck is ready for sanding. Prior to that, however, excess cured Sikaflex 29 DC should be removed with a sharp chisel or knife. This procedure will avoid excess pullon the edges of the seams during the subsequent sanding operation. For effective sanding results use an industrial sander. It is recommended to begin with a medium (80) progressing to a 120 grit or finer. Suitable sanders are beltsanders, flat plate sanders or elastically suspended sanders. Sanding should be along the direction of the seams.
