36 Grit Floor Finishing Sandpaper

This 12 by 18 inch sheet uses a 36 grit abrasive for aggressive floor finishing work. The self-adhesive backing attaches directly to compatible sanding pads without separate clips or adhesives. It is sold individually for spot repairs or full-room preparation.

Self-adhesive sheet for compatible pads

The pressure-sensitive adhesive bonds to 3M Scotch Brite sanding pads so the sheet stays flat during machine sanding. No mechanical fasteners are required, freeing the pad surface for full abrasive contact. Buyers who need a hook-and-loop attachment or a different grit range should select another product.

Questions about this item

How long does the 36 grit surface stay effective when sanding a full floor?

The 36 grit coating removes material quickly on hardwood or concrete, but the sheet will dull faster on dense finishes or adhesive residue; rotate sheets to maintain cut rate.

Does the self-adhesive backing hold securely during extended sanding sessions?

The pressure-sensitive adhesive bonds firmly to compatible 3M Scotch Brite pads and resists heat buildup from continuous machine use.
