3M 7010401394 Floor Surfacing Roll 8in X 50yd 40 Grit

Product Description

The 3M 7010401394 is a resinite floor surfacing roll designed for use with drum sanding machines on both residential and commercial flooring jobs. The roll measures 8 inches wide by 50 yards long and is loaded with 40-grit mineral abrasive bonded to a paper or combination backing. This coarser grit is suited for initial stock removal, leveling uneven boards, and cutting through old finish or adhesive residue. Flooring contractors and remodelers install this roll directly onto drum sanders as part of a multi-pass floor refinishing sequence. At 22.25 pounds per roll, there is enough material for extended runs before a changeover is needed.

This floor surfacing roll is used in commercial and residential drum sanding applications where fast material removal is the priority. Typical scenarios include refinishing hardwood floors, surfacing gym floors, and prepping subfloors before new flooring installation. The 40-grit cut is generally the first pass in a three-stage sanding sequence, followed by medium and fine grits. The durable mineral abrasive construction is rated for the high contact pressure and heat generated by drum-style machines common in professional flooring work.

Installation Notes

Installation should be performed by a qualified flooring contractor or experienced operator familiar with drum sander operation. Disconnect the sander from power before loading or changing the roll. Ensure the roll is seated and tensioned evenly across the drum to prevent tracking or tearing during operation.
