Sanding Sheet 11 in x 9 in P400

These sanding sheets measure 11 inches by 9 inches and come in a pack of 100. The abrasive is aluminum oxide on a B-weight paper backing. They are graded P400 for super-fine finishing work.

Ideal for final wood or metal prep

Suited for painters and woodworkers who need a smooth surface before applying finish. Not intended for heavy stock removal or shaping tasks that require coarse grits. Buyers who want aggressive cutting should look at lower grit options.

P400 grit aluminum oxide abrasive

The P400 grade defines the cutting fineness and surface quality this pack delivers. Aluminum oxide provides consistent performance on wood, metal and painted surfaces. Verify the grit matches the finishing stage your project requires.

Questions about this item

What size sanding block or pad fits the 11 in by 9 in sheets?

The sheets measure 11 inches long by 9 inches wide, so a standard 9 x 11 hand-sanding block or half-sheet orbital pad will hold them without trimming.

How do I attach these paper-backed sheets so they don't slip during use?

Wrap the sheet around the block and clamp the ends under the tension clips, or use spray adhesive on the paper backing; the B-weight paper tears if you over-tighten mechanical clamps.

When should I replace a sheet while working through the 100-pack?

Switch to a fresh P400 sheet once the aluminum-oxide grains dull and the red backing shows through — usually after several panels or when the cut rate drops noticeably.
