Tru-maxx SPPC158N1 Sanding Sponge Hard Silicon Carbide 150 80 Grit

Product Description

The TRU-MAXX SPPC158N1 is a double-sided silicon carbide sanding sponge designed for surface preparation, finishing, and material removal across a wide range of substrates. Measuring 4 inches wide, 2-3/4 inches long, and 1 inch thick, it delivers two grit options in a single block: 150 grit on one face for finer finish work and 80 grit on the opposite face for more aggressive stock removal. The silicon carbide abrasive is well-suited for hard materials including tile, stone, fiberglass, and painted surfaces. The flexible sponge backing conforms to contours and flat surfaces alike, making it practical for both hand-finishing and detail work. At 0.065 pounds, it is lightweight and easy to control during extended use.

This sanding sponge is used in construction, renovation, and finishing applications where dual-grit flexibility reduces the need to swap between multiple abrasives. The 80 grit side handles initial material removal, scuffing, and paint stripping, while the 150 grit side is used for intermediate finishing passes and surface smoothing before priming or coating. It is commonly used by finish carpenters, painters, tile setters, drywall contractors, and general tradespeople. Its compact block format is well-suited for tight spaces, corners, and curved trim profiles where sheet abrasives are difficult to control.

Installation Notes

No power tools or special equipment are required - this sponge is intended for hand use only. Apply consistent, even pressure across the sanding face to prevent uneven abrasion. Rinse the sponge with water between uses if working on wet or damp applications, and allow it to dry fully before storage. Always wear appropriate respiratory protection when sanding materials that generate fine dust.
