3M 7000119279 Sanding Sheet 150 Grit 3x4 in Aluminum Oxide

Product Description

The 3M 7000119279 is a coated abrasive sanding sheet designed for dry hand sanding and finishing applications in trade and industrial settings. Built on a C-weight paper backing, this sheet uses aluminum oxide abrasive at 150 grit for fine-grade material removal and surface prep. The open coat density reduces loading and extends usable sheet life. At 3 inches wide by 4 inches long, it fits standard hand sanding blocks and is well suited for finish work on wood, metal, and composite surfaces. HVAC fabricators, electricians, plumbers, and general tradespeople use sheets like this for deburring, surface conditioning, and pre-finish prep on job sites and in shops.

The 236U series sheet is intended for dry sanding only and carries a load-resistant treatment that helps prevent clogging when working softer or resinous materials. The 150 grit fine grade makes it appropriate for intermediate to finish sanding passes rather than aggressive stock removal. It is sold individually but requires a minimum order quantity of 50 units. Typical applications include surface prep before priming or coating, light deburring of cut edges, and cleanup of weld spatter or oxidation on metal components.

Installation Notes

No power tools or electrical shutoff procedures are required for hand sanding sheets. Secure the sheet firmly to a sanding block before use to maintain even pressure and prevent edge tearing. Use only in dry conditions as this sheet is not rated for wet or lubricated sanding. Dispose of loaded or worn sheets promptly to maintain consistent finish quality.
