3M® Trizact PSA Sanding Strips – 3/4" x 7" | 200–1200 Grit | Box of 10

3M® Trizact PSA Sanding Strips – 3/4" x 7" | Box of 10

Achieve consistent, professional-quality sanding and precision surface finishing with 3M® Trizact PSA Sanding Strips. These premium abrasive strips feature 3M's innovative Trizact abrasive technology, designed to provide controlled cutting action, uniform scratch patterns, and dependable finishing performance.

Unlike conventional coated abrasives, 3M Trizact abrasives feature precisely engineered, three-dimensional abrasive structures that gradually expose fresh abrasive material as they wear. This technology helps maintain consistent cutting performance and produces a more uniform surface finish throughout the abrasive's useful life.

Each strip measures 3/4" wide x 7" long and features a convenient pressure-sensitive adhesive (PSA) backing for easy attachment to compatible wooden sanding sticks, sanding blocks, and other suitable backing surfaces. Simply peel off the worn abrasive and replace it with a fresh strip when needed.

Available in six abrasive grades ranging from 200 to 1200 grit, these versatile strips allow jewelers and metalworkers to progress from initial material removal to fine surface refinement before buffing and polishing.

Ideal for jewelry fabrication, precious metal finishing, scratch removal, and precision metalworking applications.

Recommended Finishing Sequence

For best results, begin with the appropriate abrasive grade for the condition of your workpiece and progressively move to finer grades:

A100 → A80 → A65 → A45 → A30 → A16 → Final Buffing & Polishing

The progressive abrasive sequence helps reduce scratches and achieve a smooth, uniform surface before polishing.

Please Note: Trizact A-grade designations are manufacturer-specific abrasive grades. The grit numbers listed are the supplied catalog equivalents and should not be interpreted as exact conventional sandpaper grit conversions.

These pressure-sensitive adhesive-backed strips require a compatible sanding stick or suitable backing surface. Wooden sanding sticks are sold separately unless otherwise specified.
