When it comes to achieving smooth and polished surfaces on both metal and wood, PSA (Pressure Sensitive Adhesive) discs are a go-to choice for professionals and hobbyists alike. These versatile and efficient sanding discs are a must-have in any workshop or project space for their precision, performance, and smooth finish; we take you from 40-3000 grit!

What Are PSA Discs?

PSA discs (aka Pressure Sensitive Adhesive Discs) are adhesive-backed sanding discs that are easy to apply and remove to sander backing pads, making them an ideal choice for sanding applications on various surfaces. The pressure-sensitive adhesive backing ensures a secure attachment to sanding machines, eliminating the need for additional adhesives or tools during the sanding process.

What Are The Benefits of Using PSA Discs?

PSA (Pressure Sensitive Adhesive) sanding discs offer a simple, effective solution for a wide range of sanding tasks. Here’s why they’re a trusted choice for professionals and DIYers alike:

Easy Application: Just peel and stick. PSA discs attach quickly to your sanding tool, making setup fast and hassle-free.
Secure Bond: A strong pressure-sensitive adhesive backing keeps the disc firmly in place during use, providing smooth and consistent results.
Versatile Performance: Ideal for both wood and metal sanding, PSA discs are a go-to solution for a wide range of surface prep and finishing tasks.
Consistent Results: Even grit distribution ensures precise, uniform sanding, whether you're shaping edges or smoothing flat surfaces.
Built to Last: Made to handle demanding conditions, PSA discs offer long-lasting durability and dependable performance on challenging jobs.

Best Applications for PSA Sanding Discs

PSA discs are a versatile choice for a variety of surface preparation and finishing tasks, delivering reliable performance across multiple materials:

Metal Sanding: Ideal for removing rust, paint, and oxidation from metal surfaces. PSA discs provide a clean, polished finish on both ferrous and nonferrous metals. Benchmark Abrasives offers a range of abrasive grains tailored for different metalworking needs.
Wood Sanding: Great for prepping hardwood, softwood, and plywood. PSA discs help create smooth, even surfaces, making them perfect for sanding before painting, staining, or sealing.

From heavy material removal to fine finishing, PSA sanding discs provide the control and consistency needed for professional results.

Choosing the Right Grit

PSA discs come in various grit options, ranging from coarse to fine grits. Selecting the right grit for your sanding application is crucial for achieving the desired finish. Coarse grits are ideal for rapid material removal, while fine grits are best suited for finishing and polishing tasks.

Coarse Grits: 40-60
Medium/Coarse Grits: 80-100
Medium Grits: 120-150
Fine Grits: 180-220
Very Fine Grits/Finishing: 240 and up

When to Choose PSA Discs Over Hook & Loop

PSA (Pressure Sensitive Adhesive) discs feature a sticky backing—similar to a strong sticker—that adheres directly to your sander's pad. To use one, simply peel off the protective liner and press the disc onto the pad. PSA sanding pads are typically more budget-friendly than hook and loop options, making them an attractive choice for cost-conscious workflows.

However, PSA discs come with a trade-off. Once removed, the adhesive backing is prone to picking up dust, debris, or oils from your hands, which can compromise its ability to stick again. For this reason, PSA discs are best suited for applications where grit changes are infrequent or where tools are dedicated to a specific grit.

If your project requires switching between grits regularly—and you don't have separate sanders set up for each grit—hook and loop discs are the more efficient and durable option. They allow fast changes without compromising performance or wasting material.
