Interface Pad Variety Pack
This pack comes with a selection of our most popular 3" X 4" interface pads. Each pad can be used for a different application.
The pack also includes the J-hook Backup Pad. If you are doing a lot of sanding with an interface pad, we recommend using the J-hook backup pad because it holds the interface pad tighter.

Includes the following:
-SPIP3X4
-SPIP3X4F7MM
-SPIP3X4F15MM
-SPIP3X4MD
-SPBP3X4J

Nous recommandons l'utilisation d'un patin de ponçage auto-agrippant pour le ponçage avec des patins d'interface. En effet, le patin d'interface ne reste pas en place lors du ponçage avec un patin auto-agrippant standard, tandis qu'un patin de ponçage auto-agrippant permet au patin d'interface de rester en place.

Interface Pads 

Four densities, three sizes, vacuum and non-vacuum options - shipped straight to all 50 U.S. states from factories in California and North Carolina. 

What Is an Interface Pad? 

An interface pad is a layer of foam that provides cushioning between the abrasive disc and the backup pad on your orbital sander. It permits flat abrasives to flex around profiles, contours, and edges while absorbing heat and preventing backup pad hooks from melting.  

Required when employing film, screen, or paper abrasives. Not required when using foam abrasives.  

SurfPrep interface sanding pads come in 3" x 4", 5", and 6" sizes that work with the whole SurfPrep orbital sander series.  

Trusted by professional finishers and cabinet shops across all 50 U.S. states (WE ARE in Canada and UK) – (this large dash looks like CHAT GPT) backed by over 15 years of surface preparation experience.

Interface pads are sometimes confused with SurfPrep ProFoam abrasives. Both give versatility to the sanding arrangement, but perform differently. With a paper or film abrasive on an interface pad, the grit cuts at its rating: 80 grit cuts like 80 grit.  ProFoam abrasives compress under pressure, pushing the grit into the foam, and cut softer than their rating indicates. An 80 grit on ProFoam will cut more like a 150 grit. Interface pads provide you with flexibility and complete cutting aggression. ProFoam provides you with maximum conformability and a softer cut. 

What SurfPrep Interface Pads Deliver 

  • Heat absorption: absorbs friction heat before it reaches the backup pad, preventing hook melt and lowering replacement frequency  
  • When a stiff backup pad by itself loses touch with profiles, moldings, shapes, and edges, surface conformability enables the abrasive to flex.  
  • Longer abrasive life: consistent pressure distribution avoids premature disc wear and gets more passes per abrasive  
  • Reduced vibration: the foam layer dampens sander vibration during extended sessions, decreasing operator fatigue and enhancing control  
  • Vacuum-compatible: available with vacuum holes in all three diameters, preserving complete dust extraction compatibility with any SurfPrep sander and HEPA dust extractor  
  • Profile work ready: pair the Soft (Grey) interface pad sander setup with a J-Hook Backup Pad for spindles, furniture legs, and tight detail areas

Interface Pad Density Guide 

Four densities available: each interface pad density is adapted to a certain surface type and sanding application: 

Pad Type Density Best For Key Characteristic
Soft (Grey) Super flexible Mouldings, profiles, spindles, detail work Maximum conformability on curves and contours
Medium Semi-firm Moderately curved surfaces, general finishing Balance of flexibility and cut aggressiveness
Firm 7mm Firm Flatter surfaces needing added flexibility Controlled conformability with moderate cushion
Firm 15mm Firm, extra cushion Maximum pad thickness applications Greatest standoff distance between sander and surface

Not sure which density to start with? The Variety Pack includes all four densities. Available separately for 3"×4", 5", and 6" sanders. 

Interface Pad Size Guide (Interface pads can fit on any other brand sander too, not just SurfPrep sanders) 

  • The most adaptable interface sanding pad size is 3" × 4". Compatible with Electric Ray 3”×4” and Storm Air 3”×4”. Ideal for tiny spaces, between-coat finishing, profiles, and detail work. Both vacuum and non-vacuum setups are available.  
  • 5” — compatible with Electric Ray Gen 2+ 5” and Trident Air 5”. Best for flat panel production sanding and cabinet doors. Vacuum holes are available.  
  • 6” — compatible with Electric Ray Gen 2+ 6” and Trident Air 6”. Ideal for production work with high demand and huge flat panels. Vacuum holes are available.

Interface Pads for Orbital Sanders 

SurfPrep Sanding’s interface pads for orbital sanders are designed especially for the random orbital action that defines orbital sanding. A flat abrasive cannot bear the heat and friction points created by the orbital pattern without cushioning; the interface pad evenly distributes this pressure over the disc to maintain constant abrasive contact throughout each pass.   

  • All SurfPrep orbital sanders, including Electric Ray (3", 3"×4", 5", 6", Storm Air, and Trident Air, are compatible.  
  • Each sanding pad is precisely sized to prevent overhang and pressure buildup at the edges.  
  • During orbital sanding, vacuum-hole alignment is maintained for continuous dust extraction across all sizes. 

Frequently Asked Questions 

What is an interface pad used for in sanding? 

An interface pad fits between the backup pad and abrasive disc, absorbing heat, protecting backup pad hooks from melting, and allowing flat abrasives to flex over profiles, contours, and edges. 

Do I need an interface pad with foam abrasives? 

No — foam abrasives have built-in flexibility, but an interface sanding pad is necessary when utilizing flat abrasives: film, screen, or paper. 

Which interface pad density should I choose? 

Soft (Grey) for curves and profiles. For general curving surfaces, medium. For flatter surfaces, use a firm 7mm or 15mm. All four are included in the Variety Pack. 

Are SurfPrep interface pads compatible with vacuum sanders? 

Yes, all SurfPrep interface pads for orbital sanders come with vacuum holes in 3" x 4", 5", and 6"; non-vacuum versions are available in 3" x 4". 

How does an interface pad protect my backup pad? 

Without an interface pad sander layer, heat from flat abrasives destroys the backup pad’s hook-and-loop fasteners — the interface pad absorbs that heat, extending backup pad life and saving replacement costs. 

Where can I buy SurfPrep interface pads in the U.S.?
