SPACER PROTECTIVE INTERFACE Ø 150 MM 4 MM FOR GALAXY 5/BOX*

What is the Mirka Spacer Protective Interface Ø150 mm 4 mm for Galaxy and why choose it?

The Mirka spacer protective interface Ø150 mm, 4 mm thick, is a net-type interface pad designed to be used between the backing pad of your sander and 150 mm Mirka Galaxy abrasive discs. Its main functions are to increase flexibility on contoured surfaces, improve sanding comfort and finish, and protect the backing pad from wear, especially in intensive collision repair and marine applications.

Thanks to its spacer construction and 4 mm thickness (data not verified against the official technical datasheet), it helps distribute sanding pressure more evenly and supports efficient dust extraction when used with Multifit Galaxy discs.

Main features

• Diameter 150 mm – sized for standard 150 mm orbital sanders and 150 mm Mirka Galaxy discs.
• Approx. thickness 4 mm – spacer interface that increases cushioning between disc and backing pad (thickness not verified against the official datasheet).
• Protective function – helps protect the sander backing pad from damage and premature wear.
• Optimised for Mirka Galaxy abrasives – acts as a base for 150 mm Galaxy sanding discs, supporting their cutting performance and dust extraction.
• Improved flexibility – allows better adaptation to curves and profiles, reducing the risk of sanding through edges when working on shaped panels.
• Net / spacer construction – designed to maintain dust extraction performance while adding cushioning (construction details not fully verified).
• Pack of 5 units – the description “5/BOX” indicates a box containing 5 spacer interfaces.

Technical specifications

• Brand: Mirka
• Product type: Spacer protective interface / net interface pad
• Diameter: 150 mm
• Approx. thickness: 4 mm (not verified; recommended to check the official Mirka technical datasheet)
• Format: Round disc interface
• Recommended abrasive type: Mirka Galaxy 150 mm discs
• Packaging: 5 pieces per box

Applications and use cases

• Automotive collision repair: Intermediate interface when sanding fillers, primers, and paint with Galaxy discs on curved car body panels.
• Marine finishing: Sanding of gelcoat and marine coatings on hulls and curved surfaces where extra flexibility and pad protection are required.
• Industrial and wood applications: Use with 150 mm Galaxy discs on wood, composites or synthetic materials where a finer, more controlled finish is needed on profiles and edges.
• Backing pad protection: Daily workshop use to minimise wear, scratches and damage to the sander pad when frequently changing discs.
• Improved comfort and finish: The spacer effect can reduce vibration transfer to the operator’s hand (not measured; perception may vary) and helps achieve a more uniform surface on contoured parts.

FAQ

1. 1. What is this spacer protective interface used for?

   It is used between your 150 mm backing pad and 150 mm Mirka Galaxy discs to protect the pad, improve flexibility on contoured surfaces and support efficient dust extraction.

2. 2. Is the 4 mm thickness exact?

   The product name indicates 4 mm thickness, but this data has not been verified here against the official Mirka datasheet. For critical applications, check the manufacturer’s official technical documentation.

3. 3. Can I use it with other abrasives or only with Galaxy discs?

   It is optimised as a spacer interface for Mirka Galaxy 150 mm discs, but in practice it can usually be used with other 150 mm hook-and-loop discs of similar hole configuration. Compatibility should be checked for each abrasive.

4. 4. Does it affect dust extraction?

   The spacer design is intended to maintain dust extraction performance when used with Multifit Galaxy discs, but exact airflow performance has not been verified here. Always ensure correct alignment of disc, interface and backing pad holes.

5. 5. How many spacer interfaces are included per box?

   The designation “5/BOX” indicates that the box contains 5 spacer protective interfaces.

6. 6. Is this product compatible with all 150 mm Mirka backing pads?

   It is designed for use with 150 mm Mirka backing pads and Galaxy discs. However, exact compatibility with specific pad models is not verified here, so checking the official Mirka documentation is recommended.

7. 7. Does using the spacer change the sanding result?

   Yes, the additional cushioning can make the sanding action slightly softer, which is often beneficial on curves, edges and when a finer finish is needed.

8. 8. Can it be reused?

   Yes, the interface pad is reusable and typically lasts through multiple abrasive disc changes, depending on the working conditions and care.

9. 9. Is this product suitable for wet sanding?

   The suitability for wet sanding is not specified here. If you plan to sand with water or lubricants, it is advisable to confirm this point in the official Mirka technical datasheet.

10. 10. Do I still need a backing pad if I use this spacer?

    Yes, this spacer is used on top of a standard backing pad; it does not replace the backing pad.

Section 14 – Transport information

This product is a solid accessory for sanding equipment and is not classified as a dangerous good for transport based on the information available. No specific transport hazard class, UN number, packing group or special transport conditions are indicated in the information consulted. For professional or large-volume shipments, it is recommended to confirm any applicable transport requirements in the official documentation of the manufacturer or in the safety data information supplied with the product, if available.

Section 8 – Individual protection measures

The spacer protective interface itself does not introduce additional specific hazards, but it is used in sanding operations that generate dust and noise. During these operations, the following personal protective measures are generally recommended:

• Eye protection: Use safety glasses or goggles to protect against dust and particles projected during sanding.
• Respiratory protection: Use an appropriate dust mask or respirator when sanding, especially in poorly ventilated areas or when working on materials producing fine or harmful dust.
• Hand protection: Wear suitable work gloves when handling tools and discs to reduce the risk of cuts, abrasions and vibration exposure.
• Hearing protection: When using power sanders, apply hearing protection (earplugs or earmuffs) according to the noise level of the equipment.
• Work clothing: Use workwear that covers the skin and, if necessary, disposable or washable overalls to avoid dust accumulation on clothing.

The exact personal protective equipment required may vary depending on the substrate, environment, and local occupational safety regulations. For precise and binding information, consult the official Mirka safety and technical documentation and applicable workplace regulations.
