POLARSHINE 35 POLISHING PASTE

What is Mirka Polarshine 35 Polishing Paste and why choose it

Mirka Polarshine 35 Polishing Paste is a coarse, water-borne, silicone-free polishing compound designed for demanding industrial and marine applications. It is formulated to remove heavy defects and sanding scratches on hard surfaces such as gel coats, high-gloss lacquers and composites, while delivering a high surface gloss and reducing the number of sanding steps required. Thanks to its special emulsifying properties and controlled viscosity, Polarshine 35 is easy to work with, minimizes splashing and helps reduce the risk of drying out or overheating the surface.

Main features

• Coarse cutting action for rapid removal of sanding scratches from approximately P800 and finer, or for restoring heavily oxidized surfaces.
• Developed for demanding industrial and marine use, ideal for professional applications on boats, industrial components and high-gloss coated parts.
• High surface gloss: fast and efficient polishing compound that leaves a bright, glossy finish and helps minimize the number of sanding and polishing stages.
• Water-borne and silicone-free formula, suitable where silicone contamination must be avoided (for example, before repainting).
• Special emulsifying properties reduce the risk of the product drying on the surface or causing overheating during machine polishing.
• Optimized viscosity significantly lowers splashing and makes the compound clean and easy to use, especially with machines.
• For machine application, typically used with twisted wool or foam polishing pads depending on the sanding grit and desired finish.

Applications and use cases

Typical applications

• Marine sector: Polishing of gel coat on hulls, decks and superstructures, removal of heavy oxidation and sanding marks after repair or refinishing.
• Industrial finishing: High-gloss composite parts, coated panels and industrial components requiring an even, glossy finish after sanding.
• Automotive and transport: Correction of severe defects on hard clearcoats and composite body parts, especially where sanding up to around P800–P1000 has been carried out.

Typical tasks

• Rapid removal of sanding scratches from about P800 and finer, depending on pad and technique.
• Restoring shine on heavily oxidized or weathered high-gloss surfaces.
• Reducing or removing fine orange peel texture on hardened coatings (always test first on a discrete area).
• First step in a multi-stage polishing system before moving to finer Polarshine compounds for final gloss and hologram removal.

For best results, always follow Mirka’s latest application recommendations and adapt machine speed, pad type and pressure to the specific surface.

FAQ

1. What type of product is Mirka Polarshine 35 Polishing Paste?

It is a coarse, water-borne, silicone-free polishing compound designed for demanding industrial and marine polishing tasks, especially on gel coats, high-gloss lacquers and composites.

2. On which surfaces can I use Polarshine 35?

It is generally suitable for gel coats, high-gloss lacquers, composites and similar hard, glossy coatings. Always test on a small, inconspicuous area first to confirm compatibility with the specific substrate.

3. Is Polarshine 35 suitable for removing sanding scratches?

Yes. It is formulated to remove sanding scratches from approximately P800 and finer, depending on the pad and technique used, and is often used after heavy sanding or defect correction.

4. Does it contain silicone?

According to manufacturer information, Polarshine 35 is silicone-free, which is beneficial in environments where repainting or subsequent coating steps are planned.

5. Is this product intended for manual or machine polishing?

It is primarily intended for machine application and is commonly used with twisted wool pads for maximum cutting or foam pads where a more controlled finish is required.

6. Does Polarshine 35 produce a high-gloss finish?

Yes. Although it is a coarse compound, it is designed to produce a high surface gloss and to reduce the number of sanding and polishing steps needed. In some workflows it is followed by a finer compound to refine the finish further.

7. Can it dry out or overheat the surface during polishing?

The formulation includes special emulsifying properties that help reduce the risk of drying out or overheating the surface when used correctly, but suitable machine settings and working technique are still important.

8. Is Polarshine 35 classified as hazardous?

According to available safety data sheets, the mixture is not classified as hazardous under the applicable regulations, although repeated exposure may cause skin dryness or cracking (EUH066). Always follow the latest safety data sheet and local regulations.

9. Do I need personal protective equipment when using this product?

Yes. Basic PPE such as suitable gloves and eye protection is recommended when handling and machine-applying the compound. Exact requirements depend on your local safety rules and the latest safety data sheet, which should always be consulted.

10. Where can I find complete technical and safety details?

For precise and up-to-date information on composition, safe handling, storage and performance limits, consult the official Mirka technical data sheet and safety data sheet for Polarshine 35.

Section 14 – Transport information

According to available safety data sheets, Polarshine 35 Polishing Paste is not classified as a dangerous good for transport under ADR/RID, IMDG or IATA regulations (non-hazardous for transport). This means it is generally shipped as non-dangerous cargo under normal conditions. Nevertheless, packaging must be kept closed and protected from strong heating, and local and carrier-specific requirements must always be observed.

Section 8 – Personal protective measures

The following information is a simplified summary derived from safety data sheet recommendations and should be verified in the latest official SDS before use:

• General advice: Avoid prolonged or repeated skin contact and prevent the compound from contacting eyes. Do not ingest and avoid inhaling mist or spray during machine polishing.
• Hand protection: Use suitable protective gloves resistant to chemical products and cleaning agents, especially for repeated or prolonged contact.
• Eye/face protection: Wear safety glasses or a face shield during machine application to protect against splashes.
• Skin and body protection: Wear work clothing that covers exposed skin; in heavy-duty or overhead work, consider additional protective garments.
• Respiratory protection: Under normal, well-ventilated conditions, respiratory protection is often not mandatory, but in poorly ventilated areas or where aerosol/mist may be generated, use an appropriate respiratory mask as specified in the SDS and local regulations.
• Hygiene measures: Wash hands and exposed skin after use and before breaks; do not eat, drink or smoke while using the product. Apply skin care products after washing to counteract possible dryness (EUH066: repeated exposure may cause skin dryness or cracking).
