Product description

Mirka Polarshine 25 is a powerful polishing compound ideal for polishing gelcoat surfaces. Its coarse grit quickly and easily removes imperfections and sanding scratches from P800 and finer on gelcoat finishes.

Tip: for polishing painted surfaces, we recommend Mirka Polarshine 35. This more aggressive compound works more effectively on harder paint systems.

Directions for use of polishing compound for gelcoat

We recommend applying Mirka Polarshine 25 with a machine. Follow the instructions below for a perfect polishing result:

  1. Shake the bottle well before use.
  2. Ensure the surface is completely clean and dry.
  3. Put a small amount of compound on a polishing pad.
  4. Polish the surface at 800 - 2000 rpm with a rotary polishing machine
  5. Polish one section of approximately 40 x 40 cm at a time for the best result. 
  6. Continue polishing until the desired final gloss is achieved.
  7. Wipe the surface clean after polishing with a clean microfibre cloth.
Tip: when using a wool polishing pad, holograms may remain on the surface. To remove them, follow up with a Mirka Polarshine 5 (fine polishing compound).
