Gelcoat Liquid Sanding

Liquid sanding paper to prepare the gel coat

Unleash the power. Liquid sanding is a groundbreaking innovation from Menzerna. This liquid sandpaper vigorously treats highly scratched, soiled, and crusted gel coats. Liquid sanding smooths out areas in need of repair. The perfect surface preparation to facilitate subsequent polishing.

Preparation of the gel coat

More information

  • High-quality sanding powder, extremely easy to use
  • Even sanding pattern
  • Clean sanding pattern, even on contours
Recommended usage
  1. Before using: Clean the surface well.
  2. Shake the bottle and apply the product on the pad or abrasive fleece.
    Please note here: the larger the pad (or abrasive fleece), the more Gelcoat Liquid Sanding you need.
  3. For surface preparation, use the Menzerna Lambswool Pads (optional: Menzerna Heavy Cut Foam Pad) together with a rotary polishing machine or use a sanding fleece by hand.
  4. If you are using a rotary polishing machine (low machine speed and apply strong pressure), work in a cross-pattern and if polishing by hand do it in circling movements.
  5. Work out the product until the dirt on the surface is removed.
  6. Remove the residue with a microfiber cloth.
  7. The surface is now prepared and the polishing marks can be removed with the Gelcoat Premium One-Step Polish.
