Wet or Dry Sanding for Resin: What’s Best?

What’s the Difference between Wet and Dry Sanding?

Wet sanding uses waterproof abrasive paper and water to lubricate the surface, while dry sanding is performed with regular or specialised dry-use abrasives. Wet sanding helps reduce dust and minimises clogging of the paper. Dry sanding, on the other hand, creates more dust but may be preferred for quick, coarse shaping or when access to water is limited.

Choosing the Right Sandpaper for Resin

If you plan to use water during sanding, choose waterproof options such as A4 Waterproof Sanding Paper, designed for effective wet or dry use. For strictly dry sanding, purpose-made discs like the 150mm Sanding Paper Discs are an efficient choice. For projects needing both approaches, versatile pads such as the “Ebonite Abralon” Sanding Pads work well with or without water, supporting detailed finishing across various resin and wood surfaces.

When Wet or Dry Sanding Matters Most

• Wet Sanding: Ideal for minimising airborne dust and preventing abrasive clogging, especially on detailed or polished resin surfaces.
• Dry Sanding: Suited for initial shaping and quick removal where water isn’t practical or for preparation between coats.
