🧼 Step-by-Step: Light Sanding & Polishing Epoxy
🪵 1. Start with a Clean, Cured Surface
- Make sure the epoxy is fully cured (usually 72+ hours depending on brand).
- Wipe off any dust or debris with a lint-free cloth.
🧽 2. Wet Sanding (Recommended)
Wet sanding reduces heat and dust, giving you a smoother finish.
- Materials:
- Sandpaper grits: 600 → 800 → 1000 → 1500 → 2000
- Spray bottle with water + a drop of dish soap
- Soft sanding block or foam pad
- How to:
- Spray the surface and sandpaper with water.
- Sand in gentle, circular motions.
- Rinse and wipe between grits.
- Don’t skip grits—each one removes the scratches from the last.
💡 Tip: If the surface is uneven or has drips, start with 400 grit—but only if needed.
✨ 3. Polishing
Once the surface is smooth and matte from sanding, it’s time to bring back the shine.
- Materials:
- Plastic or automotive polishing compound
- Microfiber cloth or buffing pad
- Optional: drill with polishing attachment for larger pieces
- How to:
- Apply a small amount of polish to the surface.
- Buff in small circles until the surface becomes glossy.
- Wipe clean with a dry microfiber cloth.
💡 Tip: For a mirror finish, repeat with a finer polish or swirl remover.
🧴 4. Optional: Seal or Wax
This helps prevent yellowing and adds a buttery-smooth feel.
For added protection, apply a resin-safe wax or UV-resistant topcoat.
