Step-by-Step: How to Remove Scratches from Epoxy Resin
Removing scratches from epoxy resin is a process that takes a little time and patience, but it’s very doable at home. Follow these steps to restore your resin’s shine.
Clean the Surface First
Always start by cleaning your resin with mild soap and water. Dry it with a microfiber cloth. This removes dirt that could scratch the resin more during sanding.
Sand Out the Scratches
- Start with the right grit: For light scratches, use 1000–1500 grit sandpaper. For deeper scratches, start at 600–800 grit, but only if necessary to avoid unnecessary abrasion.
- Wet your sandpaper: Wet sanding keeps things smooth and dust-free. Dip your sandpaper in water and gently sand the scratched area in a circular motion.
- Work up to finer grits: After the scratch is mostly gone, move to 2000 and then 3000 grit sandpaper. Always sand in circles and keep the area wet.
- Wipe clean: Use a clean, damp cloth to wipe away sanding dust.
Polish for a Glossy Finish
- Apply resin polish or plastic polish: Put a small amount on a soft cloth or buffing pad.
- Buff the area: Rub in circles with gentle pressure until the shine returns.
- Check your work: If the scratch is still visible, repeat sanding and polishing steps with higher grit.

How to Fix Deep Scratches and Gouges in Epoxy Resin
When scratches are too deep for simple sanding, you’ll need to fill and repair them for a smooth finish. Here’s how to handle those tougher jobs.
- Clean and sand the area: Use 600 grit sandpaper to smooth the edges of the gouge.
- Mix a small batch of epoxy resin: Follow package instructions carefully.
- Fill the scratch: Use a toothpick or small brush to add resin just to the damaged area. Do not overfill.
- Let it cure: Wait at least 24 hours or as directed.
- Sand and polish: Once cured, sand the area with 1000-3000 grit sandpaper, then polish for a seamless finish.
Polishing and Buffing for a Mirror-Like Shine
Polishing is the final touch that brings back the crystal-clear shine to your epoxy resin. This step is important for making your surface look brand new.
- After sanding, use a resin polishing compound or a plastic polish.
- Apply with a soft cloth or a buffing pad, and work in small circles.
- For big projects, a power buffer on low speed can save time.
- Always finish with a clean microfiber cloth to wipe away any residue.

Mistakes to Avoid When Removing Scratches from Epoxy Resin
Avoiding common mistakes will help you get the best results and protect your resin from further damage. Here are the main things to watch out for.
- Do not over-sand. Sand just enough to remove the scratch, not the whole surface.
- Do not skip grits. Moving from rough to fine sandpaper step by step prevents new scratches.
- Never use harsh chemicals. Alcohol, acetone, or strong cleaners can damage resin.
- Do not skip polishing. Sanding alone leaves the surface dull, so always polish last.

Frequently Asked Questions
Does resin polish remove scratches?
Resin polish is designed to remove fine surface scratches and bring back the gloss to your epoxy resin. It works best on shallow scratches and can also help with light scuffs. For deeper scratches, you should sand the area first before applying the polish for the best results.
Can you use nail polish remover on epoxy resin?
No, you should not use nail polish remover or acetone on epoxy resin surfaces. These chemicals can react with the resin, causing it to become cloudy, sticky, or even damaged. Instead, stick to mild soap and water or products specifically made for resin care.
What is the best scratch remover for resin?
The best scratch remover for resin is a polishing compound made specifically for plastics or resin surfaces. These products are gentle enough not to cause further damage but strong enough to remove fine scratches. Fine automotive scratch removers can also work if they are labeled safe for clear plastics.
Can toothpaste remove scratches from epoxy resin?
Toothpaste can sometimes help polish out very light surface scratches on epoxy resin because it acts as a mild abrasive. However, it is not as effective as proper resin polish or fine sandpaper for deeper or more noticeable scratches. For best results, use products made for resin to achieve a clear, glossy finish.
How do you fix cloudy spots after sanding epoxy?
Cloudy spots after sanding usually mean the surface was not polished enough to restore clarity. To fix this, use a resin polish and buff the area with a soft cloth in circular motions until the resin becomes clear again. If the cloudiness remains, repeat the polishing process with a bit more pressure or a finer polish.
