Ever finish painting a part or repairing your floor only to notice sanding scratches hard to reach under the hood. I know this pain is all too familiar.
Well, that’s where I come in. I want to show you how to remove sanding scratches from epoxy.
After glancing over this article, you’ll be well on your way to removing sanding marks from epoxy and getting your project looking great.
How do you remove scratches from epoxy?
This is the most common method of removing scratches from epoxy resin. Here’s how to do it:
- Start by using very fine grit sandpaper (400-600)
- Work in a regular pattern, across the scratch, and over it again, until you can no longer feel the scratch with your fingernail. Repeat for every scratch that you want to remove.
- Once all of your scratches have been sanded away, use a slightly finer grit to make sure that there are no rough bits remaining.
Polishing compound or polish is probably the most effective method for removing scratches from epoxy resin.
It won’t work on deep scratches, but it can be used on smaller markings and will leave your surface-looking mirror-smooth when finished. You can buy polishing compounds at any hardware store; follow their instructions for application carefully. Acetone
Acetone is also an excellent option for removing scratches from an epoxy resin surface because it will get into even small imperfections and smoothen them out completely.
After using acetone to smooth out your surface, if any residue remains behind you can simply wipe it up with water and dry the surface thoroughly before using it again.

How do you make epoxy shiny again after sanding?
It’s easy to make your epoxy flooring look shiny and new again after sanding. You can use car compound and a buffer or drill with a buffing wheel attachment.
If you want to give the epoxy floor a mirror finish, use a polishing wheel (like the ones used on a car) attached to your drill and apply wax polish as an alternative solution.
Also, you can just buy special products meant specifically for this purpose (e.g., 3M Marine Restorer & Wax or Turtle Wax T-478R Liquid Polish).
Will epoxy cover sanding scratches?
Sanding scratches are one of the most common issues that epoxy users will encounter. They can make your surface look unsightly and cause problems with the next layer of epoxy.
Surface prep is a crucial step in the epoxy application process, so it’s important to understand why sanding scratches happen and how to avoid them in the future.
To prevent sanding scratches, there are a few things you need to know:
- Sanding scratches occur when you apply too much pressure with your sander
- If you don’t use an appropriate grit, you could create more sanding scratches than desired
- Using a softer pad or backing for your soft pad sander can help prevent deep gouges from aggressive abrasive discs
Can you polish scratches out of resin?
This is one of the most common questions I get when people discover that I do woodworking and have a YouTube channel.
They have some projects they’ve made using resin on top of it, which has scratches and dulled finish. They almost always ask me to make a video on how to remove sanding scratches from their resin/epoxy projects. Now, we’re going to look at exactly how you do that!
If you used sandpaper on your project with epoxy or resin, chances are, you’re going to end up with some sanding scratches in it.
When you put a clear coat over that scratch, those will show up because light is bouncing out of the scratch instead of off of the clear coat like the flat surface surrounding it, showing as an imperfection.
To fix this issue and remove these scratches from epoxy (or any other type of finishing product), start by getting some sandpaper sheets in the same grit size that you used initially when sanding your project before applying finish.
Wet sand using lubricant (soapy water) and circular motions until all surface scratches have been removed and the surface is repaired back to its original smoothness.
Can epoxy resin be sanded?
You can sand epoxy, but there are a few things you should know before doing so. If you need to remove bubbles or smooth a surface, sanding is a possibility if done correctly.
However, it’s important to understand how and why epoxy resin should be sanded in order to avoid damaging it.
Can epoxy be scratched?
The short answer, unfortunately, is: yes. Like most other materials in the world, epoxy can be scratched.
In a more complex way, here’s how it works: Epoxy has a hardness rating of 9/10 on the Mohs scale. The Mohs scale is used to measure the hardness of various minerals, and essentially it’s what we use to see how easy or difficult it is for one material to scratch another.
We know that 10 is the hardest on this scale so anything with a rating lower than 10 will eventually be able to be scratched by something on the list like a diamond (10), corundum (9), topaz (8), quartz (7), or calcite (3).
Epoxy has an incredibly high hardness rating but that doesn’t mean you won’t encounter scratches if you use it in your home or workspace! Scratches can happen from day-to-day wear and tear as well as from drastic objects coming into contact with your surface.
While it might not easily show up on your countertop if you accidentally run a knife along its edge while chopping veggies, one big enough bump could definitely cause some damage.
Can you use Windex on epoxy?
Can you use Windex on epoxy? You can use Windex to clean your epoxy. However, it is not the most effective method for removing sanding scratches, and should only be used for low spots that don’t require wet sanding or buffing.
Instead of using Windex, wipe your surface down with a soft cloth and water to remove dust and debris before applying additional layers of epoxy.
How long until you can sand epoxy resin?
If you want to know how long until you can sand epoxy resin, it depends on a few factors, like:
- the type of epoxy resin you used (for example ArtResin is much harder after curing than most other brands)
- the amount of epoxy resin mixed and applied (a thin layer cures more quickly than a thick one)
- temperature and humidity (the warmer your environment, the faster your epoxy will cure; humidity slows down the curing time dramatically)
Thus, you have learned the best ways to remove sanding marks from epoxy. Use these techniques and your hard work will no longer be marred by those pesky sanding scratches.
