One of the most frustrating things to deal with is a cracked epoxy resin. It may seem like it’s impossible to fix, but if you follow these steps and use the right tools and materials this repair will be easy peasy!
How Do You Fill Epoxy Cracks?
There are a few different ways to do this, depending on your preference and the type of crack you have.
First, let’s look at three types of epoxy resin cracks: hairline fractures, chip or gouge repairs, large surface area damage.
Hairline Fractures: these tiny little lines can be filled with an easy-to-use adhesive like Gorilla Epoxy Super Glue, available in most hardware stores.
You simply mix equal parts together and use it as filler over the crack filling it up completely! Use something flat (like a credit card) to scrape excess off.
Let this dry overnight and use a sanding block to smooth it out the next day!
Chip or Gouge Repairs: let’s say you dropped your epoxy resin, stepped on it, or got some type of deep gouges in the surface that are making it look dull and discolored.
When you’re dealing with larger areas like these it is recommended to use epoxy putty instead of glue because they will provide way more strength than most glues can offer.
You may also need something like wood filler if there is noticeable damage under the area where you applied the new layer but don’t worry, we’ll cover all this below!
Large Surface Area Damage: I’m sure everyone has been in this situation, you have a nice piece of epoxy resin that has taken a beating and now there are chunks missing from the surface.
The first thing to do is take into account how big these areas are so we can determine what type of filler material to use.
If they’re fairly small pieces not bigger than an inch each then wood filler should work just fine! It dries clear which means it won’t change the color or sheen of your project but if you want something absolutely invisible to the eye go with Bondo Spot Putty.

How Do You Fix Cracks In Resin?
The best way to fix cracks in epoxy resin is with an epoxy putty like Bondo Spot Putty.
This works great for both large and small areas, even filling hairline fractures! Just mix equal parts of the yellow and gray stuff together until it’s a uniform shade, apply over the crack making sure you push down hard so it fills the area completely, and then let it dry overnight.
Use a sanding block or another tool to smooth out your surface in the morning!
How Do You Fix A Bad Epoxy?
This is the worst-case scenario and in my opinion, pretty much impossible to fix. If your epoxy resin has just turned bad there’s nothing you can do about it but dispose of it properly (check with your local recycling center) or try using leftover resin for something else like candle holders!
How Do You Keep Epoxy From Cracking?
The best way to keep your epoxy resin from cracking is by using it correctly! This means making sure you are fully aware of the instructions on how long it takes to cure, what type of conditions will make them not work well (temperature changes for example), and if there are any special tools or materials required.
Remember that one layer of epoxy resin is never enough! You will always need at least two and sometimes even three layers to make the project strong and durable.
If you’re using wood glue instead of epoxy (like Gorilla Glue) be especially careful about making sure it is completely dry before applying another layer on top or else your entire piece may collapse!
Can You Fill Wood Cracks With Epoxy?
You can fill hairline fractures or small chips/gouges in wood with epoxy using the adhesive Gorilla Epoxy Super Glue. Just mix equal parts together and apply over cracks, let dry overnight then use a sanding block to smooth it out!
Can You Fix Cracked Rubber With Resin?
Yes, this is possible but it is not recommended as the rubber may become too brittle and crack again. If you must, use epoxy putty to fill cracks in your rubber but be aware it won’t withstand any type of flexing or movement so only use it for decorative purposes!
How Do I Fix A Broken Vase With Resin?
This will depend on how big the crack is and what type of vase it is. If you have a small chip/scratch on your glass piece try filling with wood filler, let dry overnight then sand smooth in the morning! For larger cracks use an epoxy putty like Bondo Spot Putty or Gorilla Epoxy Super Glue to fill them completely.
What To Use To Fill Cracks In Wood?
When it comes to filling cracks in wood there are several options depending on the size of your crack. You can use paintable latex caulk or even glue, but if you want something more heavy duty go with Bondo Spot Putty which dries clear and doesn’t change the color or sheen of your project!
Why Did My Resin Crack?
This is most likely because your resin didn’t cure completely. Check the instructions for how long to let it set, what temperature changes will affect its curing time (such as heat or cold), and if there are any special tools/materials required!
Does Resin Crack Easily?
Resin is very hard and durable but if you’re not using it correctly or aren’t making layers thick enough then yes, your project will crack.
Make sure to read the instructions on how long curing times take (especially after temperature changes like heat), what type of materials must be used in conjunction with them, and any tools needed!
Can You Spot Fix Epoxy?
You can use epoxy putty for this, Gorilla Epoxy Putty is great because it dries fast and doesn’t shrink upon drying so you won’t have to sand much!
Can You Pour Epoxy Over Cured Epoxy?
This will depend on the type of epoxy you’re using. Polyurethane resin or general purpose acrylic resin can be poured over the top but polyester and fiberglass resins should never touch as they won’t bond together properly!
What Materials Do I Need To Use With Wood Filler?
You don’t necessarily have to do anything, but if you want the crack filled completely then use a putty knife to pack wood filler into it, let dry overnight then sand smooth in the morning!
What Happens If You Add Too Much Hardener To Epoxy?
This will depend on the type of epoxy you’re using. If it’s polyester resin or fiberglass, your project may fail completely as the hardener is what makes them strong! Polyurethane and general purpose resin can be poured over if too much was used but this isn’t recommended either because they usually won’t bond properly to the epoxy.
