Epoxy is a type of strong adhesive, so you might guess that epoxy resin works as an excellent glue. However, it’s not always the best choice to use one epoxy product as glue for another.
To help clarify this issue, let’s start with a quick overview of what exactly epoxy resin is (and is not).

Will epoxy bond to cured epoxy?
Epoxy is a very versatile glue that can be used for a variety of applications. It’s one of the strongest and most durable glues available today.
In fact, it’s so strong that you’ll often see it used in construction projects involving large pieces of steel or concrete (like bridges).
Epoxies are rarely 100% solids; they have some liquid content that allows them to flow easier when applied between two surfaces being glued together.
This also helps prevent cracks from forming as pressure is applied during curing due to contraction at room temperature versus outdoor temperatures where curing takes place (you can read more about this here).
Can you put a second coat of epoxy?
You can absolutely apply the second coat of epoxy over an existing layer of epoxy. Just make sure that the first coat has fully cured before starting.
Wait at least 24 hours between coats, and make sure you’re applying the second coat in a well-ventilated area with good lighting conditions to ensure that it goes on evenly.
Also, be careful not to get any old paint or dirt stuck in the fresh epoxy as this could cause problems when you go back for another layer later on!
How do you pour epoxy over epoxy?
You can pour epoxy over existing epoxy, but it has to be done properly.
- Clean the surface you’re going to adhere to your new coat of resin as thoroughly as possible before applying the first layer of resin and hardener. This will help ensure a good bond between the two layers, which is essential for preventing peeling or cracking later on.
- Mix up enough resin for both layers at once so that there isn’t any air in either batch when you pour them together (air bubbles will cause bubbles in your finished product). If you do not have enough of one component left from when you mixed your last batch, make sure it is mixed thoroughly before adding more hardener or thinner to bring both liquids up to their correct viscosity (thickness).
Can you put new epoxy over an old epoxy floor?
The answer to this question is yes! You can apply new epoxy over an old epoxy floor. But you need to make sure that the old floor has fully cured before applying the new layer of epoxy.
If you’re going to do this, clean off all of the old floorings with a mixture of acetone and water. This will allow for better adhesion between layers and prevent peeling or lifting later on down the road.
How do I fix messed up epoxy?
If you find yourself with a mess, don’t panic. You can fix it if you take the following steps:
- Clean up your mess immediately. Remove all of the epoxies that’s been applied and then clean up any residue with soap and water.
- Remove any residual adhesive that remains in the area where you want to put your new epoxy coat. This will ensure a good bond between layers of epoxy and prevent peeling or flaking later on down the road.
- If possible, apply another layer of primer before applying another coat of finish over top of whatever area was previously coated by an inferior product (or no product at all!). This will help prevent future problems from occurring due to improper application techniques used by those who did not know better before now!
Can you pour epoxy over uncured epoxy?
Yes, you can pour epoxy over uncured epoxy. This is a very simple process and can be done in two ways:
- Pour the new layer of epoxy right on top of the cured layer of epoxy. Allow to fully cure before sanding.
- Pour one coat of primer on top of cured epoxy, then apply another coat of primer followed by an additional coat or more depending on your preference. Let dry completely before sanding smooth with fine-grit paper like 400-600 grit wet/dry sandpaper
How long should you wait between coats of epoxy?
You should wait at least 24 hours between coats; this allows the previous layer to cure properly. If you are using a high-density filler, you should wait at least 48 hours between coats.
If you are using a low-density filler or no filler at all, then you should wait 72 hours between each coat.
Can you layer epoxy resin?
Yes, you can layer epoxy resin.
You can layer epoxy resin to make a thicker epoxy or to make a more durable epoxy. This is because adding layers of additional epoxies on top of each other will add strength and durability to your finished product.
It is also possible to use multiple types of resins at once in order to create unique textures and finishes, like glitter or marble patterns.
These are the most common questions about the use of epoxy and resins. If you ever have any more questions about how to get started, or just need some tips on what to do when things go wrong, we’d love to help!
As always, be sure to follow all safety precautions before handling any caustic chemicals.
