Epoxy is a very popular choice for coating surfaces because it provides a durable and long-lasting finish.
However, if you are pouring epoxy very deeply, you will need to wait between coats in order for it to cure properly.
In this blog post, we will discuss how long you should wait between coats of epoxy, depending on the depth of the pour.
How long between epoxy pours?
If you are pouring epoxy very deep, you should typically wait between coats.
This allows the epoxy to cure properly and prevents air bubbles from forming.
Depending on the depth of your pour, you may need to wait up to 24 hours between coats.
Be sure to consult the instructions on your epoxy for specific curing times.

How long should resin sit before adding another layer?
If you are pouring your epoxy resin very deeply, you will need to wait between coats. The time you should wait depends on the depth of your pour, the temperature, and the humidity.
For example, if you are pouring a shallow layer of epoxy that is less than ¼ inch thick, you may only need to wait an hour or two before adding another coat.
However, if you are pouring a deep layer of epoxy that is more than ½ inch thick, you may need to wait up to 24 hours before adding another coat.
Why is my epoxy bumpy?
There are a few reasons this could be happening. The first reason is that you didn’t wait long enough between coats.
If you are pouring epoxy very deep, you should typically wait 24-48 hours in between coats.
This gives the epoxy time to fully cure and prevents bumps from forming.
Another reason your epoxy might be bumpy is because of the temperature. If it’s too cold, the epoxy will take longer to cure and can form bumps.
Conversely, if it’s too hot, the epoxy will cure too quickly and can also form bumps.
How thick can you pour epoxy at once?
The maximum thickness you can pour epoxy at one time is about ½”. If you are pouring epoxy that is deeper than ½”, you will need to wait for the first coat to cure before adding another coat.
Depending on the depth of your project, this could mean waiting anywhere from 24 to 48 hours between coats.
What happens if you don’t sand between coats of epoxy?
If you don’t sand between coats of epoxy, the second coat will not adhere properly and will eventually peel off.
The first coat must be completely dry before applying the second coat. If you are unsure whether the first coat is dry, you can test it by pressing your finger into the center of the area you coated.
If your fingerprint sinks into the epoxy, it is not yet dry.
What happens if you pour epoxy too thick?
If you pour epoxy that is too thick, it will not cure properly. This can cause the epoxy to remain tacky or soft, and it might not adhere to surfaces as well.
In some cases, pouring epoxy that is too thick can also cause it to yellow or discolor.
How long does it take for resin to thicken?
This is a question we get a lot, and unfortunately, there is no one definitive answer.
The truth is that it depends on a number of factors, including the temperature of your workspace, the type of resin you are using, and how deep you are pouring the resin.
Generally speaking, however, you can expect resin to start thickening within 30 minutes to an hour.
How do you apply a second coat of epoxy?
You will need to wait until the first coat of epoxy has cured before applying a second coat.
The cure time will depend on the temperature and humidity levels in your workspace.
In general, you should wait at least 24 hours before applying a second coat of epoxy.
If you are unsure, it is always better to err on the side of caution and wait longer rather than apply the second coat too soon.
Can you pour epoxy over epoxy?
The short answer is yes, you can pour epoxy over epoxy. However, there are a few things to keep in mind when doing so.
First, you need to make sure that the first layer of epoxy is completely cured before adding another layer on top.
Otherwise, the two layers will not adhere properly and could result in your project coming apart.
Second, if you are pouring multiple layers of epoxy, you will need to wait at least 24 hours between each coat.
This gives the lower layers time to cure and prevents the upper layers from putting too much pressure on the lower ones.
How do you make epoxy smooth?
If you want to make your epoxy smooth, you should wait at least 24 hours between coats.
This will give the epoxy time to cure and harden so that you can sand it down and get a smooth finish.
You can also use a heat gun to speed up the curing process. Just be sure not to overheat the epoxy or it will start to bubble and become unusable.
How do you shine epoxy after sanding?
The next step is to sand the epoxy. You’ll want to use very fine grit sandpaper for this, such as 2000 grit.
Sanding will smooth out any imperfections on the surface and prepare it for polishing.
Once you’ve finished sanding, you’ll need to remove all the dust from the surface before continuing.
The easiest way to do this is with a vacuum cleaner fitted with a soft brush attachment.
What causes fisheyes in epoxy?
Fisheyes are caused by contaminants on the surface that the epoxy is being applied.
The most common contaminant is oil, but other things like wax, grease, and silicone can also cause fisheyes.
If you’re using a solvent-based epoxy, make sure to clean the surface with a degreaser before applying the epoxy.
