Epoxy is a great way to seal and protect your concrete surface. It can be used to fix cracks or to create a smooth, shiny finish.
However, if you want to epoxy over epoxy without sanding, you need to make sure that the two coats are compatible.
In this blog post, we will discuss the process of epoxying over epoxy and whether or not it is a good idea. We will also provide some tips on how to get the best results!
Will epoxy stick to epoxy?
Epoxy will not stick to epoxy if you are looking for a permanent bond. If you are just looking for a temporary fix, then it will work.
However, the two epoxies may not have the same finish once they are dry. It is best to test this out on a small area before committing to the entire project.
You may also need to sand down one or both of the surfaces before applying the epoxy so that it has something to stick to.
Make sure that you allow enough time for the epoxy to dry completely before testing the bond or using the surface. impatience can ruin your project!

Do I have to sand before second coat of epoxy?
Generally speaking, you don’t have to sand before the second coat of epoxy. However, if the first coat is particularly rough or uneven, it might be necessary to do a little bit of light sanding before applying the second coat.
Just make sure that the surface is completely dry before applying the new layer of epoxy.
Epoxy cures by reacting with oxygen in the air, so giving it plenty of time to cure is always important.
If you’re not sure whether or not your project needs sanding, it’s always best to err on the side of caution and do a little bit of prep work before applying your finish.
Does epoxy need to be sanded?
Epoxy can be applied over epoxy without sanding; however, it is always best to check with the manufacturer of the products you are using.
Some epoxies may need to be sanded in order to achieve maximum adhesion and durability.
Always follow the instructions on the product labels to ensure optimal results.
How do you pour epoxy over epoxy?
Epoxy can be poured over another epoxy without any additional sanding, provided the two surfaces are completely dry.
Be sure to mix the two epoxies thoroughly before pouring so that you achieve a consistent color and texture.
Pour the epoxy slowly and carefully, taking care not to drip it on your work surface.
If necessary, use a brush or spatula to spread the epoxy evenly.
Let the epoxy cure for 24 hours before using or handling your project.
What happens if you don’t sand between coats of epoxy?
Well, if you don’t sand between coats of epoxy, you might experience some problems with the finished product.
The first issue is that the two coats of epoxy might not adhere to each other very well.
This could lead to peeling or chipping of the finish over time. Additionally, if you don’t sand between coats, you might end up with a surface that’s not very smooth.
This can make the finish look uneven or rough. So, if you’re looking for a smooth, polished finish, be sure to sand between coats!
How do you make epoxy smooth?
Epoxy can be a great way to seal and protect a surface, but it can be tricky to get a smooth finish.
If you’re not happy with the appearance of your epoxy coating, you may be tempted to sand it down and start over.
How long does epoxy need to dry between coats?
Epoxy needs to dry completely between coats. This can take 12-24 hours, depending on the weather and humidity.
You don’t want to apply the next coat of epoxy before the first coat is fully dry, or you’ll end up with bubbles in your finish.
If you’re in a hurry, you can use a hair dryer to speed up the process. Just be careful not to overheat the epoxy or you could damage it.
Once the epoxy has dried, you can start sanding it down if needed. Be sure to use very fine grit sandpaper (220 or higher) so you don’t damage the surface of the epoxy.
If everything looks good, you’re ready for your final coat!
Why is my epoxy bumpy?
Epoxy coatings are often bumpy because they are not completely smooth. This can be caused by a number of factors, such as the application method, the type of epoxy resin used, or the surface texture of the substrate.
In some cases, you may be able to get a smooth finish by sanding the epoxy coating; however, if you don’t want to sand and you don’t mind a slightly bumpy finish, you can simply apply another coat of epoxy over the existing coating.
The new coat will help to hide any bumps or imperfections in the original coat. Just make sure that the coats are fully dry before applying additional coats.
How do you get bubbles out of cured epoxy?
Bubbles can often form in epoxy resin when it is curing. This is caused by a number of factors, such as the type of epoxy resin being used, the ambient temperature and humidity, and the way in which the epoxy is mixed.
If bubbles form in your cured epoxy surface, there are a few ways to remove them.
Why is my epoxy cloudy after sanding?
Epoxy can be cloudy after sanding because the solvents in the epoxy have been removed. When the solvents are removed, the epoxy will become cloudy. You can avoid this by using a slower curing epoxy.
If you are using a faster curing epoxy, you can avoid this by adding a surfactant to the mix.
A surfactant will help keep the solvents in the epoxy and prevent it from becoming cloudy.
You can also avoid this by sanding with very fine grit sandpaper. This will help remove any excess resin that may cause the epoxy to become cloudy.
How do you get epoxy clear after sanding?
If you are looking for a shiny surface, then you will need to sand the epoxy. However, if you are just looking for a smooth surface, then you can skip the sanding step.
Make sure that the surfaces are clean and dry before you start epoxying. If there is any dust or dirt on the surface, it will show up in the finished product.
Also, make sure that the two surfaces are well-adhered to each other before starting.
Applying epoxy over epoxy without sanding is not recommended, as it may not adhere properly and could end up being messy.
If you do choose to go this route, be prepared for some possible problems with the finished product.
How do you finish epoxy resin after sanding?
I’m not sure if you can epoxy over epoxy without sanding, but I think it would depend on the type of epoxy resin you are using.
If you are using a two-part system like West System, then you will need to sand between coats in order to achieve a smooth finish.
If you are using something like Minwax Epoxy Floor Finish, then I don’t think you will need to sand between coats since it is a one-party system.
