Epoxy and polyurethane are both clear finishes that can be applied to wood floors, but they serve different purposes. Epoxy is a hard, durable finish that is typically used in high-traffic areas, while polyurethane is a softer finish that is more resistant to scratches and moisture. You can apply polyurethane over epoxy, but it is not recommended because the two finishes will not adhere well to each other.
Can You Put Polyurethane on Epoxy?
Yes, you can. But there are a few different types of polyurethane, and each has different properties. The two most common types are oil-based polyurethane and water-based polyurethane. Oil-based polyurethanes have excellent durability and provide a beautiful finish, but they can be difficult to apply and take longer to cure than water-based polyurethanes.
Water-based polyurethanes are much easier to apply, but they don’t last as long as oil-based finishes. Epoxy is a resin that is used in many different applications. It is frequently used as an adhesive or coating for metal surfaces.
Epoxy is very strong and durable, making it an ideal choice for many industrial uses. However, epoxy can be difficult to work with and it is not always compatible with other materials. Polyurethane can be applied over epoxy, but there are a few things to consider before doing so.
First of all, make sure that the epoxy is fully cured before applying the polyurethane. If the epoxy is not completely cured, it could react with the polyurethane and cause problems. It’s also important to choose the right type of polyurethane for the job.
If you’re looking for durability, go with an oil-based finish. If you need something that’s easy to apply, go with a water-based option.
What Finish Can I Put Over Epoxy?
If you’re looking to add a little extra protection or shine to your epoxy project, there are a few different finishes you can use. One popular option is polyurethane, which can be applied directly over the top of the cured epoxy. You could also try using a clear lacquer or enamel for a similar effect.
If you want something with a bit more sparkle, you could try adding glitter or mica powder to your clear finish of choice. Whatever route you decide to go, just make sure you give your epoxy plenty of time to cure fully before applying any sort of topcoat.
Can You Put Clear Coat Over Epoxy?
It is not recommended to put a clear coat over epoxy. The epoxy will yellow and become brittle over time, and the clear coat will not be able to protect it. If you must put a clear coat over epoxy, make sure to use a urethane-based clear coat that is compatible with the epoxy.
Do I Need to Sand Epoxy before Polyurethane?
No, you do not need to sand epoxy before polyurethane. Epoxy is a tough and durable material that can withstand the rigors of sanding. However, if you want to achieve a smooth, professional finish, it is recommended that you sand the epoxy after it has cured.
Best Polyurethane Top Coat Over Epoxy
If you are looking for the best polyurethane top coat to use over epoxy, there are a few things to consider.
First, what type of finish do you want? There are glossy finishes, semi-gloss finishes, and flat/matte finishes.
Each has its own benefits and drawbacks, so it’s important to choose the one that will work best for your project.
Second, how much durability do you need? If you are using the coating in an area that will see a lot of wear and tear, you’ll need something more durable than if you’re just using it for cosmetic purposes.
Third, what is your budget? Polyurethanes can range in price from fairly inexpensive to quite costly, so it’s important to know how much you’re willing to spend before shopping around. Once you’ve considered all of these factors, it’s time to start shopping!

Adding a polyurethane finish to epoxy countertops
Can You Put Oil Based Polyurethane Over Epoxy?
For many years, the debate has raged on about whether you can put oil based polyurethane over epoxy. Some say that it can be done, while others claim that it is a recipe for disaster. So, which is it?
Can you put oil based polyurethane over epoxy, or not? The answer may surprise you. It turns out that yes, you CAN put oil based polyurethane over epoxy… but there are some things that you need to know first.
Here’s what you need to know about using oil based polyurethane over epoxy:
1. Make sure the epoxy is fully cured before applying the polyurethane. If the epoxy is not fully cured, it can react with polyurethane and cause problems.
2. Apply a test coat of polyurethane to a small area before doing the entire project. This will help you make sure that the two products are compatible and will also give you a chance to see how the finished product will look.
3. When applying the polyurethane, use a brush or roller specifically designed for use with oil-based products.
Do not use a regular paintbrush, as this could damage the finish of your project.
Polyurethane Over Epoxy And Wood
Epoxy and polyurethane are two different types of resin that are often used in woodworking. Epoxy is a synthetic thermosetting plastic that is derived from petroleum products. It is known for its strong bonding properties and resistance to heat and chemicals.
Polyurethane, on the other hand, is a synthetic polymer that is made by reacting a polyol with an isocyanate. It has various applications, one of which is as a clear coat for wood floors. When it comes to choosing between epoxy and polyurethane, there are several factors to consider.
One important factor is the intended use of the resin. For example, if you need a resin that will be exposed to high temperatures or harsh chemicals, then epoxy would be the better choice. On the other hand, if you need a clear coat that will protect your wood floor from scratches and wear-and-tear, then polyurethane would be the better option.
Another factor to consider is working time. Epoxy has a shorter working time than polyurethane, which means that it needs to be mixed and applied more quickly. However, this also means that epoxy has a shorter cure time than polyurethane – meaning that it will reach its full strength faster than polyurethane will.
This can be an advantage if you need your project to be completed quickly. However, it also means that epoxy can be more difficult to work with since it hardens so quickly. Finally, cost may also be a factor in your decision-making process.
In general, epoxy tends to be more expensive than polyurethane due to its longer shelf life and higher level of performance. However, there are some cheaper alternatives available on the market – so it’s definitely worth shopping around before making your final decision!
It is often asked if one can put polyurethane over epoxy. The answer is usually yes, you can do so, but there are a few things to keep in mind. First, make sure that the epoxy has fully cured before attempting to apply the polyurethane.
If it hasn’t been cured completely, the two products may not adhere well to each other and you’ll likely end up with a mess. Second, remember that polyurethane is a topcoat and as such it will not fill in any cracks or imperfections in the underlying surface. So, if your goal is to achieve a smooth, flawless finish, you’ll need to make sure that the surface is prepped accordingly before applying the polyurethane.
Finally, be aware that polyurethane can yellow over time so if you’re looking for a clear finish, keep this in mind when choosing your product. Overall, however, polyurethane is an excellent option for protecting and sealing surfaces treated with epoxy.
