Some people who are looking to refinish their floors might wonder if polyurethane adheres to epoxy resin.
The answer is yes, but the process can be difficult. Epoxy resins are strong and durable, but they also have a high level of sheen that some people don’t like.
Polyurethane is known for giving a dry-to-the-touch finish with low sheen levels so it’s possible to create an appealing floor by combining these two products together.
However, there are several pitfalls that you need to know about before starting this project on your own!
How Do You Apply Polyurethane To Epoxy?
Epoxy resin is a strong, durable material that can hold up to heavy wear and tear.
It also has a high sheen level which some people don’t like because it reflects light off the floor in certain ways.
Polyurethane on the other hand provides an easy-to-maintain finish with low levels of sheen so you might be interested in combining these two materials together!

Will Oil Based Polyurethane Stick To Epoxy Resin?
No, polyurethane doesn’t adhere to epoxy resin and the opposite is also true. Different types of polyurethanes work best on different surfaces so make sure you’re using the right one for your flooring!
Nonetheless, it’s possible (though difficult) to apply a layer of polyurethane over an existing coat of epoxy resin in order to add protection or change the finish level.
It can be done with some persistence but there are no guarantees that this will produce high-quality results every time.
This is because applying one product over another requires careful attention during application as well as making sure that materials don’t react adversely if they get mixed together at any point during installation.
Can You Put A Clear Coat Over Epoxy?
Yes, it’s possible to put a clear coat over epoxy resin but there are some caveats. If the polyurethane is applied too heavy or with uneven coverage then bubbles may form in the finish and cause problems later on down the line.
Moreover, if you apply an additional layer of polyurethane without removing all traces of what was previously used beforehand (epoxy) then this will affect how well that second application adheres often leading to bubbling as mentioned above!
Will Water Based Polyurethane Adhere To Epoxy?
No, water-based polyurethane will not adhere to epoxy resin. It can be applied over an existing coat of epoxy though with some persistence but there are no guarantees that this process won’t produce anything less than high-quality results!
The reason for this is because applying one product over another requires careful attention during application as well as making sure that materials don’t react adversely if they get mixed together at any point during installation.
What Is Stronger Epoxy Or Polyurethane?
The answer to this question depends on the type of polyurethane you’re using. Oil-based polyurethane is stronger than water-based, for example, so it can be used in more applications while still providing a comparable level of protection.
How Do You Apply A Clear Coat Over Epoxy?
It’s possible to apply a clear coat over epoxy resin, but there are some caveats. If the polyurethane is applied too heavy or with uneven coverage then bubbles may form in the finish and cause problems later on down the line.
Can You Put Varnish Over Resin?
Yes, it’s possible to put varnish over resin. However, the process is not straightforward and there are some things you should know before attempting this on your own!
What type of flooring do you have?
Is the surface uneven or damaged in any way?
Is the coating new (or at least newer) than what was previously applied on top of it? If so then has a layer been sanded off already? What about previous coatings were they oil-based or water-based polyurethane products like an acrylic sealer for example? All these variables will affect how well different coats adhere to each other as well as which types of materials can be used together without reacting adversely with each other.
Do you want a glossy or low-sheen finish? Where are you applying the varnish – on top of the wood, over epoxy resin, etc.?
All these variables will affect how well different coats adhere to each other as well as which types of materials can be used together without reacting adversely with each other!
So for example, if your flooring is an old wax seal and then someone later tried using oil polyurethane and now there are bubbles forming in the surface due to improper application methods then that would necessitate sanding off the previous layer before continuing (or starting from scratch).
Can You Seal Wood With Polyurethane Before Epoxy?
Yes, but it is not recommended. Applying multiple coats of polyurethane coatings over a single layer will result in the topcoat becoming much less effective and so this should be avoided at all costs!
Best Polyurethane Topcoat Over Epoxy?
The best polyurethane topcoat for epoxy would be the one that can provide both a shiny and low-sheen finish.
Oil-based polyurethanes are often considered to be stronger than water-based ones, so this might make them a more ideal candidate when you want something with high durability!
However, these types of coatings also have their drawbacks too they take longer to dry and require thicker coats in order to work well without leaving streaks or unsightly bubbles behind which is why many people prefer using acrylic sealers instead.
These give off fewer fumes during application as well, making them better suited for use indoors where there are typically higher air quality standards!
