Epoxy is a great way to protect wood, but it won’t stick to old paint. If you want to use epoxy on painted wood, you’ll have to remove the old paint first (which can be a pain).
You can use either an abrasive pad or chemical stripper (depending on what type of paint was used) and then sand off any remaining loose bits before applying your epoxy.
Does epoxy stick to paint?
The answer is yes, but it depends. There are many variables that can affect this, so the first thing you should do is talk to your local paint store and ask them what type of paint best suits your project.
If you’re using epoxy over a painted surface, the type of paint will have an effect on how well the epoxy adheres to it. Some paints have better adhesion properties than others.
For example, oil-based paints tend to be more difficult for epoxy to adhere to than latex-based paints. However, some oils may actually help enhance the bond between epoxy and pained surfaces!
The second factor that comes into play here is whether or not you’re using marine grade or standard types of epoxy resin systems when working with your woodworking project material (primer).
In general terms: if it’s a non-marine grade then try another option like polyester resin instead which has great adhesion properties!
Thirdly: surface preparation matters greatly when bonding two surfaces together through adhesive means such as these two materials together.

What kind of paint can you epoxy over?
The short answer is yes, you can apply epoxy over many different types of paint. Epoxy will stick to any kind of paint that is not oil based.
This means that acrylics, latex, and enamels are all good candidates for epoxy application. Oil-based paints are not a good choice for epoxy because they won’t bond well together and could eventually separate from the surface you’re applying it too if left exposed to moisture like rain or humidity for extended periods of time (you should always make sure to use a primer on these surfaces).
Can I epoxy over old paint?
Yes, you can apply epoxy over old paint. It’s worth noting that the type of surface you are covering will have an effect on how well it works.
For example, epoxy can be applied over gloss and matte paints without any problems. However, when applying epoxy over oil-based paint or water-based paint it is important to sand the existing surface before applying the epoxy sealer.
This ensures a strong bond between the new finish and the existing surface.
Can I epoxy over acrylic paint?
Acrylic paints are not as durable as oil-based paints. Epoxy will not adhere well to acrylic paint, and you should try another product if you have a project that requires both types of products.
It’s possible that the paint may peel or crack after the epoxy is applied over it, especially on vertical surfaces like walls or ceilings.
Acrylic paint also has a tendency to fade in direct sunlight compared with other paints such as alkyd enamels, which means there might be some discoloration occurring around your home once the sun starts shining on your painted surfaces again after applying epoxy.
This could be an issue if you’re planning on spending time outside with family members once spring rolls around! Additionally, acrylics tend not to stain well—in fact, they usually soak into whatever surface they come into contact with instead of adhering directly onto that surface like oil-based paints do (as long as there isn’t any moisture present).
So if someone spills red wine onto their new wooden table top made out of recycled oak planks treated with an oil finish by hand every year – it won’t matter because both types will stain equally badly!
Does epoxy stick to gloss paint?
Epoxy is a high-performance coating, and it can be applied over paint. However, it is not recommended for use on glossy surfaces because the epoxy may peel off in the future. This is because epoxy is a thick coating and may not adhere well to glossy paint.
Instead of using epoxy on top of your current paint, you can apply primer first. Primer will help make sure that the surface underneath your new layer of paint has a smooth surface so that any type of finish product will adhere properly and last longer.
Can you pour epoxy over oil based paint?
Epoxy is a very difficult product to remove from oil-based paint. The epoxy will likely not stick, and it could take multiple attempts to get the two materials to bond well enough that they don’t peel or crack.
You can try pouring the epoxy over the existing paint, but you may want to consider cleaning off all of the old paint first so that there isn’t anything on top of it.
Cleaning off all of this old material may be easier said than done though—some people have reported spending 40 hours removing old oil-based paint before they were able to start working with their new epoxy coating!
If you choose not to clean off all of your old oil based paint first, then you’re looking at possibly having two different types of peeling happening at once: one where your new coatings fail due to underlying layers being too thick (which means more work for you), and another where peeling occurs because the gradients between each layer are too severe (which means more work for everyone).
Can I epoxy over water based paint?
Epoxy is not recommended for use over water based paint. It will not stick to latex or polyurethane (two major types of water-based paints).
It also has trouble adhering to acrylics, though you can get away with using it in some areas if you are careful. If you want to use epoxy on your project, we recommend using an oil-based or varnish as a primer instead.
How do you apply epoxy to painted wood?
To apply epoxy to painted wood, you will first need to clean the surface with a good detergent. Wet down the area where you will be applying the epoxy with water and then apply it in thin coats using a squeegee.
Let each coat dry before applying the next. Make sure there are no excess drips or globs of epoxy on your piece as this can lead to bubbles or runs in your finish.
Once all coats have been applied, sand lightly before painting over them with any type of paint that adheres well to wood surfaces (examples include latex and oil-based paints).
Conclusion
The answer to this question is an unequivocal yes. You can use epoxy over paint and you should use it if you have a project that needs protection from water.
Epoxy is one of the best products for protecting wood in outdoor areas where rain or sun might damage your work.
It also works well on painted surfaces because it has great adhesion and flexibility from being applied on both sides.
