Epoxy resin is used to bond various materials together. Some of these materials include wood, metal, concrete, and glass.
The epoxy resin can be applied in a variety of ways such as brushing or spraying. When applying epoxy over paint, it helps to understand how the paint works so that you can determine if it will react well with the epoxy.
If not, then you may have to sand down the area before applying your epoxy. In this article, we will discuss whether or not you can use epoxy over painted surfaces and what kind of paints are best suited for this application method.
Does epoxy stick to paint?
Epoxy resin is a two-part plastic system that hardens when the two parts are mixed together. This means that it’s not painting, and it doesn’t stick to paint.
However, epoxy will stick to bare wood or metal if you apply it in a thin layer with a brush or roller. You could also use an epoxy adhesive like contact cement to glue down your new surface before applying the fresh coat of epoxy over top of it.

What kind of paint can you epoxy over?
You can use epoxy over any type of paint. There are a few things to consider when deciding which paint you want to use, though.
- Whether or not the paint is compatible with epoxy.
Epoxy doesn’t adhere very well to certain types of paints. If the surface has been painted with oil-based paints or enamel, for example, you’ll probably want to use something else as your base coat so that your topcoat can stick better and last longer than it would if you used those types of paints first.
- How much preparation needs to be done before applying epoxy over other surfaces such as walls and floors?
If you’re preparing an entire room or wall for painting I would recommend using a priming coat first then going over this layer again with one final primer coat before starting on your main color coats (this prevents any bleed-through between layers). This may sound like a lot but it makes all the difference when finished!
Can you use epoxy resin on painted surfaces?
The resin will stick to the paint, but it won’t adhere as strongly as it would to bare wood. If you’re using a brush, this could be an issue—the resin may peel off with little effort.
However, if you spray your surface with the epoxy instead of brushing it on, the adhesion should be stronger and less likely to come off with movement or time.
Can I epoxy over old paint?
In order to epoxy over old paint, the following conditions must be met:
- The paint must be dry. If you think it’s been too long or it’s been raining all week, check on it.
- The paint must be in good condition. If there are small peeling spots or cracks on the surface of the wall, then no—you can’t just lay down some epoxy over those areas and call it good enough. It’ll just look bad when you start sanding those areas down later on.
- The paint must be oil-based (for example, latex paints don’t work with epoxies).
- Finally, if your walls are painted with flat finishes rather than high glosses then that’s fine too!
Can you pour epoxy over acrylic paint?
No. You can’t just pour epoxy over acrylic paint. Epoxy is a polymer that is made from two chemicals that bond together when mixed or cured and then harden into a solid material. Acrylics are polymers too! So why won’t it stick?
Since both epoxies and acrylics are polymers, they’ll have similar characteristics and chemical makeups under certain circumstances (which we’ll cover later).
They both have the same basic structure: long chains of monomers that form cross-linking bonds between them as they reach their full cure state.
However, because epoxies are designed to be stronger materials with better adhesion than acrylics, you shouldn’t expect them to bond with each other or even stick together when used incorrectly—even if they come out of the same bottle!
Can you pour epoxy over oil based paint?
Oil-based paints are notorious for being a pain to remove. In fact, if you have an oil base paint job, it’s likely that the paint is flaking off in spots and peeling away from the surface of your car or wall.
If this is the case and you’d like to use epoxy as an alternative to repainting, then there are ways to get it done.
First things first: Prepare for success! Make sure that you have all of the necessary tools on hand before starting your project – everything from a solvent (such as mineral spirits), paint stripper, heat gun, and so forth should be easy to find at any hardware store or home improvement center near you.
You’ll also want some form of sandpaper so that when applying epoxy over bare surfaces they will bond properly with no gaps between them – this can be done by either hand sanding or using power tools like grinders/rotary tools which work great too but may require protective gear depending on how much ventilation there is around where they’re running because these types of machines tend to generate lots dust particles while operating at high RPMs (rotations per minute).
How do you apply epoxy to painted wood?
If the wood is in good shape, you can apply an epoxy coating on top of it without stripping the previous paint. The first step is to clean and sand the wood.
You’ll want to make sure there are no oils or dirt left on the surface before applying your coat of epoxy. Once you apply a thin coat of epoxy over your cleaned surface, let it cure for about 24 hours before applying another thin layer (this will be much easier if you use a quality brush).
Then let that coat cure for another 24 hours and sand down with 80 grit sandpaper in order to smooth out any bumps or ridges from your first two coats of epoxy.
After sanding, apply one more thin layer of epoxy over your entire project (be sure not to get any on windowsills or doors) and let it set up overnight.
Can you put epoxy over enamel paint?
Enamel paint is a type of paint that can be applied in a layer. It’s not the same as regular paint and isn’t a good choice for epoxy because it’s not porous.
Enamels are made up of various ingredients, including pigments, binders, and solvents. The binder holds the pigment together and gives enamel its shine or luster.
Enamels are typically cured with heat (but not too much heat), unlike the other types of paints we’ve talked about so far like acrylics, oils, and watercolors which use different curing methods to set their colors onto your canvas or paper surface (more on this below).
