You have seen epoxy and know it as a coating. It is used in many different ways, including coatings for floors. You may wonder if it can be used as a primer or sealant for the surface you want to coat.
Yes, epoxy can be used as a sealer and primer, but only if you use an epoxy primer and an epoxy sealer. They are different products with very specific uses.
It is not unusual to get advice from people who tell you that they have done something using a product that was not really suited for the task at hand.
This happens all the time when it comes to painting projects. This is why there are so many paint companies out there making money off of this problem!
Can I use epoxy primer as a sealer?
One helpful aspect of epoxy primer is that it can be used as a sealer. Although many hobbyists don’t realize this, its ability to stick tenaciously to the metal surface ensures that it will also keep moisture from creeping into the bare metal.
Epoxy primer is highly recommended for use on new cars and other automotive projects where you want a layer of protection in addition to the sealer’s abilities.
You can use epoxy primer as a sealer provided that you have stripped all coatings, dirt, grease and rust off the surface first.
Apply several thin coats of epoxy primer to get good coverage and make sure it dries thoroughly before applying more coats or moving on to another step in your paint job process.
This can take up to 24 hours depending on temperature and humidity levels so make sure you take this into consideration when planning your project schedule.
Is epoxy primer the same as sealer?
You may be wondering, is epoxy primer the same as sealer?
The answer is no, they are not the same thing. Epoxy primer and sealer are different products with different uses, application methods, and compositions.
Sealers are applied after a coat of primer has dried and it will keep your metal from rusting.
Can you use epoxy to seal concrete?
Unfortunately, epoxy primer will not work adequately as a sealer for concrete.
Although epoxy primer is a good sealer in general, acrylic sealer works much better on concrete because it is more porous than other surfaces. Concrete has many tiny holes that need to be filled in with proper sealing products like acrylic sealer in order to prevent water and other damaging materials from penetrating the surface of your flooring.
Because of the way it is made, epoxy primer can fill some of these tiny cracks while also providing added protection against chemicals and wear-and-tear on your floor. However, an acrylic sealer is still needed to ensure your concrete’s longevity as a surface material.
If you are trying to find the right product for sealing wood, choosing an epoxy product may be a good idea because it provides more protection against moisture than an acrylic coating would offer. When dealing with wood flooring or furniture pieces this could be very beneficial.
However, if you are working with concrete or another stone surface, you will want to select an acrylic sealer instead of using epoxy as a solution for sealing your floors.
Can I seal wood with epoxy?
Epoxy is a polymer substance used to coat and seal wood. Epoxy is an excellent choice of material to use as a sealer because it can be easily applied to surfaces, provides a hard and durable amount of protection, and produces a shiny finish.
It’s important to differentiate between epoxy, primer, sealer, base coat, and top coat when you’re trying to determine how best to protect your wood flooring or furniture.
A primer helps paint adhere more effectively; a basecoat is what goes on first before the topcoat.
Whenever you’re not quite sure about which product you should be using for your particular purposes, talk with one of the experts at your local home improvement store about sealing wood with epoxy. They’ll help you make all the right choices!
Can you use epoxy primer as a top coat?
You can use epoxy primer as a topcoat, but that is not ideal. The epoxy primer might be too glossy and high build to work well as a topcoat.
You should try to use the proper products for each task. Epoxy primers are designed to have good adhesion properties and resist corrosion.
A high-build product like an epoxy will also help to fill small imperfections in the metal, whereas a top coat is designed more for aesthetics, color retention, and gloss retention than anything else.
Since you’re asking about powder coating, do you know that powder coating does not require any kind of primer? Powder coatings contain all of the same components (primer, sealer, and clear) in one product.
Can I paint base coat over epoxy primer?
You can paint base coat over epoxy primer. However, it’s important to understand that base coat and epoxy primer are two different things.
Base coat is the color-bearing layer, whereas primer is a sealer. The first step in painting a car will be to apply an epoxy primer and let it harden. Then you’ll apply basecoat and clearcoat and let them dry.
It’s best to start from scratch with sandpaper if you think the sealer isn’t secure enough, or if there’s any chance of contamination from dust or other solvents.
Either way, as long as all components are dry, you have nothing to worry about when applying your basecoat over your prepped epoxy primer surface.
Do I need to seal concrete before epoxy?
You can seal concrete before epoxy but it depends on what epoxy you are using.
There are two standard types of epoxy coatings: 100% solid and solvent-based.
100% solid epoxies don’t need to be sealed before application. On the other hand, solvent based epoxies will require the concrete to be sealed in order to prevent moisture from getting trapped in the concrete which can cause blistering.
You typically only have to seal your floor if you are applying a solvent based epoxy coating, and some people choose not to because it can add an extra day or two to their project timeline.
Is primer and sealer the same thing?
So, are primer and sealer the same thing? No, they’re not. Primer is applied before the top coat. Sealer is applied after the top coat to protect it.
How do you know when sealer is required? The manufacturer of your top coat will specify whether you need to use sealer or not. If so, then follow their directions for applying it.
The answer to this question is both yes and no. Yes, an epoxy primer is a sealer, but a sealer is not always an epoxy primer.
It depends on the type of sealer you have. If you have solvent based paint or urethane or lacquer, then using an epoxy primer will allow you to restore the original thickness of paint that was removed when sanding.
