Simply put, epoxy is the best primer for bare metal, making it excellent for newly fabricated metal parts or ones that have been fully stripped. 2. Mixed Surfaces — Some primers and coatings need the entire surface to be uniform and all the same material.
What are the advantages of epoxy primer?
Epoxy primers are thin, providing a better adhesion as it penetrated into the concrete substrate allowing a better bond. Primers provide a better chemical bond when using thicker epoxy base coats. This results in a longer lasting and a more durable concrete floor coating.
Which is better epoxy or urethane?
Epoxy vs Urethane Coating Strength Urethane and epoxy are both quite strong, but in slightly different ways. Epoxy is physically stronger, and is more resistant to crushing forces – such as being driven on by heavy vehicles. So epoxy coating is a good choice for spaces which will see a lot of heavy traffic.
What is epoxy primer?
It is an airtight sealer that protects the primer before the walls are ready for paint. It also acts as a binding ingredient between the concrete, and the topcoat of the paint. Epoxy primer paint protects the walls from extreme weather conditions.
When should epoxy primer be used?
Epoxy primer refers to a sealer that has a non-porous finish. It is primarily recommended as the first base coat over bare steel. These base coats or epoxy primers can be used over fiberglass, plastic or the black iron phosphate coating as well.
Can you paint over epoxy primer?
1) recommend waiting 24 hrs before top coating, but depending on temp can be sooner. 2) Up to 7 days after epoxy can topcoat without sanding or scruffing. no additional primer required if the surface is good.
Does epoxy primer need to be sanded?
(Q) Do I have to sand Epoxy Primer before topcoating? (A) No, epoxy may be topcoated without sanding up to four or five days. After that point, you'll need to abrade the surface.
Which is better red oxide or epoxy primer?
Epoxy Primer has better chemical resistance, abrasion resistance and adhesion than Redoxide. Epoxy primer will chalk under UV, thus a topcoat is recommended when used outdoor. Redoxide on the other hand has better UV resistance, easier to apply because it is one part and cost cheaper than Epoxy Primer.
Is epoxy primer necessary?
An epoxy primer is the foundation of your floor coating system. Without it, your epoxy system will not work as well no matter what type of epoxy you are applying. Epoxy primers are the layer that you will build upon with other base coats and topcoats.
How long can epoxy primer sit before painting?
They also hide and prevent rust or corrosion. Most primers should sit on a car for around 24 hours before applying the base coat of paint. Some primers may dry in as little as 30 minutes, but experts say to apply the primer 24 hours before painting for the best results.
Why is epoxy not adhering to concrete?
This is because the epoxy cannot adhere properly to marginally prepared surfaces, resulting in potential floor coating failure.
What is epoxy floor coating?
An epoxy floor coating is a two-part system that results in an extremely hard and durable surface. If your workspace needs to support heavy traffic, an epoxy coating is shock resistant and helps to protect your facility’s floors both from the long-term impacts of heavy floor traffic as well as driving or even dropping heavy loads.
Is urethane flooring better than epoxy?
Abrasion resistant and more color-retentive than epoxy coatings, urethane floor coatings can last longer and look better . This type of flooring is designed to protect against ultra violet light and abrasions. If you have an industrial facility that gets a lot of daily use, this floor coating would be a good choice for you.
Is epoxy good for 5s?
Epoxy is available in a wide variety of colors, making it a good choice for 5S floor striping applications as well as creating attention-grabbing patterns or designs. Additionally, epoxy is amazingly resistant to both water and chemical exposure.
Do you have to remove urethane before installing?
Like epoxy, urethane can adhere to previous finishes, so existing coatings do not always have to be removed prior to installation. Learn more about the benefits of urethane flooring.
Can you use urethane on industrial floors?
If you have an industrial facility that gets a lot of daily use, this floor coating would be a good choice for you. Urethane is also available in a wide array of colors, but can also be applied clear so that existing colors and textures of the floor can show through.

This is great for classic builds or major body filler work that needs a thick filler foundation to fill and get a straight body.
What is etch primer?
Types of products and their uses; Etch primers (some are 2K) “Wash” or “Vinyl wash” are for bare metal applications for the ultimate in adhesion and corrosion protection. They are very low in solids with next to zero filling qualities. Some are even semi transparent. They are usually not to be top coated with paint.
What is the best primer for auto body restoration?
Urethane primer (2K) Urethane primer is the most common primer used in auto body and restoration by far. It has good solids and fills well. It is easy to sand and can provide you with a perfect body when blocked properly. Care should be taken when applying it as to not use too much.
What is the difference between a barrier coat and a wet on wet sealer?
The difference being with “wet on wet” the sealer is applied and then allowed a short flash time before the basecoat or SS is applied. A “barrier coat” is where the sealer is applied, then allowed to cure or at the very least to totally flash.
Does 2K dry out?
It may or may not use a third component in the form of a solvent. 2K products don’t “dry” like a 1K. The 2K product “cures” by molecules linking together to form a whole new compound. Most high quality 2Ks are insoluble after a full cure and will not soften when exposed to solvents like thinners or gas.
Can you use sticky resin on bare metal?
It typically has poor filling and sanding qualities (that sticky resin makes sanding difficult) . It is ideal for use as a “primer/sealer” on bare metal that requires no surfacing. Perfect for frames and components, radiator supports, items that are sandblasted and you only need to prime and paint.
