The short answer is yes. Epoxy can be used to create a strong bond between the powder-coated surfaces.
Powder coating is a great way to add more protection to your items.
It’s a good alternative to painting that gives your items more strength.
It can protect your items from the elements and corrosion. However, it can also look very nice as well.
If you’re planning on powder coating the tumbler, it’s a great idea to epoxy over the powder.
This will make them look even nicer and also protect the powder coating.
Can you paint over the powder coating?
Powder coating is a type of coating that is applied as a dry powder and then cured under heat. It is typically used to create a hard, durable finish on metal surfaces.
Epoxy is a type of resin that is used as an adhesive or sealant. It is typically used to create a strong bond between two surfaces.
However, it is important to note that the bond may not be as strong as the powder coating itself.
Does epoxy stick to the powder coat?
Powder coating is a great product to protect manufactured parts. And epoxy is a great product to seal and bond to just about anything.
However, epoxy and powder coating can be a recipe for disaster, if you don’t do it right. Here’s why. Epoxy will not stick to the powder coat and the powder coat will not stick to epoxy.
That’s because the powder coat is not porous. The powder coat must be sanded down and roughed up or etched before epoxy can stick to it.
Epoxy and powder coats work best when they do not touch each other. Epoxy should be applied to bare metal, then powder coat
can be applied over epoxy.
However, you may still be able to use it if you “burnish” (kind of like sanding) it, depending on the epoxy.
I have had great luck with the 3M 820 epoxy. The only issue that I had was that I was tacking it down to the concrete and I didn’t rough it up enough.
I just made sure to rough it up better and reseal it with more epoxy before applying the powder coat.
How do you prepare powder-coated tumblers?
Powder coating is created by spraying a liquid polymer, usually a polyester or epoxy resin, with fine metallic particles on the surface, then curing it with the heat of an oven.
1. Fill your powder-coated tumbler with 6 cups of water.
2. Add one packet of powder and mix it with water.
3. Fill the tumbler to the brim with lukewarm water.
4. Seal the lid and let it sit overnight.
5. Rinse the tumbler well and drain it.
6. Fill it with 6 cups of water and let it sit overnight.
7. Rinse the tumbler well and drain it.
8. Fill it with 6 cups of water and let it sit overnight.
9. Rinse the tumbler again, then dry it.
10. Fill it to the brim with lukewarm water and let it sit again overnight.
11. Rinse the tumbler well, then drain it.
12. Fill it to the brim with lukewarm water, close the lid and shake it well for about 20 minutes.
13. Drain the water and let the powder-coated tumbler sit for about 2 hours.
14. Rinse it well and dry it with a soft cloth.
15. Add water and shake it again for about 20 minutes.
16. Repeat the process of adding water, shaking, and draining the tumbler until the water no longer becomes cloudy.
17. Wash the powder-coated tumbler with dish soap and let it sit overnight. 18. Rinse the tumbler well and let it air dry.
How do you remove the powder coat from tumblers?
There are a few different ways that you can remove powder coat from tumblers. One way is to use a chemical stripper. This will require you to purchase a chemical stripper specifically designed for removing the powder coat. Follow the instructions on the stripper carefully, as you will need to apply it to the tumbler and let it sit for a period of time before wiping it off.
Another way to remove the powder coat from tumblers is to sand it off. This will require you to use high-grit sandpaper and sand the tumbler until the powder coat is removed. This method is more time-consuming, but it is also less expensive than using a chemical stripper.
Once you have removed the powder coat from the tumbler, you will need to clean it thoroughly before applying a new coat of powder. You can do this by wiping it down with a clean cloth and some rubbing alcohol.
What kind of paint will stick to powder coating?
Epoxy will stick!
Powder coating is a type of paint that is applied as a dry powder and then cured under heat to form a hard, durable finish. Powder coating can be applied to a variety of surfaces, including metal, plastic, and glass.
Most powder coatings are made from polyester or epoxy resin, and they are available in a wide range of colors. When choosing a paint for powder coating, it is important to select one that is compatible with the powder-coating resin.
Some paints may not adhere properly to the powder coating or may not cure correctly, which can lead to poor durability and performance.
Can you epoxy a colored tumbler?
Yes, you can epoxy a colored tumbler. The process is fairly simple and doesn’t require any special tools or materials.
- First, clean the tumbler thoroughly with soapy water and let it dry completely.
- Next, sand the surface of the tumbler to rough it up a bit and help the epoxy adhere better.
- Then, mix the epoxy according to the manufacturer’s instructions and apply it to the tumbler, being sure to evenly coat the entire surface.
- Finally, let the epoxy cure for the recommended amount of time before using the tumbler.
My verdict
You will need to perform a test at a hidden area of the tumbler to see if the epoxy will affect the powder coat.
There are some epoxies that have a very strong solvent that can dissolve the paint on the tumbler.
If you have any doubts, you should buy a small tumbler at the hardware store and perform a test.
- Add the epoxy to the tumbler and allow it to sit for a period of time. If the epoxy begins to dissolve the powder coat, then you should use a cup of sanding block to sand the epoxy off.
- After the epoxy is removed, use a degreaser to remove any remaining epoxy or powder coat.
- Allow the tumbler to dry completely before applying a new coat of epoxy.
FAQs
No, you cannot! What I mean by this is, that you cannot technically paint directly over powder coating since paints don’t stick to powder surfaces. But you can though, prepare the surface and use epoxy.
Yes, you can. Make sure to have a clear coat before though.
They are not the same, but in technicality, if you are thinking of the function they serve. They do the same thing: protect your cup, tumbler, or the surface you wanted them on. But epoxy does it better, and lasts longer. With a bit of preparation and correct application, it will also stick to almost all sorts of surfaces.
