Shelf Life of GOLDEN Acrylics

  1. We are so glad you like the article! Thank you. The only caps that are shown are the lids for the jars of Heavy Body paints and the older flip cap for the Fluid Acrylics. Unfortunately, that cap would not fit on a tube.

  2. I’m wondering if you can give us an article like this on the best way to look after tubes of acrylic paint please. I use my paints almost every day all through the year. It isnt easy to keep the metal screw area clear of paint and so can this also be covered with that thin plumbers tape? Perhaps you have other helpful ideas?
    Also I have one tube of paint that has thickened and I am wondering why? Clearly you couldnt add anything to the tube to thin this. If I manage to squeeze some out and then mix in some medium it tends to look a little grainy and takes quite some mixing to get to a smooth even look.
    Some of these things would be great to learn about
    Thank you in anticipation.

    • I always take a q tip with some Vaseline & wipe
      it around the metal screw area & that works quite well!!
      Excellent with gesso bottles or jars as well!

  3. We know it can be difficult to be concerned with keeping the threads of the tubes clear while in the midst of painting, but if you tried to make sure to wipe the threads right after squeezing the paint from the tube and from the inside of the cap, the cap will be easier to replace and make a tighter seal. The teflon tape should help to make a tighter seal if your threads already have dried paint that you cannot remove. If the seal is not tight, the paint may start to thicken from slowly drying out. You could consider transferring the paint from the tube into an airtight container if this starts to happen and adding a little GAC 100 very slowly and some distilled water could soften it back up. The key is not to add the medium or water all at once, but to very slowly add drops until you get the consistency you are looking for. If you add too much at once, it could feel clumpy and take a longer time to mix smooth. If you use larger quantities of paint, you might consider buying the paint in jars instead of tubes, which may be easier for you. If you would like to discuss further or have any other questions, please feel free to contact us at help@goldenpaints.com.

  4. It is also possible to contaminate the paint with a brush if you are putting it directly into the container of paint. I have also heard that using vasoline on the threads can help keep them clear, but I don’t know what that does to the seal and I suspect you would need to take caution about getting it in the paint.

  5. Putting petroleum jelly on the threads makes us nervous, as it could cause adhesion failure of the paint if it was accidentally applied to a painting or under a painted layer. This failure could occur even with a very thin layer.

  6. I’ve been painting with Golden for over fifteen years. I have never had a problem with it drying out. Colors I use less of I buy in smaller containers. I love this paint!

  7. Thanks for the info! One of the few acrylic tubes that have hardened on me was Mars Black from a competitor. This went almost completely solid. A quart bottle of Titanium White from another competitor was recently emptied some 40 years after purchase. I have had no issues with Golden products since becoming acquainted with them about five years ago.

  8. Someday someone will invent a far better paint tube/ cap the threads on paint tubes are maddening whether oil or acrylic paint always gets on the threads there need to be a new type of capping system
    It is long overdue.

    • I agree! There are “lesser” brands with caps that seem to stay on. I was recently at an art workshop where we used only Golden and a common complaint was the darned caps.

    • Hi Cheryl,

      We think the theory is that if the product is flush against the top of the lid because it is upside down, then it would be more difficult for air to get into the jar. If the lid is clean and on tightly and the product is in a good environment, whether it is stored right side up or upside down, the paint really should remain usable for many, many years.

  10. Thank you for this very useful article. You mention polyethylene plastic sheeting to help reduce “head space” in jars. Could this be done with polyester or polypropylene sheets as well or is there specific chemical properties that make the polyethylene the best choice?

    Reply
    • We recommend polyethylene plastic because the acrylics will not adhere permanently. Polypropylene may also work, as acrylics have poor adhesion to that plastic as well. Acrylics could adhere permanently to polyester, so likely would not be a good choice here. We hope this is helpful.

  11. I have Golden paints kicking around from well over 15 years ago, still as good as new. I think I have your first run of fluid acrylics, actually. They are seemingly immortal as long as you keep good hygiene and don’t let bacteria into the pots.

    • Hi James,

      That’s great to hear and great advice. The acrylic paints contain biocides as a preservative, but sometimes if tap water gets introduced into the paint, mold can grow. If you are storing water thinned paint, we would recommend thinning with distilled water.

  12. Great article. BTW…I just recently started painting but had about 2 dozen tubes of paints from another brand from 35 years ago. Some opened, some not. They were perfectly good. The tubes were plastic. So the shelf life is long.

    But I also started using Golden paints and love them so much better, so it looks like the 35 year old paints will probably sit for another 35 years…lol.

  13. Thanks for this info. I usually place plastic wrap on the tube or jar and then replace the cap. It really helps to make the lids easier to take on and off. But using teflon tape seems like an easier solution. BTW, this may be a silly question, but can I get the polyethylene sheeting at a hardware store?

    Reply
    • Hi Dolores,

      You can get the polyethylene sheeting at a hardware store or home center. It is usually just called “plastic sheeting” and can be found in the building materials department. Is is the same material used for paint drop cloths, but in a thicker gauge and is usually used as a vapor barrier when building walls.

      Best,
      Stacy

  14. Stacey, I’ve found that a drop of glycerin inside the lid helps get a tight fit, cuts through buildup, and helps keep it clean. I also use just a touch of glycerin on my brushes after a thorough cleaning for conditioning. The trick is to use just a tiny amount.

    Reply
    • Hi Barbara,

      Glycerin is a non-volatile humectant, which means it does not evaporate. If mixed with the paint, it could lead to permanently moisture sensitive or sticky films. We would recommend washing brushes before use if conditioned with Glycerin and to take care to limit the amount on threads.

      We hope this is helpful and if you should have any further questions, feel free to email us at help@goldenpaints.com.

  15. I’ve had a collection of Golden brand paints in the 4 oz. tubes, probably a dozen of them, since I took art classes in college back in 2005. I recently pulled these back out of the closet to see if they were still usable, and much to my surprise they still are! and work perfectly.

  16. What’s your opinion on dropping glass marbles into a jar to reduce headspace? I imagine once the jar is completely full of marbles it would be hard to access the paint that’s all in between them but maybe that last bit of paint could then be poured into a small container. I was advised this is something woodworkers would sometimes do with polyurethane. I only have tubes right now anyway but may have jars eventually.

    • We agree that it would be hard to access the paint and would be very messy. Putting a circle of polyethylene plastic down on top of the paint would likely be a lot easier.
