Acrylic Medium Showdown! (Which One is Best??)

Hey guys! So in this video I put various acrylic mediums head to head to see which ones do the best job of extending your working time with the paint!
I’ve got acrylic paint by itself, misted with water, and mixed with Self-Leveling Clear Gel, Glazing Medium,Retarder, and Golden’s OPEN acrylic medium.

Which one do you think will win?? Let’s find out which one gives us the longest painting time!

So were you surprised by the outcome? I was a little, bit, but it makes total sense.  So I hope this was as helpful to you as it was a learning experience to me!

Thanks for watching, and be sure to subscribe if you’re new, and thumbs up this video, thank you!!

    Ashley I just purchased Liquitex Slow-Dri Blending Medium. Is that the medium I see you spred over your canvas before you begin painting. Also say I work on painting the next day should I use it again?

      The Liquitex Slow-Dri Blending Medium is Liquitex’s version of Golden’s Glazing Medium, which is what I use in 95% of my acrylic paintings. And yes, it’s usually the glazing medium that I put on my canvas before laying down paint whenever I’m doing something that requires a lot of blending and I need my paint to stay wet and blendable. Paint until you’re happy with the blending, because it will most likely dry completely overnight. So the next day when you come back, if you want to glaze over it or add more colour layers while letting what you painted yesterday shine through, you can lay down another layer of the medium and paint over that, or if you want to start a new layer overtop you can just go right in with straight paint or paint mixed with some other medium, whatever you wish.
      Don’t use too much of the blending/glazing medium on the canvas, as it can make it really slick and paint straight from the tube won’t grab onto the canvas. You can put a bit of medium on the canvas and then mix some medium into the paint so they’re the same consistency, then they will spread into one another instead of slipping overtop. I hope this helps! It’s best just to experiment and see what works best for you, but hopefully this gives you some ideas!

Thanks.

          Haha, have fun opening that package when it gets to you! I’m always excited whenever an order comes to my door, even if I know what’s in it!

    I have to say I’m shocked. I never get anywhere near that time to work my acrylics (golden heavy body) even using retarder or glazing medium, and I am not doing very thin applications either. I once did a similar test with a thin application and I only got 5-6 minutes with retarder added before it was completely dry. So I am wondering why you get such extended times? Is your surface you used hard? Even then, I use a glass palette and my paints, in think piles even with glazing medium added won’t last 30 minutes.
    Hmmm. May need to experiment some more, but experience for me is I have 10 – 20 minutes at MOST regardless of what I use (have not used open medium though).

      Do you live in an arid climate? It’s pretty humid around where I live, so that will slow my paint’s drying time. In the video I applied the paints to watercolour paper. You use a glass palette to hold your paints while painting? You might want to look into an acrylic stay-wet palette, it’s what I use when I want my paints to stay wet because I know I’ll be using them throughout the painting. Anything else I just use paper plates, but the paint dries on them in around 10-15 min. I love my stay-wet palette, the paint sits on a special piece of paper that sits on a wet sponge, so there is lots and lots of humidity around the paint. It also comes with a plastic lid that seals the palette tight, and you can stick the whole thing in the fridge if you’re really worried about the paint drying. Just an idea. I can’t live without mine!

What do you think??
