When it comes to the creation of extraordinary textures or any other cool effects, Acrylic Paint Mediums are indispensable! Adding them to your art routine can help you transform your paints and make them super versatile! I personally love using acrylic paint mediums a lot and recommend everyone to give them a try! 🙂 This is so much fun plus you get to achieve some really interesting results.
So what is Acrylic Paint Medium in a nutshell? This is a liquid, gel, or paste that you mix into your paint. It's made with the same emulsion base as acrylic paint, so they dry at the same rate, that is why the risk of paint cracking is way less compared to oil paint mediums.
It's very hard to classify acrylic mediums because there are so many different ones... besides they vary from brand to brand. But generally, mediums can either thin your paint, thicken it or add some special texture. There is also a surface prep medium - Acrylic Gesso - and a painting finish medium - Varnish, but this is a whole separate topic. I understand that acrylic mediums are often a difficult concept to grasp until you actually dive into them, so I’ve tried to simplify things for you.
Acrylic Paint Mediums Types
Acrylic Gel Medium
Gel Medium is a great multipurpose medium that is mostly used to add body to paint for impasto techniques, so that it retains brushstrokes, as well as extending color volume and adding transparency without compromising the consistency and adhesive properties. This medium is also an excellent adhesive on its own and also enhances the paint durability and is usually available in gloss or matte finish.

Acrylic Modeling Paste
Modeling paste is the most commonly used texture medium. This is an opaque-white heavy paste that is usually made of marble paste and will adhere to most surfaces. Once dried, modeling paste can be sanded and/or painted over. You can literally make your painting three-dimensional by building up a relief. Or you can mix it in the paint before the application for impasto technique. Modeling paste has a slightly rough texture once dry and remains opaque white.
Special Effects Acrylic Paint Mediums
There are numerous mediums that are designed to create special effects and to imitate certain textures. Some of them have additives like sand, glass beads, or fibers. Here are the examples of special effects mediums: Ceramic Stucco Effect, Blended Fibers Effect, Black Lava Effect, Glass Beads Effect, Iridescent Effect, Natural Sand Effect, Resin Sand Effect, String Gel Effect, Opaque Flakes Effect.... and this list is not full, there is yet so much more! You can also create your own texture by mixing in some sand, sawdust, even eggshells, or whatever you want to gel medium or paint.
Gloss or Matte Fluid Acrylic Medium
This medium is designed to thin the paint a bit, add some transparency and correspondingly gloss or matte finish. When do you want to use this medium? For example, when you work with heavy body paints (which are normally opaque and have satin finish) and you want to add some gloss and/or transparency. Or when you need to cover a large surface with an even layer of paint (without brushstrokes remaining). There are many other uses for this medium, my personal favorite is 2-in-1 Liquitex Gloss Medium and Varnish, you can read my review of this product here. Liquitex brand also has it the Ultra Mate Fluid medium - when you need to avoid any shine or gloss in your artwork.
Glazing Acrylic Medium
Glazing technique in terms of painting refers to the application of few/multiple translucent layers of paint, where each new layer changes or enhances all the previous colors, creating the feel of depth.
So what glazing medium (like Liquitex Professional Glazing Medium) does is it makes acrylic paint thin and transparent without compromising its adhesive properties (like in case of diluting paint with too much water). This medium is milky white when wet, but dries clear.
Pouring Acrylic Medium
Pouring is relatively new, but already extremely popular technique. It's very expressive and colorful, intuitive and bewitching. There are many ways to achieve the runny consistency of a paint, and one of the most effective yet simple ways is by adding the specially designed pouring medium. This medium creates even puddles, poured sheets and flowing applications of color. This Pouring Medium doesn't craze, crack, or hold bubbles in the paint film upon drying. It also usually retains high gloss and wet appearance when dry and doesn't add transparency when mixed with color.
Acrylic Paint can be applied to multiple surfaces, including the clothing fabric. However, if you are planning to wear and wash painted clothes on a regular basis, just a regular paint application will not work for you.
To "lock" the paint into the fabric you will need something like Liquitex Professional Fabric Effects Medium. Another option is Golden Acrylic Medium: Silk Screen Fabric Gel, which is designed to blend with acrylic paints for silk-screen application onto cotton, 50/50 cotton/polyester blend fabrics, and other garments.
Airbrush Acrylic Medium
The name of this medium speaks for itself - it's formulated to thin acrylic colors for airbrush application. Personally, I'm not very familiar with this medium and airbrush technique in general, but I know a few artists who work in this technique, and this is just the whole different world of painting - different tricks and opportunities.
Art truly has no limits!
Retarding Acrylic Medium (Slow Drying)
The drying time of acrylic paint can sometimes be an issue. This is when Retarding Medium like the Liquitex Slow-Dri Medium comes in handy! It's specially designed to keep your painting fresh and can easily add couple hours of open time causing the acrylic to behave a bit more like oil paint. How does it work? It works by slowing the rate at which the water evaporates from the paint. This medium is very useful when you are working on anything that requires a lot of smooth color blending. It's is available in various formulations so you can still have the consistency of paint you want.
Flow Acrylic Medium
Flow improver (or flow aid) is not exactly a medium but rather an additive because unlike all the previous mediums, it's doesn't contain an acrylic polymer emulsion (core ingredient of acrylic paint) and therefore has no binding qualities inherent in it.
This additive is used for dispersing paint, it increases flow and absorption of a paint, decreases film tension and friction, minimizes brush marks. Can be intermixed with any water-soluble paint. medium, ink or dye. I recommend you to check the Liquitex Flow Aid, and there is also another very interesting product from the Golden brand - High Flow Acrylic Paint.
Time to experiment 🙂
Ok, I know it was a long article, but you made it haha! There are so many different mediums out there, I understand that this might be overwhelming, especially for beginners, but you know, take one step at the time. One great option to try many different things is to get a medium sample set, like Fluids Pack, Gel Pack or my favorite Intro Set, that includes Clear Gesso, Slow-Dri Blending Medium, Flexible Modeling Paste, Gloss Super Heavy Gel, Pouring Medium and High Gloss Varnish:
Now, it's time to experiment and to explore new opportunities by extending the expressive potential of your paints. Always make sure to read the label before the use of any medium.
