Understanding Acrylic Mediums: The Basics

What Are Acrylic Mediums?

Alright, let’s start with the million-dollar question: what are acrylic mediums? 

Simply put, acrylic mediums are substances that you mix with acrylic paint to change its properties.

Think of them as magical potions that can transform your paint in all sorts of cool ways!

Acrylic mediums are usually made from the same acrylic polymers as the paint itself, but without the pigment. This means they play nice with your acrylics, blending seamlessly to create all kinds of effects.

Fun Fact: Acrylic paint and mediums were first developed in the 1940s and became popular with artists in the 1960s. Talk about a groovy invention.

The Science Behind Acrylic Mediums

Now, don’t worry – we’re not going to get all Bill Nye the Science Guy here, but understanding a bit about how acrylic mediums work can help you use them more effectively.

Acrylic mediums are like the chameleons of the art world. 

They’re made up of tiny plastic particles suspended in water. When you mix them with paint, these particles get cozy with the paint pigments. 

As the water evaporates, the particles fuse together, creating a flexible film.

Different mediums have different formulations, which is why they can do such a variety of things:

• Some mediums make your paint thicker or thinner

• Others will change how shiny or matte the finish is

• Special types of mediums even add texture or special effects

The cool thing is, once you understand how mediums work, you can start experimenting and creating your own unique effects.

What Are the Different Acrylic Mediums?

Okay, now that we’ve got the basics down, let’s meet the stars of the show.

There are several types of acrylic mediums, each with its own superpower:

  1. Gel Mediums
  2. Modeling Paste
  3. Glazing Mediums
  4. Retarders
  5. Flow Improvers
  6. Matte and Gloss Mediums
  7. Texture Mediums

Each of these mediums has a unique role to play in your artistic toolkit. 

Let’s break them down one by one.

Acrylic Mediums Explained

Gel Mediums

Gel Medium - Acrylic Mediums - Impasto Techniques

Gel mediums are like the muscle-builders of the acrylic world. 

They come in different consistencies (light, regular, and heavy) and finishes (glossy or matte).

Here’s what you can do with them:

  • Add body to your paint for impasto techniques
  • Create transparent layers for depth and dimension
  • Extend your paint without losing color intensity

Pro Tip: Mix gel medium with some paint for a translucent glaze that adds depth to your work!

Modeling Paste

Modeling Paste - Acrylic Medium on Canvas

Modeling paste is your go-to for adding serious texture to your paintings. 

It’s like Play-Doh for grown-ups!

You can:

  • Create 3D effects on your canvas
  • Build up areas for a relief effect
  • Carve into it once it’s dry for unique textures

Fun Fact: Some artists use modeling paste to create entire 3D sculptures on their canvases!

Glazing Mediums

Glazing Medium - Acrylic Medium

Glazing mediums are all about creating those dreamy, translucent layers that add depth and luminosity to your paintings. 

They:

  • Thin your paint without losing its adhesive properties
  • Allow you to build up subtle color variations
  • Create a smooth, even surface for detailed work

Try This: Use a glazing medium to create a “wash” of color over a dry layer for a watercolor-like effect!

Remember: Some glazing mediums contain oil. This glazing medium is incompatible with acrylics, so avoid oil-containing glazing mediums.  

Retarders

Retarders - Acrylic Mediums

Ever wish you could slow down time? Well, retarders are the next best thing! 

They:

  • Slow down the drying time of your acrylics
  • Give you more time to blend and work wet-into-wet
  • Are great for techniques like sgraffito (scratching into wet paint)

Remember: A little goes a long way with retarders. Too much can prevent your paint from drying properly.

Flow Improvers

Flow Improvers - Fluid Paint Art - Pouring Medium - Acrylic Mediums

Flow improvers are like the yoga instructors of the acrylic world – they help your paint relax and flow more freely. 

These mediums:

  • Reduce brush marks for a smoother finish
  • Are great for detailed work and fine lines
  • Can be used to create beautiful “poured” paintings

Flow improvers are also known as Pouring Medium.

Experiment: Try adding a flow improver to your paint for abstract art or fluid painting techniques!

Matte and Gloss Mediums

Gloss Medium - Acrylic Mediums - Acrylic Medium Gloss

These mediums are all about that final look. 

They can:

  • Change the sheen of your paint from matte to glossy (or vice versa)
  • Protect your painting from UV light and dust
  • Enhance color vibrancy (especially with gloss mediums)

Did you know? You can mix matte and gloss mediums to create a custom satin finish!

Pro Tip: You can also use Matte and Gloss Mediums as additives to paste collage paper on your painting surfaces (paper, canvas, or wood). When they dry, they give a matte or glossy transparent look.

Texture Mediums

Texture Medium - Acrylic Mediums

Texture mediums are where things get really fun.

These mediums can add all sorts of wild and beautiful textures to your paintings:

  • Sand texture for a gritty, beachy feel
  • Glass bead gel for a sparkly, dimensional effect
  • Crackle medium for an aged, antique look

The possibilities are endless with texture mediums – let your imagination run wild.

Applications of Acrylic Mediums

What Are Acrylic Mediums Used For?

Now that we’ve met our cast of characters, let’s talk about how to put them to work.

Acrylic mediums have a wide range of applications across different painting styles:

  • Abstract Art: Use texture mediums and modeling paste to create bold, dimensional pieces
  • Realism: Glazing mediums can help you achieve subtle color transitions and fine details
  • Mixed Media: Gel mediums are great for collage and incorporating different materials into your work

Here are some specific ways mediums can change your paint’s behavior:

  • Thickening: Use gel mediums or modeling paste for impasto techniques
  • Thinning: Flow improvers (pouring mediums) or glazing mediums can create wash-like effects
  • Glazing: Build up transparent layers for depth and luminosity
  • Color Vibrancy: Mixing glass medium with acrylic paints will give an extra boost to color and increase the color vibrancy.

Remember, there’s no “right” way to use mediums – experimentation is key.

What Acrylic Mediums Are Waterproof?

Good news for outdoor art lovers – most acrylic mediums are water-resistant once they’re fully cured.

However, some are more durable than others:

  • Gel mediums (especially heavy gel) offer excellent water resistance
  • Gloss mediums create a protective, water-resistant film
  • Some specialty mediums are specifically formulated for outdoor use

To make your acrylic paintings truly weatherproof:

  1. Use a waterproof gesso as a base layer
  2. Apply your paint and mediums as usual
  3. Finish with a UV-resistant varnish for extra protection

Here’s how to turn your acrylic paints into fabric paint:

  1. Mix your acrylic paint with a fabric medium (about 1:1 ratio)
  2. Apply to pre-washed, dry fabric
  3. Let dry completely, then heat-set with an iron

Some tips for fabric painting success:

  • Use a soft brush to avoid stiff, crusty paint
  • Work in thin layers for best results
  • Experiment on scrap fabric first to get a feel for the technique

Fun Project Idea: Try painting a custom design on a plain t-shirt or tote bag.

  • Increasing shine and vibrancy of colors
  • Creating a smooth, even surface
  • Protecting your painting from dust and UV light
