7 Ways to Make Acrylics More Opaque

Do you know what I adore the most about acrylic painting? When I feel how the thick acrylic paint covers the canvas and I see the even and opaque surface waiting for me to create something. Honestly, I don’t like translucent colors and always try to learn how to make acrylics more opaque.

how to make acrylics more opaque

To make acrylics more opaque, first of all, check the labels and know what color is opaque or transparent by its nature. Then, you can use special mediums, mix paint with gesso, mix your color with a small amount of Titanium white or even apply a coat of white or carbon black underneath to make acrylics seem more opaque.

Acrylics are made to be more semi-opaque than gouache, e.i. to act more like oil. Opacity is still a tool to correct mistakes and shape objects. Opaque color seems more bright and thick. I love opacity and will share with you 7 easy ways to make your acrylics more opaque, but also we will see what 8 brands and colors are actually more opaque than others.

7 How to make acrylics more opaque

I will start directly with my methods but I highly recommend you to read first the paragraphs about why acrylics are opaque, how to read labels and what pigments are more opaque to be more confident and even start thinking of some own ways to make acrylics more opaque.

I’m mostly creating abstract paintings and using only opaque pigments as white, black, and red. But when I’m creating clouds, sky, beach, and other beautiful pictures that surround me, to make my acrylic paint more opaque, I use these methods:

  1. Titanium White or Carbon Black for mix and cover
  2. Gesso
  3. Special mediums
  4. Multiple layers
  5. Mixing colors
  6. Undiluted paint
  7. Specific paint brands

1 – Add Titanium White or Carbon Black

Titanium White is the most opaque color. The easiest way to make acrylics more opaque is to mix acrylic paint with a small amount of Titanium White. Check other colors in this full list of opaque colors.

Adding white color can be an easy way, but it is also a tricky one. By adding white we will create more pastel colors as white paint tints other colors. Try to add only a small amount and test the color before painting or use the color chart wheel.

You can also paint one good coat of white or black paint before applying the main colors. It will make colors brighter. In fact, it doesn’t affect the opacity of the color but it will create the illusion of opacity as it stops the color underneath from influencing it. 

When you decide to paint over a dark color, the paint will simply disappear without an additional layer of white.

How to make acrylics more opaque

How to apply a layer of Titanium white or Carbon black to increase opacity:

  1. Make sure your previous layer of paint is dry.
  2. Paint another layer of titanium white only where you want to put your transparent color. Let the white dry. Apply black to increase the opacity of semi-opaque colors.
  3. Paint your color over the white or black.

If you apply white or black as the first layer, wait until it’s dried!

2 – Use gesso

Gesso is necessary for the best surface priming. There are 2 options for how you can make acrylics more opaque with gesso:

  1. Apply 3-4 coats of gesso before painting. The gesso should prepare your canvas for painting, it is also can increase color vivacity.

2. Add a bit of gesso to your paint as its ingredients can make your acrylics more opaque.

3 – Add special mediums

In fact, there is almost no medium specifically created to make acrylics more opaque. Still, some brands try to help artists and add to their product range opaque mediums. Honestly, I’d recommend using less expensive alternatives to this method.

If you use fluid acrylics, the best way for you to make acrylics more opaque is to simply use Schmincke Opaque Medium that is created specifically to add opacity to acrylic ink. You can still try to use it with normal paint but it doesn’t work as well with thicker paint as with fluid paint.

The ratio to use Schmincke Opaque Medium is 1/2: 1 medium to paint.

Unfortunately, I could not find it on Amazon or Blick Art.

Another option is Liquitex Ultra Matte Medium. As the brand says, this medium gives acrylic paint an ultra-matte, opaque finish, while thinning and extending its volume. The medium can be used with acrylics and also as underpainting. I didn’t try to mix it with other paint brands and am not sure about the effects I can have.

4 – Number of layers

One of the evident and easiest ways to make acrylics more opaque is painting more layers. Each new layer interacts with the last one: new layers make the color more opaque naturally.

Some precautions here:

  • don’t overdo. It is still a painting and not a cake.
  • paint over only a fully dried layer. The shift in drying between layers can cause cracking.
  • know the color chart and how pigments work. Even 5 layers of green over Carbon black will make no difference.

5 – Mixing colors

Another natural way to make colors more opaque, stronger, and brighter is to mix them with another opaque color.

Moreover, colors like orange and violet are stronger when you mix them by yourself and not using orange pigment directly from the tube.

By mixing colors on your own, you control the opacity by adding white, for example.

This method perfectly works not only to create more opaque colors but in the opposite way too – to make transparent and light colors.

6 – Use undiluted paint

Every time you dilute the paint with distilled or tap water or acrylic mediums you slightly destroy the pigment and paint adhesion. As the result, you will have a more transparent color, more fluidity, and thinner paint. The more diluted paint is, the less opaque it is.

To make acrylics more opaque use undiluted paint.

7 – Use specific paint brands

As I always say, make notes. With experience and knowledge, you are very likely to find the best opaque paint for you.

In general, artist-grade acrylic paint has higher pigment and it makes the color stronger and increases hiding properties. But it doesn’t mean that the paint will be more opaque. Below I will make a list of opaque pigments.

Read the label and if it says "Professional" or "Artist's" - it is an artist-grade acrylic paint. 

There is no specific brand or product line that is meant to be only opaque, but I know 8 brands that are more likely to be what you’re looking for.

You will also discover that this green is more opaque with this brand, but the yellow is better with another one. Just swap and create your own range!


8 Best opaque acrylic paint

Based on my experience and researches I can share with you the list of most likely opaque paint. But again I’d like to emphasize that opacity varies and depends on specific pigment more than on brand.

What is opaque paint?

what is an opaque paint

Opaque paint is paint that is not transparent. It is one of the characteristics of the paint based on the pigment and light absorbency.

Opaque colors do not allow light to pass through the color, they reflect the light, and offer the best coverage and hiding properties.

There is also semi-opaque paint which allows some light to go through the coat.

In general, each brand will mention it on the label. Artist-grade paint is supposed to be more opaque than student-grade as professional paint contains more pigment.

What colors are opaque

Why is my acrylic paint not opaque?

The opacity can vary from brand to brand. Some paint will be more opaque. Some pigments are also naturally more translucent than others as Quinacridone, Naphthamide, Phthalo, Hansa, and Anthraquinone.

The opacity of a chosen color is determined by several factors:

  • size of the pigment particles.
  • thickness of the paint layer.
  • amount of medium used with the paint.
  • refraction indices of the pigment. High refractive = high opacity.

How to read labels to learn about opacity

Most paint manufacturers will indicate the opacity of each product. You can easily understand it, but be aware that the best way to test the opacity of your acrylic is to make a quick paint test on paper, using all colors and trying to cover black with them, e.i.:

Here are some examples of different brands:

  • small circles. If the circle is filled, it means the color is opaque, empty circle stands for transparent and half-filled for semi-opaque or semi-transparent color. Atelier Interactive paint has it:
  • a catalog with hand-painted colors where you can see the actual opacity like Daler Rowney, Cryla Artist Color do
  • a letter, e.i. “t” for transparent
