GOLDEN Color Pouring Medium Matte (CPM Matte) is a very new and exciting product for 2019. Unlike most acrylic mediums that develop an initial “skin” when drying, this medium avoids skinning over and therefore is quite resistant to “crazing”. The added benefit is this process allows for air bubbles and tool marks to readily disappear.

In regards to pouring, craze-resistance is important and practical, and it allows more freedom while painting. CPM Matte levels well, creating smooth, uniform paint layers. It can be blended with Heavy Body Acrylics, Fluid Acrylics, or High Flow Acrylics as desired, although starting with relatively low levels of paint (around 10% color) until you gain some experience with the product and its mannerisms is encouraged. The Color Pouring Medium Product Information Sheet has many suggestions to help get you started in the right direction.

Just because it’s designed as a “pouring medium” doesn’t necessarily mean that pouring is the only thing you can do with it or that you can only use CPM Matte in an artwork. There are other uses that make CPM Matte a handy tool to keep in the studio, even if pouring isn’t your thing. You can certainly still use brushes and tools to apply mixtures. Below are but a few of the other ways you can work with it.

Creating Color Fields

Translucent, ethereal color fields are easy to create with CPM Matte and a small addition of acrylic paint. 1-5% paint amounts are great for generating glazes that are both brush stroke free and smooth to the touch. Tone previous paint layers or establish hazy backgrounds. You may brush or blade (or pour, of course) relatively generous layers and watch the tool marks dissipate as the layer relaxes. The glossy wet surface will first level smoothly, and then dry completely matte and flat.

Using CPM Matte with Iridescent and Interference Colors

Almost by accident we discovered that combining mica pigment based paints with this product yielded stunningly beautiful effects. Often the pairing of reflective pigments with matte medium results in disappointment. Try Interference Violet over Black Gesso, or Iridescent Silver over a gray base.

Blend with Color Pouring Medium Gloss to adjust Sheen and Consistency

If the CPM Matte dries too flat – both in terms of sheen and depth – for your taste, you can modify the medium with Color Pouring Medium Gloss (CPM Gloss). In order to add depth without necessarily creating a glossy paint layer, mix 7 parts CPM Matte with 3 parts CPM Gloss.

There’s a handy mixing table that lists what each mixture will dry to in our Product Information Sheet. These blends may then be applied as desired with brush, blade and of course right from the mixing container!

Additionally, if you find the CPM Matte dries too thin for you, add the CPM Gloss to reduce the amount of shrinking. These combinations also aid the CPM Gloss’ flow and leveling, so experiment with how various mixtures behave and not just on the dried finish.

Mix with Gesso to create a Leveling Gesso!

If you abhor sanding primed surfaces (like me) to achieve a smooth gesso coat then give this next application a try: Mix GOLDEN Black or White Gesso with the CPM Matte at 1:1 and apply a relatively generous layer and then lay it flat to dry. The result should be a smooth, flat finish ready for painting. It is important to note that smoother substrates (hardboard, M.D.O. plywood, etc) result in a more uniform Gesso/CPM Matte layer.

This blend will not smooth out texture like canvas weave when it dries. You’ll need to create a smooth surface first and then use the mixture, or you can apply the CPM Gloss first and then cover with the CPM Matte/Gesso mixture. Allow these primer coats plenty of time to dry well (3 days is ideal) prior to painting.

Some Cautionary Guidelines

Golden Artist Colors does a wide array of testing of each product they create. Aside from tests to confirm the robustness of the product as a professional artist tool, Golden further engages in applications testing to push the boundaries of what the products are capable of doing for the artist. As one may suspect, Golden can’t possibly test every single way one might use a new product. Besides, what fun would it be if they didn’t allow our customers the chance to experience the frontier themselves?

However, while testing the Color Pouring Medium Matte, Golden observed some application anomalies they did want to bring to light to insure artists are aware of them and suggest ways to reduce them (or make them!). It is always valuable when experimenting yourself to test your applications before embarking on important projects.

Multiple applications of CPM Matte over highly absorbent surfaces may “mud-crack”

Unsealed supports such as crescent board readily absorb water and other additives in the medium. This may result in “mud-cracking” if the layers are built up thickly. Slow drying, thick puddles of CPM Matte mixtures can develop bubbles under the fresh pour. This is more likely to happen on stretched canvases because the weight of the wet product bows the canvas and creates thick paint pools in the center.

To reduce both mud-cracks and bubbles:

• Use a layer or two of thin glossy acrylic to seal the substrate surface before the buildup of CPM Matte layers.
• Work on a level painting surface. Slight angles will cause the paint to continue to move and create thick edges that dry slower than the rest of the pour.
• Thick layers dry more slowly than thinner ones, and in turn are more likely to facilitate the generation of surface defects.
• Tilt the wet pours to “stretch” the product into a thinner pour.
• Avoid heavy pours unless the excess can flow over the edge later on.
• Try to limit the number of layers, but if you plan to do many pours on one painting, keep them thin.
• Support stretched canvases with underlying panels to reduce thick central pools.
• Thick layers dry more slowly than thinner ones, and in turn are more likely to facilitate the generation of surface defects.
• Allow reasonable drying time between layers of CPMs and before moving onto other types of painting products.

Conclusion

Color Pouring Medium Matte offers some amazing benefits for the artist. Uniform, matte layers free of tool marks has been an elusive research goal for a while. We hope you’ll try this product out and show us new ways to use it.
